Genius Sports Partners Polymarket and Kalshi in Data Push
The sports data supplier enters prediction markets, squaring off against Sportradar for dominance.
Genius Sports has signed multi-year data partnerships with Polymarket and Kalshi, entering the fast-growing prediction markets sector, according to iGaming Business (published August 6, 2026).
Why It Matters
Prediction markets have shifted from niche curiosities to contested territory for major sports data suppliers. Genius Sports joining Polymarket and Kalshi signals that incumbent data providers view prediction markets as a durable revenue channel, not a regulatory footnote. The move puts Genius directly alongside Sportradar, which signed its own multi-year deals with the same two operators around the same period, creating a two-horse race for data dominance in this segment. For bettors and operators, more competition between data suppliers typically pressures pricing and raises data quality standards. As prediction markets attract regulatory scrutiny across multiple U.S. states, having credentialed data partners like Genius and Sportradar may also help Polymarket and Kalshi demonstrate market integrity to regulators.
Context
Polymarket and Kalshi are the two highest-profile prediction market platforms operating in the U.S., with Kalshi holding CFTC regulatory approval for event contracts and Polymarket serving a largely international user base. As of August 2026, both platforms have expanded their sports-related contract offerings significantly, creating demand for the same real-time data feeds that power traditional sportsbooks. Genius Sports built its business supplying official league data to licensed bookmakers — a model that translates directly into prediction market applications.
What's Next
The immediate test is whether Genius's official data integrations give Polymarket and Kalshi a competitive settlement-accuracy edge over prediction markets relying on public data sources. Watch for additional league-level data rights announcements tied to these partnerships in the months ahead.
