Integrity monitors flag seven World Cup betting alerts as FIFA declares finals free of fixing

An independent sports integrity network and world football’s governing body are offering sharply different assessments of the 2026 FIFA World Cup after monitors cited seven possible betting irregularities and FIFA said it uncovered no proof of match fixing.

Reporting by The Athletic, the Group of Copenhagen — an international coalition that tracks integrity risks in sport — reviewed wagering patterns and on-pitch developments from every one of the tournament’s 104 fixtures and issued seven “yellow notices.” The Council of Europe published a summary of those findings on Wednesday; the complete report has not yet been released.

Cases singled out in the summary included a late red card shown to South Africa’s Themba Zwane in the match against Mexico; more than US$4.8 million staked on the prediction platform Polymarket that Spain would fail to defeat Cape Verde ahead of a 0-0 result; and an extended VAR check that cancelled a goal scored by Spain’s Ferran Torres versus Saudi Arabia.

The monitors also pointed to a Polymarket market launched on July 2 posing the question, “Will Folarin Balogun play against Belgium?” before FIFA announced that the player’s suspension had been lifted. The Group of Copenhagen has asked FIFA for a written account of the Balogun episode, noting that comparable markets did not appear for other players dismissed during the finals.

FIFA rejects any suggestion that the tournament was compromised. In a statement issued on Tuesday, its Integrity Task Force said it watched betting markets and match events for the full competition and detected “no suspicious betting activity or indications of match manipulation” in any of the 104 contests.

According to The Athletic, the Group of Copenhagen assigns “yellow notices” when multiple signs of irregularity appear together. Those signs can include unexplained swings in betting odds, talk circulating on social media, or tip-offs from confidential contacts. Alerts sit on a four-colour scale: green for normal conditions, yellow for a slightly raised concern, orange for a higher concern, and red for the most serious level.

Gambling industry specialist Christian Kalb told The Athletic that alerts do not automatically equal wrongdoing and may reflect ordinary bookmaker behaviour, such as using prediction markets to hedge financial exposure.

The watchdog put total World Cup betting at roughly US$240 billion — about twice the volume seen at the 2022 finals — and said 15 matches were placed under heightened watch.
