POLYMARKET DISPUTED RESOLUTION — EXPLAINED

Why Thousands of Traders Believe Polymarket's MicroStrategy Resolution Was Wrong

Published June 2026 — polymarketfraud.xyz

What Was the Market?

Polymarket listed a prediction market asking: “MicroStrategy sells any Bitcoin by May 31, 2026?” The market traded at $265M+ in volume. Thousands of traders bought YES positions at prices up to 70¢, believing MicroStrategy would sell Bitcoin before the deadline.

What Were the Written Rules?

“This market will resolve to ‘Yes’ if MicroStrategy sells any of its Bitcoin by 11:59 PM ET on the date specified in the title. Otherwise, this market will resolve to ‘No’.”

The rule says sells. It does not say “publicly discloses a sale.”

What Actually Happened?

May 26–31, 2026MicroStrategy reportedly sold 32 BTC on-chain
May 31, 2026Market deadline — 11:59 PM ET
June 1, 2026MicroStrategy filed SEC Form 8-K disclosing the sale
June 2, 2026Polymarket added "Additional Context" requiring public confirmation before deadline
After June 1Market resolved NO — YES traders received nothing

Why YES Traders Dispute This

The written rule never mentioned public disclosure. Polymarket added the disclosure requirement via “Additional Context” on June 2 — after the market deadline had already passed. YES traders argue that changing the resolution criteria retroactively is fundamentally unfair and potentially constitutes misrepresentation.
