Anthropic Approaches Trillion-Dollar Valuation After $65B Round

Anthropic has raised a $65 billion Series H at a $965 billion post-money valuation and confidentially filed paperwork for a US IPO, according to Anthropic's own announcement and reporting by Fortune, CNBC, BBC, and TechCrunch. The round, among the largest private financings on record, was co-led by Altimeter, Dragoneer, Greenoaks, and Sequoia, with participation from Coatue, Fidelity, and Blackstone and strategic partners Samsung, SK Hynix, and Micron. CNBC reports run-rate revenue crossed $47 billion, and the valuation now exceeds OpenAI, whose March round closed at $852 billion post-money. Multiple outlets report a listing could come as soon as this fall. Saastr, citing roughly 5,000 employees, estimates about $9.4 million in revenue per employee.
What happened
Anthropic has closed a $65 billion Series H at a $965 billion post-money valuation and confidentially filed draft paperwork for a US initial public offering, according to Anthropic's own announcement and reporting from Fortune, CNBC, BBC, and TechCrunch. By CNBC's account, the valuation moves Anthropic ahead of OpenAI as the most valuable AI startup.
The round
Reporting indicates the financing was co-led by Altimeter, Dragoneer, Greenoaks, and Sequoia, with participation from a broad institutional syndicate including Coatue, D1 Capital, Capital Group, Baillie Gifford, Blackstone, Fidelity, and DST Global. Strategic memory and chip partners Samsung, SK Hynix, and Micron also joined, per the reporting and Anthropic's announcement. At $65 billion, it ranks among the largest single private capital raises on record.
Revenue and scale
CNBC reports Anthropic's run-rate revenue crossed $47 billion, up sharply since its February Series G, driven by enterprise and developer adoption of its Claude models. Saastr, a SaaS-industry blog, estimated roughly $9.4 million of revenue per employee from a workforce of about 5,000 - a figure that illustrates unusual revenue density but originates from third-party calculation rather than company disclosure.
The IPO race
Fortune and TechCrunch report the filing was made confidentially, letting Anthropic begin the listing process without immediately publishing financials, and that a debut could come as soon as this fall. That would position Anthropic ahead of OpenAI, whose most recent private round closed in March at an $852 billion post-money valuation, in a closely watched race to be the first frontier-model lab to list publicly.
Why it matters
A near-trillion-dollar private valuation paired with an IPO filing compresses the timeline historically needed to reach such scale and signals deep investor conviction in frontier-model economics. For enterprise buyers, the capital underwrites continued model development and compute expansion; for public-market investors, an Anthropic listing would create one of the first large-cap pure-play exposures to a frontier AI lab.
Scoring Rationale
A $65 billion round, a near-trillion-dollar valuation, and a confidential IPO filing make Anthropic the most valuable AI startup and mark one of the largest private financings on record. The mix of mega-scale capital, a $47B revenue run rate, and an imminent public listing carries broad significance for AI commercialization and public markets, placing it at the top of the major-development band just short of a technology paradigm shift.
