Kalshi announces multi-year marketing partnerships with five Major League Baseball teams, expanding its presence in the sport. The company ties up with the Los Angeles Dodgers and three other National League teams, and also reaches an agreement with the Boston Red Sox, according to the reports.

The deal builds on Kalshi’s broader effort to grow in the prediction-markets space as trading activity around sports continues to rise. Several outlets describe the agreements as exclusive brand partnerships rather than trading expansions within MLB itself, and note that the partnerships strengthen Kalshi’s visibility across MLB’s fan base.

One outlet also adds context that the teams involved are located in states where traditional sports betting is prohibited or where sports wagering has faced legal challenges, framing the partnerships as another way for Kalshi to engage with MLB audiences amid an uneven betting landscape. Other coverage focuses more on the scale and marketing footprint of the agreements. Overall, the reports agree on the number of teams, the multi-year nature, and Kalshi’s stated interest in pursuing further partnership opportunities, including separate league-level discussions.
