Strategy, the business intelligence firm known for its massive Bitcoin holdings, has sold bitcoin for the first time in more than two and a half years. In an SEC filing, the company disclosed the sale of 32 BTC between May 26 and May 31, 2026, generating roughly $2.5 million. The proceeds were used to fund dividend payments on its preferred stock. This marks a significant departure from Strategy's long-standing accumulate-and-hold approach, which had not seen a single satoshi sold since December 2022.
The sale immediately drew attention on the decentralized prediction platform Polymarket, where a high-stakes market had been open betting on whether Strategy would sell any bitcoin before May 31. With over $20 million in total volume, the market became a flashpoint for a classic prediction-market dispute. Supporters of the “Yes” outcome argue that the sale demonstrably occurred within the deadline. The “No” camp, however, insists that material information was not publicly available when the market closed, and a prediction market should resolve based on facts that are knowable at the time of the deadline, not retroactively discovered details.
Final Review Leans Toward “No” as Polymarket Clarifies Rules
The market has now entered a final review phase. Polymarket has added a note stating that “outcomes confirmed after the deadline will not be recognized,” which strongly supports the “No” side. Even though Strategy’s sale happened before the cutoff, the delayed disclosure means that market participants could not have acted on that information. Unless the review process overturns this interpretation, the pool is expected to resolve as “No.”
If the dispute cannot be settled at the platform level, it will be escalated to UMA’s optimistic oracle system, where UMA token holders vote on the outcome. Such a process is designed to provide decentralized resolution, but it comes with its own set of problems.
UMA Vote Concentration Clouds Fairness Outlook
Earlier reports have highlighted a significant concentration of voting power in the UMA ecosystem. More than 60% of active voters have been found to have direct connections to Polymarket accounts. This overlap raises serious questions about the impartiality of a vote that directly affects a high-volume Polymarket market. Should the dispute reach a UMA vote, the same entities that stand to benefit from a particular resolution may end up being the decision-makers, undermining the trust that decentralized dispute resolution is meant to provide. For now, the prediction market community watches closely as the review unfolds, with the broader implications for governance token concentration in decentralized oracles hanging in the balance.
