Polymarket has partnered exclusively with OneFootball to reach 645 million fans ahead of the World Cup.

According to Mars Finance, Polymarket announced on Thursday an exclusive partnership agreement with Berlin-based digital football platform OneFootball. Approximately two weeks before the start of the 2026 FIFA World Cup, Polymarket will integrate its prediction market with OneFootball's 200 million monthly active users and 645 million fan ecosystem. Polymarket will become the sole prediction market partner within the OneFootball app, barring competitors such as Kalshi from accessing the product. This is Polymarket's seventh major football partnership this year and its first with a media app distribution channel, following previous agreements with MLS, LaLiga, Serie A, Lazio, and DAZN. According to Pew Research Center analysis, sports have accounted for 39% of Polymarket's total transaction volume since July 2024. The 2026 World Cup champions market has accumulated over $1.2 billion in transactions since its launch last July, while the broader World Cup category market totals approximately $1.3 billion. OneFootball previously launched BALLS, an OFC token and points system based on Base and Ethereum. The integration with Polymarket will translate user participation into actual transactions. OneFootball has raised over $300 million in funding, with investors including Liberty City Ventures, Animoca Brands, and Adidas.
