Polymarket Faces Backlash Over Disputed Strategy Bitcoin Sale Market

UMA voters upheld a final No outcome after tying settlement to Strategy’s June 1 disclosure, despite the company’s filing saying a 32-BTC sale occurred during the final week of May.

Fact Check
The primary source (Strategy's SEC 8-K filing dated May 30, 2026) directly confirms the 32 BTC sale for ~$2.5M between May 26-31. The Block's coverage corroborates both the sale and the Polymarket contract dispute over whether the sale (occurring before May 31 but disclosed June 1) should resolve the market 'Yes.' BlockchainReporter independently confirms the $118M Polymarket market and its disputed 'No' resolution.
Summary

Polymarket upheld a final "No" resolution in a disputed market over whether Strategy sold any bitcoin by May 31 after a UMA vote in which about 98.6% of voting power backed that outcome. The dispute centered on Strategy’s June 1 8-K filing, which said the company sold 32 BTC for roughly $2.5 million between May 26 and May 31, but the contract was effectively settled based on the date of public disclosure rather than the timing of the sale itself. The decision triggered backlash from traders and broader criticism over rule clarity, resolution integrity and trust in prediction markets.
