OpenAI files confidential IPO prospectus: targeting valuation above one trillion dollars
What it really says
OpenAI is preparing to confidentially file a draft IPO prospectus with the SEC, possibly as early as Friday, May 23, 2026, according to CNBC. The ChatGPT developer is working with Goldman Sachs and Morgan Stanley and targeting a September 2026 public listing at a valuation exceeding one trillion dollars. At its most recent private funding round in March 2026, the company was valued at 852 billion dollars. CEO Sam Altman is pushing for a speedy listing, while CFO Sarah Friar favors a more cautious approach. A confidential filing is a nonpublic SEC submission - the actual S-1 prospectus disclosing finances, risks, and business dependencies becomes public weeks later. The urgency is partly driven by OpenAI's desire to beat rival Anthropic to public markets and the need to coordinate timing with SpaceX's planned June 2026 IPO. The conversion from a nonprofit to a for-profit public benefit corporation has been completed. Microsoft holds 27 percent, the OpenAI Foundation 26 percent. The annualized revenue run rate exceeded 20 billion dollars by late 2025, yet OpenAI expects losses of approximately 14 billion dollars in 2026 alone and does not project profitability until around 2030.
Our assessment
For those concerned about power concentration in the AI industry, this IPO is a double-edged sword. On one hand, going public means more transparency: as a listed company, OpenAI must regularly disclose its finances, risks, and business relationships, providing more insight than the public has had so far. On the other hand, a trillion-dollar valuation cements the enormous market power of a few AI companies. With Microsoft as a 27 percent shareholder, the boundaries between tech giants and AI startups continue to blur. The fact that OpenAI is seeking such a valuation despite 14 billion dollars in projected 2026 losses illustrates market expectations and the risks of a potential AI bubble. The completed conversion from a nonprofit to a for-profit PBC is also noteworthy: the original promise to develop AI for the benefit of all humanity now exists in tension with the return expectations of future shareholders. On the positive side, public markets also bring increased scrutiny from analysts, media, and regulators.
Relevance for Germany
For Germany, the OpenAI IPO has several implications. First, German companies and government agencies using ChatGPT and the OpenAI API will depend on a company whose strategy is increasingly driven by quarterly results and shareholder interests rather than a nonprofit mission. Second, the IPO highlights the transatlantic imbalance in AI development: while European AI companies like Aleph Alpha or Mistral operate with significantly smaller resources, OpenAI is in an entirely different financial league. Third, the trillion-dollar valuation of a loss-making company raises questions for German investors who may view the September OpenAI IPO as an investment opportunity following the SpaceX IPO in June. Germany's BaFin and the EU securities authority ESMA will monitor the process closely, as a potential share price collapse could also impact European markets.
Fact check
The confidential IPO filing is consistently reported by CNBC, Bloomberg, and the Wall Street Journal. Goldman Sachs and Morgan Stanley's roles as advising banks are confirmed by multiple independent sources. The 852 billion dollar valuation from the private funding round is documented, and the trillion-dollar IPO target comes from the Financial Times. The annualized revenue figure of over 20 billion dollars by late 2025 comes from OpenAI's own disclosures. The 14 billion dollar loss projection for 2026 has been reported by multiple financial outlets but cannot be directly verified from OpenAI sources since the company is not yet publicly listed. The PBC conversion is confirmed by OpenAI's own blog post and media reports. The ownership structure (Microsoft 27 percent, Foundation 26 percent) comes from the official restructuring announcement.
