Anthropic, one of the world’s fastest-growing artificial intelligence companies, announced on Tuesday that it has raised $13 billion in a funding round valuing the company at $183 billion post-money. The investment was led by Iconiq and reflects continued strong investor appetite for AI startups, even amid broader questions about tech sector spending.
The Series F round also saw co-lead participation from Fidelity Management & Research and Lightspeed Venture Partners, alongside major investors such as the Qatar Investment Authority, Blackstone, and Coatue.
Anthropic’s meteoric rise has been fueled by surging demand for its frontier AI models and platform products. The company revealed in a blog post that its annualized run-rate revenue has soared from about $1 billion at the start of 2025 to more than $5 billion by August, underscoring the rapid adoption of its offerings by enterprises and developers worldwide.
Backed by Amazon.com, Anthropic has positioned itself as a leading competitor in the generative AI space, serving more than 300,000 businesses with its Claude family of models. Much of its recent momentum has been driven by Claude Code, its developer-focused tool, and Claude Pro, which continues to gain popularity with individual users for productivity and specialized tasks.
The company said the new capital will be used to expand enterprise capacity, deepen its investment in safety research, and scale globally. These initiatives are intended to strengthen Anthropic’s ability to deliver trustworthy, mission-critical AI solutions for its growing customer base.
Investor interest in Anthropic signals a broader trend of confidence in AI’s long-term potential to reshape industries. By bringing in a diverse set of institutional backers, the company has further solidified its position as one of the most valuable players in the AI ecosystem.
Anthropic’s latest raise puts it in a small league of private AI firms commanding valuations well north of $100 billion, highlighting both the competitive intensity and the investor conviction driving the next wave of AI innovation.
