[A Man Used a Hair Dryer to Tamper with Paris Airport's Temperature Sensor, Profiting $34,000 on Polymarket Weather Market] Crypto KOL @aaronjmars disclosed on the X platform that a man profited approximately $34,000 by tampering with the temperature sensor at Paris Airport on the Polymarket weather prediction market. The market relies on a sensor located near the runway at Charles de Gaulle Airport, operated by the French Meteorological Agency, which is largely unattended. The man purchased low-probability temperature options at extremely low prices (e.g., 22°C, while the general expectation was 18°C), then used a portable heat source to briefly heat the air around the sensor, causing the temperature reading to spike and be recorded as the day's highest value. The temperature returned to normal within minutes, but the market had already settled based on his prediction. The man succeeded twice, on April 6 and April 15, until the French Meteorological Agency discovered the issue and filed a lawsuit.
