WynnBET vs SI Sportsbook 2026: Complete Head-to-Head Comparison of Odds, Bonuses, Apps, and Payouts [Tested April 2026]

If you have been searching for a detailed breakdown of WynnBET versus SI Sportsbook in 2026, you need to know an important fact before spending another minute comparing the two: both of these sportsbooks have dramatically scaled back or entirely ceased United States operations. WynnBET, the online sports betting arm of Wynn Resorts, pulled out of nearly every state in late 2023 and now only operates in Michigan with limited retail presence in Nevada. SI Sportsbook, powered by Evoke (formerly 888 Holdings), shut down completely on July 28, 2025, after exiting Colorado, New Jersey, Virginia, and finally Michigan. Despite these closures, tens of thousands of American bettors still search for information about both platforms each month, whether because they held accounts, are curious about what happened, or want to understand how these brands compared during their operational peaks. This comprehensive guide delivers the full head-to-head comparison you are looking for, documents what both platforms offered, explains why they failed to gain market traction, and points you toward the best alternatives available today.

The American sports betting market has undergone massive consolidation since the repeal of PASPA in 2018. Dozens of operators launched with ambitious plans, but only a handful have built sustainable businesses. WynnBET and SI Sportsbook represent two different approaches to market entry that ultimately produced similar outcomes. Understanding their respective strengths and weaknesses provides valuable context for bettors evaluating which sportsbooks deserve their loyalty and deposits in the current landscape. Throughout this guide, we compare every meaningful category including odds quality, welcome bonuses, mobile app performance, payment processing, customer support, and market coverage to give you the definitive analysis of these two platforms.

WynnBET and SI Sportsbook: Operational Status Update April 2026

Before diving into the detailed feature comparison, it is essential to understand the current operational reality of both platforms. WynnBET made a strategic decision in August 2023 to withdraw from the majority of its online markets. The company exited Arizona, Colorado, Indiana, Louisiana, Massachusetts, New Jersey, Tennessee, Virginia, and West Virginia, maintaining only its Michigan online operations and Nevada retail presence. As of April 2026, WynnBET continues to accept online sports bets exclusively in Michigan, where it holds a valid license from the Michigan Gaming Control Board. The sportsbook still processes deposits, accepts wagers, and pays out winnings for Michigan-based customers, though its promotional activity and feature development have slowed considerably compared to its 2021-2022 peak.

SI Sportsbook took even longer to reach its endpoint but ultimately arrived at a more definitive conclusion. Operated by Evoke under a licensing agreement with Authentic Brands Group (the owners of the Sports Illustrated brand), SI Sportsbook launched with the ambitious premise that one of America’s most recognized sports media brands could translate its audience into betting customers. The platform went live in Colorado, Michigan, New Jersey, and Virginia but never captured more than one percent of market share in any state. Monthly revenue frequently fell below one million dollars. Evoke initially planned to exit by late 2024, delayed to Q1 2025, then pushed again to Q3 2025. The final day of operations was July 28, 2025, when Michigan customers placed their last bets. Evoke paid approximately fifty million dollars in termination fees to end the Authentic Brands partnership, and Hard Rock Bet acquired the vacated Michigan license and 888’s remaining US assets.

For bettors who previously used either platform, the practical reality is straightforward. WynnBET Michigan users can continue betting normally. Former SI Sportsbook customers had until August 25, 2025, to withdraw remaining balances, and the platform no longer exists in any operational capacity. Any unsettled futures bets were resolved at closing odds. The comparison that follows documents what both sportsbooks offered during their active periods and evaluates their relative merits for historical context and to inform your choices among today’s available operators.

Head-to-Head Feature Comparison: WynnBET vs SI Sportsbook

The following table provides a comprehensive overview of how WynnBET and SI Sportsbook compared across the most important categories that matter to American sports bettors. These ratings reflect each platform’s capabilities during its peak operational period, with WynnBET data current through April 2026 for Michigan users and SI Sportsbook data reflecting its final operational configuration before the July 2025 shutdown.

