Anthropic, a leading artificial intelligence firm, has successfully completed a $13 billion Series F funding round.

This investment elevates the company’s post-money valuation to $183 billion.

Funding Allocation and Growth Strategy

The newly acquired capital will be strategically allocated to several key areas.

• Expanding enterprise adoption of its AI solutions.
• Deepening research focused on AI safety.
• Supporting ongoing international expansion efforts.

Investment Leadership and Participants

Iconiq, Fidelity Management & Research Company, and Lightspeed Venture Partners jointly led the funding round.

Notable backers include Altimeter, Baillie Gifford, BlackRock, Blackstone, Coatue, D1 Capital Partners, Insight Partners, Ontario Teachers’ Pension Plan, and the Qatar Investment Authority.

Financial Performance and Customer Growth

“We are experiencing rapid growth in demand from our entire customer base,” stated Krishna Rao, CFO of Anthropic.

“This financing reflects strong investor confidence in our financial performance and collaborative partnerships to sustain our exceptional growth trajectory.”

Anthropic previously raised $3.5 billion in March 2025, achieving a $61.5 billion post-money valuation.

Recent Revenue Surge

The latest funding round follows reports indicating Anthropic was poised to secure between $3 billion and $5 billion at a $170 billion valuation.

The company has demonstrated significant growth, with annual recurring revenue increasing from $1 billion to $5 billion throughout 2025.

This surge is attributed to increased API usage and wider enterprise adoption.

The number of large accounts – defined as customers generating over $100,000 in annual revenue – has increased nearly sevenfold in the past year.

Maintaining growth and competing effectively with companies like OpenAI and Cursor necessitates further investment.

CEO Dario Amodei acknowledged the complexities of accepting funds from sovereign wealth funds associated with authoritarian regimes.
