Polymarket Just Got Exploited in the Weirdest Way Possible: A Hair Dryer and a $34,000 Profit
In Paris, this incident exposed how fragile prediction markets can be. Polymarket was settling temperature bets based on a single physical sensor.
While the market expected around 18°C, one व्यक्ति went heavy on the unlikely 22°C outcome. Then he located the sensor near Charles de Gaulle Airport, went there in person, and literally heated it up with a hair dryer.
The sensor recorded that artificial spike as the day’s peak temperature. The market settled accordingly. Trade closed. Profit locked.
He reportedly repeated this twice and walked away with around $34,000.
The case is now facing legal action, but it highlights a deeper issue: when real-world data feeds rely on weak or single-point inputs, they become incredibly easy to manipulate.
