On Polymarket, an account has just set a record for the highest ROI ever on weather prediction - polymarket

The user predicted that the highest temperature in Shenzhen would reach 27°C on March 29. At the time, the market probability was only 0.1%

It sounded like a random, for-fun bet - but it actually hit. A $5 bet returned $5,000 ~ a 99.900% PnL

What’s even more interesting is that this account’s history shows the owner only participates in weather prediction markets and nothing else
