Anthropic, the AI startup behind the Claude family of models, has secured a $13 billion Series F financing at a staggering $183 billion post-money valuation, nearly tripling its worth since March.
Anthropic is backed by Amazon and Google-parent Alphabet.
The company said that the round was led by ICONIQ Capital and co-led by Fidelity and Lightspeed Venture Partners, with institutional heavyweights such as BlackRock, GIC, Qatar Investment Authority, Ontario Teachers’ Pension Plan, and Coatue among the backers.
“We are seeing exponential growth in demand across our entire customer base,” Anthropic Chief Financial Officer Krishna Rao said in a statement. “This financing demonstrates investors’ extraordinary confidence in our financial performance and the strength of their collaboration with us to continue fueling our unprecedented growth.”
The numbers feeding the frenzy
In early 2025, Anthropic’s valuation stood at $61.5 billion following a $3.5 billion Series E round. Since then, the company’s annualized revenue has surged from $1 billion to over $5 billion, attributed to rapidly growing enterprise adoption of Claude.
Claude Code, Anthropic’s developer-focused AI assistant, has become a standout performer, generating more than $500 million in run-rate revenue within just a few months of its May launch. Its usage climbed over tenfold in that time.
The company now services over 300,000 business clients, with accounts contributing over $100,000 in annual revenue, increasing nearly sevenfold.
Why are investors so confident?
Investor enthusiasm remains palpable, pulling in capital from major sovereign wealth funds. The Qatar Investment Authority’s participation signals growing geopolitical attention on AI infrastructure.
Anthropic said it plans to deploy the fresh capital toward three core initiatives: enterprise scaling, AI safety research, and global expansion efforts that reinforce its positioning as a safe and capable alternative to consumer-facing rivals.
How cautious should you be?
Anthropic’s skyrocketing valuation underscores how investor appetite for AI overrides the traditional risk calculus. But as a private company far from IPO, questions around future profitability, regulatory scrutiny, and competitive threats, especially from OpenAI, xAI, and others, loom large.
Despite the injections of capital and growth signals, the sustainability of ultra-high private valuations in the tech space has come under increasing scrutiny. Anthropic now sits among the most valuable private companies globally and faces pressure to deliver on the lofty expectations that such a valuation implies.
Two other major rivals
OpenAI has secured $8.3 billion in new funding at a $300 billion valuation, part of a broader $40 billion financing drive slated for 2025. The company’s annual revenue run rates are reported between $12 billion and $13 billion, with projections potentially reaching $20 billion by year-end.
OpenAI is also exploring a $500 billion valuation via a secondary share sale for current and former employees, signaling investor enthusiasm for liquidity events.
Elon Musk’s AI venture, xAI, merged with his social media company X in an all-stock deal that valued xAI at about $80 billion and X at $33 billion, for a combined enterprise valuation of $113 billion. Earlier, xAI had raised $10 billion in debt and equity financing, underscoring Musk’s aggressive push in AI.
