Anthropic Inches Toward a $1 Trillion IPO as Wall Street Lines Up
Anthropic, the artificial intelligence company behind the Claude family of models, is scheduling investor meetings ahead of what could be the most closely watched public offering in tech history. According to CNBC, Goldman Sachs, Morgan Stanley, and JPMorgan Chase are all involved, with a listing on the Nasdaq or NYSE possible as early as October 2026.
From $61 billion to nearly $1 trillion in just over a year
The speed of Anthropic's valuation climb is hard to overstate. The company was valued at $61.5 billion in March 2025. By May 2026, after closing a $65 billion Series H funding round, that number reached $965 billion, briefly pushing it above rival OpenAI's $852 billion valuation. Since its founding in 2021 by former OpenAI researchers led by Dario Amodei, Anthropic has raised a cumulative total of over $129 billion.
The company confidentially filed its IPO prospectus with the Securities and Exchange Commission on June 1, 2026. No share price or listing date has been set, but secondary markets currently price the implied valuation somewhere between $1.05 trillion and $1.15 trillion. A debut above $1 trillion would make Anthropic one of the largest technology offerings ever.
What is actually driving the numbers
Revenue has moved fast. Anthropic's annualized revenue run rate crossed $47 billion in May 2026, up from a reported $9 billion target for 2025. The company generates income three ways: API access to Claude models through AWS and Google Cloud, Claude Code subscriptions (which has become a standard tool for enterprise developers), and Claude for Work enterprise licenses. Eight of the Fortune 10 are reportedly customers.
That said, Anthropic has not publicly disclosed GAAP profitability. Compute costs remain substantial. Harrison Rolfes, analyst at PitchBook, told CNBC that the number determining everything at the IPO will not be the $965 billion valuation or the $47 billion revenue run rate. It will be gross margin.
The race against OpenAI
Anthropic is on track to beat rival OpenAI to the public markets, which matters if AI enthusiasm softens. Filing confidentially first lets the company advance through SEC review while shielding financials from competitors. OpenAI can now watch how institutional investors respond to audited frontier AI numbers before committing to its own pricing.
SpaceX's $75 billion IPO in June 2026, which valued the company at $1.77 trillion, offers a reference point for investor appetite. That listing and a potential Anthropic IPO together represent what analysts call the most concentrated demand for capital in a single year since the dot-com era. Some analysts warn the combined fundraising could create disruptions in global capital markets.
What investors should watch
Before the IPO closes, a few specifics matter more than the headline valuation. First, the public S-1 filing, which will reveal audited financial statements, governance terms, and the actual ownership structure. Second, gross margin trajectory: if compute costs consume the company before margins improve, the bull case collapses. Third, export control exposure. In June 2026, Anthropic had to disable Claude Fable 5 and Mythos 5 for all customers to comply with a U.S. government order restricting access for foreign nationals. That episode is a reminder that regulatory risk is real and can move fast.
Early investors from rounds at $18 billion, $40 billion, and $61 billion face a 15x to 55x return at a $1 trillion valuation. The selling pressure after lockup expiry, expected in Q1 2027, could be substantial enough to affect share price well before the company's fundamentals are fully established in the public market.
The Anthropic IPO, if it prices at or above a $1 trillion market cap, will mark the first time a pure-play AI company has reached that milestone in public markets. Whether the fundamentals can carry that number is the only question that matters.
