French police are investigating suspicions that a hairdryer may have been used to tamper with official weather readings to make thousands of dollars in Polymarket bets.

Temperature readings at Paris’s Charles de Gaulle airport have unexpectedly spiked twice in the last month, reaching levels much higher than expected.

On both days, gamblers on Polymarket, the world’s biggest prediction market, appear to have made huge sums by betting on unlikely weather patterns. The site relied on readings from the Charles de Gaulle temperature sensor.

Météo-France, the country’s official weather agency, said it had complained to police after noticing a change to one of its temperature sensors.

      Now I wonder what would happen if people bet on a Republican victory in the US midterms.

      Or, more ambitiously: “Donald John Trump will NOT be sentenced for Epstein related stuff before the end of the decade.”

      Basically bett- ahem- “investing” against the event one actually wants to happen to make it more likely to happen (and the worst case scenario is that one miswrites or misreads the bet and messes up. Anything else - good thing happens, one wins, or Polymarket goes down for good - is some form of win.)

      This is the kind of site that soon enough will be in the news for something horrendously bad because the owner or a group of users decided that the law is just a mere suggestion to them. I’ve seen this happening too many times already
