OpenAI Is Filing to IPO. The Numbers Say It Shouldn’t Have To.
OpenAI is preparing to file a confidential IPO prospectus as soon as Friday, according to four people familiar with the matter, putting the artificial intelligence company on a path toward a public market debut that will test whether investors have appetite for a $850 billion entity that has never turned a profit and shows no credible near-term path to doing so.

The filing sets up one of the most unusual public offerings in recent memory: a company valued at more than Goldman Sachs, burning through roughly $3.30 for every dollar of revenue it collects, and controlled by a nonprofit foundation that holds a 26 percent equity stake but retains ultimate authority over the for-profit entity. Substack Reuters Public shareholders who buy in will own a piece of the revenue and the losses, but not the mission.
The governance structure is easier to understand by contrast. SpaceX, which filed its own S-1 with the SEC on the same day OpenAI's plans were reported, uses a dual-class share structure: Class A shares carry one vote each, Class B shares carry ten votes each. Elon Musk controls enough Class B shares to hold a majority of voting power and elect a majority of the board outright. SpaceX will be a "controlled company" under Nasdaq rules, exempting it from certain board independence requirements. SEC Axios
OpenAI's structure works differently. It restructured to a public benefit corporation in 2025, a legal form also used by Anthropic and x.ai. Under that arrangement, the OpenAI Foundation holds 26 percent of the equity but the nonprofit board retains decision-making authority over the mission, including the ability to override commercial decisions that conflict with it. Minority public shareholders cannot remove the board. There is no equivalent mechanism in standard corporate law. OpenAI Reuters
The practical implication is concrete. If the nonprofit board decided that a product feature or commercial decision conflicted with the mission, it could halt that decision. Shareholders who believe the same decision would maximize shareholder value have no formal recourse. In a standard corporation, a board that prioritized stakeholders over shareholders would face removal. At OpenAI, that board answers to a nonprofit mission, not to equity.
OpenAI generated approximately $13.1 billion in revenue in 2025, according to figures reported by CNBC. It burned roughly $22 billion. Projected losses for 2026 are expected to reach $14 billion, roughly triple this year's rate, according to people briefed on the company's internal outlook. CNBC The company has raised more than $180 billion from investors since its founding. CNBC Cumulative losses through 2029 are estimated at $44 billion before a potential path to profitability, according to independent analysis by FutureSearch. FutureSearch
The offering is being led by Goldman Sachs and Morgan Stanley, according to people familiar with the banks' roles. The goal is to be ready to go public as early as September 2026, though the timing remains fluid and a confidential filing does not guarantee the IPO proceeds on that schedule. WSJ
CFO Sarah Friar said in April that it is good hygiene for a company of OpenAI's size to look and feel like a public company. That is a lower bar than being one in any meaningful governance sense. CNBC
The competitive backdrop adds pressure. Anthropic is currently in talks to raise money at a $900 billion valuation, which would bring it within striking distance of OpenAI's private market valuation, according to people familiar with those discussions. Anthropic topped $30 billion in annualized revenue in April 2026, Reuters reported separately. CNBC OpenAI's comparable figure is estimated at approximately $20 billion annualized at the end of 2025. Reuters The gap is narrowing faster than OpenAI's burn rate can plausibly be justified by growth alone.
Both OpenAI and SpaceX are targeting a public debut window between Labor Day and Thanksgiving 2026, according to Axios. Axios SpaceX's filing is publicly available on SEC.gov. OpenAI's prospectus will remain confidential until the SEC begins its formal review, at which point the full financial picture will become public for the first time.
What the numbers show then will determine whether this story is a growth company's maturation or a cash-intensive gamble that asks public markets to underwrite losses that private investors have so far been willing to carry. If OpenAI stumbles post-IPO, the repricing will not be contained to one company. Its S-1 will become the valuation benchmark for every AI company chasing it to market, and the entire sector will feel the weight of its numbers.
