SpaceX hits Nasdaq in 3 days. Anthropic filed last week. Now OpenAI has entered the race. Three companies worth a combined $3.5 trillion — and none of them are publicly tradeable yet.

The sequence of events over the past two weeks is unlike anything in IPO history:
Anthropic submitted its confidential S-1 filing on June 1, 2026, at a valuation of $965 billion. OpenAI followed exactly one week later on June 8, filing its own confidential S-1 at an $852 billion post-money valuation. SpaceX, having already kicked off its investor roadshow, is preparing to sell shares at $135 apiece for a total raise of $75 billion at a valuation of around $1.77 trillion — the largest IPO in history.
Investment bankers have advised both OpenAI and Anthropic that an early mover advantage is at stake. The first to list would set the terms for how investors categorize the AI sector and gain access to enormous amounts of capital looking for an entry point into the industry.
The AI IPO race is no longer a rumor. It is a calendar event.
OpenAI closed a $122 billion funding round on March 31, 2026, pushing its post-money valuation to $852 billion. Goldman Sachs and Morgan Stanley are leading the deal, with a September 2026 debut reported but not confirmed by the company.
ChatGPT now has 900 million weekly active users — a scale that dwarfs most consumer internet platforms ever built.
But the financial picture is more complicated than the user numbers suggest.
For full-year 2025, OpenAI generated $13.1 billion in revenue but burned through approximately $22 billion to do it — a net loss of around $9 billion. Internal projections suggest a $14 billion operating loss for 2026. OpenAI is losing $1.22 for every $1 of revenue earned.
The company needs an estimated $207 billion in additional capital through 2030 just to honor its existing compute commitments. Public markets are the only pool deep enough to fund that runway.
This is not a victory lap IPO. It is a capital necessity.
Here is the detail that changes the competitive narrative significantly.
Anthropic led global LLM revenue share at 31.4% in Q1 2026, narrowly edging out OpenAI's 29%. Anthropic is projecting $10.9 billion in Q2 2026 revenue — more than double its Q1 figure of $4.8 billion — and expects its first profitable quarter ever, projecting $559 million in operating income.
Anthropic is about to demonstrate something OpenAI has not: the ability to generate more cash than it spends.
Two companies. Similar valuations. Radically different financial trajectories heading into their public debuts. For investors trying to allocate between them, that distinction will matter enormously once S-1 filings become public.

OpenAI acknowledged the submission in a statement: "We recently submitted a confidential S-1. We expect it to leak, so we're just announcing it." The company added that the filing should not be read as a sign that a listing is near, stating it "has not decided on timing yet" and may stay private for some time while retaining the option to list sooner if conditions allow.
OpenAI CEO Sam Altman framed the moment as the beginning of a third phase for the company — one focused on making advanced AI affordable and accessible at scale rather than concentrating capability among a small number of institutions.
Reading between the lines: OpenAI is filing now to keep options open, not because it is ready to open its books to full public scrutiny. The confidential track gives it flexibility. The $207 billion capital gap gives it urgency.
The scale of what is converging right now is worth pausing on.
SpaceX lists Thursday. Anthropic targets October. OpenAI targets September. Combined, these three companies represent approximately $3.5 trillion in private market valuation — all moving toward public markets within months of each other.
The prospect of two of the world's most valuable AI companies becoming publicly traded within months of each other is unprecedented. It will force both companies into a level of financial transparency that the AI industry has largely avoided up to this point.
For retail investors in SEA, the window to access any of these companies at pre-public valuations has already closed. What remains is the question of how public market pricing will land — and whether the institutions who built these positions over years will find the exit they have been waiting for.
