An Independent Integrity Body Found 7 Betting Irregularities at the World Cup. FIFA Said There Were None. The Clash Centers 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, in direct contradiction to FIFA's own Integrity Task Force, which published an all-clear on Tuesday. The most troubling finding involves Polymarket: the platform opened a market on July 2 asking whether Folarin Balogun would play against Belgium — the same day Balogun received a red card and three days before FIFA publicly confirmed his ban was suspended. No equivalent markets were opened for any of the other 14 red cards shown at the tournament.
The Group of Copenhagen, an independent international network dedicated to detecting and preventing sports manipulation that operates under the Council of Europe's Macolin Convention, raised seven yellow-category notices for potential betting irregularities identified during the 2026 FIFA World Cup's 104 matches. The findings, summarized Wednesday by the Council of Europe, directly contradict FIFA's own Integrity Task Force, which published a statement on Tuesday saying it had found 'no suspicious betting activity or indications of match manipulation in connection with any fixture' across the entire tournament. The clash between the two bodies — one FIFA-affiliated, one independent — is the sharpest integrity dispute to emerge from any World Cup in the modern era.
The most substantive individual finding involves Polymarket. According to sources briefed on the report, Polymarket opened a market on July 2 asking 'Will Folarin Balogun play against Belgium?' — the same day the American striker received a red card against Bosnia and Herzegovina in the last-32 stage. Under normal FIFA rules, a red card triggers an automatic one-match suspension. FIFA's Disciplinary Committee confirmed that Balogun's ban had been suspended — meaning he would be eligible to play — only on July 5, three days later. The Group of Copenhagen's report notes that no comparable market asking whether a suspended player would be available was opened for any of the other 14 players shown red cards during the tournament. Polymarket opened that single market, on that single player, on the day of the incident, three days before the suspension ruling was public. The Group of Copenhagen has sent an official written request to FIFA for an explanation.
The second major 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 in a goalless draw. Spain were the prohibitive favorite. A position of that size on a heavy favorite to fail, which subsequently pays out, is the pattern integrity monitors look for: it either indicates prior knowledge of an outcome or, as gambling industry expert Christian Kalb explained to The Athletic, a large bookmaker using a prediction market to hedge its own exposure. 'If you are a traditional bookmaker, there will be matches when everyone bets on a very strong favourite to win,' Kalb said. 'So they could use a prediction market like Polymarket to hedge that risk — selling those outcomes against the possibility of a favourite winning to minimise potentially big losses.' Yellow notices, per the Group of Copenhagen's own framework, can reflect many things: unexplained odds fluctuations, social media rumors, or hedging activity. They do not indicate confirmed manipulation.
The Group of Copenhagen's operation was the first time any international integrity body has provided continuous real-time monitoring of prediction markets — both Polymarket and Kalshi, which served as an official FIFA partner during the tournament — at a major global competition. 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. Monitoring them is a first for an international competition.' The $240 billion in total bets placed across the World Cup — roughly twice the 2022 Qatar figure, and a number the Group says reflects the prediction market boom — means the surveillance challenge is orders of magnitude larger than anything prior watchdogs faced. The timing of this report, arriving one day after the House Agriculture Committee held its own hearing in Washington questioning whether prediction market platforms need more consumer protection and integrity oversight, ensures it will land in front of legislators already inclined to act.

Kalshi Suspends Congressional Candidate for Trading on Own Race — Senate Already Banned Members
Kalshi disclosed on August 31 that it suspended North Carolina congressional candidate Laurie Buckhout for three years and fined her $2,589 for trading on her own race — the first publicly known enforcement action against a candidate for prediction market insider trading. Kalshi said it found multiple politicians trading on races they were involved in, including former Congressman George Santos. The Senate had unanimously banned its members and staffers from prediction market trading on April 30. CNN published a major feature on September 24 documenting election officials' concerns about disinformation and insider trading risk from prediction markets as the midterms approach.
Pew Research: Prediction Market Volume Doubled May-July, Sports Now Largest Category
A Pew Research Center analysis published September 23 found that combined monthly trading volume on Kalshi and Polymarket more than doubled from May to July 2026 — rising from $26 billion in May to $53 billion in July — driven primarily by sports contracts. Sports is now the largest trading category on both platforms. During the FIFA World Cup in June and July, Kalshi's monthly sports volume reached $58 billion. Over the same period, Americans wagered roughly $40 billion at licensed sportsbooks — suggesting prediction market sports volume has approached or exceeded licensed sports betting in dollar terms.
Democrats Now 60% Senate, 90% House Favorites on Prediction Markets — Biggest Shift Since 2024
Prediction markets on Kalshi and Polymarket have moved decisively toward Democratic control of both congressional chambers in the 2026 midterms. Democrats are priced at approximately 60% to win Senate control (Republicans 40%) and roughly 90% to win House control as of September 21. Republicans had been at 80%+ in Senate control markets when the market opened in November 2024. The shift began in February 2026 following the Iran war and has accelerated through fall as rising gas prices pushed Trump's approval ratings lower. More than 500 active midterm markets are live across Kalshi and Polymarket combined.