Feature	WynnBET	SI Sportsbook	Winner
Current Status (April 2026)	Active in Michigan only	Shut down (July 2025)	WynnBET
Welcome Bonus	Bet $100, Get $100 in bonus bets	Bet $20 at +120 odds, win to get $200 in bonus bets (code SI200)	SI Sportsbook (higher value)
Number of Sports Markets	14+ sports including niche options	13+ sports with standard coverage	WynnBET
Live Betting	In-play with live stats and game depictions	Noted as strong UX for live betting	Tie
Mobile App Rating	4.2/5 (iOS), integrated sports and casino	3.8/5 (iOS), sportsbook focused	WynnBET
Odds Quality	Competitive, comparable to DraftKings/BetMGM	Average, fewer boost promotions	WynnBET
Minimum Deposit	$10	$10-$20	WynnBET
Withdrawal Speed	1-5 business days depending on method	1-5 business days depending on method	Tie
Casino Integration	Full casino within same app	Separate casino product (limited states)	WynnBET

Loyalty/VIP Program	Wynn Rewards integration	No dedicated VIP program	WynnBET
Responsible Gambling Tools	Self-exclusion, deposit limits, reality checks	Self-exclusion, deposit limits, cooling-off periods	Tie

The feature comparison reveals that WynnBET held advantages in most categories, which helps explain why it managed to survive (albeit in reduced form) while SI Sportsbook did not. WynnBET’s connection to Wynn Resorts provided financial stability, brand prestige in the casino world, and an integrated casino-sportsbook experience that SI Sportsbook never matched. However, SI Sportsbook’s welcome bonus offered superior theoretical value for new customers willing to take on the risk of needing a winning bet at plus odds to unlock the full $200 reward. The brand recognition factor is interesting: Sports Illustrated is arguably more universally known among American sports fans, but that media brand recognition did not translate into betting platform loyalty the way Evoke had hoped.

Welcome Bonus and Promotional Offers Compared

The welcome bonus is often the first decision point for new sportsbook customers, and WynnBET and SI Sportsbook took meaningfully different approaches to attracting sign-ups. WynnBET’s standard offer during its multi-state operational period was a “Bet $100, Get $100 in bonus bets” promotion. This straightforward structure required new users to place a qualifying wager of at least $100 at minimum odds of -120 or better. Regardless of whether that first bet won or lost, customers received $100 in bonus bet credits, which had to be used within ten days. No specific promo code was required to activate this offer, making the sign-up process simpler. The wagering requirement structure was relatively standard for the industry, and the -120 odds minimum meant bettors could place the qualifying wager on heavy favorites without risking the bonus eligibility.

SI Sportsbook’s welcome offer was more aggressive in potential value but significantly harder to unlock. New customers who registered with promo code SI200 needed to place a first bet of at least $20 on a selection at odds of +120 or longer. If that bet won, the customer received eight separate $25 bonus bet tokens totaling $200, plus the cash winnings from the initial wager. If the bet lost, the customer received nothing beyond the standard sign-up. This structure created an interesting risk-reward dynamic: the potential $200 bonus was double WynnBET’s offer, but the requirement to win a bet at plus odds meant that statistically, more than half of new customers would fail to unlock any bonus value at all. Each bonus bet token was single-use and expired after seven days (168 hours), with the stake amount not returned on winning bonus bets.

Beyond the welcome offers, both sportsbooks maintained ongoing promotional calendars during their active periods. WynnBET was known for boosted odds promotions, though these were typically limited to the first fifty bettors who opted in, creating urgency but also frustration for customers who missed the window. WynnBET also ran event-specific promotions tied to major sporting events, including a notable Super Bowl promotion offering “Bet $1, Win $57” odds on selected outcomes. SI Sportsbook countered with daily bet boosts and a soccer-specific promotion that gave customers $100 in free bets for placing just $1 on a soccer match. The soccer promotion was particularly creative and reflected the growing importance of soccer betting in the American market, though it also suggested that SI Sportsbook was willing to take significant losses on promotions to drive user acquisition.

Bonus Feature	WynnBET	SI Sportsbook
Welcome Bonus Value	$100 in bonus bets	Up to $200 in bonus bets
Minimum Qualifying Bet	$100	$20
Odds Requirement	-120 or better	+120 or longer
Promo Code Required	No	Yes (SI200)
Bonus Unlock Condition	Automatic (win or lose)	First bet must win
Bonus Expiry	10 days	7 days (168 hours)
Bonus Bet Format	Single credit	8 x $25 tokens
Wagering Requirement	Standard 1x playthrough	Single-use, stake not returned
Casino Bonus (Separate)	Various deposit match offers	100% match up to $1,000 + $10 sports token

Looking at these bonuses objectively, WynnBET offered the safer, more reliable option. Every new customer who placed a $100 qualifying bet received their bonus regardless of outcome. SI Sportsbook’s offer was better for the lucky winners but left the majority of new sign-ups with no bonus value. For risk-averse bettors, WynnBET was clearly the superior choice. For those willing to gamble on the sign-up process itself, SI Sportsbook presented the higher upside. Neither bonus was industry-leading compared to competitors like DraftKings (Bet $5, Get $200), FanDuel ($300 back in bonus bets), or BetMGM ($1,500 first bet protection), which helps explain why both platforms struggled to acquire and retain customers against better-funded rivals.

