A new analysis argues that crypto-based prediction markets operating outside traditional banking oversight could make football's biggest tournament a channel for money laundering, illicit betting and match manipulation. With global World Cup wagering estimated to exceed $50 billion, the report frames the integrity risk as structural rather than incidental.
The Global Initiative Against Transnational Organized Crime has warned that crypto-based prediction markets could make the 2026 FIFA World Cup a vehicle for money laundering, illicit betting and match manipulation. The warning comes in an analysis by Jennifer Okeyo-Robert, published on 10 June 2026, that examines how the rapid growth of event-contract platforms intersects with the largest football tournament ever staged.
At the centre of the report is a mechanism rather than a single incident. Prediction markets, it argues, can convert illicit funds into "apparently legitimate winnings" while operating outside the traditional banking oversight that applies to regulated bookmakers and payment providers. That combination, the analysis contends, offers a route to launder money and to place manipulated bets with reduced visibility for investigators.
The report attaches striking figures to that thesis, though several warrant caution. It claims that wash trading, the practice of trading with oneself to inflate apparent volume, accounts for around 25% of activity on Polymarket, rising to roughly 60% at peak. Those percentages are the author's own estimates, presented in the report and not independently confirmed, and should be read as an allegation about the scale of manipulation rather than an audited measurement.
On the wider market, the analysis estimates that global betting on the 2026 World Cup will exceed $50 billion, up from around $35 billion at the 2022 tournament. It sets that against an illicit betting backdrop it puts at up to $1.7 trillion wagered worldwide each year, the figure it uses to argue that even a small diversion of manipulated flows would be significant in absolute terms.
Platform-level data cited in the report underlines how quickly the sector has scaled. Polymarket is said to have processed an estimated $9 billion through its unregulated international exchange in April 2026, with combined monthly trading across Polymarket and Kalshi put at around $24 billion in the same month. The report also references FIFA's roughly $150 million prediction-markets partnership with ADI Predictstreet, framing the sport's own commercial embrace of event contracts as part of the context regulators must weigh.
The governing body has signalled that it is treating integrity as a priority. The FIFA Integrity Task Force met in Miami on 7 May 2026, and Emilio Garcia Silvero, FIFA Chief Legal and Compliance Officer, described the mandate as safeguarding the tournament "through vigilance, coordination and decisive action." The 2026 FIFA World Cup, expanded to 48 teams and 104 matches and co-hosted by the United States, Canada and Mexico, opened on 11 June 2026.
The Banking-Oversight Gap Is the Argument That Should Worry Regulators Most
The report's sharpest point is not the size of the market but where it sits. Regulated bookmakers operate inside a payments system built for anti-money-laundering controls, with identifiable counterparties and reporting obligations. Crypto-based prediction markets, by the report's account, sit substantially outside that perimeter, which is what allows illicit funds to emerge as apparently legitimate winnings. That is a structural feature, not a rogue-operator problem, and it is why the concern travels beyond any single event. A World Cup simply concentrates liquidity, attention and betting interest into a few weeks, magnifying whatever weaknesses already exist. The counter-consideration is that scale also invites scrutiny, and the largest platforms have incentives to demonstrate clean books. But an incentive to look clean is not the same as external supervision, and the gap the report identifies is precisely the absence of the latter.
The Wash-Trading Figures Are Alarming and Unproven, and Both Facts Matter
A claim that 25% of Polymarket's activity, rising to 60% at peak, is wash trading would, if accurate, undermine confidence in the market's headline volumes and by extension in the pricing that makes prediction markets attractive. It would also strengthen the laundering thesis, because inflated, self-dealt volume is exactly the kind of noise in which illicit flows can hide. But these are the report's own estimates, not independently confirmed, and the methodology behind them is not something an outside reader can test. The responsible reading holds both facts at once: the allegation is serious enough to justify independent examination of on-chain activity, and it is unverified enough that it should not yet be treated as established. Regulators assessing the sector need audited data, not contested percentages, before acting on numbers of this magnitude.
FIFA Cannot Be Both a Commercial Partner and the Referee of the Same Market
The most awkward tension the report surfaces is FIFA's own position. A roughly $150 million partnership with a prediction-markets business places the governing body on the commercial side of the very product its Integrity Task Force is charged with policing. That does not make the partnership improper, and Garcia Silvero's framing of vigilance and coordination is the right language. But it does create a credibility test that vigilance alone will not pass. If the tournament's guardian derives revenue from prediction markets while warning about their risks, independent oversight becomes essential rather than optional, so that integrity decisions are not seen through the lens of a commercial relationship. The report's underlying warning is sound even where its individual figures are contestable: a market this large, this fast and this lightly supervised deserves external scrutiny before the final, not a post-mortem after it.
