A user interfered with the Polymarket temperature prediction market by heating a weather sensor, profiting $34,000

A user profited $34,000 in the Polymarket weather prediction market by interfering with the weather sensors at Paris airport. Polymarket previously settled using data from Météo France sensors near Charles de Gaulle Airport in Paris, and the user bought temperature options at a very low price that were far above market expectations. The user then used a portable heat source to heat the sensor, causing the readings to spike significantly in a short period and be recorded as the highest temperature of the day. This behavior occurred twice on April 6 and April 15, and Météo France has now detected the anomalies and filed charges.