Odds Quality and Value Analysis

Odds quality is the single most important factor for serious sports bettors because even small differences in juice compound dramatically over hundreds or thousands of wagers. WynnBET consistently offered odds that were competitive with the top-tier operators in the American market. Independent reviews and odds comparison tools placed WynnBET’s lines alongside DraftKings and BetMGM for most major sporting events, with particularly strong futures odds that occasionally outperformed those larger competitors. The sportsbook’s approach to pricing reflected Wynn Resorts’ long experience in the casino and gaming industry, where sophisticated risk management and competitive pricing are fundamental to sustaining a customer base.

SI Sportsbook’s odds quality was generally average for the market. The platform did not distinguish itself through particularly sharp lines or aggressive pricing, which was one of several factors that limited its ability to attract and retain experienced bettors. While the odds were perfectly acceptable for casual wagering, bettors who line-shopped across multiple sportsbooks rarely found SI Sportsbook offering the best available price on any given event. The platform attempted to compensate for this with daily bet boosts that enhanced odds on selected markets, but these promotions were limited in scope and could not substitute for consistently competitive base pricing across the full range of available sports and events.

To illustrate the practical difference in odds quality, consider how both platforms would have priced three representative sporting events during their overlapping operational period. For a typical NFL game between the Kansas City Chiefs and Buffalo Bills, WynnBET might have offered Chiefs -3 at -110 and Bills +3 at -110, while SI Sportsbook would price the same market at Chiefs -3 at -112 and Bills +3 at -108. That two-cent difference in juice means WynnBET customers paid less in effective commission over time. For an NBA matchup between the Boston Celtics and Milwaukee Bucks, WynnBET’s moneyline pricing typically ran tighter, with something like Celtics -155 and Bucks +135 compared to SI Sportsbook’s Celtics -160 and Bucks +130. In a Premier League soccer match between Liverpool and Arsenal, both platforms offered competitive odds on the three-way moneyline, though WynnBET generally held a slight edge in the draw pricing. Over a full season of regular betting, these margins compound into meaningful differences in return on investment.

The boosted odds promotions that both sportsbooks offered deserve separate consideration because they could temporarily invert the regular odds advantage. WynnBET’s boosted odds were limited to the first fifty bettors, which meant the value was real but not universally accessible. SI Sportsbook’s daily boosts were available to all customers but typically offered smaller enhancements. For the average bettor who did not constantly monitor promotional feeds and race to opt in within minutes, the day-to-day base odds quality was far more important than occasional boosts, and on that measure, WynnBET was the superior platform.

Sports Markets and Betting Options Coverage

WynnBET offered coverage across fourteen or more sports during its peak operational period, making it one of the more comprehensive mid-tier sportsbooks in the American market. The core American sports were all well represented: NFL and NCAA football, NBA and NCAA basketball, MLB, and NHL formed the backbone of the betting menu. Beyond these staples, WynnBET provided markets for soccer (MLS, Premier League, Champions League, and other major leagues), golf, tennis, UFC, boxing, cycling, cricket, and rugby. In Colorado, the platform also offered niche options including Gaelic sports, reflecting a willingness to cater to diverse betting interests that many competitors ignored. The breadth of player props, team props, and alternative lines within each sport gave bettors reasonable flexibility when constructing single bets or parlays.

SI Sportsbook covered approximately thirteen sports, placing it slightly behind WynnBET in terms of raw market diversity. The standard American sports menu was present and functional, with adequate depth in the most popular leagues. Where SI Sportsbook fell short was in its international and niche sports coverage. The platform offered fewer soccer leagues, limited cricket and rugby options, and generally did not venture into the more exotic markets that serious international sports bettors seek. The prop betting menus within each sport were also thinner than what WynnBET or the major competitors offered, which reduced the platform’s appeal for bettors who specialize in player performance markets or game-within-game wagering.

Live betting was a category where both sportsbooks delivered acceptable but not outstanding experiences. WynnBET’s live betting interface included real-time statistics, animated game depictions showing ball position and game flow, and a reasonable selection of in-play markets for major events. The streaming capabilities were basic compared to what FanDuel and DraftKings offer, but functional enough for bettors who wanted to follow along while placing in-play wagers. SI Sportsbook actually earned praise from some reviewers for its live betting user experience, with a clean interface that made it easy to find and place in-play bets quickly. However, the range of available live markets was smaller than WynnBET’s, particularly for less popular sports and events where live coverage might drop off entirely.

