Sportradar says Polymarket and Kalshi deals fuel 19% revenue growth
Sportradar reported 19% year-on-year revenue growth to €378 million for Q2 2026. The sports data and technology provider attributed part of the increase to agreements with Polymarket and Kalshi. Executives told analysts on the August 4 earnings call that they expect prediction markets to deliver tens of millions of dollars in revenue this year. The company did not provide specific contribution figures from either platform.
Sportradar's public emphasis on prediction markets signals that data suppliers now view event contracts as a durable revenue layer, not a speculative sideline. The tens-of-millions forecast puts pressure on rival data providers to match or cede the vertical. For Polymarket and Kalshi, the partnership grants legitimacy and infrastructure scale, but it also deepens dependence on a single data pipe that serves competing platforms.
Kalshi faces the sharper squeeze: Robinhood is already in talks with Crypto.com for prediction market contracts, eroding Kalshi's pricing power as a default supplier. Sportradar's data becomes table stakes; the competitive edge shifts from who has the feed to who can extract the best economics from brokers and market makers. The platform that locks in Sportradar on exclusive terms would gain a short-term moat; shared access turns the data into a commodity cost.
