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

A user profited $34,000 by interfering with the weather sensors at Paris Airport in the Polymarket weather prediction market. 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 for a short time 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.
