An Independent Integrity Body Found 7 Betting Irregularities at the World Cup. FIFA Said There Were None. The Clash Centres on Polymarket.
The Group of Copenhagen — the Council of Europe's independent match manipulation watchdog — raised seven yellow notices for potential betting irregularities during the 2026 World Cup, directly contradicting FIFA's all-clear published on Tuesday. The most troubling finding involves Polymarket: the platform opened a market on 2 July asking whether Folarin Balogun would play against Belgium — the same day Balogun received a red card, three days before FIFA publicly confirmed his ban was suspended. No equivalent markets were opened for any of the other 14 red cards at the tournament.
The Group of Copenhagen, the Council of Europe's independent match integrity watchdog operating under the Macolin Convention, raised seven yellow-category notices for potential betting irregularities across the 2026 World Cup's 104 matches. The findings, summarised Wednesday by the Council of Europe, directly contradict FIFA's own Integrity Task Force, which published an all-clear on Tuesday stating it had found 'no suspicious betting activity or indications of match manipulation in connection with any fixture.' The clash between a FIFA-affiliated body and an independent one is the sharpest integrity dispute to emerge from any World Cup in recent history.
The most substantive individual finding involves Polymarket. The platform opened a market on 2 July asking 'Will Folarin Balogun play against Belgium?' — the same day the American striker received a red card against Bosnia and Herzegovina. Under normal FIFA rules, a red card triggers an automatic one-match suspension. FIFA's Disciplinary Committee only confirmed Balogun's ban had been suspended — making him eligible — on 5 July, three days later. The report notes that no comparable market was opened for any of the other 14 players shown red cards during the tournament. Polymarket opened that one market, on that one player, on the day of the incident, before the ruling was public. The Group of Copenhagen has sent an official written request to FIFA for an explanation.
A second prediction-market finding involves a $4.8 million position on Polymarket backing Spain not to defeat Cape Verde in a group stage match — a game that ended 0-0. Spain were heavy favourites. Gambling industry expert Christian Kalb cautioned against reading too much into it: 'If you are a traditional bookmaker, there will be matches when everyone bets on a very strong favourite to win. They could use a prediction market like Polymarket to hedge that risk.' Yellow notices per the Group's framework can reflect many things — unexplained odds movements, rumours, or legitimate hedging. They do not indicate confirmed manipulation.
The Group of Copenhagen's operation was the first time any international integrity body has continuously monitored prediction markets — Polymarket and Kalshi (an official FIFA partner) — at a major tournament. Its report states that prediction markets 'raise unprecedented issues: they allow betting on a very wide range of events, often anonymously and using payment methods that are difficult to trace.' The $240 billion in total bets across the tournament — roughly twice the 2022 Qatar figure — reflects how quickly prediction market volume has scaled the integrity challenge. For UK readers, the Macolin Convention is a Council of Europe treaty to which the UK is a signatory; the Group of Copenhagen's work feeds directly into the regulatory frameworks that inform the Gambling Commission's approach to new betting products.
