Key Takeaways
- • Strategy (formerly MicroStrategy) sold 32 bitcoin between May 26–31 to fund dividend payments on preferred stock, generating $2.5 million in proceeds, marking the company's first publicized bitcoin disposition despite years of Michael Saylor's "never sell" positioning.
- • A $15 million Polymarket prediction contract on whether Strategy would sell bitcoin by May 31 is trapped in resolution dispute, with the May 31 contract sitting at 81% "Yes" and flagged "in review" due to conflicting interpretations of settlement rules.
- • Bettors are split on whether the resolution should be based on onchain transaction dates (May 26–31) or the official 8-K filing date (June 1), creating uncertainty over which timestamp controls under the contract's rules requiring "consensus of credible reporting" and onchain data verification.
- • Saylor previously signaled that Strategy could sell "a small portion" of holdings to meet preferred stock dividend obligations, positioning this sale as a liquidity management decision rather than a shift in long-term bitcoin strategy.
- • Strategy simultaneously acquired 850 bitcoin for $99.7 million last week at an average price of $117,344, bringing total holdings to 639,825 coins and maintaining an overall average purchase cost of $73,971 per bitcoin.
Summary
Strategy's first publicized bitcoin sale has triggered a significant dispute in cryptocurrency derivatives markets, with a $15 million prediction market contract now entangled in a resolution controversy over settlement criteria. The company sold 32 bitcoin between May 26 and May 31 to fund dividend payments on its preferred stock, according to an 8-K filing issued on June 1, 2026. While the onchain transactions occurred in late May, the formal disclosure delay has created ambiguity in how Polymarket's time-stamped betting contracts should resolve.
The core dispute centers on conflicting resolution rules. Polymarket's "MicroStrategy sells any Bitcoin by ___?" contract requires settlement based on MSTR filings and onchain data, with consensus of credible reporting as backup. Yes-contract holders argue that since the bitcoin disposition occurred before May 31—as documented in the 8-K's transaction table—the May 31 deadline contract should settle in their favor. The opposing view holds that the June 1 filing date controls settlement, meaning the May 31 contract technically resolved before public disclosure occurred. The contract is currently weighted 81% toward "Yes" and flagged for manual review by market operators.
This sale represents a notable tactical shift for Michael Saylor, whose Strategy has maintained an aggressive bitcoin accumulation posture for years. Saylor has repeatedly emphasized a "never sell" philosophy publicly, but previously signaled flexibility, stating the company could sell "a small portion" of holdings to meet preferred stock obligations. The $2.5 million sale appears consistent with this framework, positioning the disposition as a dividend management tool rather than a strategic reallocation away from bitcoin holdings. The timing is further contextualized by Strategy's concurrent $99.7 million bitcoin purchase of 850 coins last week at $117,344 per coin, underscoring continued net accumulation despite the modest sale.
The resolution dispute underscores the structural challenges emerging in prediction markets tied to corporate disclosure timing. With $15 million in notional value at stake, the outcome will likely establish precedent for how future crypto-linked prediction contracts handle gaps between transaction execution dates and formal SEC filing dates. Strategy's holdings now stand at 639,825 bitcoin following the transactions, with an average cost basis of $73,971 per coin.
