A disputed Polymarket contract on whether Strategy sold Bitcoin by May 31 resolved to “No” after two dispute rounds, despite Strategy later disclosing that it sold 32 BTC during the market’s covered window.
UMA Optimistic Oracle (UMA) token holders voted to settle the market in “no” following a second resolution cycle that closed at 12:34 am UTC on Thursday, blockchain <a href="https://polygonscan.com/tx/0xbb5bb53cba59e644eb78ed0c194de60f2740ad7e5131b666968a9c6ff759ff6d" rel="noopener noreferrer nofollow">data</a> shows. An overwhelming 98.6% of the 607 participants voted for the market to resolve in “no,” while only 1.4% voted “yes,” <a href="https://www.betmoar.fun/market/microstrategy-sells-any-bitcoin-by-may-31-2026?tab=UMA" rel="noopener noreferrer nofollow">data</a> from Betmoar shows.
Polymarket said that no information, onchain data or credible reporting confirmed a Strategy sale within the market's timeframe, adding that confirmation achieved “outside of the market's time frame does not qualify.”
Strategy <a href="https://cointelegraph.com/news/strategy-first-ever-bitcoin-sale-offloads-32-btc" rel="noopener noreferrer nofollow">sold 32 BTC between May 26 and May 31</a>, but disclosed the sale in a Monday filing, after the market’s deadline.
The resolution adds to concerns about Polymarket's token-weighted dispute resolution system, where the wallets with the largest UMA token holdings have proportionally more voting power.&nbsp;
Multiple users cried foul, arguing that the market should have resolved based on when the sale occurred rather than when it was confirmed. One unfortunate trader <a href="https://x.com/willo2_Poly/status/2061640812132516321" rel="noopener noreferrer nofollow">reported</a> a $500,000 loss tied to their event contract. <a href="https://cointelegraph.com/news/strategys-bitcoin-sale-causes-clash-on-80m-in-polymarket-bets" rel="noopener noreferrer nofollow">Over $80 million</a> had been <a href="https://polymarket.com/event/microstrategy-sell-any-bitcoin-in-2025" rel="noopener noreferrer nofollow">wagered</a> on whether Strategy would sell Bitcoin by May 31, Cointelegraph reported on Tuesday.

“Prediction markets should price what happens, not how the oracle will reinterpret rules after the fact,” as resolution integrity “trumps any single outcome,” said Galaxy Research in a Wednesday X <a href="https://x.com/glxyresearch/status/2062255214791434382" rel="noopener noreferrer nofollow">post</a>, adding:
<blockquote>
 “We outline clear fixes: lock criteria at listing, deterministic resolution for verifiable events, and structural changes ahead of CFTC regulation.”
</blockquote>
Galaxy also <a href="https://x.com/glxyresearch/status/2062255218574643530" rel="noopener noreferrer nofollow">disclosed</a> a financial interest in the market, adding that it bought “yes” shares as part of its strategy to routinely hedge prediction market positions.
Polymarket declined to comment on the outcome of the contract or whether it would undertake a further review of the market.

The largest vote in the dispute came from blockchain wallet <a href="https://etherscan.io/address/0xfc204fcfd2a579157898a212ea25ac98de2b1e1c" rel="noopener noreferrer nofollow">borntoolate</a>.eth, which held 3.11 million UMA tokens, followed by Kevin <a href="https://etherscan.io/address/0xd2a78bb82389d30075144d17e782964918999f7f" rel="noopener noreferrer nofollow">Chan</a> with wallet "0xd2a," who held 1.53 million tokens.
Dispute resolution can be profitable for large token holders. Wallet borntoolate.eth netted over $299,000 from voting on event contract disputes, while the Kevin Chan-tagged wallet bagged over $370,000.

Critics also pointed to earlier disputed Polymarket resolutions as evidence of broader concerns with UMA’s token-weighted voting model.

Multiple users called it a “governance attack and whale manipulation but Polymarket did nothing with it,” commented Polymarket trader fr1ko.eth in a Tuesday X <a href="https://x.com/fr1ko_eth/status/2061782585827524776" rel="noopener noreferrer nofollow">post</a>.
