<p><strong>A Polymarket trader has challenged the handling of a disputed market tied to Strategy’s Bitcoin sale, arguing that the written rules should count the sale date, not the disclosure date.</strong></p>

<p>The dispute centers on the market asking whether MicroStrategy, now known as Strategy, would sell any Bitcoin by May 31, 2026. The trader, known as 0xDinosaur on X, said the market wording did not clearly require the sale to be disclosed by the deadline.</p>

<p>In a public statement, the trader said he bought 49,695.76 YES shares for about 35,000 USDC. He said he accepts that the trade carried risk, but argued that risk does not allow a platform to apply an unclear rule after money has already been placed.</p>

<h2 class="wp-block-heading" id="strong-strategy-sale-created-timing-dispute-strong"><strong>Strategy sale created timing dispute</strong></h2>
<p>Strategy <a href="https://crypto.news/polymarket-users-challenge-outcome-of-80m-strategy-bitcoin-bet/" rel="noopener noreferrer nofollow">disclosed</a> in a June 1 filing that it sold 32 Bitcoin between May 26 and May 31. The company said the sale generated about $2.5 million at an average price of $77,135 per Bitcoin.</p>
<p>The company also said the proceeds are expected to fund distributions on preferred stock. As of May 31, Strategy still held 843,706 Bitcoin, bought for about $63.87 billion at an average price of $75,699.</p>
<p>Polymarket’s market rules say the contract resolves “Yes” if MicroStrategy sells any of its Bitcoin by 11:59 p.m. ET on the date in the title. The same rules list information from MSTR and on-chain data as the main resolution sources, while allowing credible reporting as another source.</p>
<p>The market page shows that “No” was proposed twice and disputed twice. It also shows the market in final review, meaning the outcome has not been fully settled.</p>
<p>The core question is simple but contested. Some traders argue that <a href="https://crypto.news/michael-saylor-breaks-silence-after-strategys-2-5m-bitcoin-sale/" rel="noopener noreferrer nofollow">Strategy</a> sold Bitcoin before the deadline. Others argue that the sale was not confirmed until June 1, after the market deadline passed.</p>
<p>0xDinosaur wrote that a sale date and a disclosure date are not the same thing. He also said “Prediction markets only work when users can trust that words mean what they say.”</p>
<h2 class="wp-block-heading" id="strong-broader-debate-hits-prediction-markets-strong"><strong>Broader debate hits prediction markets</strong></h2>
<p>The dispute adds fresh pressure on prediction market wording and resolution systems. These markets often depend on exact language, public sources and dispute rules that decide how real-money outcomes are settled.</p>
<p>Related coverage <a href="https://crypto.news/strategy-sends-30m-in-bitcoin-to-coinbase-as-mstr-stock-slides/" rel="noopener noreferrer nofollow">reported</a> that Strategy had sent 411.48 Bitcoin worth about $30.3 million to Coinbase Prime before the sale was disclosed. That transfer helped raise attention around whether the company was preparing to sell.</p>
<p>The dispute also follows fresh reporting on Strategy’s first Bitcoin sale since 2022. Strategy sold only a small part of its holdings, but the timing created a large market fight because the Polymarket question used the phrase “sells any Bitcoin by May 31.”</p>
<p>The case may now test how prediction markets treat events that happen before a deadline but become public after it. For traders, the final outcome may shape how future markets write rules around filings, on-chain data and official disclosures.</p>
