Anthropic's $2 Trillion IPO Would Be the Largest Ever: If the Market Agrees

Anthropic, the five-year-old maker of Claude, is preparing for an initial public offering that its own investors believe could value the company at more than $2 trillion. That would make it the largest IPO in history, bigger than SpaceX's $1.77 trillion listing in June, which currently holds the record.

It would also be the clearest test yet of whether public markets are willing to underwrite the AI boom at the multiples its private backers have been using.

The numbers behind the number

Anthropic filed confidentially with the SEC in June and entered a quiet period, which is why almost everything circulating comes from investors speaking to the press. The picture they paint is extraordinary:

• Last private valuation: $965 billion post-money, reached in May, when it overtook OpenAI for the first time.
• Annualized revenue: roughly $47 billion in May, up from about $9 billion at the end of 2025. By July, reports put the run rate above $65 billion; actual Q2 revenue was reported at $11.6 billion.
• Year-end projection: backers expect $100 billion to $120 billion in annualized revenue by December, more than tenfold growth in a single year.
• Raise target: underwriters have reportedly discussed raising more than $100 billion, led by Morgan Stanley, Goldman Sachs, and JPMorgan.

The bull case is simple arithmetic. If Anthropic grows 800% a year, one investor told the Financial Times, it should trade at at least 30 times revenue, which would imply a $3 trillion company. For comparison, AI-adjacent names like Palantir and Nebius have traded near 55 times sales this year.

The caveat that belongs next to every headline

There is an important distinction hiding inside that growth story. A run rate annualizes the most recent month's sales into a full-year estimate. It is a momentum reading, not money in the bank. Anthropic did not book $47 billion in a year; it was selling at that pace in May.

That distinction matters because a $2 trillion valuation is not really a bet on the company Anthropic is today. It is a bet on the company it might become, one where Claude is embedded in enterprise workflows the way Meta is embedded in advertising budgets, with the pricing power to match.

Three real risks

The path to $2 trillion is not clear, and the skepticism is not only reflexive.

1. Price competition. Anthropic's top model costs more than 2.5 times OpenAI's flagship, according to the analysis firm Artificial Analysis. Chinese open-weight models are cheaper still, and some corporate customers have already shifted to lower-cost alternatives as their AI bills climbed.
2. Government friction. Anthropic has clashed repeatedly with the US government, is litigating the Pentagon's designation of the company as a "supply chain risk," and briefly suspended some flagship model access in June due to Commerce Department export controls, which temporarily slowed revenue growth.
3. Overvaluation risk. Investors are increasingly wary of AI stock valuations generally. Anthropic has no listed US peer to anchor its multiple, which cuts both ways: it can command a premium, or the market can reject the premise.

Not everyone is a skeptic. Cathie Wood has argued that open-weight rivals actually boost revenue at frontier labs rather than erode it, and CNBC's Jim Cramer defended the $2 trillion figure on the grounds that the revenue growth, if it materializes, justifies it.

A litmus test for the whole sector

Anthropic is not the only AI company eyeing the public markets. OpenAI bought back $7 billion in employee stock last week as it ramps up its own listing preparations. Crypto traders have been pricing the Anthropic debut for months through pre-IPO tokens on venues like PreStocks and Binance Wallet.

That makes the October listing a referendum both on one company and on the entire AI capital cycle. If Anthropic floats above $2 trillion and holds, it validates the private-market math that has funded the boom. If it stumbles, the debate over whether AI stocks are overvalued shifts from think pieces to portfolio statements.
