A heated dispute has erupted on prediction market platform Polymarket after a market involving Strategy’s Bitcoin sales generated more than $80 million in trading volume and became the subject of a final review process.
The controversy centers on a market that asked whether Strategy would sell Bitcoin before May 31. The company later disclosed in a regulatory filing that it had sold 32 Bitcoin, worth approximately $2.5 million, between May 26 and May 31.
While the sale itself took place within the timeframe specified by the market, the public disclosure was not made until June 1. Because the information became public after the deadline, Polymarket initially proposed resolving the market as “No.”
According to the platform, there was no publicly available confirmation of the sale before the deadline expired. Polymarket argued that neither company statements, on-chain evidence, nor credible media reports confirmed the transaction during the period covered by the market.
However, many users strongly disagreed with that interpretation. Critics argued that the actual event occurred before May 31 and that the market should be settled based on when the sale happened rather than when it was publicly disclosed.
The disagreement sparked intense debate among traders, with some users accusing the platform of relying on technical interpretations instead of focusing on the real-world outcome. Others questioned whether the market rules were being applied fairly.
As a result of the dispute, the final decision has been passed to holders of the UMA token, whose decentralized oracle system is used by Polymarket to resolve contested markets. UMA voters will determine whether the market should settle as “Yes” or “No” after reviewing the circumstances.
The dispute follows another significant development involving Strategy, formerly known as MicroStrategy. The company recently disclosed its first Bitcoin sale since 2022, ending years of public statements suggesting it would not sell any of its holdings. Despite the sale, Strategy continues to hold more than $60 billion worth of Bitcoin.
The case has also renewed broader discussions about how prediction markets should handle events that occur before a deadline but are only confirmed afterward. The outcome could influence how future markets are designed and interpreted.
This is not the first time Polymarket has faced controversy over market resolution. Last year, a high-profile dispute involving a market about Ukrainian President Volodymyr Zelenskyy’s clothing choices generated hundreds of millions of dollars in trading volume and ultimately required intervention from UMA tokenholders after users disagreed over the interpretation of the market’s terms.
For now, participants in the Strategy market are awaiting the final ruling, which will determine whether the decisive factor is the timing of the Bitcoin sale itself or the timing of its public confirmation.
