Anthropic Secures $13 Billion Series F, Soaring to $183 Billion Valuation

Anthropic, the AI powerhouse, has closed a staggering $13 billion Series F, catapulting its post-money valuation to $183 billion, solid proof that global investors are doubling down on enterprise AI’s future. This influx, co-led by Iconiq Capital, Fidelity, and Lightspeed, isn’t just cash; it’s a high-voltage endorsement from asset managers, VCs, and sovereign funds, including Altimeter, BlackRock, and Qatar Investment Authority.

Surging demand isn’t just hype. CFO Krishna Rao points to exponential customer growth with enterprise adoption driving Anthropic’s annual recurring revenue up fivefold from $1 billion to $5 billion in 2025 alone. In just the past year, large accounts delivering $100,000 plus in annual spend have exploded by nearly 7x, pushing the customer tally to 300,000.

Claude Code, the developer-centric coding product, is at the heart of the action. Revenue from Claude Code has crossed $500 million in run rate, lifted by a tenfold usage surge in the last quarter. The momentum hasn’t gone unnoticed. What began as rumors of a $5 billion round at a $170 billion valuation ended in a mega raise, exceeding expectations and locking in one of the largest checks the sector has seen.

Yet scaling at this pace has its own challenges. CEO Dario Amodei has been frank about the cost of competition, especially with OpenAI and Cursor on the move. “It’s difficult to run a business by excluding bad people from investing,” Amodei shared in a Wired memo, acknowledging the ethical tension around accepting funds from sovereign wealth sources.

For Anthropic, the fresh war chest is earmarked for ramping up enterprise deals, advancing safety research, and going global—all to build safer, more reliable AI for critical industries. As the funding arms race intensifies, Anthropic’s latest round stands out as a clear signal: the next chapter of AI will be defined by scale, speed, and stakes higher than ever.
