OpenAI and Anthropic have both filed confidential paperwork with the U.S. Securities and Exchange Commission (SEC) for massive initial public offerings (IPOs). This rapid sequence of filings marks the start of a historic public market showdown, as the world’s leading generative AI developers race to Wall Street.
Key Valuation and Filing Metrics
The filings place both companies at unprecedented, near-trillion-dollar valuations for debut listings.
- Anthropic: Confidentially submitted its draft S-1 on June 1, 2026. The company is seeking a public market valuation of $965 billion, riding the momentum of an explosive revenue run-rate that grew from $9 billion to $47 billion within the past year.
- OpenAI: Followed closely by announcing its confidential S-1 submission on June 8, 2026. It is targeting a debut valuation approaching $852 billion to over $1 trillion. This follows a massive $122 billion corporate restructuring and funding round completed earlier this year.
Why the Shift to Public Markets Now?
- Astronomical Compute Costs: Training frontier AI foundation models requires immense financial capital. For context, OpenAI’s infrastructure and compute costs are estimated to exceed $100 billion annually, requiring continuous, massive influxes of funding.
- Overcoming Legal Overhangs: OpenAI’s path was cleared following a crucial legal victory in May 2026, when a U.S. jury unanimously dismissed a high-profile lawsuit brought by early backer Elon Musk.
- The SpaceX Factor: The market momentum is being further accelerated by Elon Musk's SpaceX, which priced its own record-breaking $75 billion public offering concurrently, creating a combined $3.6 trillion IPO pipeline that is crowding out other tech sectors.
Material Risks and Roadblocks
While enthusiasm is high, both companies present unique "reality checks" for prospective public investors:
- Severe Financial Burn: Despite generating $13.1 billion in 2025 revenue, OpenAI expects a $14 billion net loss in 2026 and does not anticipate turning a profit until at least 2029 or 2030. Anthropic, however, has signaled to investors that its strong enterprise adoption could yield profitability sooner.
- Unresolved Litigation: OpenAI's eventual public prospectus will have to disclose hundreds of millions to billions of dollars in potential risk exposure from ongoing copyright and fair-use lawsuits, including its active battle with the New York Times.
Expected Timeline
Because these are confidential filings, the public cannot yet view the companies' exact financial ledgers or specific share pricing. Under standard SEC review guidelines, initial trading could begin as early as September or October 2026, though OpenAI executives have stated they may wait until 2027 to officially list, depending on market volatility.
