[A Polymarket User Loses $500,000 Due to 'Strategy Prediction Event'] Foresight News reports that Polymarket user willo2 tweeted about losing approximately $500,000 in the 'Will Strategy sell Bitcoin before May 31' prediction event due to Polymarket adding rule interpretations after the market had closed. The user held a position on the 'YES' side of the event. They claimed that Polymarket deliberately waited until after the release of Strategy's documents to clarify the rules, effectively modifying them retroactively. The user accused the platform of undermining user trust and called for accountability. According to a previous report by Foresight News, Strategy disclosed in documents submitted to the SEC that it sold 32 BTC between May 26 and May 31 to support preferred stock dividends. This action directly impacted the prediction outcome of the 'Will Strategy sell Bitcoin before May 31' event on Polymarket. The event has been repeatedly ruled as 'No' (did not sell), but Strategy's disclosure indicates that the sale did occur before the deadline.
