Suspected Weather Data Manipulation Sparks Investigation into Polymarket Wins

A police investigation has been launched into suspected data manipulation at a French weather station after two Polymarket traders secured approximately $37,000 in winnings through highly improbable temperature readings. The incidents occurred at the Charles de Gaulle Airport station, where temperature spikes were recorded that did not appear on nearby monitoring stations. This event has raised significant concerns regarding the integrity of prediction markets and the potential for physical-world tampering to influence digital betting outcomes. On April 6, the temperature suddenly climbed above 21 degrees Celsius, resulting in a payout of over $16,000. A similar event occurred on April 15, where the temperature spiked to 22 degrees Celsius from a baseline of 18 degrees, allowing a trader to profit more than $21,000. Blockchain analysis provided by Bubblemaps revealed that a specific trader began buying 'NO' shares on the 18-degree outcome immediately before the spike occurred. Meteorologist Ruben Hallali suggested the variations were unlikely to be natural and pointed toward possible onsite intervention by an individual familiar with the sensor hardware. In response to the anomalies, Météo France, the official government weather agency, has filed a formal complaint with the Roissy Air Transport Gendarmerie Brigade for the alleged tampering of automated data processing systems. This incident adds to the growing regulatory scrutiny facing prediction markets, which are increasingly under fire for potential insider trading and violations of gambling legislation.
