At a time when fast-growing prediction markets are jostling for tie-ups with big name sports franchises, Kalshi announced deals with five of Major League Baseball’s best known franchises. On Tuesday, the site announced it has arranged multi-year brand partnerships with The Atlanta Braves, Boston Red Sox, Los Angeles Dodgers, San Diego Padres, and San Francisco Giants.
The partnerships will let the prediction market platform advertise through stadium ads, digital and radio promotions, and branded spaces. For example, the Dodgers will give Kalshi naming rights for the Golden Glove Bar under the partnership. The platform will also offer fans special promotions and in-person events at the teams’ home ballparks.
The announcement comes as major prediction markets race to partner with Major League Baseball teams. These markets, which allow traders to wager on anything from sports to elections and pop culture, have exploded over the past two years. Sports make up a significant portion of trading. So far in 2026, baseball-related contracts traded on the platform totaled nearly 13 billion, according to a Kalshi spokesperson. The figure represents a 36-fold increase from the roughly 355 million contracts traded during the same period in 2025.
