An individual manipulated Polymarket's Paris weather market by tampering with a Météo France temperature sensor at Charles de Gaulle Airport using a portable heating device, likely a hair dryer. This act temporarily increased the temperature reading, allowing the individual to profit from long-shot bets on specific temperature outcomes. The manipulation occurred on April 6 and April 15, resulting in approximately $34,000 in gains. Météo France has lodged a criminal complaint with French authorities regarding the incident.
