In a peculiar incident at Charles de Gaulle Airport in Paris, a man allegedly manipulated weather data to win significant amounts on Polymarket, a major prediction market. He placed bets on an improbable daily high temperature of 22°C while forecasts indicated it would be around 18°C. By using a hair dryer to heat the air near a temperature sensor operated by Météo-France, he temporarily inflated the recorded temperature, allowing him to win approximately $34,000 (around ₹32 lakh). This tactic was reportedly employed on two occasions, April 6 and April 15, before authorities identified the irregularities. Following the incident, Météo-France filed charges, emphasizing concerns about the integrity of prediction markets that depend on isolated data points. The case has sparked discussions regarding the vulnerabilities of decentralized prediction markets and the potential financial risks associated with real-world data feeds.
