Météo-France Files Police Complaint Over 2 Paris Heat Spikes Tied to Polymarket Payouts

3 articles · Updated · CNN · Jul 17

Météo-France filed a police complaint after temperature readings at Charles de Gaulle airport suddenly jumped on April 6 and April 15, data that was used to settle Polymarket trades.
Those spikes triggered sizable payouts on unlikely Paris heat bets, fueling speculation that someone may have tampered with the airport sensor to influence the market.
Polymarket said it monitors for illegal activity and argued its blockchain-based system can help identify potential wrongdoers, while experts warned disaster and weather markets can create incentives for manipulation.
The case has widened scrutiny of prediction markets tied to wildfires and extreme weather, with critics warning they can normalize human suffering and even reward arson or other interference.
