Strategy sold 32 Bitcoin before May 31, but Polymarket ruled the trade invalid because its 8-K filing came June 1. The decision wiped out a $527,000 bet and ignited criticism from market analysts.
The Deadline Dispute
Polymarket's $150 million prediction market hinged on whether Strategy sold Bitcoin by 11:59 p.m. ET on May 31. The company moved 32 Bitcoin worth $2.5 million between May 26 and 31. Yet administrators decided the sale didn't count—the public confirmation arrived June 1. They issued a retroactive clarification flipping the resolution to 'No' despite the transaction occurring on time.
A Wiped-Out Arbitrage
Trader 'willo2' staked $527,000 on 'Yes' immediately after seeing the 8-K filing. They expected a 20% gain from what seemed like a clear-cut win. Polymarket's ruling erased the entire stake. No appeal process existed for the loss.
Rules in the Dark
Arca's CIO Jeff Dorman and data scientist Jonatan Pallesen slammed Polymarket for not closing the market at the deadline. They noted the contract never specified public disclosure timing as a requirement—only that filings and on-chain data would be primary sources. Dorman called the outcome "a trap for retail bettors" and "fraud by omission." Pallesen agreed the setup was intentionally ambiguous. Traders now demand contract language changes before the next major market opens.
