Polymarket is facing backlash after a Strategy Bitcoin sale market resolved to No, even though Strategy later disclosed it sold 32 BTC before May 31. Traders say the contract asked whether a sale happened, while the resolution focused on when the sale became public. The dispute has raised concerns about rule changes, timing, and trust in prediction markets among users.
Strategy disclosed on June 1 that it sold 32 BTC between May 26 and May 31. The filing described the sale as its first Bitcoin sale since 2022. The disclosure came after the Polymarket market’s stated end date.

The market asked, “Will Strategy sell any Bitcoin before May 31?” After the filing, YES shares moved above 80 cents, based on the account shared by traders. Many buyers argued that the sale date answered the market question.
According to the account, traders then bought YES shares after viewing the filing as evidence. The market size was described as more than $20 million by users discussing the result. That size helped turn a narrow rule dispute into a public test for Polymarket.
The outcome later moved toward No after Polymarket added a clarification to the market page. The added note stated, “Confirmation achieved outside of the market’s time frame does not qualify.” That line became the main issue for many YES holders.
They said the original wording centered on whether Strategy sold Bitcoin before the deadline. They argued it did not require public confirmation before May 31. NO holders relied on the later clarification and the need for verifiable confirmation.
YES holders said the added line changed the practical test after trading had taken place. They argued users priced the contract based on the words shown before the dispute. Polymarket’s position, as described in the dispute, centered on confirmation within the market window.
One trader, BTCBeliever21, said he bought 200,000 YES shares for about $15,000. He said the position later rose above $150,000 before the market resolved against him. He also said he was the largest holder and initiated a dispute. Other YES holders made similar complaints after the result moved against them.
Some traders also claimed large UMA holders built NO positions while the dispute remained open. Those claims have not been independently verified in the material provided. BTCBeliever21 said he bought at an average price near 7.5 cents. At the peak, he said the position was worth more than ten times his cost. The account made the case more visible across crypto trading circles.
The dispute also shows why wording matters in prediction markets. A single clause can separate a bet on an event from a bet on disclosure. Clear rules help traders understand what evidence will count before money enters a market. That point is central when companies report activity after month end.
