Anthropic has raised $13 billion in a Series F funding round, boosting its valuation to $183 billion post-money. The round was led by ICONIQ, with significant contributions from Fidelity Management & Research Company and Lightspeed Venture Partners. The funds will support enterprise demand, safety research, and international expansion. This latest valuation more than doubles Anthropic's worth from March 2025, when it was valued at $61.5 billion. The company, known for its Claude AI models, aims to enhance its capacity for large customers and further product development. Anthropic's rapid growth positions it among leading private AI firms, alongside OpenAI and xAI.
