Recent private funding at an $852 billion valuation in March 2026, followed by OpenAI’s June confidential IPO filing and an August $7 billion secondary share sale at that level, anchors trader expectations near $1 trillion. Persistent operating losses—exceeding one dollar per revenue dollar in early 2026—and intense competition from Anthropic, recently valued near $965 billion, cap upside while supporting modest premiums in the $1.0–1.5 trillion range that together command over 60% of market-implied probability. Analysts highlight revenue growth from ChatGPT subscriptions and enterprise APIs against demands for clearer paths to profitability and multiples near 30–40x annualized run-rate. Potential public debut timing in late 2026 or 2027 remains a key swing factor influencing final pricing.

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.
