Polymarket rules May 'No' on Strategy BTC sale despite…

Polymarket has resolved its disputed bitcoin-sale prediction markets, ruling the May 31 contract No and the June 30 contract Yes — a decision that left bettors who correctly identified the sale's timing empty-handed. UMA token holders, who serve as the oracle dispute layer for Polymarket, sided with the view that only Strategy's June 1 public disclosure date mattered, not the actual sale window of May 26–31.

Why it matters

The controversy cuts to the heart of how decentralized prediction markets handle ambiguous resolution criteria. Strategy disclosed in a June 1 SEC Form 8-K that it had sold 32 BTC during the final week of May — its first bitcoin sale in over three years. Traders who held Yes on the May contract argued the sale plainly occurred before the deadline. Galaxy Research pushed back sharply, stating: "A plain reading of the resolution criteria would suggest that the market should have resolved to YES, hence the controversy."

The governance mechanics drew equal scrutiny. The four largest No voters — including borntoolate.eth with 3.11 million voting weight and UMA contributor Kevin Chan with 1.53 million — controlled nearly 7 million voting weight combined, more than 25 times the entire Yes side. Several wallets linked to Risk Labs, the company behind UMA, also voted No, raising questions about whether a small group of insiders effectively determined the outcome.

Market impact

For BTC markets the direct price impact is limited, but the episode adds a layer of reputational risk to decentralized oracle systems and prediction markets broadly. If large token holders affiliated with the protocol's own developers can swing governance votes, the "decentralized" label on dispute resolution faces a credibility test.
