Integrity Of World Cup Under Scrutiny Over Potential Betting Irregularities, Match Manipulation
he integrity of the 2026 FIFA World Cup has come under scrutiny following reports of possible betting irregularities and potential match manipulation. The Group of Copenhagen, an independent international body focused on protecting sporting competitions from manipulation, monitored all 104 matches and identified several situations that warranted closer examination.
During the tournament, 15 matches were placed under enhanced surveillance, particularly games played on the final day of the group stage. The organization issued seven “yellow notices,” indicating a slightly elevated level of concern, and examined 12 major controversies involving potential integrity risks. Its alert system ranges from green for normal activity to red for the highest level of concern.
A significant new element was the monitoring of prediction markets such as Polymarket and Kalshi. Several unusual events attracted attention. These included the late red card shown to South Africa’s Themba Zwane against Mexico, roughly $4.8 million being placed on Polymarket on Spain not defeating Cape Verde before the match ended 0–0, and a lengthy VAR review that disallowed a Ferran Torres goal during Spain’s victory over Saudi Arabia.
Perhaps the most unusual case involved US striker Folarin Balogun. Polymarket opened a market asking whether Balogun would play against Belgium on July 2, the same day he received a red card. FIFA did not publicly confirm that his suspension had been lifted until July 5. According to the report cited by BroBible, similar markets were not created for the other 14 players who received red cards, and none of those players subsequently had their suspensions lifted. The Group of Copenhagen has formally requested a written explanation from FIFA regarding the situation.
