Genius Sports Signs Official Data and Integrity Deal With Kalshi

Genius Sports (GENI ) will supply official league data, marketing and integrity services to Kalshi under a partnership announced August 5, 2026, tying the prediction market’s sports-contract settlement to the same real-time data feeds that power licensed sportsbooks. The agreement covers Genius Sports’ full soccer portfolio, including the English Premier League, Serie A, Liga MX, the Argentine Primera División and French Ligue 1.

The data will be used as the source of truth for settling sports prediction market contracts, replacing the unofficial or delayed feeds that markets have historically leaned on. Kalshi will also join Genius Sports’ integrity information-sharing processes, which restrict certain market types and give professional leagues greater visibility into trading activity tied to their competitions. On the commercial side, Genius Sports will run marketing services for Kalshi through the media properties it picked up in the Legend acquisition.

“As the prediction market ecosystem continues to expand at a rapid pace, the use of official data and integrity services is more important than ever,” said Adam Barrick, Kalshi’s head of sports partnerships, in the announcement.

Kalshi now buys data from both of the industry’s official suppliers

The Genius Sports deal lands less than two months after Sportradar announced its own agreement with Kalshi on June 8, 2026, a global deal positioning the Swiss firm as a core data and solutions provider across premier sports leagues. Where the Sportradar agreement made it a core data and solutions provider across premier sports leagues, the Genius Sports deal plugs in the soccer portfolio and folds Kalshi into a second integrity network.

Kalshi had already tested the model around the World Cup. On June 10, 2026, it signed an official sponsorship with the Argentine Football Association, under which Genius Sports, the AFA’s data and streaming partner, supplied official data for creating and settling World Cup-related contracts. The new agreement turns that single-tournament arrangement into a standing deal across competitions.

Genius Sports has been building both sides of the prediction-market fence at once. Earlier this month it struck a streaming and data deal with Polymarket, Kalshi’s main rival, and in June it attached official data and integrity collaboration to Liga MX’s US sponsorship agreement with Polymarket. The company, whose partners include the NFL, the NCAA, DraftKings (DKNG ) and bet365, is positioning itself as the settlement layer for the category regardless of which exchange wins.

Official data arrives as regulators close in on sports event contracts

The integrity provisions are doing quiet work in this deal. Kalshi’s sports markets have drawn enforcement pressure at the state level all summer: a Washington judge found the platform likely qualifies as an illegal gambling site under state law, Nevada forced it to geofence its sports markets, and state lawmakers have been moving to put prediction markets on notice over gambling statutes.

Verified league data with information-sharing attached gives Kalshi an answer to one of the sharpest questions in that fight: who is watching these markets for manipulation, and on whose numbers do contracts settle. Both data giants now supplying the exchange built their businesses doing exactly that for regulated sportsbooks, and both have now extended the same plumbing into prediction markets.
