Kalshi Incorrectly Claimed Deals With Giants, Braves Were Exclusive

Kalshi had described the deals it announced with five MLB teams on Tuesday as all being "exclusive," but this is not entirely accurate, according to sources who spoke with Front Office Sports (FOS). While the press release initially referred to all the deals as "exclusive, multi-year brand partnerships," at least two of the agreements—those with the Braves and Giants—are not exclusive, the sources added.

The Giants' deal is not exclusive, as confirmed by a team representative. Both the Dodgers and Red Sox deals are exclusive, as stated in the teams' press releases. The exclusivity of the Padres agreement remains unclear, with a representative for the team not immediately responding to FOS's request for comment. Kalshi's spokesperson clarified that the error was unintentional and that the company has amended its press release.

Individual press releases correcting the information were also issued to local media on Tuesday. Some of the deals are not guaranteed to last multiple years, as they include mutual opt-out clauses that allow either side to terminate the contract in October. The deals announced on Tuesday marked Kalshi's first team-level agreements in MLB, although the company already has a team deal with the Blackhawks through its partnership with Polymarket.

Polymarket secured the overall agreement with MLB in March, an arrangement valued at up to $300 million over four years. This deal made Polymarket the exclusive prediction-market partner for the league, but individual teams can still enter into their own agreements. MLB has designated other entities as authorized prediction-market platforms under its integrity framework, including Kalshi and Novig.

Novig was the first platform to establish a team-level deal with the Mets, which is exclusive and multi-year. Polymarket recently reached an agreement with the Yankees, which is currently valid only for the remainder of the season. As of Tuesday, there are seven individual MLB teams with prediction-market partnerships, accounting for nearly one-quarter of the league.

FOS contacted all MLB teams on Tuesday to inquire about any prediction-market agreements they may have; representatives from the Guardians, Nationals, Phillies, Rockies, and Angels confirmed they do not have such partnerships. Kalshi's sports-event contracts are currently involved in numerous lawsuits across the U.S. court system, with several states arguing that these contracts should be treated similarly to traditional sports betting, which is regulated by individual states.
