A hair dryer? A lighter? A lucky coincidence?<\/p>

Authorities in France are investigating possible tampering with a weather monitoring device at Charles de Gaulle Airport in Paris after an unusual temperature spike was recorded around the same time a Polymarket trader cashed in.<\/p>

An anonymous trader with the username “xX25Xx” has drawn scrutiny from analysts and fellow traders on Polymarket, where people can bet on things like a city’s top temperature and other real-world events.<\/p>

The trader bet $119 that the weather in Paris on April 15 would jump past the equivalent of 64 degrees Fahrenheit, and weather enthusiasts online noticed a sudden spike in temperature on that day. Thanks to the sudden rise in temperature, the trader netted $21,398 in profit.<\/p>
