Anthropic’s $65 B Series H Rockets Valuation to $965 B, Leapfrogging OpenAI
A lightning-quick Series H round closed on 28-29 May 2026 injected $65 billion into Anthropic and instantly crowned it the most valuable private AI firm at $965 billion, edging past OpenAI ahead of both companies’ anticipated IPOs.
Focusing Facts
- Round size: $65 billion (Series H) led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia; each anchor invested >$2 billion.
- Post-money valuation: $965 billion versus OpenAI’s $852 billion valuation from March 2026.
- Anthropic reported a $47 billion annualized revenue run rate in May 2026 and signaled its first operating profit for the June quarter.
Context
Hyper-capitalised technology sprints are not new—think of the 1860s U.S. railroad land grants or the 1999 dot-com ‘megaround’ for AOL—but the velocity here is record-setting: a five-year-old firm drawing almost 10 % of a trillion dollars in a single private raise. This reflects two deeper currents: (1) compute-hungry foundation models have created a capital-infrastructure loop where cloud oligopolies (Amazon, Google, Microsoft) both fund and sell to the labs, and (2) private capital markets now routinely match or exceed public-market depth, compressing the timeline from garage to global systemically-important entity. Whether this moment matters in a century hinges on if general-purpose AI proves analogous to electricity (1900s) or the airship (1930s); either way, the concentration of capital, talent, and compute into a handful of actors marks a structural shift that regulators and historians will read as the starting gun of the ‘AI corporate era.’
Perspectives
Bullish investor-focused media
Nasdaq Stock Market / The Economic Times — Cast the near-trillion-dollar valuation as spectacular news for investors, arguing that Anthropic’s growth and its ties to Amazon and Alphabet signal lucrative upside and a justifiable sales multiple. Because these outlets cater to retail investors and carry stock-picking services or market data, they have an incentive to hype potential winners, downplaying execution or regulatory risks that could hurt the narrative.
Skeptical financial analysis outlets
Investing.com — Acknowledge the eye-popping valuation but warn that aggressive accounting, huge infrastructure liabilities and unresolved legal disputes could leave late-stage investors exposed when the IPO arrives. Positioning as the ‘voice of caution’ helps differentiate the publication and drive readership from contrarian investors, so the piece may emphasise downside scenarios more heavily than its single-source nature justifies.
International general news agencies
CNA, The Times of India, WION — Report the funding as a landmark that vaults Anthropic ahead of OpenAI and frames the story as an escalating global AI race, spotlighting enterprise focus and safety rhetoric from the company. Dependent on company statements and wire copy, these reports add little independent analysis, so they risk echoing Anthropic’s self-promotion and sensationalising the ‘race’ without probing valuation fundamentals.
