The money

From $300B to $1.25T since March 2025.

November 2026

November 2026 round

$1.25T valuation
$11B raised · led by SoftBank, MGX

First close of a round that set out to raise more than $30B and was scaled back after a sell-off in AI stocks. Reported at a $1.25T valuation; CFO Sarah Friar described it as a pre-money figure and the round as still open, with up to about $20B in total expected.

March 2026

March 2026 round

$852B valuation
$122B raised · led by SoftBank, Andreessen Horowitz

Co-led by SoftBank with a16z, D.E. Shaw Ventures, MGX, TPG, and T. Rowe Price-advised accounts. Strategic partners Amazon ($50B), NVIDIA ($30B), and Microsoft also participated. The largest single private financing on record; at least $35B of the headline figure is contingent.

October 2025

Recapitalization & tender

$500B valuation

Converted the for-profit into OpenAI Group PBC, controlled by the nonprofit OpenAI Foundation (which holds equity worth ~$130B). An employee tender offer let staff sell shares at a ~$500B valuation. Microsoft's stake was aligned to the new PBC structure at roughly 27%.

Common questions

OpenAI stock, answered.

Is OpenAI publicly traded? Can I buy OpenAI stock?

Not yet. OpenAI is a private company. It confidentially filed a draft S-1 with the SEC on June 8, 2026, an early step toward an IPO, but no shares trade publicly and no ticker, price, or date has been set. Today you can only get exposure indirectly, via public proxies like Microsoft (MSFT) and Nvidia (NVDA), or through accredited-investor secondary markets.

What is OpenAI's valuation?

OpenAI was valued at $1.25T pre-money in its latest funding round, which first closed on November 6, 2026. That puts it back ahead of rival Anthropic, which had overtaken it in May 2026.

What is OpenAI's market cap?

OpenAI is private, so it has no public market cap. That figure only exists once a company's shares trade on an exchange. The closest equivalent is the valuation set in its most recent funding round, $1.25T pre-money in November 2026. Treat it as the nearest available proxy rather than a true market capitalization; a real market cap will only exist after an IPO.

How much revenue does OpenAI make?

OpenAI's annualized revenue run-rate was roughly $70B (end Sep 2026), up from about $40B (end Jul 2026), driven by ChatGPT subscriptions, enterprise deals, and API usage.

When will OpenAI IPO?

No date has been set. A confidential S-1 was filed June 8, 2026. In September 2026 Sam Altman ruled out a listing that year, and in November OpenAI's president Greg Brockman said the company could be ready for an IPO in 2027. Watch for the public S-1, which will reveal audited financials, risk factors, and governance terms.

Is there a ChatGPT stock?

No. ChatGPT is a product of OpenAI, and OpenAI is private, so there is no ChatGPT stock and no ticker. The nearest thing to a share price is what investors paid in OpenAI's own funding rounds: $992.06 a share in November 2026.
