The biggest AI listing in history is almost here. Anthropic, the company behind Claude, is preparing to go public in November 2026 with a target valuation of up to $2 trillion — a number that would make it one of the most valuable companies on the planet on day one. But the leaked numbers behind the IPO tell a wilder story: an $80.7 billion loss, revenue exploding 15x in a year, and a $518 billion bet on AI infrastructure.
Anthropic IPO: Key Dates and Valuation Target
Anthropic confidentially filed a draft S-1 registration statement with the SEC on June 1, 2026, and is now racing toward a public listing in November 2026. The plan is to begin marketing the IPO in the week of November 9, with trading expected to start before Thanksgiving. Goldman Sachs and Morgan Stanley are leading the offering.
The headline number is the valuation: the company is targeting as much as $2 trillion. After its latest financial disclosures, some investors are now discussing a lower figure around $1.5 trillion — still a staggering sum. For context, Anthropic’s Series H round in May 2026 valued it at $965 billion, already ahead of OpenAI’s $852 billion valuation from its March 2026 round.
The $80.7 Billion Loss, Explained
The number grabbing all the headlines is Anthropic’s first-half 2026 net loss of $80.7 billion — up from a $13 billion loss a year earlier. But most of that loss is not cash going out the door.
Roughly $72 billion of it is a non-cash accounting charge reflecting the rising fair value of bonds convertible into Anthropic shares — essentially a paper loss caused by the company’s own surging valuation, not money spent on operations. Actual spending on computing capacity and infrastructure in the first half was about $9 billion, up from $2.3 billion a year earlier.
Revenue Is Exploding — Claude Code Leads the Way
The revenue story is the opposite of the loss story. Anthropic pulled in $16.3 billion in the first half of 2026, up from just $1.1 billion in the same period last year. Revenue more than doubled from Q1 to $11.6 billion in Q2, then jumped another 45% to $16.8 billion in Q3 — with the company reporting adjusted profitability and positive cash flow for the quarter.
The main engine is Claude Code, Anthropic’s AI coding tool, which has become a must-have for developers and enterprises. One risk flagged in the filing: about 25% of revenue comes from just two customers, so losing an anchor client would hurt.
The $518 Billion Compute Bet
Perhaps the most jaw-dropping figure in the filing: Anthropic has committed to spending at least $518 billion over the next decade on cloud services, computing and AI infrastructure — with around 80% of those agreements marked as non-cancellable. That is the cost of staying at the frontier of AI: training and running the next generation of models requires data centers on a scale the industry has never seen.
The filing’s risk section is unusually blunt, warning that advanced models could show self-preserving behavior, produce responses resembling blackmail, and that a major AI incident could cause damages too large to insure. The company has also committed 5% of its IPO shares to a new public benefit fund.
Why This IPO Matters for Everyone
Anthropic’s listing will be the defining market event for the AI industry. A strong debut validates the massive spending on AI infrastructure by every big tech company; a weak one could cool the entire sector. With rival OpenAI expected to pursue its own listing next year, the race between the two AI giants is about to play out in public markets. Either way, the age of trillion-dollar AI companies has arrived.
