Polymarket dispute erupts over Strategy Bitcoin sale
Prediction market platform Polymarket is facing growing criticism from traders after proposing a “No” resolution on a market tied to whether Strategy sold any bitcoin by May 31, despite the company later confirming a sale occurred during the specified period.
Strategy, formerly known as MicroStrategy, disclosed in a June 1 Form 8-K filing that it sold 32 BTC between May 26 and May 31 for approximately $2.5 million, marking the company's first reported bitcoin sale since December 2022.
“Confirmation achieved outside of the market’s time frame does not qualify,”
Polymarket indicated when explaining its preliminary decision to settle the market as “No.”
The dispute centres on whether the sale itself or the timing of public disclosure should determine the market outcome, with Polymarket arguing that no regulatory filing, on-chain evidence or credible reporting confirmed the transaction before the resolution deadline.
The market attracted more than $85 million in total trading volume, including $53.86 million linked specifically to the May 31 contract, making it one of the platform's most closely watched prediction markets.
Strategy said proceeds from the sale would support preferred stock distributions, with the transaction representing roughly 0.0038% of its 843,706 BTC treasury, although the move challenged the long-standing perception that Executive Chairman Michael Saylor never sells bitcoin.
The disagreement may ultimately be decided through UMA's Data Verification Mechanism, where token holders vote on disputed outcomes, while traders continue debating whether the platform's rules should prioritise the timing of the underlying event or the timing of its public confirmation.
At the time of reporting, Bitcoin price was $70,762.52.
