Anthropic raises $13 billion funding round at $183 billion valuation

Artificial intelligence startup Anthropic announced on Tuesday that it has raised $13 billion in a new funding round, pushing its post-money valuation to $183 billion—roughly triple its worth compared with its last raise in March.

The round was led by Iconiq, Fidelity Management & Research Co., and Lightspeed Venture Partners, with additional participation from Altimeter, General Catalyst, and Coatue, the company confirmed.

Investor Confidence in Anthropic’s Growth

Anthropic’s Chief Financial Officer Krishna Rao highlighted the significance of the new investment:

“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 deal underscores surging investor enthusiasm for generative AI, as Anthropic cements itself as a leading competitor to OpenAI.

Rapid Valuation Climb

Anthropic’s valuation has risen steeply since the company unveiled its AI assistant Claude in March 2023. Founded by former OpenAI research executives, including current CEO Dario Amodei, the startup has quickly emerged as a powerhouse in the AI landscape.

Its rival, OpenAI, is preparing a secondary share sale that would value the company at around $500 billion, according to reports in August.

Explosive Revenue Growth

The Amazon-backed firm said its annual run-rate revenue now exceeds $5 billion, up from about $1 billion at the start of 2025. Anthropic also revealed that it serves more than 300,000 business customers worldwide, reflecting surging demand for its enterprise-grade AI services.

Future Plans for New Funding

The company said it intends to deploy the new capital to:

• Advance AI safety research and responsible development.
• Expand enterprise offerings to meet growing demand.
• Accelerate international expansion to strengthen its global footprint.

With this funding milestone, Anthropic solidifies its position as one of the world’s most valuable private AI startups, intensifying its rivalry with OpenAI in a sector attracting billions in investment and reshaping global technology markets.
