OpenAI Files Confidential S-1: The Race to a $1 Trillion IPO
OpenAI Files to Go Public
OpenAI filed a confidential S-1 with the SEC on May 22, 2026, setting the stage for what could be the largest technology IPO in history. The filing came just two days after a jury dismissed Elon Musk's lawsuit against the company, clearing the biggest legal obstacle to going public.
Goldman Sachs, Morgan Stanley, and JPMorgan are leading the deal. CEO Sam Altman is targeting a September 2026 listing at a valuation between $852 billion and $1 trillion.
Key Details
| Detail | What We Know |
|---|---|
| Filing Date | May 22, 2026 (confidential S-1) |
| Target Exchange | Expected Nasdaq |
| Target Timing | September 2026 |
| Pre-IPO Valuation | $852B (March 2026 funding round) |
| Target IPO Valuation | $852B – $1T |
| Lead Underwriters | Goldman Sachs, Morgan Stanley, JPMorgan |
Financial Profile
| Metric | Value |
|---|---|
| Monthly Revenue | ~$2B/month |
| 2026 Projected Losses | $(14)B |
| Expected Profitability | ~2030 |
OpenAI is generating massive revenue but remains deeply unprofitable as it invests aggressively in compute infrastructure and model development. The company does not expect to reach profitability until approximately 2030.
The $122 Billion Funding Round
In March 2026, OpenAI closed the largest private funding round in history: $122 billion at an $852 billion post-money valuation.
Lead Investors
- Amazon: $50B
- Nvidia: $30B
- SoftBank: $30B
- Additional participation from existing investors
This round positioned OpenAI as the second most valuable private company in the world, behind only SpaceX (post-xAI merger).
The Musk Lawsuit Resolution
A critical catalyst for the S-1 filing was the May 20, 2026 jury verdict dismissing Elon Musk's lawsuit against OpenAI. Musk had alleged breach of contract and fraud related to OpenAI's transition from nonprofit to for-profit. The dismissal removed the primary legal overhang that had clouded the company's IPO timeline.
The AI IPO Race
OpenAI's filing comes just days after Anthropic submitted its own confidential S-1 (June 1, 2026) at a $965 billion valuation. The two companies are now in a direct race to public markets:
| Company | Filing Date | Pre-IPO Valuation | Target Timing |
|---|---|---|---|
| OpenAI | May 22, 2026 | $852B | September 2026 |
| Anthropic | June 1, 2026 | $965B | October 2026 |
| SpaceX (SPCX) | May 20, 2026 (public S-1) | $1.25T+ | June 2026 |
2026 is shaping up to be the biggest year for tech IPOs since the dot-com era.
What This Means for Secondary Market Holders
- Lock-up terms remain unknown until the full S-1 is published (~15 days before roadshow)
- Secondary market pricing will increasingly converge with expected IPO pricing
- Pre-IPO window is narrowing — the September target gives holders roughly 3 months
- The $14B projected loss and ~2030 profitability timeline may create public market debate around valuation
