Anthropic just closed a massive $13 billion Series F round, pushing its valuation to a staggering $183 billion. The AI startup plans to use the cash to ramp up enterprise adoption, expand globally, and boost safety research.
Iconiq led the round alongside Fidelity and Lightspeed Venture Partners. Other investors include heavy hitters like Altimeter, BlackRock, Blackstone, Coatue, and sovereign wealth funds such as Qatar Investment Authority and Ontario Teachers’ Pension Plan.
The funding comes hot on the heels of Anthropic’s explosive growth. Annual recurring revenue shot from $1 billion to $5 billion in 2025 alone. The company now serves over 300,000 business customers, with large accounts—those paying $100K+ annually—growing nearly 7x in a year. 
Claude Code, Anthropic’s vibe-coding product, is a key growth driver. It’s already raking in $500 million run-rate revenue, with usage multiplying over 10x in just the last quarter.
Anthropic CFO Krishna Rao said in a blog post:
“We are seeing exponential growth in demand across our entire customer base.”
“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 round dwarfs Anthropic’s $3.5 billion Series E at a $61.5 billion valuation just months ago in March 2025. It’s clear the AI race is intensifying.
But CEO Dario Amodei also admitted the fundraising isn’t easy. He told Wired he’s “not thrilled” about taking money from sovereign wealth funds tied to authoritarian regimes but finds it challenging to exclude “bad people” from investing in a scaling AI firm.
