The OpenAI IPO is the most anticipated stock market listing of the decade. FloatRadar tracks every confirmed signal — filings, valuation, timing and broker access — so you know exactly where the OpenAI IPO stands and how to position yourself before shares start trading. Below is our plain-English summary, updated as new reporting lands.
Current status: Confidential S-1 filed · timing pushed to 2027. The expected listing window is 2027 (CFO guidance). OpenAI has not announced an official IPO date, a price range or a pricing day. A confirmed date only appears once the company makes its registration statement public and begins its investor roadshow, which typically happens two to four weeks before the first day of trading. Join the FloatRadar waitlist and we alert you the moment the OpenAI IPO date is set.
OpenAI's last private valuation was $852B post-money (March 2026), and the stated IPO target is $1T floor stated by Sam Altman. Revenue signal: Reported ~$2B per month during 2026. There is no official OpenAI IPO share price yet — the price per share depends on the final valuation and the number of shares sold, both set by the company and its underwriters on pricing night. Anyone quoting a fixed OpenAI share price today is estimating, not reporting.
Yes — reporting indicates OpenAI submitted a confidential S-1 draft to the SEC. A confidential filing lets a company work through regulator comments privately. The public S-1, which reveals audited financials, risk factors, share structure and the planned stock exchange and ticker, must be published at least 15 days before the roadshow begins. That public filing is the clearest signal that the OpenAI IPO is imminent.
OpenAI stock is not publicly traded today, so you cannot buy it on a normal brokerage app yet. When the OpenAI IPO happens, there are three realistic ways to get shares:
Allocations in hyped listings are scarce and usually go to larger clients first. The FloatRadar waitlist connects investors with brokers that hold allocation access in upcoming IPOs like OpenAI, Anthropic and Revolut.
There is no published minimum yet. In US IPOs, retail platforms often allow small requests, while full-service brokers may require higher account balances to receive allocations. On day one, the minimum is simply the price of one share — or less with brokers that support fractional shares.
Beyond the OpenAI IPO, FloatRadar covers the Anthropic IPO, the Revolut IPO, Databricks, Stripe and other high-profile pre-IPO companies, plus a live calendar of upcoming Nasdaq listings rated on fundamental strength and hype. Every profile includes the expected IPO date, valuation, filing status and a step-by-step guide on how to buy shares.

Every live Nasdaq filing, sortable by hype level or fundamental grade.
The mega-cap names everyone is waiting for — Anthropic, OpenAI and the rest — with in-depth briefings until they reach the filing calendar.
Artificial intelligence
Anthropic has filed confidentially and is being priced above $2 trillion in pre-IPO secondary markets — more than double its last agreed private round. The S-1 is the missing piece.
Artificial intelligence
OpenAI filed confidentially in June 2026, then let the circled September window pass. The CFO now says 2027; Sam Altman called a 2026 listing 'ill-advised'.
Data & AI infrastructure
Databricks has the revenue profile of a listed company and keeps choosing not to be one. Reported timing has ranged from a mid-2026 filing to 2027.
