Polymarket trader loses $527K after Strategy’s June 1 8-K reveals 32 BTC sale

A Polymarket user known onchain as "willo2" lost about $527,000 in a single day after a bet on Strategy’s bitcoin sale deadline resolved. Strategy disclosed in a June 1 Form 8-K that it sold 32 BTC for about $2.5 million, its first bitcoin sale since 2022. The position was tied to whether the company would sell any BTC before May 31, and the filing flipped the outcome.
