Details

How it’s derived

A YES share pays one MSTR if it happens and nothing otherwise, so its price is roughly the chance it happens times what MSTR would be worth then. Divide out the chance and what is left is the market’s value of MSTR given that it happens. The same for NO, with the chance it doesn’t.

If it happens: YES 0.935 (mid) ÷ P 0.935 = 1.00× spot ≈ $137
Otherwise: NO 0.0650 ÷ (1 − P) 0.0650 = 1.00× spot ≈ $137

How far to trust it

Chance (P): 93.5% from Polymarket, as of 17s ago. It is a reference: not traded here, settles nothing here. Their book: bid 92.0%, ask 95.0% (3.0 points wide).
Leg prices: The midpoint of this book: YES 0.935 MSTR (bid 0.890, ask 0.980, 9.0 points wide); NO is the rest of one share.
Spot: $137 from the token’s on-chain pool price times Chainlink’s BTC/USD. It only turns the multiples into dollars.
Updated: 17s ago; refreshed every 20 seconds.
Sensitivity: One point of P moves the “otherwise” value by about 15%.

Rules

Settled on UMA ↗

Microstrategy delisted from MSCI index by December 31?

Full rules and settlement

This market will resolve to “Yes” if MicroStrategy is removed from either the MSCI World Index or the MSCI USA Index at any point by December 31, 2026, 11:59 PM ET. Otherwise, it will resolve to “No.” If MicroStrategy is transferred between indexes (e.g., from MSCI World to another MSCI index), that will also count as a removal for the purposes of this market. An official MSCI announcement of removal or transfer will be sufficient for a ‘Yes’ resolution. The resolution source will be official MSCI communication or a consensus of credible reporting.

Contracts and settlement

This question mirrors the Polymarket market "Microstrategy delisted from MSCI index by December 31?" (https://polymarket.com/event/will-microstrategy-be-delisted-from-the-msci-index-by-march-31, Polygon conditionId 0x1f2f8b7de407213b780d16021977b90cea238c9787d07957133569ac83aa0b3b). Its rules are copied verbatim below as published on 2026-09-30; wherever they say "this market", they mean that Polymarket market.

Nobody can edit the frozen words, including Polymarket. The proposer posts a 500 USDC bond plus UMA’s 250 USDC final fee, both returned if their answer stands, on UMA, the oracle Polymarket also uses, through the same adapter contract Polymarket uses, unmodified. A first dispute re-opens the question; a second goes to UMA’s token-holder vote, and whoever was wrong loses their bond: if you hold a leg a wrong answer would hurt, the dispute window is yours.

Emergency override: the adapter’s admin can flag a question and resolve it manually one hour later, with any payout, over whatever UMA said. That power exists in Polymarket’s adapter as deployed (0x006B05…19e665 (opens in a new tab)).

Polymarket’s own result has no effect here. The two are expected to agree because the wording is the same.

Settles through Polymarket's UMA adapter (unmodified) on UMA's Optimistic Oracle. The question text is frozen on chain and copies Polymarket's rules word for word. After the deadline anyone can propose the answer with a 500 USDC bond plus UMA's 250 USDC final fee (both returned if the answer stands); undisputed for 24h it settles, disputed it goes to UMA's token-holder vote. Polymarket's own result has no effect here. The adapter's admin can flag an unresolved question and resolve it manually one hour later — an emergency override over UMA's answer, disclosed because it exists.
