There is massive chaos on Polymarket right now regarding the "MicroStrategy sells any Bitcoin by May 31, 2026" market (currently sitting "In Review" at ~63%).
MicroStrategy has officially filed and declared that they indeed sold Bitcoin within the specific time period specified by the market rules.
If you play your cards right, you can structure a completely risk-free delta-neutral freeroll.
Here is exactly how this works and how to position yourself for maximum EV. π
The Precedent: September's Disputed Market
To understand the play, we look back at the similar disputed market from September
polymarket.com/event/microstβ¦
In that market, Polymarket resolved the contract but added a crucial caveat:
"This market will resolve to 'Yes'. All 'No' trades prior to the initial clarification (2025-09-02 15:00:46) will be refunded."
Essentially, anyone who bet against the rules before Polymarket explicitly clarified them got their money back.
The Current Situation (May 31 Market)
Look at
polymarket.com/event/microstβ¦
Polymarket just posted notice that a clarification is coming on June 1 at 1:00 PM ET.
Crucially, they have NOT added the specific "refund rules" to the interface yet. This leaves a massive structural loophole. If they follow the exact same playbook as September, any trades placed before the official rules are codified are eligible for a conditional refund if things go sideways.
The Ultimate EV Strategy: Go Delta Neutral
By utilizing the following math, you can lock in a zero-risk profit loop right now before the final notice drops.
Assume the current odds are 60% YES / 40% NO (or similar, like the 63.2Β’ / 36.9Β’ split you buy an equal amount of shares on both sides:
Buy 1,000 YES shares at $0.40 (Cost: $400)
Buy 1,000 NO shares at $0.60 (Cost: $600)
Total Outlay: $1,000
The Payoff Matrix (The Ultimate Freeroll)
Case A (Normal Resolution): The market settles normally. One side wins, the other loses. You get $1,000 back. Net profit: $0 (Completely risk-free, feeless trade).
Case B (YES Resolves, NO is Refunded): You get $1,000 from your YES shares your $600 back for the NO refund. Net profit: $600.
Case C (NO Resolves, YES is Refunded): You get $1,000 from your NO shares your $400 back for the YES refund. Net profit: $400.
What's the Catch?
The only reason this market hasn't been completely arbitraged to death is that the open interest is massive (around $7.5M ). Polymarket refunding a position of this scale would cost a fortune, meaning some traders are hesitant to trust they will fully honor the September precedent.
But since Polymarket limit order trades are essentially feeless, putting a portion of capital into a delta-neutral position here is a mathematically pure freeroll.
Positions are filling up fast. Get neutral before the 1:00 PM ET clarification hits the chain! β³
