Genius Sports has launched Prediction.com, a consumer platform that compares event contracts and prices across multiple prediction markets. The service went live on Sept. 17 through Legend, the sports and gaming media business Genius acquired earlier this year, covering sports, politics, entertainment, economics, and crypto.
Users can compare prices for equivalent contracts across different exchanges instead of opening each platform separately. Current listings pull from Kalshi, Polymarket and Polymarket US, Novig, ProphetX, PredictIt, and Predict.fun, depending on the event. Anyone who decides to trade gets sent to the relevant exchange, which leaves Prediction.com as a discovery and comparison service rather than an exchange offering contracts of its own.
Genius has also built a cross-platform comparison engine for multi-leg contracts, so users can see how the same combination is priced at different venues. Sports combos offered through platforms including Novig show up there now, alongside an arbitrage scanner, a feed tracking trades from successful users, a paper-trading simulator, and prediction-market APIs. Sign-up offers from several operators get promoted separately on the site.
Sports markets come with Genius’ live game data next to real-time contract prices, so users can follow play-by-play events and shifting market probabilities on one page. Genius already holds official data rights across a large portfolio of competitions, major football leagues included, and sells that information to sportsbooks, broadcasters, and prediction-market operators.
Separate prediction-market agreements with Polymarket and Kalshi came in August. Polymarket gets official data, integrity services, and selected live sports streaming, Serie A coverage in the US among it, while Kalshi gets official data across the Genius football portfolio plus media, marketing, and integrity services. Prediction.com now puts Genius on the consumer side too, comparing products from companies that buy its data and media services.
Legend joined Genius Sports on May 1, when the company completed an acquisition valued at up to $1.2 billion, $900 million of it payable at closing with up to $300 million more in earnout payments. Legend owns sports and gambling media properties including Covers.com, Casino.org, and Casino Guru, and recorded 320 million visits from 118 million unique users during 2025. Prediction.com runs on the comparison and consumer technology already built across that business.
The acquisition also handed Genius a much larger direct audience alongside its existing B2B sports-data operation. Genius said at closing that it wanted to combine official sports information with media and advertising products, and its 2026 outlook put annualized pro forma revenue for the combined business at around $1.1 billion with adjusted EBITDA between $320 million and $330 million.
Prediction.com shows how that works around event contracts. Someone following a football game can compare prices across several platforms, watch live data supplied by Genius, and then go straight to whichever exchange has the contract they want. The site also covers non-sports markets where Genius doesn’t provide the underlying event data, which pushes Legend’s comparison business past conventional sportsbook odds.
Genius hasn’t disclosed revenue targets for Prediction.com or named every platform due to be integrated. The company said it plans to expand coverage, functionality, and partner integrations as the prediction-market sector grows, which adds another business next to the data, streaming, integrity, and marketing services it already sells to Kalshi, Polymarket, and others.
