Anthropic investors expect the company to go public in October at a valuation of $2 trillion or more, a figure that would eclipse SpaceX's $1.77 trillion June debut and make the listing the largest IPO in history. Half a dozen backers told the Financial Times that rapidly climbing revenue at the Claude maker justifies more than doubling its current $965 billion mark. The five-year-old company filed paperwork with the Securities and Exchange Commission in June, putting Dario Amodei's lab in a quiet period ahead of the autumn float.
The bull case rests on one number: investors expect Anthropic's annualized revenue to hit $100 billion to $120 billion by the end of 2026, using the startup's preferred measure of inferring full-year sales from recent performance. That would represent more than a 10x jump over the course of the year, from the $47 billion annualized figure the company disclosed in May. Venture capitalists, sovereign wealth funds and other institutional investors have already poured just under $100 billion into Anthropic in 2026.
Anthropic lacks a publicly listed US peer to anchor the valuation. Data intelligence group Palantir and cloud company Nebius, both viewed as AI beneficiaries, have traded this year at roughly 55 times revenue. Applying even a fraction of that multiple to Anthropic's projected run rate is what gets investors to $2 trillion — and some argue the ceiling is higher.
Key facts
- 01Anthropic investors expect an October 2026 IPO at a valuation of $2 trillion or more, which would surpass SpaceX's $1.77 trillion June listing.
- 02Backers project annualized revenue of $100B–$120B by end of 2026, up more than 10x over the year, implying an 800% growth rate.
- 03Anthropic's annualized revenue surpassed $47B in May, when its valuation leapfrogged OpenAI to reach $965B.
- 04Investors have poured just under $100B into Anthropic in 2026, ahead of a June SEC filing that started the quiet period.
- 05Anthropic's top model costs 2.5x more to use than OpenAI's flagship, and Ramp analysts say customers are 'hitting their limit on AI spend.'
Investors say senior Anthropic executives have not fixed a valuation target for the IPO, even in private conversations, leaving backers to run their own models. A $2 trillion mark would surpass OpenAI in public-market terms and cap a run in which Anthropic's private valuation leapfrogged its larger rival for the first time in May.
The company has gained ground on OpenAI and Google by shipping models that have outperformed competitors on business tasks, with a sales motion aimed squarely at enterprise customers. Anthropic increased its market share among US businesses last month, according to payments group Ramp.
The path is not clean. Anthropic remains in active litigation against the US Department of Defense, which labeled the company a supply-chain risk earlier this year. In June, the Commerce Department hit Anthropic with export controls that forced it to briefly pull its leading models, Fable 5 and Mythos 5 — an episode that spooked some enterprise customers and contributed to a slowdown in overall revenue growth that month, according to two investors familiar with the numbers. Growth has since rebounded.
Pricing is the other pressure point. Anthropic's flagship model costs more than 2.5 times as much to use as OpenAI's, according to Artificial Analysis, and Chinese open-weight alternatives run at a fraction of both. Ramp analysts found that businesses are 'hitting their limit on AI spend' and increasingly reaching for cheaper, less powerful models to keep budgets in check.
None of that has dented investor enthusiasm heading into the filing. Backers point to Anthropic's lead on model performance and its enterprise positioning as the durable moat.
A $2 trillion IPO would reset the reference points for every private AI valuation still on the board. If Anthropic prices anywhere near that mark, OpenAI's next funding round becomes a very different negotiation, and the 55x-revenue multiples that public AI-adjacent names have been trading at start looking less like a bubble signal and more like the new baseline. The risk, as Ramp's data hints, is that the customer bill for all this compute is starting to bite — and public markets, unlike private ones, will reprice the moment growth slows.
