OpenAI’s IPO valuation market reflects uncertainty around timing and pricing power, with the $1.25T–$1.5T bracket holding a narrow lead at 20.5% implied probability. The company’s March 2026 $852 billion post-money round and August secondary marks near $894 billion set the baseline, while CEO Sam Altman’s insistence on a $1 trillion minimum has shifted expectations toward a 2027 debut after the September 2026 window passed without a listing. Persistent operating losses near $14 billion on a roughly $40 billion annualized revenue run rate, alongside competitive pressure from Anthropic’s earlier IPO path, weigh on multiples. Traders appear to price in revenue acceleration potential against dilution and macro risk appetite, leaving the $1.5T–$2T range tightly contested as key swing factors.

This market will resolve according to the implied equity valuation of OpenAI at its initial public offering (IPO) price.
The IPO valuation is defined as the final IPO price per share multiplied by the total number of shares outstanding on a fully diluted basis, as disclosed in the final prospectus filed with the U.S. Securities and Exchange Commission.
The IPO price will be the final offering price to the public as stated in the final prospectus. Trading prices after listing, including the opening trade, intraday prices, or closing price on the first day of trading, will not be considered.
Indicated or preliminary price ranges, including any ranges disclosed in earlier filings or amendments, will not be considered.
If the calculated valuation falls 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.OpenAI’s IPO valuation market reflects uncertainty around timing and pricing power, with the $1.25T–$1.5T bracket holding a narrow lead at 20.5% implied probability.
