SAN FRANCISCO, Sept. 3 (Xinhua) -- U.S. AI startup Anthropic has raised 13 billion U.S. dollars led by ICONIQ at a post-money valuation of 183 billion dollars.

The Series F fundraising was co-led by Fidelity Management & Research Company and Lightspeed Venture Partners, according to the company.

The company said the investment will be used to expand its capacity to meet growing enterprise demand, deepen safety research, and support international expansion.

"We are seeing exponential growth in demand across our entire customer base," Anthropic CFO Krishna Rao said.

In March, Anthropic raised 3.5 billion dollars in Series E at a 61.5-billion-dollar post-money valuation.

Anthropic has seen rapid growth since the launch of AI model Claude in March 2023, the company said. ■