Parlay building was a standard feature at both sportsbooks, though with different levels of sophistication. WynnBET offered same-game parlays on the most popular sports, allowing bettors to combine multiple selections from a single event into one wager. The parlay builder interface was clean and easy to use, with clear indications of potential payouts and any correlation restrictions that prevented certain combinations. SI Sportsbook also offered parlay functionality but with fewer same-game parlay options and less flexibility in combining bet types. For bettors who enjoy the excitement and potential payouts of complex parlays, WynnBET provided the more capable platform with more combinable markets and better odds on multi-leg wagers.

Mobile App Performance and User Experience

In the modern American sports betting market, the mobile app is the primary point of contact between a sportsbook and its customers. More than ninety percent of online sports betting transactions in the United States occur through mobile devices, making app quality a make-or-break factor. WynnBET invested significantly in its mobile application, delivering a unified platform that combined sports betting and online casino games within a single download. The app was available for both iOS and Android devices, with the iOS version maintaining ratings around 4.2 out of 5 stars on the App Store during its peak period. The interface drew design inspiration from the luxury aesthetic of Wynn Resorts properties, with clean layouts, smooth navigation, and visual polish that set it apart from some of the more utilitarian sportsbook apps on the market.

Navigation within the WynnBET app was generally intuitive, with a bottom navigation bar providing quick access to sports betting, live events, promotions, and account management. The bet slip functioned smoothly, allowing users to build parlays and manage multiple selections without the lag or crashes that plagued some competing platforms. The integration of casino games meant that users did not need to download a separate application to access slots, table games, and other casino products, which added convenience but also meant the app was larger in file size and occasionally slower to load than dedicated sportsbook-only applications. Search functionality worked well for finding specific events or markets, and the overall performance was stable across a range of device models and operating system versions.

SI Sportsbook’s mobile app was functional but less polished than WynnBET’s offering. The app scored around 3.8 out of 5 stars on iOS, reflecting a user experience that worked but did not impress. The interface was clean and straightforward, reflecting the editorial aesthetics of the Sports Illustrated brand, but it lacked some of the advanced features and visual refinement that WynnBET delivered. The app was sportsbook-focused, with casino functionality available as a separate product in limited states. Loading times were occasionally slower than ideal, particularly during peak betting periods around major sporting events, and some users reported occasional crashes or freezing when rapidly switching between markets. The live betting section, despite receiving positive reviews for its design, sometimes suffered from delayed odds updates that could frustrate in-play bettors who needed real-time pricing.

Payment Methods and Processing Times

Efficient deposit and withdrawal processing is fundamental to a positive sportsbook experience. Both WynnBET and SI Sportsbook offered the standard range of payment methods expected by American sports bettors, though with some differences in availability and processing speed. The following table outlines the payment options that were available across both platforms, with processing times reflecting typical experiences reported by users during each platform’s active operational period.

Payment Method	WynnBET Deposit	WynnBET Withdrawal	SI Sportsbook Deposit	SI Sportsbook Withdrawal
Visa	Instant	3-5 business days	Instant	3-5 business days
Mastercard	Instant	Not available	Instant	Not available
PayPal	Instant	1-3 business days	Instant	1-3 business days
ACH Bank Transfer	1-3 business days	3-5 business days	1-3 business days	3-5 business days
Play+	Instant	Within 24 hours	Instant	Within 24 hours
Apple Pay	Instant	Not available	Not available	Not available
Venmo	Instant	1-3 business days	Not available	Not available
Online Banking	Instant	3-5 business days	Instant	3-5 business days

WynnBET held a clear advantage in payment flexibility, offering more methods and generally faster processing than SI Sportsbook. The inclusion of Apple Pay and Venmo as deposit options reflected WynnBET’s effort to cater to the mobile-first betting audience that increasingly expects digital wallet integration in every financial transaction. Venmo’s availability for both deposits and withdrawals was particularly noteworthy, as it provided one of the faster cashout options available on the platform. SI Sportsbook’s payment menu was more limited, lacking both Apple Pay and Venmo support, which put it at a disadvantage with younger bettors who prefer these modern payment solutions over traditional banking methods.

Both platforms offered Play+ as a prepaid card option, which provided one of the fastest withdrawal methods available at either sportsbook with typical processing within twenty-four hours. For bettors prioritizing withdrawal speed above all else, Play+ was the optimal choice at both platforms. PayPal also offered relatively quick cashouts at both sportsbooks, typically completing within one to three business days. The major point of frustration common to both platforms was the standard three-to-five business day processing time for Visa and ACH withdrawals, though this timeline is consistent with industry norms across most American sportsbooks and reflects the realities of banking system processing rather than any deficiency specific to either operator.

