Gate News message, April 23 — A user profited $34,000 on Polymarket’s weather prediction market by tampering with a temperature sensor at Paris Charles de Gaulle Airport. The user purchased temperature options at extremely low prices that were well above market expectations, then used a portable heat source to artificially raise the sensor’s readings, causing a spike that was recorded as the day’s high temperature.
Polymarket had previously settled its weather contracts using data from Météo France sensors located near the airport. The manipulation occurred on two separate occasions, April 6 and April 15, according to reports.
Météo France discovered the anomalies and has filed charges against the user for market manipulation.
