Polymarket rules against May bettors in Strategy bitcoin sale dispute

Polymarket's oracle system has ruled against bettors who wagered that Strategy would sell bitcoin by May 31, after a dispute over whether a sale disclosed on June 1 should count toward the May market.

Strategy, formerly known as MicroStrategy, disclosed in a June 1 filing that it had sold 32 bitcoin between May 26 and May 31. This was the company's first bitcoin sale in over three years. Traders who bought Yes on the May market argued that the sale clearly occurred before the May 31 deadline. However, opponents countered that the transaction was not publicly disclosed until June 1 and therefore should not count toward a May cutoff. The dispute was escalated to UMA token holders, who serve as the dispute-resolution layer for Polymarket's oracle system. They ultimately ruled in favor of the No position, meaning the sale does not count for the May market. As a result, the May market resolved to No, while the June market remains active with Yes trading.

This event highlights the importance of oracle timing in decentralized prediction markets. For crypto traders, the ruling underscores the nuances of on-chain data versus public disclosure dates. Live crypto prices and charts on NowPrice show how the market is reacting to this news, with Polymarket's native token UMA seeing increased volatility. The dispute also raises questions about how similar events will be handled in the future, especially as more companies hold bitcoin on their balance sheets.

Looking ahead, the June market on Polymarket will be closely watched. If Strategy sells more bitcoin before June 30, the Yes position could pay out. Traders should also monitor Strategy's future filings and any changes to its bitcoin treasury policy. The broader implications for prediction markets include potential adjustments to oracle rules to avoid similar disputes.
