Key Takeaways
- Kalshi signs multi-year sponsorship agreements with five MLB teams.
- Baseball trading volume on Kalshi increased 36 times over the last year, with over 500 active markets.
- Polymarket, a competitor of Kalshi, also sponsors the MLB and has secured deals with MLS and UFC.
- Kalshi faces legal challenges over the classification of its sports contracts as betting according to authorities in Connecticut and New York.
Kalshi has closed multi-year sponsorship agreements with five prominent Major League Baseball (MLB) teams: Atlanta Braves, Boston Red Sox, Los Angeles Dodgers, San Diego Padres, and San Francisco Giants. This was reported by the New York-based platform on Tuesday, August 25, emphasizing its sustained bet on professional American sports.
Agreement Dynamics and Kalshi's Presence in Baseball
The news marks the latest step in Kalshi's sports sponsorship strategy. According to the company, the trading volume related to baseball on its prediction market has increased 36 times in the last year. Currently, Kalshi has more than 500 active real-time baseball markets, covering "prop bet" markets on home runs, strikeouts, or stolen bases. For the World Series winner, the total traded approaches $60 million.
Adam Barrick, head of sports partnerships at Kalshi, explained:
"The idea is that fans are already interacting with their favorite teams on Kalshi, so it makes sense to extend that connection with some of the most beloved teams in American baseball," Barrick stated.
Context of Rivalry and Sports Partnerships in the U.S.
Kalshi's expansion strategy is not limited to MLB. Among recent agreements, the company also highlights partnerships with the Chicago Blackhawks ice hockey franchise (NHL) and an agreement with Madison Square Garden Entertainment Corp., the owner of the namesake venue. Meanwhile, MLB itself is sponsored by Polymarket, a direct competitor of Kalshi, after reaching an agreement in March accompanied by an information exchange agreement with the Commodity Futures Trading Commission.
In the last year, Polymarket has also secured sponsorship contracts with Major League Soccer (MLS) and the Ultimate Fighting Championship (UFC).
Media Diversification and Exploration of New Channels
This week, Front Office Sports revealed that The Athletic is in talks to be sponsored by Kalshi. In fact, some content from The Athletic already featured Kalshi branding during the football World Cup. The sports portal, owned by The New York Times, had previously worked with BetMGM on advertising deals.
Regulatory Implications and Legal Context for Prediction Markets
Kalshi's current growth in the sports sector contrasts with significant legal challenges. In early August, the platform faced two legal setbacks: a judge in Connecticut denied an injunction, and the Attorney General of New York filed a $36 billion lawsuit against the company. Authorities argue that sports event contracts constitute gambling, a view rejected by Kalshi, which insists on defining itself as a trading platform rather than a betting platform.
Kalshi Facing Competition and the Regulatory Framework
The competition between Kalshi and Polymarket heightens the visibility of prediction markets in American sports. The differing regulatory stances and agreements with key leagues such as MLB, MLS, UFC, and NHL showcase a rapidly transforming sector, driven both by fan demand and the adaptation of major platforms to state and federal legal frameworks. Operators and suppliers in the industry must monitor these moves considering their commercial and regulatory impact.
To follow the development of sports markets and the news in the B2B sector, it is advisable to keep an eye on both regulatory decisions in the United States and future alliances between platforms and sports entities.
