OpenAI’s confidential June 2026 S-1 filing and $852 billion March private valuation anchor trader views, yet CEO Sam Altman’s reported $1 trillion floor and preference for a 2027 debut over a softer 2026 listing create a wide distribution of implied probabilities across the $1.25–2.0 trillion brackets. Revenue run rates above $40 billion and heavy compute spending produce both high-growth multiples and large GAAP losses that markets must price, while SpaceX’s post-IPO volatility and Anthropic’s parallel path add caution on execution risk and capital-market appetite. Upcoming SEC review milestones and any new funding or tender data will likely tighten these ranges as listing timing clarifies.

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 confidential June 2026 S-1 filing and $852 billion March private valuation anchor trader views, yet CEO Sam Altman’s reported $1 trillion floor and preference for a 2027 debut over a softer 2026 listing create a wide distribution of implied probabilities across the $1.25–2.0 trillion brackets.
