Anthropic IPO Targets $2 Trillion Valuation, Doubling Its Last Private Mark in Months
Anthropic investors expect the company's forthcoming initial public offering to command a valuation of at least $2 trillion, with the listing expected in October, according to reports published August 13 (NY Post; PYMNTS).
The $2 trillion figure, if achieved, would more than double the $965 billion post-money valuation Anthropic secured in its Series H round just three months ago. That May 2026 raise brought in $65 billion led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital (Anthropic). The trajectory is steep: in February, the Series G co-led by GIC and Coatue valued Anthropic at $380 billion post-money on a $30 billion raise, with D. E. Shaw Ventures, ICONIQ, and MGX also participating (Anthropic; Reuters). Before that, a $13 billion Series F led by ICONIQ in September 2025 placed the company at $183 billion (Anthropic). In April 2026, secondary-market demand had pushed offers past $800 billion (Bloomberg).
Investors backing the IPO thesis expect Anthropic's annualized revenue to reach $100 billion to $120 billion by the end of 2026 (Anadolu Agency). That revenue projection is the anchor for the valuation ask. A $2 trillion market cap against $120 billion in annualized revenue implies a price-to-sales multiple of roughly 16.7x at the midpoint. Against the low end of $100 billion, the multiple expands to 20x. For context within the AI sector, these are growth-stage multiples that assume sustained, compounding revenue acceleration well beyond the fiscal year.
Anthropic is not entering public markets alone. OpenAI filed for a US IPO in June targeting a valuation of up to $1 trillion, with that listing potentially coming as early as September 2026 (Reuters). Reuters reported in April that at current valuations, SpaceX, OpenAI, and Anthropic would together ask investors for approximately $3 trillion in what the wire service described as the biggest IPO wave in history (Reuters).
The cadence of Anthropic's private rounds compressed dramatically over twelve months. The Series F closed at $183 billion. The Series G, roughly five months later, more than doubled that to $380 billion. The Series H, roughly three months after the Series G, nearly tripled to $965 billion. Now the IPO target reportedly seeks to roughly double that again. Each successive round has closed at a compressed interval and a steeper markup than the last.
The broader question for public-market allocators is whether the revenue trajectory can absorb the valuation trajectory. The $100 billion to $120 billion annualized revenue figure is an investor expectation for year-end 2026, not a reported actual. Anthropic has not publicly disclosed current revenue. The gap between the last verified private valuation ($965 billion in May) and the IPO target ($2 trillion) implies that investors pricing the offering are underwriting meaningful revenue growth between now and October, or accepting a richer multiple than the private rounds commanded.
For portfolio managers and allocators, the Anthropic IPO crystallizes a pricing question the private rounds deferred. Private valuations clear on consensus among a small syndicate. Public markets price on marginal demand from a much broader pool, and that pool includes sellers. The $2 trillion ask will be tested against realized revenue, competitive dynamics with OpenAI's concurrent offering, and the absorption capacity of a market already being asked to digest $3 trillion in AI and space-economy supply in a single window.
None of these valuations have been tested in public trading. The October target and the $2 trillion figure are investor expectations, not confirmed terms. Anthropic has not filed an S-1.