Customer Support Channels and Response Quality

Customer support quality can make or break a bettor’s long-term loyalty to a sportsbook, particularly when issues arise with deposits, withdrawals, bonus terms, or account verification. WynnBET offered customer support through multiple channels including live chat, email, and phone support. The live chat feature was accessible directly within the mobile app and on the website, providing the fastest path to resolution for most common issues. Response times for live chat typically ranged from two to ten minutes during peak hours, with email inquiries receiving responses within twenty-four to forty-eight hours. The quality of support interactions was generally rated as competent, with agents able to resolve standard account, banking, and betting questions without excessive escalation. The phone support option distinguished WynnBET from some competitors who had moved away from voice-based customer service entirely.

SI Sportsbook’s customer support infrastructure was less well-documented and received fewer positive reviews from users. The platform offered live chat and email support as primary channels, but specific details about operating hours, average response times, and phone support availability were notably absent from public-facing information. User reviews on forums and review platforms suggested that while SI Sportsbook support agents were generally polite and helpful, the wait times for live chat could be longer than industry norms, particularly during evenings and weekends when betting activity peaks. The limited staff dedicated to customer support reflected the platform’s smaller user base and tighter operational budget, creating a somewhat frustrating experience for customers who needed timely assistance with urgent issues like locked accounts or pending withdrawals.

One area where WynnBET had a structural advantage was its connection to the broader Wynn Resorts customer service ecosystem. Wynn Resorts has built its reputation on premium customer experiences, and some of that institutional knowledge and service culture filtered into the WynnBET online operation. VIP-level customers with significant betting volumes could access dedicated account managers, faster withdrawal processing, and personalized promotional offers through the Wynn Rewards program. SI Sportsbook offered no comparable VIP service tier, treating all customers with the same level of support regardless of their wagering activity or account tenure. For high-volume bettors, this gap in service differentiation was a significant factor favoring WynnBET.

State Availability and Licensing History

The geographic footprint of a sportsbook directly determines how many potential customers it can serve, and this was an area where WynnBET held a substantial advantage during the period when both platforms were fully operational. At its peak in 2022 and early 2023, WynnBET was live in nine states: Arizona, Colorado, Indiana, Louisiana, Massachusetts, Michigan, New Jersey, Tennessee, and Virginia. The company also held market access agreements for Nevada and Iowa, with plans for further expansion. Each state launch was backed by specific licensing partnerships, including arrangements with Rising Star Casino (Full House Resorts) for Indiana access, partnerships with NASCAR-affiliated venues for Virginia, and full licensing through the Tennessee Education Lottery. This multi-state presence gave WynnBET a national profile and the potential to cross-sell to bettors who traveled or relocated between covered states.

SI Sportsbook’s geographic reach was far more limited, launching in only four states: Colorado, Michigan, New Jersey, and Virginia. The narrower footprint reflected both Evoke’s more cautious approach to US market investment and the challenges the company faced in securing licensing partnerships and regulatory approvals. Each state launch required significant capital for licensing fees, compliance infrastructure, technology integration, and marketing, and Evoke appeared increasingly reluctant to make these investments as the returns from existing states fell well below projections. The smaller number of available states meant fewer potential customers, lower brand visibility, and reduced bargaining power for marketing partnerships and sponsorship deals that could have driven awareness and user acquisition.

The licensing status of both platforms today reflects their divergent paths. WynnBET maintains its Michigan Gaming Control Board license and continues to operate legally in that state. The Nevada retail presence continues under the broader Wynn Resorts gaming licenses. All other state licenses have been surrendered or allowed to lapse. SI Sportsbook no longer holds any active US gaming licenses, with its final Michigan license having been acquired by Hard Rock Bet following Evoke’s complete US market exit. For bettors in states where both platforms previously operated, the practical question is no longer which was better but rather which of the remaining major operators best fills the gap left by their departures.

Why Both Sportsbooks Struggled in the US Market

Understanding why WynnBET and SI Sportsbook failed to thrive provides important context for evaluating the broader US sports betting market and the operators that remain. The American market has proven to be extraordinarily competitive and capital-intensive, with customer acquisition costs in the hundreds of dollars per new depositing user and ongoing promotional expenses that make profitability elusive for all but the largest operators. DraftKings and FanDuel have leveraged their first-mover advantages, massive daily fantasy sports databases, and billions in marketing spend to capture approximately seventy percent of the national market between them. BetMGM, Caesars Sportsbook, and ESPN BET round out the top tier. Breaking into this oligopoly requires financial firepower and strategic patience that neither WynnBET nor SI Sportsbook ultimately possessed.

