The exclusive deal puts prediction markets in front of OneFootball’s 200 million monthly active users — and a wider 645-million-fan ecosystem — as Polymarket’s 2026 soccer-distribution stack reaches saturation ahead of the June kickoff.
Polymarket has signed an exclusive partnership with OneFootball, the Berlin-based digital football platform, opening a distribution channel to a user base that the company says reaches more than 645 million fans worldwide and 200 million monthly active users, roughly two weeks before the 2026 FIFA World Cup kicks off in North America.
The deal, announced by Polymarket on Thursday, makes the prediction-market exchange the sole such partner inside the OneFootball app and product surface. OneFootball reports 200 million monthly active users across its app, web, connected-TV app and video network, and counts a wider ecosystem reach of 645 million fans once social channels and external publishing partners are included, according to its company page.
The integration is Polymarket’s seventh major football-or-soccer deal of 2026 and the first that targets a media-app distribution partner rather than a league or broadcaster. Earlier this year Polymarket signed exclusive US prediction-market deals with Major League Soccer in January, LaLiga in April and Serie A on May 14, plus a $22 million-plus front-of-shirt sponsorship with Serie A club Lazio through 2028 and a broadcast-integration tie-up with DAZN.
The User-Acquisition Math
Sports has made up 39% of Polymarket’s total trading volume since July 2024, according to Pew Research Center analysis, and the World Cup is its single largest sports contract.
The 2026 FIFA World Cup winner market has aggregated more than $1.2 billion in cumulative trading volume since its July 2025 launch, with broader World Cup-category markets adding up to roughly $1.3 billion across more than 100 contracts. The OneFootball slot lands as that funnel reaches its peak inflow weeks of the four-year cycle.
OneFootball brings something the league deals do not: an existing in-app prediction primitive. The platform launched the OneFootball Club fan-engagement layer earlier this year, with its OFC token going live on Base and Ethereum on April 9, alongside a points system called BALLS that already rewards users for daily check-ins, match predictions and social activity. The Polymarket integration converts that engagement loop into a real-money exchange surface.
‘Exclusive’ Deal
In Polymarket’s recent league deals, “exclusive” has been geographically scoped — typically meaning the league won’t sign another prediction-market exchange to use its data or marks in a given region, usually the US. The OneFootball arrangement is exclusive at the distribution level instead: Kalshi and other prediction-market platforms won’t appear inside the OneFootball product. Polymarket is free to continue stacking league agreements; OneFootball is not free to plug in a competitor.
The Regulatory Backdrop
The deal lands in a turbulent stretch for the prediction-market category. A New York Times investigation reported by The Defiant on May 26 found that Commodity Futures Trading Commission officials who pushed scrutiny of prediction markets had been suspended. Ten days earlier, Polymarket opened a markets line on private-company valuations using Nasdaq Private Market data. The OneFootball slot extends the platform’s surface area on the consumer side just as its regulatory posture in Washington is being re-litigated.
OneFootball has raised more than $300 million across its funding rounds, with investors including Liberty City Ventures, Animoca Brands and Adidas, and counts more than 200 clubs, leagues and federations as content partners with distribution into 194 markets. The Polymarket integration is the first one to put a regulated US-style derivatives product in front of that audience at scale.
Whether the World Cup converts OneFootball’s reach figures into Polymarket trading accounts — and at what cost-per-acquisition — is the number the next quarter will produce.
