“Will OpenAI raise between $80B and $90B in its IPO?” is a prediction market on Polymarket with two tradeable outcomes, Yes and No. It belongs to the event “How much will OpenAI raise in its IPO?”. The Yes price is the crowd's implied probability that the question resolves Yes; every trade on the public order book moves it.
Trading ended on Aug 9, 2026 and the venue has not yet reported a resolution. The last observed Yes price was 20.8¢ (20.8% implied). The outcome will be settled by the resolution source; until then the state is shown as awaiting resolution, not as resolved.
Vultax observes this market from Polymarket's public order book and data API and keeps its own record: 25 hourly price points from Sep 13, 2026 to Sep 14, 2026 (Yes between 17.9% and 21.3%); 11 loaded holder wallets, the largest ten holding 99.8% of the loaded shares; 52 recent public fills from 18 wallets. Each figure carries its observation time; nothing here is a return forecast.
Public Polymarket market/event context is available; Vultax source-pack coverage is tracked separately.

Nine stops, one per figure on this page. Each stop says what the number is, why it matters, and what it reads right now for this market.
Each outcome trades as a share that pays $1 if it wins and nothing if it loses. Prices are quoted in cents, and Yes plus No add up to about one dollar.
This market will resolve according to the total gross proceeds raised by OpenAI in its initial public offering (IPO) at the time of pricing. The amount raised is defined as the aggregate dollar value of shares sold at the final offering price at the time of IPO pricing, as disclosed in the final prospectus filed with the U.S. Securities and Exchange Commission. Shares sold pursuant to any overallotment option (greenshoe) will not be considered. Secondary sales of existing shares by current shareholders will be included only to the extent that they are part of the IPO offering at pricing and reflected in the total gross proceeds. Private secondary transactions conducted outside of the IPO will not be considered. If the total proceeds fall exactly on a boundary between two ranges, this market will resolve to the higher range. If OpenAI does not complete an IPO by December 31, 2027, 11:59 PM ET, this market will resolve to the lowest bracket. The primary resolution source will be the final prospectus filed with the SEC; however, a consensus of credible reporting may also be used.

The Yes price read as a chance. A share at 21.5¢ means the crowd gives Yes about a 21.5% chance right now. It moves with every trade, so it is a live forecast, not a verdict.
Dollar value of shares that changed hands in the last 24 hours. High volume means the price is being tested by real money; low volume means a few trades can move it.
Dollars resting in the order book, waiting to be traded against. Deep liquidity lets a large order fill near the quoted price; thin liquidity means the price jumps when someone trades size.
The gap between the best bid and the best ask. A tight spread makes entry and exit cheap; a wide spread is a cost paid on every round trip.
The wallets holding the most shares on each side, and how much of the loaded sample the largest ten control. Concentration shows whether a market is a crowd or a handful of large positions.
The public fills, newest first: which wallet bought or sold which outcome, at what price, and when. It is the market's own diary, and every wallet on it links to a trader profile.
Hourly closes of the Yes price. The range shows how sure or split the crowd has been; the move shows which way it has been changing its mind.
Trading stops at the close time. The outcome is then settled by the resolution source named in the rules. A closed market is not resolved until the venue reports it, so the two states are shown separately.