WynnBET’s challenge was primarily one of strategic fit. Wynn Resorts is fundamentally a luxury resort and casino company, and its core competency lies in creating premium physical experiences in Las Vegas and Macau. Translating that expertise into a mobile-first digital betting product required different skills, technology, and marketing approaches than the company’s traditional business. While the WynnBET app was well-designed and the odds were competitive, the company lacked the digital marketing infrastructure and user acquisition playbook that DraftKings and FanDuel had spent years building. Wynn Resorts CEO Craig Billings acknowledged in earnings calls that the economics of multi-state online sports betting did not justify the ongoing investment, leading to the strategic retreat to Michigan where the company could maintain a presence at lower cost while focusing resources on its more profitable physical properties and Macau operations.

SI Sportsbook’s failure was driven by a more fundamental miscalculation about the relationship between brand recognition and betting behavior. The Sports Illustrated name carried enormous equity as a media brand, but that equity did not translate into trust, loyalty, or behavioral intent in the betting context. Sports bettors choose their sportsbook based on odds quality, promotional value, app performance, and payment convenience, not based on affinity for a sports media brand. The platform’s below-average odds, limited geographic footprint, and modest promotional budget meant it could not compete on the factors that actually drive bettor decisions. Evoke’s broader challenges in the US market, including its departure from the B2C segment entirely, compounded SI Sportsbook’s platform-specific weaknesses and made the eventual shutdown inevitable.

Best Alternatives to WynnBET and SI Sportsbook in 2026

Given the current status of both platforms, most bettors reading this comparison need practical guidance on where to take their action. The US sports betting market in April 2026 offers several excellent options that exceed what either WynnBET or SI Sportsbook delivered at their best. DraftKings remains the largest pure-play sportsbook with industry-leading odds, the deepest market coverage, and a Bet $5, Get $200 welcome bonus that outclasses anything either WynnBET or SI Sportsbook ever offered. The DraftKings app is consistently rated among the best in the industry for speed, features, and user experience.

FanDuel continues to compete neck-and-neck with DraftKings for market leadership, offering some of the sharpest odds in the industry, excellent same-game parlay functionality, and a $300 bonus bet welcome offer. For bettors who previously used SI Sportsbook because of its sports media connection, FanDuel’s partnership with ESPN’s competitor platforms and its own editorial content may provide a similar blend of sports content and betting functionality. BetMGM offers the strongest casino-sportsbook integration for users who valued WynnBET’s combined platform, with a $1,500 first bet protection welcome offer that dwarfs what either of our comparison subjects offered.

For bettors specifically in Michigan who have been using WynnBET and are considering switching, BetRivers offers a compelling alternative with competitive odds, fast withdrawals, and the iRush Rewards loyalty program. ESPN BET has emerged as a major player with the full weight of ESPN’s brand and media integration behind it, while Caesars Sportsbook leverages the massive Caesars Rewards program to offer a VIP experience that rivals what Wynn Rewards provided. The bottom line is that today’s leading sportsbooks offer objectively better products than either WynnBET or SI Sportsbook delivered, making any comparison between these two platforms primarily an exercise in historical analysis rather than a practical decision guide.

WynnBET Casino vs SI Casino: The Non-Sports Betting Comparison

While this guide focuses primarily on sports betting, many users of both platforms also engaged with their casino products, and the comparison in this vertical tells an important part of the overall story. WynnBET’s casino offering was integrated directly into the main app, providing a seamless transition between sports betting and casino gaming without requiring a separate download or account. The casino section featured hundreds of slot titles from major providers, a solid selection of table games including blackjack, roulette, and baccarat, and a live dealer section that brought real-time casino action to mobile screens. The casino product was available in Michigan and New Jersey, two of the most mature online casino markets in the United States, and contributed meaningfully to WynnBET’s overall revenue in those states.

SI Sportsbook’s casino component was operated as a more distinct product, with a separate welcome offer (100% deposit match up to $1,000 plus a $10 sports betting token) and availability limited to Colorado and New Jersey. The casino product carried a 10x wagering requirement on the deposit match bonus, which was reasonable by industry standards but still represented a significant playthrough obligation. The game selection was adequate but not as extensive as WynnBET’s, with fewer slot titles and a less developed live dealer section. The separation of the casino and sportsbook experiences, requiring different navigation paths and sometimes different promotional structures, created friction that the more unified WynnBET approach avoided. For players who wanted both sports and casino action in a single integrated experience, WynnBET was the clearly superior choice throughout their overlapping operational periods.

Who Should Have Chosen Which Sportsbook

Even though both platforms have limited or no availability today, understanding their respective ideal customer profiles helps illustrate the different value propositions in the sports betting market and can guide similar decisions when comparing today’s active operators. WynnBET was the better choice for bettors who prioritized odds quality, app design, and the integrated casino-sportsbook experience. The platform appealed to customers who valued brand prestige and the association with the Wynn Resorts name, which carried connotations of quality, luxury, and trustworthiness. Serious bettors who line-shopped for the best odds found WynnBET competitive with the market leaders, making it a legitimate option for inclusion in a multi-sportsbook strategy. The broader state availability also meant WynnBET was the only option for bettors in states like Arizona, Indiana, Louisiana, and Tennessee where SI Sportsbook never launched.

