Bitcoin Sale by Strategy Triggers $80M Polymarket Dispute
A Bitcoin sale by Michael Saylor’s Strategy has sparked a heated dispute on blockchain-based prediction market Polymarket, where $80 million was wagered on whether the company would sell Bitcoin (BTC) by May 31. Strategy disclosed on June 1 that it sold 32 BTC between May 26 and May 31, but Polymarket resolved the market to "No," leaving users outraged over what they see as a technicality.
The market, titled "MicroStrategy sells any Bitcoin by May 31," allowed users to buy positions on either "Yes" or "No." While Strategy’s sale reportedly took place within the specified timeframe, the company’s June 1 disclosure fell outside the window, prompting Polymarket to rule that the event did not qualify.
Polymarket clarified in an update: "No information from MSTR, on-chain data, or consensus of credible reporting confirmed that MicroStrategy sold Bitcoin within the market's timeframe." This decision has left many participants frustrated. One user wrote, "Polymarket should trade truth, not technicalities," while others expressed a loss of trust in the platform.
Final Decision Pending
The dispute is now under review, with Polymarket set to issue a final decision by 12:00 am UTC on June 3. If no further clarification is provided, the order book for the market will be cleared. This situation highlights the complexities of resolving binary prediction markets tied to nuanced real-world events.
Strategy’s Sale and Bitcoin’s Price Reaction
This marked Strategy’s first-ever sale of Bitcoin, a move that diverged from the company’s long-standing commitment to hold its BTC reserves indefinitely. The sale was first hinted at during Strategy’s Q1 earnings call on May 5, when Saylor described it as a way to "inoculate" the market against panic. Despite this rationale, the company’s decision rattled both its investors and Bitcoin traders.
Bitcoin dropped 2.5% to $70,815 within hours of the disclosure on June 1, before rebounding slightly to $71,200. As of June 2, BTC is trading at $70,896.07, down 3.95% in the last 24 hours, reflecting broader market uncertainty. Bitcoin’s current market cap stands at $1.42 trillion.
Polymarket’s Growing Scrutiny
This dispute comes at a challenging time for Polymarket. In May 2026 alone, the platform faced heightened regulatory scrutiny and operational setbacks, including insider trading charges linked to $1.2 million in wagers and confirmation of a $700,000 loss from a private key hack. These issues have raised questions about the platform’s ability to maintain transparency and security.
Founded in 2020, Polymarket has positioned itself as a key player in blockchain-based prediction markets, where traders speculate on real-world events using tokenized binary contracts. However, its handling of this $80 million Bitcoin market could have lasting implications for user trust and the platform’s reputation.
Market participants and traders are now closely watching Polymarket’s decision, as well as Bitcoin’s price action, for further developments. With BTC volatility rising and prediction market outcomes under scrutiny, this event underscores the intersection of blockchain technology, market dynamics, and corporate transparency.
