Genius signed deals with both Polymarket and Kalshi in August, to provide real-time event data and league integrity services, as well as streaming services. Fellow data provider Sportradar also announced similar multi-year partnerships with both Kalshi and Polymarket in June.
Initial reaction from investors was largely unfavourable. Genius shares plunged 13% on 18 Sept., falling 17% for the week. The data provider closed the session at $5.64 per share, well below the $6.19 price when it announced the Legend acquisition in February.

James Monk, founder of sports data and streaming provider Catalist Sports, has witnessed that dependence directly. Catalist supplies ITF tennis data to Kalshi and Polymarket and has an exclusive US sports-streaming agreement with Kalshi.
The company must also provide data to the firms making markets on those events.
