Paris-Orly Airport

A person tampered with a temperature sensor at a Parisian airport to win a $20,000 bet on Polymarket, a prediction-market platform. French police are investigating the incident, which involves trespassing and equipment tampering, while concerns grow about how prediction markets may incentivize manipulating real-world events. A White House teleprompter operator also reportedly earned over $100,000 by betting on President Trump’s speeches via Kalshi.
