Kalshi Taps Sportradar for Official League Data and Integrity Tools in Prediction Markets

Kalshi has signed a multi-year global deal making sports-data company Sportradar its official data and integrity provider, giving the prediction market official league feeds and surveillance tools as it fights state efforts to brand its contracts illegal betting.

• • Kalshi named Sportradar its official data and odds provider across MLB, NHL, MLS and the UFC.
• • Kalshi gains two Sportradar integrity tools (UFDS AI and the Integrity Exchange) to flag suspicious trades.
• • About 11 states have moved against Kalshi’s sports contracts as illegal betting, while the CFTC backs it.

Official data, and an integrity shield

The agreement gives Kalshi official data and live odds across Major League Baseball, the NHL, MLS and the UFC, which Sportradar says will power pre-game and in-play markets while ensuring timely settlements. For Kalshi, official feeds mean it can resolve contracts faster and more accurately than unofficial data allows. Beyond the data, the package bundles fan-engagement content and customer-acquisition marketing aimed at high-value sports fans, the same commercial toolkit Sportradar sells to bookmakers. CEO Tarek Mansour said the platform would use the league data for quicker trade settlements and a better customer experience.

Kalshi also picks up Sportradar’s integrity stack: its UFDS AI system, which detects suspicious betting behavior, and the Sportradar Integrity Exchange, a secure network for sharing manipulation threats. Mansour cast the monitoring as a measure to protect users, a notable emphasis for a sector dogged by insider-trading concerns.

Roughly a dozen state regulators have moved against prediction markets, while Senate Democrats recently argued that event contracts amount to an unlicensed form of sports betting, even as the CFTC asserts federal authority over them. Sports outcomes drive most of Kalshi’s trading-fee revenue, making the data-and-integrity question central to its business. An official-data-and-integrity partnership lets Kalshi present itself as a surveilled, league-backed venue rather than the unregulated betting operation its critics describe.

The deal also puts Kalshi on the same data backbone Sportradar supplies to sportsbooks like Draftkings and Flutter and to leagues including the NHL and MLB. Sportradar, which had signaled a move into prediction markets for months, called the agreement an initial step and said it could now contract directly with Kalshi’s brokers and market makers. The leagues whose data underpins these markets are themselves split: the NHL and MLB have struck their own prediction-market deals, even as a coalition of player unions has asked the CFTC to ban the riskiest categories of sports contracts.

For Kalshi, founded in 2018 and now the dominant US prediction venue, the partnership is as much about credibility as data, a bid to look like regulated financial infrastructure at the moment courts and statehouses are deciding whether it is one
