Prediction platform Kalshi signs sponsorship pacts with five MLB clubs, explores league-wide deal
Kalshi announced multi-year brand partnerships with the Atlanta Braves, Boston Red Sox, Los Angeles Dodgers, San Diego Padres, and San Francisco Giants. The agreements include stadium advertising, digital promotions, and branded spaces, such as naming rights for a bar at Dodger Stadium. The company is also in talks with Major League Baseball for a separate league-level partnership.
The five-team slate gives Kalshi visibility across several of baseball's largest media markets, with the Dodgers arrangement including naming rights to a stadium bar. The platform's baseball trading volume has grown dramatically, rising from roughly $355 million in early 2025 to nearly $13 billion during the same stretch this year.
Kalshi is also pursuing a league-wide agreement with MLB, though financial terms remain undisclosed. Rival platforms have made comparable moves — Polymarket with the Yankees and Novig with the Mets — while MLB and the CFTC established an information-sharing memorandum in March. The broader prediction-market industry has expanded into soccer, hockey, and mixed martial arts.
The growing integration of prediction markets into professional sports could normalize wagering on events beyond game outcomes, potentially reshaping how fans engage with teams and how leagues oversee
