The $965 Billion Company That Has Never Owned a Server

Anthropic filed its IPO paperwork Monday. The AI company telling investors it is worth $965 billion has never owned a single server.

The San Francisco-based company — which confidentially submitted a draft S-1 to the SEC on June 1, 2026 — is simultaneously a customer of, and a competitor to, Amazon, Google, and SpaceX. That is not a coincidence or a temporary arrangement. It is the architecture of a nearly $1 trillion company built on borrowed infrastructure.

Anthropic has raised $65 billion in Series H funding led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, valuing it at $965 billion post-money — a figure that more than doubled from the $380 billion valuation the company carried just three months earlier in February. That valuation now puts Anthropic within reach of the top tier of the S&P 500, as Al Jazeera reported.

The revenue math behind that number is extraordinary. Anthropic's annualized run rate — a projection of full-year revenue based on a shorter period — was roughly $4 billion in July 2024. The company has told investors it will surpass $50 billion annualized by the end of June 2026, according to Fortune, which would represent more than a twelvefold increase in two years. For the second quarter of 2026 alone, Anthropic expects to post $10.9 billion in revenue, more than doubling from the prior three-month period.

All of it runs on other people's hardware. Anthropic signed agreements with Amazon for up to five gigawatts of new compute capacity, with Google and Broadcom for five gigawatts of next-generation TPU capacity — the custom chips Google designed for AI training — and with SpaceX for access to GPU clusters called Colossus 1 and Colossus 2. Those three companies are also Anthropic's most direct competitors in cloud services, chip design, and satellite applications respectively.

The dependency creates a structural negotiating risk that the S-1 will have to disclose plainly: if Amazon, Google, or SpaceX reprice compute access as their own AI businesses scale, Anthropic's margins have no buffer. The agreements are multi-year, but cloud contracts typically include renegotiation clauses tied to capacity utilization — and Anthropic is, by its own account in the Series H, one of the largest single customers of each of its competitors. That concentration is not a footnote. It is the central vulnerability of the business model.

The legal exposure is not theoretical. The Pentagon has declared Anthropic a supply-chain risk, according to Fortune — a designation typically reserved for foreign adversaries and one that could jeopardize billions in federal contracts the company was counting on as it approaches public markets. Anthropic declined to clarify whether those compute agreements contain exclusivity provisions that would limit its ability to switch providers as technology evolves.

The valuation prices in a company executing perfectly. Reuters reported that Anthropic volunteered to absorb all the disclosure risk first, giving OpenAI a free option to watch how institutional investors react to audited frontier AI financials before setting its own terms. Whether that puts OpenAI in a stronger position, or simply means it learns from Anthropic's missteps before walking the same path, is the question the market is still working through. Analysts who follow frontier AI companies say the S-1 will be the first real test — not of whether the technology works, but of whether the revenue holds when the numbers are audited and the customer concentration is visible.

The capital markets pressure is compounding. In the same 24-hour window as Anthropic's filing, Alphabet announced an $80 billion equity raise for AI infrastructure — $40 billion in an at-the-market program, $30 billion in underwritten offerings, and a $10 billion Berkshire Hathaway deal, per Bloomberg. SpaceX is targeting a $75 billion offering at a $1.75 trillion valuation, and OpenAI has signaled its own public ambitions. Al Jazeera reported that the combined demand from all three will likely create disruptions in capital markets, making early positioning a structural advantage. When three companies collectively seeking more than $200 billion in equity and debt hit the market in the same quarter, the pricing of each one affects the others — and the S-1 disclosures will show who blinks first.

What comes next is a test of whether the public market will assign a premium to a company whose infrastructure is, by necessity, its competitors' infrastructure. The filing will show whether the revenue is durable or concentrated, and whether the Pentagon designation triggers immediate contract renegotiations. Until those numbers surface, the $965 billion figure floats on top of a dependency that no public company has tried to defend at this scale.

The thing to watch is which clause in the S-1 discloses the most about who actually controls the compute.
