Market context

Polymarket is pricing this contract at 6% yes, with USDC locked on Polygon and the outcome determined by a conditional token that resolves against Nasdaq Private Market’s published NPM Price. That low bid implies traders think a fresh private mark at or above the target is still unlikely before 31 December 2026, even though the market has already seen a sharp repricing of OpenAI’s equity. The contract does not follow public share prices; it follows the NPM private-market valuation, updated on trading days and published the next day at 1:00 pm ET.

The nearest reference point is OpenAI’s own March 2026 funding update, when it said it closed $122 billion of committed capital at an $852 billion post-money valuation. That means the market is already starting from a very high base, so the key question is whether any future secondary trading, tender activity, or new financing can push the NPM print higher again. Comparable private-market names can move in steps rather than smoothly, and prediction markets tend to compress that uncertainty into a low probability until there is a concrete new round or a material change in supply and demand for private shares.

Traders should watch for any further fundraising disclosures, employee liquidity programmes, or secondary transactions that could change the NPM mark, as well as any revisions to OpenAI’s revenue run-rate or financing terms. OpenAI’s recent funding announcement, reported by Bloomberg and published by the company on 31 March, is the main fresh reference point, but the next move will likely depend on whether there is another priced transaction before year-end. Because NPM publishes only on trading days and with a one-day delay, a late-December transaction could still matter for resolution if it appears in the January updates.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
