Genius Sports has signed partnerships with Polymarket and Kalshi to supply official live match data, integrity monitoring and exclusive streaming to the US prediction markets. Both deals are live.
The Polymarket agreement covers live data feeds, Serie A streaming for US users, and marketing support through Legend, the media network Genius acquired for $1.2 billion this summer. Streams will be tied to live event contracts to keep users inside the product. Polymarket also gains tools to flag unusual trading activity, while leagues get access to market data. Kalshi's deal is broader: Premier League, Serie A, Liga MX, the Argentine Primera División and Ligue 1, plus marketing, media and participation in integrity information-sharing systems.
Sportradar closed similar deals with both operators in June. On a quarterly call, Sportradar CEO Carsten Koerl described prediction markets as a natural extension: new states, new audience, higher engagement.
For Genius this is the first move into prediction markets. The company is bundling official data, streaming, integrity infrastructure and media reach through Legend as a trust and differentiation play in a growing segment.
