Polymarket Faces $14.65 Million Contract Dispute After Strategy Discloses Bitcoin Sale
Claire Weston
Strategy confirmed it sold bitcoin in late May, but the 8-K filing landed only on June 1 — leaving a $14.65 million Polymarket contract in limbo over one question: does the date of the act or the date of disclosure decide the outcome?
What was the contract betting on?
A Polymarket contract asked: did Strategy sell any bitcoin before May 31? It drew $14.65 million in volume, with the "Yes" side priced at 81%.
The rules were explicit: if Strategy sold any bitcoin before 11:59 PM ET on May 31, the contract settles "Yes."
Three types of evidence count: MSTR's SEC filings, on-chain data, and credible reporting consensus.
What exactly is the dispute about?
Strategy did sell bitcoin between May 26 and May 31 — both sides agree on this.
The catch: the 8-K disclosing the sale was filed with the SEC on June 1, after the contract's cutoff.
This means → the fight is not over whether a sale happened, but over how to define the moment "public information" exists.
How do the two sides read the same rules?
"Yes" holders argue: the 8-K filing itself shows the sale occurred before May 31. The contract says it settles based on "bitcoin activity as presented at 4 PM ET on May 31" — the activity happened, so it should settle "Yes."
"No" holders argue: before the June 1 filing, no public information indicated a sale. Disclosure came after the deadline, so the contract should settle "No."
In plain terms = one side reads "when the event occurred," the other reads "when the event became public" — same contract language, two opposite conclusions.
How did other contracts react?
Beyond the May 31 contract, Polymarket hosts two more on the same question: June 30 and December 31 expiry dates.
Once the disclosure hit, both priced instantly to 100% "Yes" — "Yes" quoted at 99.9 cents, "No" at 0.1 cents.
Combined volume across all three contracts: roughly $24.7 million. The May 31 contract alone accounts for $14.65 million — the epicenter of the dispute.
Who makes the final call?
Polymarket uses UMA's Optimistic Oracle — an on-chain dispute-resolution mechanism — to adjudicate contested settlements, typically within two days.
This reflects a structural tension in prediction markets: no matter how precisely a contract is worded, a gap between event timing and disclosure timing can still create grey zones.
Did the market see this coming?
Before the disclosure, Polymarket's implied probability that Strategy would sell bitcoin by year-end had already climbed from 10% in early spring to 84%.
The turning point: Strategy CEO Phong Le's Q1 earnings call, where he listed "disciplined bitcoin sales" as a capital-management tool.
This means → the market was not blindsided by the sale itself. The real surprise was the settlement dispute triggered by the disclosure timing gap.
