Anthropic Investors Target $2 Trillion at October IPO — Would Be Largest Ever

Anthropic’s October IPO is shaping up to be the largest in history. Half a dozen investors in the company expect it to price at $2 trillion or more when it lists on Nasdaq, a figure that would surpass SpaceX’s $1.77 trillion float in June and vault past every previous IPO on record.

The company filed its confidential S-1 with the SEC in June at a $965 billion post-money valuation. The new investor consensus, reported first by the Financial Times on August 13, implies pricing more than double that figure at the actual offering.

Revenue Is the Driver

The valuation math rests on a revenue trajectory few companies have managed at this scale. Anthropic’s annualized revenue was $47 billion in May. Investors now expect it to land between $100 billion and $120 billion before year end — tenfold growth within the calendar year.

One investor framed the multiple math bluntly: a company expanding at 800% annually commands at the very low end of reasonable expectations a 30x revenue multiple, implying a $3 trillion valuation. Palantir and Nebius — AI-adjacent companies in entirely different weight classes — currently trade at approximately 55x trailing sales. By that comparator, the $2 trillion figure would be the conservative case.

Morgan Stanley, Goldman Sachs, and JPMorgan are leading the offering. Anthropic entered a quiet period after the June S-1 filing and declined to comment. Senior executives have not fixed a target valuation internally, according to the Financial Times.

The SpaceX Comparison

SpaceX went public in June at $1.77 trillion, itself a record. Anthropic at $2 trillion would clear that by roughly 13%. At $3 trillion it would exceed SpaceX by 70%.

The IPO will be the first from one of the four top-tier foundation model labs. OpenAI remains private, Google DeepMind is a subsidiary, and xAI is controlled by Elon Musk. Anthropic’s listing will set the public market reference point for AI lab valuations — a figure that will reprice every private round currently being negotiated across the sector.

What Changes at $2 Trillion

At that valuation, Anthropic becomes one of the ten most valuable public companies in the world at listing. The float also accelerates the timeline for every other AI lab considering public markets: a clean $2T+ comp with strong revenue growth and visible margin trajectory removes a significant piece of uncertainty.

The $100-120 billion revenue run rate — if it holds to year end — would give Anthropic a revenue base comparable to where Microsoft was in 2019, reached in roughly three years of commercial operation. The growth rate has no close historical parallel in enterprise software at this scale.
