Kalshi is adding live sports directly to its prediction market experience through a new multi-year partnership with Catalist Sports. The deal gives Kalshi exclusive U.S. prediction market access to Catalist Sports' live streaming portfolio, along with official low-latency data covering thousands of sporting events.
For users, the idea is simple: watch an event and trade on it without bouncing between platforms. The partnership is Catalist Sports' first agreement of its kind with a regulated prediction market. It also marks Kalshi's first partnership with a sports streaming provider, another notable step in the platform's growing push into live sports.
Tennis Gets a Major Upgrade on Kalshi
Tennis is easily one of the biggest pieces of the agreement. Catalist Sports will provide official streaming and low-latency data covering more than 65,000 tennis matches annually, including the World Tennis Tour. Kalshi will also receive official data connected to major competitions including the Australian Open and Davis Cup.
That volume could make tennis particularly interesting for live prediction markets. Matches happen throughout the day worldwide, giving users a nearly constant stream of events to follow. Low-latency official data also helps Kalshi create and settle markets using information coming directly from trusted competition sources.
The Deal Goes Well Beyond Tennis
Catalist Sports brings considerably more than tennis to the table. Kalshi will gain streaming access to international soccer properties including France's Ligue 1 and Brazil's Serie A, plus content involving basketball and ice hockey competitions. That gives the platform another way to capitalize on sports interest following this summer's FIFA World Cup.
Some of the biggest pieces of the partnership include:
- More than 65,000 tennis matches annually
- World Tennis Tour live streams and official data
- Australian Open and Davis Cup data
- Ligue 1 and Serie A content
- Additional basketball and ice hockey competitions
Specific launch dates were not announced, so you shouldn't expect every piece of the portfolio to suddenly appear at once. Still, the scale of the agreement makes clear that Kalshi sees live sports content as more than a small experiment.
Prediction Markets Want to Keep You on the Platform
The bigger story here may be what streaming does to the prediction market experience. Sports users already watch games while following scores, statistics, and market prices across multiple screens. Putting the live event directly alongside the market removes one more reason to leave the platform.
Polymarket has also moved in this direction with its ATP Tour streaming integration, suggesting live video could become another area where major prediction market operators compete. Official data partnerships have already become increasingly common across the industry. Exclusive streaming rights give platforms another way to differentiate themselves when the underlying sports markets can otherwise look similar.
Exclusive Rights Raise the Cost of Competing
The word "exclusive" matters here. Catalist Sports isn't simply supplying Kalshi with another data feed. The agreement gives Kalshi sole U.S. prediction market access to its live streaming portfolio. That could create an interesting challenge for smaller competitors.
If premium sports content becomes part of what users expect from prediction markets, companies may need to secure their own streaming and data partnerships rather than simply compete through market selection and pricing. Every exclusive agreement potentially takes another useful piece of content off the table.
The Trade Handle Prediction Markets Take
We think prediction markets are beginning to look less like simple exchanges and more like complete sports platforms. Kalshi doesn't just want you to open the app, make a trade, and leave. Adding live streams gives users another reason to stay throughout an event and continue following markets in real time.
The bigger question is whether streaming actually produces more trading activity. We don't have that answer yet, but Kalshi and Polymarket are clearly interested enough to invest in the concept. If these integrations work, exclusive sports media rights could quickly become another battleground in the prediction market arms race.
