Key Takeaways:
Météo France filed a complaint with Roissy airport gendarmerie after two CDG sensor anomalies on April 6 and April 15 aligned with Polymarket payouts totaling roughly $34,000. Meteorologist Paul Marquis of E-Meteo Service ruled out natural causes, concluding physical intervention with a heat device was the most probable explanation. Polymarket switched its Paris temperature resolution source to Le Bourget Airport on April 19, though no arrests have been made at the time of publication. French Meteorological Service Files Complaint After Paris Airport Sensor Data Aligns With Polymarket PayoutsNo neighboring stations recorded similar changes during either event. Wind direction and relative humidity showed no corresponding shifts.
Paul Marquis, meteorologist and founder of E-Meteo Service, said the pattern is hard to explain naturally. “There was no change in wind direction or relative humidity, and the other stations recorded nothing,” Marquis told Le Figaro. He said a physical intervention with a heating device placed near the sensor probe was the most plausible explanation.
The combined total from both events reached approximately $34,000. Polymarket users flagged the activity in real time, with comments citing manipulation and insider trading.
The investigation remains open.
