Kalshi is widening its footprint in Major League Baseball (MLB) after agreeing to exclusive, multi-year brand partnerships with five clubs. The prediction market platform announced the deals on Tuesday (August 25).

The Atlanta Braves, Boston Red Sox, Los Angeles Dodgers, San Diego Padres and San Francisco Giants are all part of the agreements. Kalshi will serve as a prediction market partner for each team, with its brand appearing in stadiums and across social media, digital promotions and radio. Fans will also see activities and offers tied directly to the platform.

The expansion comes as baseball trading has surged on Kalshi. The company says trading volume connected with the sport is now 36 times higher than it was one year earlier.

Kalshi and MLB push comes as prediction markets gain wider acceptance

At Dodger Stadium, the partnership will give Kalshi a particularly visible presence. LED signs carrying its branding will be displayed around the ballpark, while the company is also getting naming rights for the stadium’s Gold Glove Bar.

Dodgers fans can expect Kalshi-specific offers as well. During the season, the agreement will bring exclusive fan activities to Centerfield Plaza.

“The idea is that fans are already engaging with their favorite teams on Kalshi, so it only makes sense to extend that fandom to some of the most beloved baseball teams in America,” said Adam Barrick, Head of Sports Partnerships at Kalshi.

The agreements arrive during a shift in MLB’s relationship with prediction markets. In July, the New York Mets announced a multi-year partnership with Novig that the companies described as the first deal between an MLB franchise and a prediction market company.

At league level, MLB has already chosen Polymarket as its exclusive prediction market exchange partner. MLB and the US Commodity Futures Trading Commission also signed a memorandum of understanding in March covering information sharing, market monitoring and efforts to spot fraud or manipulation involving baseball event contracts.

The growing commercial involvement comes with restrictions for people inside the sport. During the 2025 season, MLB circulated guidance telling major and minor league players not to participate in baseball-related prediction market contracts, including products offered by Kalshi and Polymarket. The league treated that activity as prohibited under its long-standing betting rules.

Kalshi, founded in 2018, runs an exchange where customers trade contracts based on event outcomes. The company presents prediction markets as a way of showing changing expectations about future events in real time.
