Market context

OpenAI would need a fresh private-market mark at or above the target by 31 December 2026, with Polymarket now pricing that outcome at 6% YES on USDC-settled conditional tokens on Polygon. In practical terms, traders are buying a claim that the Nasdaq Private Market print, published on its own lagged timetable, will show a higher valuation at some point before year-end rather than relying on any headline funding rumour or secondary chatter.

The obvious reference point is the March 2026 funding update, when OpenAI said it had closed $122 billion of committed capital at an $852 billion post-money valuation, according to its own disclosure. That matters because the market has already moved from a large private mark into territory where a further step-up would need either materially stronger revenue evidence, tighter liquidity in employee and investor stock, or another sizeable round on revised terms. Private-company marks can be sticky, and comparable late-stage names often reprice only when a transaction, tender, or formal secondary clearing resets expectations.

For traders, the key catalysts are the cadence of NPM prints, any disclosed tender or financing process, and whether OpenAI comments further on revenue, infrastructure commitments, or governance. Techi reported in May that there was still no confirmed IPO date and that the S-1 questions remained unresolved, while OpenAI’s own March announcement and the company’s April partnership update have been the main hard datapoints so far. Because NPM prices are published for trading days only, a late-year transaction could matter more than a press cycle, and the settlement window may stay open into early January if the relevant business-day data arrive late.

Methodology

We track Will OpenAI's valuation hit 2027 by December 31? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
