Genius Sports signed data partnership agreements with Polymarket on Aug. 4 and Kalshi on Aug. 5, supplying real-time official soccer data and integrity services to both prediction-market platforms. The company announced the deals after reporting second-quarter revenue up 65% to $195.5 million on Aug. 6, with an incremental contribution from prediction markets booked before either partnership was finalized. Chief executive Mark Locke said demand is rising as prediction-market operators enter the sector, and Genius positions itself as the owner of official data that regulated ecosystems depend on and the audience layer on top of it.
Kalshi Partnership Covers Real-Time Soccer Data and Marketing Services
Genius Sports will supply Kalshi with real-time official data across its full soccer portfolio, including the English Premier League, Serie A, Liga MX, the Argentine Primera División, and French Ligue 1, under an agreement announced Aug. 5. Kalshi will use the verified feeds as a single source of truth for settling sports event contracts, join Genius's information-sharing processes, restrict certain market types, and take marketing services through Genius's Legend-owned media properties. Adam Barrick, head of sports partnerships at Kalshi, said the use of official data and integrity services is more important than ever as the prediction market ecosystem continues to expand at a rapid pace. The release names no start date, and neither company disclosed financial terms.
Polymarket Deal Adds Exclusive U.S. Livestreaming Rights
The Polymarket agreement, announced Aug. 4, covers the same settlement data and integrity services but adds exclusive U.S. livestreaming rights and league intellectual property across selected competitions, including Serie A. The deal took effect immediately for eligible U.S. users. Neither company disclosed financial terms. Both platforms also worked with Genius during the World Cup, when it supplied official data for Kalshi's Argentine Football Association partnership and supported Polymarket's Liga MX sponsorship in the U.S. This week's deals convert those single-property arrangements into platform-level relationships.
Genius Sports Reports Q2 Revenue of $195.5 Million and $76.7 Million Net Loss
Genius reported second-quarter results on Aug. 6: revenue up 65% to $195.5 million against $185 million of guidance, adjusted EBITDA up 54% to $52.6 million against $45 million guided, and a group adjusted EBITDA margin of 26.9%, 258 basis points above the margin implied by guidance. The company attributed that beat to early Legend synergies, execution in media, and an incremental contribution from prediction markets. Because both partnerships were announced after the June 30 quarter end, neither produced that contribution. Genius raised full-year revenue guidance to $1.005 billion to $1.025 billion and adjusted EBITDA to $285 million to $295 million. Net loss widened to $76.7 million from $53.9 million, attributed largely to costs tied to Legend, and the half-year loss reached $132.2 million. Media technology revenue, the division Legend sits in, rose 192.8% to $78.2 million with only two months of contribution; betting technology rose 27.5% to $117.4 million on renewal pricing and expanded services. Genius closed the Legend acquisition on May 1 in a transaction valued at up to $1.2 billion. Genius shares rose 14.3% on Tuesday following the Polymarket news and added roughly 2% more on Wednesday after the Kalshi deal, closing at $8.33, up almost 25% on the week.
July Combined Volume Reaches $50.59 Billion Across Three Platforms
The Block's dashboard puts July combined volume across Kalshi, Polymarket, and Polymarket US at a record $50.59 billion, up 7.8% from a June baseline the dashboard has since revised upward to $46.95 billion. Kalshi accounted for $37.7 billion of it. Trading volume does not equal the total money staked — contracts are resold repeatedly, so the figure overstates funds at risk. Open interest across the three venues fell from about $2 billion at the start of July to $1.2 billion by month's end, after the July 19 final. Polymarket's international platform fell 26% to $7.9 billion even as its U.S. arm rose 54% to $5 billion. On Aug. 4, a federal judge granted Utah summary judgment against Kalshi, rejecting every preemption theory the exchange raised over its sports event contracts, a decision it is appealing to the Tenth Circuit.
