Polymarket Draws Investigation After Concentrated Bets on Ballon d’Or Top-Five Finish
Twelve Polymarket accounts wagered $264,000 on the exact Ballon d’Or top-five order, with seven betting solely on this event and suspicious probability drops from 80-90% to 28%. France Football opened a probe with French police. Similar Israel election wins and March anti-insider rules expose ongoing verification gaps.
SCCG Take — Prediction platforms must tighten identity checks to curb manipulation risks that invite regulatory blocks and erode trust.
As reported by GamblingNews, insider trading activity on the prediction platform Polymarket may have targeted the Ballon d’Or award. Twelve accounts created between October 1 and October 20 wagered a total of $264,000 on the final top-five ranking of athletes: Harry Kane, Kylian Mbappé, Lamine Yamal, Rodri, and Lionel Messi in exact order.
Seven of these accounts placed only this single wager, with six doing so within 15 minutes of account creation. The betting patterns appear highly suspicious given that France Football insists on an independent voting process for the award. Contracts opened on September 29 initially assigned an 80% to 90% probability that Yamal would finish ahead of Mbappé. This held until October 8, then dropped to 55% on October 9 and 28% by October 22 with no sporting event or official statement to justify the move.
France Football has launched an official probe into the activity and confirmed that French police would participate. The organization stated that the integrity of the Ballon d’Or remains one of its top priorities.
Persistent Insider Trading Risks on Prediction Markets
Polymarket remains banned in France after regulators classified its contracts as gambling and ordered internet service providers to block access. Users continue to reach the platform through VPNs. The company faced parallel allegations in Israel, where hundreds of newly registered accounts made successful bets on the general election just before voting closed and generated more than $100,000 in combined profits. Polymarket said it would investigate and report the matter to law enforcement.
In March the platform introduced new rules that specifically banned trading based on stolen information and illegal tips. Proving such violations remains extremely challenging because Polymarket does not require user identity verification. These repeated episodes show the limits of current controls when participants can operate anonymously.
