Kalshi-Catalist Sports Partnership Announcement Disappears Hours After Reveal

This past week, on the morning of Tuesday, August 18, a multi-year agreement between Kalshi and Catalist Sports was announced. The deal includes official data rights as well as live streaming. While it was announced and seemingly in place, a few hours later that same morning, the announcement from Catalist was yanked off their site. 

As of August 22, there's no update regarding whether this partnership will continue or if it's been axed. 

Kalshi-Catalist Deal Included Live Sports Streaming

This deal with Kalshi and Catalist Sports would've seemingly included live streams of tennis and soccer. With this deal, users at Kalshi would've been able to watch more than 65,000 tennis matches per year, including the Davis Cup, Australian Open, and World Tennis Tour. As for soccer, it would've included two prominent leagues: Ligue 1 and Serie A. 

In addition to soccer and tennis, Catalist Sports is also growing its basketball and hockey offerings. The main selling point of the soccer live stream was fans in the United States, fresh off the 2026 World Cup. 

This comes after Polymarket, a competing prediction market platform, signed a deal with Genius Sports for not only official data but also live streaming. Kalshi also signed a deal with Genius Sports, but that was only mentioned for official data. 

Under that deal with Genius, they'll be providing Kalshi with the "highest quality, real-time data across its full soccer portfolio. This includes the English Premier League, Serie A, Liga MX, Argentine Primera División, French Ligue 1 and more."

Kalshi Has Had Other Partnership Confusion

Kalshi had another recent snafu involving an agreement. During the 2026 World Cup, Kalshi posted a claim to be the official World Cup partner, but FIFA had already announced ADI Predictstreet as the partner. 

Also, in 2025, Kalshi reneged on a deal with xAI, Elon Musk's AI company, hours after the deal was announced. 

That, paired with Catalist Sports' live streaming, would've been a nice pairing. 

Now, we'll wait to see if this deal goes through. August 25 will mark one week since the announcement was posted and then taken down.
