Gamblers allegedly tampered with weather station sensors to influence Polymarket bets, a popular online betting platform that allows wagers on various aspects of modern life. This follows a French investigation launched on April 23, 2026, into suspected tampering with a weather sensor at Paris-Charles de Gaulle airport. A French weather association suspects this incident is a betting scam. Earlier the same day, France’s national weather agency, Météo-France, confirmed it was investigating allegations that its weather data in Paris had been manipulated, filing a complaint with local authorities after Polymarket bettors reported significant wins on weather outcomes. France’s forecasting office had flagged suspected tampering with weather sensors at the country’s largest airport, referring the case to the police after detecting unusual readings alongside heavy betting on a prediction market. This suspected manipulation of weather data, tied to a prediction market payout, has renewed scrutiny around the “oracle problem” in blockchain systems, as the Météo France temperature sensor at Charles de Gaulle Airport was reportedly used by Polymarket to settle daily weather bets in Paris.
