OpenAI Files IPO Application with SEC, Valuation $852 Billion
OpenAI confidentially files S-1 with SEC. Following Anthropic’s IPO announcement, but faces challenges including profitability competition and litigation risks.
OpenAI filed a confidential S-1 form with the U.S. Securities and Exchange Commission (SEC) on June 8, 2026. In an official blog post, the company explained: “We have confidentially submitted an S-1. Expecting leaks, we are announcing it in advance. The timing is undecided, and since there are things we want to do as a private company, it does not mean we will go public immediately.” This comes exactly one week after rival Anthropic announced its IPO plans, drawing industry attention to a wave of public listing preparations by major AI companies.
Background of the IPO Announcement
OpenAI has repeatedly raised massive funds as a private company. In its most recent round, NVIDIA and Amazon invested an additional $122 billion, bringing the valuation to $852 billion. According to a report by The Information, annualized revenue as of the end of February 2026 was $25 billion. However, the company is expected to consume up to $115 billion in funds, including computing resource costs, by 2029, raising persistent questions about profitability.
The company commented, “Having the option to go public allows us to access public markets at the best timing.” While it has no immediate intention to conduct an IPO, it also suggests that it may require funds on a scale that would be difficult to raise while remaining private.
AI Market Competition Widens
Three and a half years after the explosive hit of ChatGPT, competition in the AI market continues to intensify. In particular, many evaluate that Google reversed OpenAI’s lead with the release of Gemini 3 Pro in November 2025, and the leadership in model performance is wavering. Anthropic is also expanding enterprise contracts with its unique approach, and the three companies have entered a chaotic warring states period.
If the company rushes to go public under such competitive circumstances, there is a risk that quarterly earnings pressure could impair the freedom of research and development. OpenAI itself admits that “there are some things that are easier to do as a private company,” making the timing of the IPO an extremely difficult decision.
Litigation Risks and Safety Issues
OpenAI also faces litigation risks. In April 2026, the families of victims of a mass shooting in Tumbler Ridge, Canada, filed a negligence lawsuit against the company, claiming its automated safety system ignored warnings. While the direct causal link between this incident and AI is not clear, it has attracted attention as a case where a lack of AI safety is linked to real-world harm.
The company recently released “Lockdown Mode” as a countermeasure against prompt injection (detailed in another article on this site) and is strengthening its safety efforts. However, such lawsuits could become a significant risk factor during IPO review.
Investor Views Are Divided
Many investors expect OpenAI’s growth potential amid the AI boom. On the other hand, there are voices expressing concerns about the business model, which has no clear path to profitability as of 2026 and requires continued massive capital investment. With major tech companies such as Alphabet (Google’s parent) executing $85 billion in corporate bond issuance, AI investment by big tech is accelerating, and OpenAI needs further capital to continue competing on its own.
Once the S-1 becomes public, OpenAI’s detailed financial situation will be revealed for the first time. How revenue structure, R&D costs, and safety-related costs are accounted for will likely influence future valuations.
Editorial Viewpoint
Short-term Impact OpenAI’s IPO announcement, following Anthropic, could accelerate an IPO wave across the AI industry. If both companies’ S-1 filings are made public within the next three to six months, comparisons of profitability and cost structures will become active, leading to a re-evaluation of AI startup valuations. In particular, the focus will be on how much of OpenAI’s massive R&D spending and computing costs are disclosed.
Long-term Perspective Over a one- to three-year time horizon, the question is whether OpenAI can build a sustainable business model as a public company. The key is how much of the computing resource costs, which cannot be covered by current revenue, can be supplemented by post-IPO fundraising. If monetization prospects remain unclear, there is a risk that shareholder pressure may drag the direction of R&D toward fiscal discipline. For the AI industry as a whole, we anticipate a polarization between big tech companies and independent AI firms, with winners and losers.
Editorial Question Is OpenAI’s IPO a necessary condition for the sustainable growth of an AI company, or merely a short-term fundraising tool? Furthermore, how should the balance be struck between the advantages of remaining private (long-term research, risk-taking) and the discipline of public markets (transparency, profit-seeking)? We will watch to see how much the S-1 disclosures answer these questions.

Frequently Asked Questions
- When is OpenAI's IPO expected to occur?
- The timing is currently undecided. OpenAI has stated that "there are things we want to do as a private company," so it appears unlikely to go public immediately. Since it typically takes several months from confidential S-1 filing to public disclosure, the earliest would be late 2026 or later.
- Is the $852 billion valuation reasonable?
- This corresponds to a price-to-sales ratio of about 34 times the annualized revenue of $25 billion. For a rapidly growing AI company, this can be considered within a reasonable range, but given the massive cost structure and intensifying competition, some point out it may be overvalued. Detailed financial analysis will be possible after the S-1 is disclosed.
- Will OpenAI's IPO affect the quality of ChatGPT?
- In the short term, it is not expected to have an impact. However, as a public company, quarterly earnings reports become mandatory, which may force management decisions biased toward profitability. If R&D spending is compressed, there is a risk of long-term impact on model quality.