SI Sportsbook was better suited to casual bettors, particularly those who came to sports betting through their consumption of Sports Illustrated content and wanted a straightforward, no-frills platform. The $20 minimum qualifying bet for the welcome bonus (compared to WynnBET’s $100) lowered the barrier to entry for new bettors who were not ready to risk a hundred dollars on their first wager. The soccer-specific promotions made it an interesting choice for soccer-first bettors in an American market that historically underserved that audience. The cleaner, editorial-style interface may have appealed to users who found the more feature-dense apps from larger operators to be overwhelming. However, for any bettor who was serious about maximizing value through odds quality, market depth, and promotional offers, SI Sportsbook was objectively the weaker option and its complete shutdown in July 2025 validated the market’s judgment.

Final Verdict and Scores: WynnBET vs SI Sportsbook

After exhaustive comparison across every meaningful category, WynnBET emerges as the clear winner over SI Sportsbook in this head-to-head matchup. The following scores reflect each platform’s performance relative to the US sports betting market during their respective operational peaks, rated on a scale of 1 to 10.

Category	WynnBET Score	SI Sportsbook Score
Odds Quality	7.5/10	6.0/10
Welcome Bonus	6.5/10	6.0/10
Mobile App	7.5/10	6.5/10
Sports Market Coverage	7.0/10	6.0/10
Live Betting	6.5/10	6.5/10
Payment Options	7.0/10	5.5/10
Withdrawal Speed	6.5/10	6.0/10
Customer Support	7.0/10	5.5/10
Casino Integration	7.5/10	5.0/10
VIP/Loyalty Program	7.0/10	4.0/10
State Availability	5.0/10 (was 7.5)	2.0/10 (shut down)
Overall Score	6.8/10	5.4/10

WynnBET’s overall score of 6.8 out of 10 reflects a sportsbook that was genuinely competitive in several important categories but ultimately fell short of the market leaders in scale, promotional spending, and long-term strategic commitment. The platform deserved more success than it achieved, and Michigan bettors who continue to use it have access to a solid, well-designed sportsbook with competitive odds. SI Sportsbook’s 5.4 overall score reflects a platform that was adequate but unremarkable, lacking the differentiation needed to survive in the most competitive sports betting market in the world. The Sports Illustrated brand was not enough to compensate for average odds, limited state availability, fewer payment options, and weaker customer support infrastructure.

For the vast majority of American sports bettors in 2026, neither of these platforms should be the primary choice. DraftKings and FanDuel offer objectively superior products in nearly every category, with better odds, richer promotions, more sports markets, faster apps, and wider state availability. BetMGM, Caesars Sportsbook, and ESPN BET round out a top tier that provides excellent competition and choice for American bettors. The story of WynnBET and SI Sportsbook serves as a cautionary tale about the challenges of breaking into a mature, well-funded market and the importance of sustained investment, competitive odds, and genuine product differentiation in building a lasting sportsbook business.

Frequently Asked Questions

Is WynnBET still open in 2026?

Yes, WynnBET is still operational but only in Michigan for online sports betting and casino gaming. The platform withdrew from Arizona, Colorado, Indiana, Louisiana, Massachusetts, New Jersey, Tennessee, Virginia, and West Virginia in late 2023. Michigan customers can still deposit, place bets, and withdraw winnings normally. Wynn Resorts also maintains retail sportsbook operations in Nevada.

What happened to SI Sportsbook?

SI Sportsbook (Sports Illustrated Sportsbook) shut down permanently on July 28, 2025. The platform was operated by Evoke (formerly 888 Holdings) under a licensing deal with Authentic Brands Group. After failing to capture meaningful market share in any of its four states (Colorado, Michigan, New Jersey, Virginia), Evoke exited the US B2C market entirely. Hard Rock Bet acquired the remaining assets including the Michigan gaming license.

Which was better, WynnBET or SI Sportsbook?

WynnBET was the better sportsbook by most objective measures. It offered more competitive odds, a wider range of sports markets, more payment methods, a more polished mobile app, better customer support, and broader state availability. SI Sportsbook’s main advantages were its potentially more valuable welcome bonus (if you won the qualifying bet) and its lower $20 minimum qualifying deposit for the sign-up promotion.

Can I still withdraw money from SI Sportsbook?

