Genius Sports Launches Prediction.Com To Compare Event Contract Prices Across Prediction Markets

Genius Sports Limited (NYSE: GENI) on September 17 launched Prediction.com, a consumer platform that lets users discover prediction markets, compare equivalent event contracts across multiple venues and follow how market probabilities change during live events.

The London-based sports data company said the platform brings markets and pricing from major prediction platforms into one destination. It also includes what Genius described as a proprietary cross-venue, multi-leg pricing engine. It is designed for combination contracts, a segment the company called fast-growing.

Prediction.com does not execute trades. Users compare prices on the site and are directed to the venues to place positions.

At launch, the Prediction.com homepage displayed pricing from Kalshi, Polymarket (US and international), Novig, ProphetX, Underdog, PredictIt and Predict.fun. Market categories include sports, elections, politics, economics, entertainment and crypto.

For sports markets, the platform combines Genius Sports' live game data with real-time prediction market pricing. Its in-game view shows play-by-play action alongside changing probabilities, prices and market signals.

The site also offers an arbitrage scanner, a "Smart Money" feed that tracks trader activity, a paper trading simulator, featured combos and a picks section. A disclaimer on the page states that its content is "for informational and educational purposes only. Not financial advice."

Genius launched Prediction.com through Legend, its consumer media and technology business. Genius announced the acquisition of Legend on February 5, 2026, in a deal worth up to $1.2 billion. The terms were $800 million in cash and $100 million in Genius stock at closing, plus an earnout of up to $300 million tied to profitability and cash flow over two years. The transaction closed on May 1.

Legend's brands include Covers.com, Casino.org and Casino Guru. According to Genius, the network recorded 320 million visits from 118 million unique visitors in 2025.

Genius said Prediction.com builds on Legend's existing consumer and comparison technology and serves as a new flagship brand for the prediction market category.

Genius already supplies official sports data and integrity services to prediction market operators. On August 4, the company expanded its partnership with Polymarket to cover official data, exclusive live streaming of selected competitions including Serie A, integrity services and marketing through Legend's properties. A day later, it signed a similar agreement with Kalshi covering official data for competitions including the English Premier League, Serie A and Ligue 1, along with integrity and media services.
