Anthropic IPO prospectus reveals $42B loss, $518B spending plans

Anthropic, the AI lab behind Claude, filed a confidential S-1 registration statement with the SEC on June 1, laying the groundwork for what would be the first initial public offering by a frontier AI company. The company recorded a net loss of nearly $42 billion in 2025, roughly five times its $8.3 billion loss in 2024. The cause is straightforward: Anthropic is spending enormous sums on the computing infrastructure required to train and run its AI models.

Revenue is surging, but losses are surging faster

Anthropic’s revenue trajectory has been explosive. The company hit a quarterly run rate of $11.5 billion by Q2 2026, representing a 14-fold increase year-over-year. Its annualized revenue rate is projected to exceed $100 billion by the end of 2026, up from just $787 million the prior year.

Anthropic’s infrastructure commitments are staggering: over $100 billion pledged to AWS across a ten-year span, plus a $15 billion annual agreement with SpaceX running through May 2029. Those two deals alone account for a significant portion of the $518 billion in planned infrastructure spending that the prospectus outlines.

A $2 trillion valuation target

Anthropic is targeting a public listing on Nasdaq as early as mid-October 2026, potentially completing the process before the US midterm elections. The company is aiming for a valuation of approximately $2 trillion. SpaceX’s record-breaking fundraise earlier in 2026 valued Elon Musk’s rocket company at $75 billion. The company’s most recent private round, a $65 billion Series H completed in May 2026, pegged its post-money valuation at $965 billion.

Morgan Stanley, Goldman Sachs, and JPMorgan are among the underwriters steering the offering.

The broader stakes for AI and capital markets

Anthropic’s IPO will serve as a referendum on whether public markets are ready to absorb the financial profile of a frontier AI lab. A successful IPO at or near the $2 trillion target could unlock a wave of AI-related public listings from firms including OpenAI and xAI, which have also raised enormous private rounds.

Going public before the US midterms means Anthropic would enter public markets during a period of potential political uncertainty, where regulatory signals around AI governance could shift quickly depending on electoral outcomes.
