French authorities are investigating suspected manipulation of weather sensor readings at Paris Charles de Gaulle Airport after unusual temperature spikes were recorded on 6 and 15 April, according to Dagens PS. The airport weather station data is used for flight safety and was also referenced for temperature-related contracts on the prediction market Polymarket, prompting concerns the measurements may have been influenced. Following the incidents, Polymarket reportedly changed the data source for its Paris temperature markets to another nearby airport.