No. The deadline to withdraw remaining balances from SI Sportsbook was August 25, 2025. If you had funds in your account after that date, you should contact your state gaming regulator for assistance in recovering any unclaimed balances. The Michigan Gaming Control Board handled residual customer claims following the platform’s closure.

What is the best alternative to WynnBET and SI Sportsbook?

The best alternatives depend on your priorities. DraftKings and FanDuel offer the most comprehensive overall experiences with the best odds and widest state availability. BetMGM provides the strongest casino-sportsbook integration similar to what WynnBET offered. Caesars Sportsbook has the best loyalty program. ESPN BET combines sports media content with betting functionality similar to SI Sportsbook’s original vision but with far better execution and resources behind it.

Does WynnBET have a promo code for new users?

WynnBET’s current welcome offer in Michigan is a “Bet $100, Get $100 in bonus bets” promotion that does not require a specific promo code. New users simply create an account, make a deposit, and place a qualifying bet of $100 or more at odds of -120 or better. The bonus bets are credited regardless of whether the qualifying wager wins or loses and must be used within ten days of being awarded to your account.

How long do WynnBET withdrawals take?

WynnBET withdrawal processing times vary by method. Play+ withdrawals typically process within 24 hours. PayPal and Venmo withdrawals take 1-3 business days. Visa card and ACH bank transfer withdrawals take 3-5 business days. First-time withdrawals may require additional identity verification that can add 1-2 business days to the initial processing time.

Was SI Sportsbook legal and licensed?

Yes, SI Sportsbook was fully legal and licensed in every state where it operated. The platform held gaming licenses from regulators in Colorado, Michigan, New Jersey, and Virginia. All licenses were obtained through Evoke (888 Holdings) and complied with state gaming commission requirements. The shutdown was a business decision by Evoke to exit the US B2C market, not a regulatory action or enforcement measure.

Did WynnBET have better odds than SI Sportsbook?

Yes, WynnBET consistently offered more competitive odds than SI Sportsbook across most sports and markets. Independent odds comparison tools placed WynnBET’s pricing alongside top-tier operators like DraftKings and BetMGM, while SI Sportsbook’s odds were generally average for the market. The difference was most noticeable in NFL and NBA point spread markets where WynnBET typically offered tighter juice and better value for bettors.

What states was WynnBET available in?

At its peak, WynnBET was available for online sports betting in nine states: Arizona, Colorado, Indiana, Louisiana, Massachusetts, Michigan, New Jersey, Tennessee, and Virginia. As of April 2026, only Michigan remains active for online operations. Nevada maintains retail sportsbook presence through Wynn Resorts properties. All other state licenses have been surrendered or allowed to lapse following the August 2023 withdrawal announcement.

Is there a WynnBET loyalty or VIP program?

WynnBET integrates with Wynn Rewards, the loyalty program of Wynn Resorts. This program allows online sports betting and casino activity to earn points that can be redeemed at Wynn and Encore resort properties in Las Vegas and elsewhere. High-volume bettors can access VIP-tier benefits including dedicated account managers, faster withdrawals, and personalized promotional offers. SI Sportsbook did not offer any comparable loyalty or VIP program during its operational period.

Responsible Gambling Resources

Whether you are a current WynnBET customer in Michigan, a former user of either platform, or evaluating new sportsbooks, responsible gambling practices should always be a priority. Sports betting is a form of entertainment and should never be treated as a source of income or a way to recover financial losses. Both WynnBET and SI Sportsbook offered responsible gambling tools during their operational periods, and all legitimate US sportsbooks are required by state gaming commissions to provide these protections to their customers.

WynnBET currently offers the following responsible gambling features for its Michigan customers: deposit limits (daily, weekly, and monthly), wager limits, loss limits, session time limits with reality check notifications, cooling-off periods of 72 hours to 30 days, and permanent self-exclusion. These tools can be accessed through the account settings section of the mobile app or website. Customers who feel they may have a gambling problem should take advantage of these tools immediately rather than waiting for problems to escalate. Setting deposit limits proactively, before any problem develops, is one of the most effective protective measures available to sports bettors.

In the United States, sports betting regulation is handled at the state level by individual State Gaming Commissions, with responsible gambling advocacy provided nationally by the National Council on Problem Gambling (NCPG). The NCPG operates the national helpline at 1-800-522-4700, available 24 hours a day, 7 days a week, with trained counselors who can provide immediate assistance, referrals, and information about problem gambling treatment resources. You can also reach NCPG via text (text HOME to 233121) or through their website at ncpgambling.org. Many states also operate their own responsible gambling programs and helplines specific to local resources and treatment providers. All users must be 21 years or older to place sports bets online in the United States. If gambling is no longer fun, stop immediately and seek help. Support is available, free, and entirely confidential.
