Polymarket Faces Probe Over Suspicious $264,000 Ballon d’Or Bets Pointing to Possible Insider Activity

Prediction platform Polymarket faces fresh scrutiny after twelve accounts created between October 1 and October 20 wagered a total of $264,000 on the exact top-five Ballon d’Or finish order of Harry Kane, Kylian Mbappé, Lamine Yamal, Rodri, and Lionel Messi. Seven of those accounts placed bets only on this event, six of them within 15 minutes of account creation. As reported by GamblingNews, the patterns point to possible advance information ahead of the France Football award.

Price data showed contracts assigning an 80% to 90% probability of Yamal finishing ahead of Mbappé when they opened on September 29. That level held until October 8. The probability then fell to 55% on October 9 and reached 28% by October 22, with no public sporting event or statement to explain the move. France Football has launched an official probe, with French police involved, while stating that award integrity counts among its top priorities.

Persistent Insider Trading Patterns Across Polymarket Markets

The platform remains banned in France after regulators classified its contracts as gambling and ordered internet service providers to block access, though users continue to reach it through VPNs. Polymarket also investigated hundreds of newly registered accounts that placed successful bets on Israel’s general election just before polls closed, with some generating more than $100,000 in combined profits. In March the platform introduced new rules that specifically banned trading based on stolen information or illegal tips.

Proving access to privileged information stays extremely challenging. The absence of mandatory identity verification leaves the platform exposed to repeated abuse, as the latest Ballon d’Or activity demonstrates.

Closing the Enforcement Gap

Without reliable user verification and real-time anomaly detection tied to specific events, prediction markets will keep encountering these exact patterns. Regulators and platforms face a clear choice: tighten controls now or accept that non-public information will continue to distort outcomes and invite official intervention.
