One guy just faked the weather and cashed out $22K


French police opened a criminal case over the dumbest Polymarket exploit ever
Paris weather contract relied on ONE sensor at Charles de Gaulle Airport
Unattended. Near a runway
He found it
Had a hairdryer
April 15
16.9°C → 21.9°C in 12 minutes
Humidity drops same time
That spike locks the daily high → his bet wins
$590K volume
He walks with ~$22K
Météo-France flagged it first. Humidity exposed him
One hairdryer broke a billion dollar market
How many “secure” oracles are this fragile?
