Kalshi signs exclusive Catalist Sports streaming and data deal
Kalshi has signed a multi-year exclusive partnership with Catalist Sports for live streaming and low-latency data across thousands of tennis matches and other events. The deal, announced August 18, gives Kalshi sole U.S. prediction-market access to Catalist Sports' portfolio. Specific financial terms and launch timelines were not disclosed. Catalist Sports described the agreement as first-of-its-kind for regulated prediction markets.
Kalshi just answered Polymarket's ATP Tour streaming integration with its own video play, turning live sports viewing into a must-have feature for regulated prediction markets. The Genius Sports deals already erased data access as an edge for both platforms, so Catalist Sports video becomes the next layer they fight over. Kalshi now controls a streaming pipeline no rival can replicate for tennis and multi-sport content.
Smaller platforms like DraftKings and Novig face a harder choice: spend on exclusive media rights or concede the integrated watch-and-wager experience to the two leaders. The cost of entry for latecomers rises with each signed partnership. Kalshi nor Polymarket has proven streaming converts to trading volume, but neither can afford to let the other own the full fan journey alone. The next league or supplier that lands exclusive terms with either platform will confirm streaming as the standard infrastructure layer for regulated sports event contracts in the United States.
