Anthropic has raised $13 billion in a new Series F funding round, underscoring investor appetite for artificial intelligence companies even as competition intensifies across the sector. The deal values the San Francisco-based startup at $150 billion on a post-money basis, according to Reuters.

The fundraising comes as demand for Anthropic’s AI models continues to grow, helping the company attract major backing at one of the highest valuations in the industry. The round adds substantial capital as the firm expands its technology, products, and infrastructure to keep pace with rivals.

Anthropic’s latest financing also highlights how quickly the AI market has matured into a major battleground for funding, talent, and enterprise customers. The company is now among the most highly valued private AI firms, reflecting strong confidence from investors in the long-term commercial potential of generative AI.
