New York, 15 September 2026 — EBM Newsdesk Analysis —Brad Adams
Anthropic, the maker of the Claude AI models, is working toward a public listing that bankers and investors are discussing at a valuation of roughly $2 trillion. If that figure holds when the company actually prices shares — expected as soon as October — it would surpass SpaceX’s $1.77 trillion Nasdaq debut from June as the largest initial public offering in history, and it would do so by more than $200bn. For comparison, Saudi Aramco’s 2019 listing, the previous benchmark for scale, priced at roughly $1.7 trillion. A chart comparing the two AI-era listings against Aramco, Alibaba, Facebook and Visa makes the shift look almost absurd: the newest entrants now dwarf the companies that used to define what “largest IPO ever” meant.
The Numbers Behind the Number
Anthropic’s last confirmed private valuation was $965 billion, set in a $65 billion Series H round in May 2026 led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital, with participation from Baillie Gifford, Blackstone, Brookfield and other institutional names. A $2 trillion IPO valuation would represent roughly a doubling of that price in under five months — the kind of step-up that normally invites scepticism, except that Anthropic’s revenue has been accelerating at a pace that makes the multiple look less unreasonable than it first appears. Annualised revenue reportedly crossed $47 billion in May, then $65 billion by the end of July, and some investor projections now put annualised revenue at $100-120 billion by December — more than tenfold growth from the May figure inside a single year. On a rough calculation, $2 trillion against $65 billion in annualised revenue works out to roughly 31 times revenue, a genuinely aggressive multiple even by the standards of the current AI cycle, but one investors appear willing to underwrite given the trajectory.

SubscribeThe company confidentially filed a draft S-1 registration statement with the SEC on 1 June 2026, and is reportedly working with Morgan Stanley, Goldman Sachs and JPMorgan on the listing. None of the specific figures — the $2 trillion valuation, the October timing, the size of the raise — have been confirmed by Anthropic itself; every number in circulation is attributed to investor expectations and banker discussions reported by the Financial Times, Bloomberg and Fortune, not company guidance. The Wall Street Journal has reported the offering could raise up to $100 billion.
Part of a Wider Pattern, Not an Isolated Event
EBM covered Anthropic’s IPO filing in June as part of a broader wave that also includes SpaceX and OpenAI, drawing explicit parallels to the dot-com era’s habit of front-loading value creation into private rounds before ordinary investors ever get a chance to buy in. That pattern has already played out once this year: SpaceX priced at $135 a share for a $1.77 trillion valuation in June, raising $86 billion in the largest flotation on record at the time — before a subsequent sell-off wiped roughly $1 trillion from the value of Musk’s stake, a stumble EBM described at the time as the clearest test yet of whether public markets would keep paying “imagination prices” for unproven AI economics. OpenAI, meanwhile, filed its own IPO paperwork in June targeting a $1 trillion valuation despite reporting that it loses money on every dollar of revenue it earns — a contrast that puts Anthropic’s reported move toward operating profitability in useful context. Three AI-adjacent companies, each at or above $1 trillion, all converging on public markets within months of each other, is not something capital markets have absorbed at this scale before.
The Genuinely Distinctive Part of Anthropic’s Case
What separates Anthropic’s pitch from SpaceX’s or OpenAI’s is where its revenue actually comes from. Anthropic has built its commercial base disproportionately around enterprise customers who value reliability, regulatory compliance and data security, rather than chasing the consumer scale race OpenAI has prioritised with ChatGPT’s roughly 900 million weekly users — a strategy EBM’s own analysis of OpenAI’s business model noted converts far less reliably into paying revenue than Anthropic’s enterprise contracts do. Preliminary figures reported by Bloomberg suggest Anthropic posted positive adjusted operating income for the first time recently, reversing a roughly $5.6 billion loss in 2024 — a genuinely rare data point in an AI sector still dominated by companies burning cash to buy growth.
My Read: A $2 trillion number is easy to treat as a headline rather than an argument, so it’s worth being precise about what would actually justify it: not the AI narrative in general, but whether $100-120 billion in annualised revenue by December is real rather than aspirational, and whether enterprise customers keep renewing at the rate that’s gotten Anthropic here. SpaceX’s post-IPO stumble is the closest available precedent, and it wiped out a trillion dollars of paper value once public markets got to test a mega-valuation against actual quarterly results rather than banker projections. Anthropic’s case is more grounded than SpaceX’s AI-infrastructure story or OpenAI’s user-growth story, because enterprise revenue is a harder number to dress up than a total addressable market slide. Whether “more grounded” survives contact with a live stock price is precisely what October will test.
