MLB Star Ronald Acuna Jr. Signs Prediction Market Deal, Raising Questions for Video Poker Operators

Atlanta Braves outfielder Ronald Acuna Jr. has signed an advertising partnership with Kalshi, becoming the first active Major League Baseball player to endorse a prediction market platform. The deal, announced during Game 4 of the Braves playoff series against the Los Angeles Dodgers, signals a new frontier in athlete-brand relationships that sits in a regulatory gray area between sports betting and financial markets.

For video poker operators and casino industry observers, the Acuna-Kalshi agreement matters because it tests the boundaries of how gambling-adjacent products interact with professional sports. If prediction markets gain mainstream acceptance through athlete endorsements, the regulatory landscape for all gaming verticals, including video poker, could shift.

Key facts

The advertisement debuted Wednesday during the Braves 4-1 loss to the Dodgers, which ended Atlanta’s postseason. In the commercial, Acuna climbs out of an underground space beneath home plate and jokes, “There’s no place like under home plate, because I live here.” Kalshi has not disclosed financial terms or confirmed whether Acuna will appear in additional campaigns.

Baseball trading volume on Kalshi has grown 36-fold year over year, according to the company. The platform already has agreements with seven MLB teams, including the Atlanta Braves, Boston Red Sox, Los Angeles Dodgers, San Diego Padres and San Francisco Giants. Rival Polymarket secured a deal with the New York Yankees, while Novig partnered with the New York Mets in July.

Regulatory uncertainty for prediction markets

The Acuna deal brings renewed attention to the unresolved regulatory status of prediction market operators. State gambling regulators argue that platforms like Kalshi need sports betting licenses to operate, while Kalshi maintains that federal oversight through the Commodity Futures Trading Commission covers its activities. This dispute has direct implications for video poker operators, who operate under state-level gaming commissions with clear licensing requirements.

MLB Commissioner Rob Manfred and the Major League Baseball Players Association previously warned players against trading contracts involving league-sanctioned events. The league’s position creates tension with the new advertising agreement, as Acuna promotes a platform that allows users to bet on baseball outcomes through event contracts.

Athlete endorsements and the gambling brand line

The Acuna deal places him alongside a growing group of athletes promoting prediction markets, including soccer star Lionel Messi, NBA forward Giannis Antetokounmpo and golfer Bryson DeChambeau. Polymarket has worked with LeBron James, Eli Manning and Derek Jeter.

This trend contrasts sharply with comments from San Antonio Spurs star Victor Wembanyama, who earlier this week ruled out ever promoting a sports betting company. Wembanyama drew a clear line between gambling brands and the companies he wants to represent, highlighting the reputational concerns that still surround sports wagering partnerships.

For video poker operators, the distinction matters. Video poker carries a different regulatory and public perception profile than sports betting or prediction markets. However, any expansion of gambling-adjacent products into mainstream sports could invite closer scrutiny from regulators and lawmakers who oversee all gaming verticals.

What this means for video poker operators

The Kalshi-Acuna deal is not directly about video poker, but it signals a broader trend: the normalization of event-based wagering through channels that bypass traditional state gambling frameworks. If prediction markets continue to grow through high-profile athlete endorsements, state regulators may respond by tightening rules across all gaming categories, including video poker.

Casino operators who offer video poker should watch how state gaming commissions react to the Kalshi model. Some states may seek to classify prediction market contracts as illegal sports wagering, which could lead to enforcement actions that reshape the competitive landscape. Others may create new licensing categories that blur the line between financial products and gambling.

Kalshi has also reportedly discussed a broader partnership with MLB, though no agreement has been announced. A league-level deal would represent a significant shift in how professional sports organizations engage with event-based wagering platforms.
