Anthropic Secures $13 Billion Series F, Valuation Hits $183 Billion in AI Expansion

Anthropic has successfully concluded a Series F fundraising effort, raising $13 billion and securing a post-money valuation of $183 billion. The funding round was led by ICONIQ, Fidelity Management & Research Company, and Lightspeed Venture Partners. This injection of capital underscores the company's ongoing expansion and cements its position as a prominent player in the artificial intelligence sector, particularly as a platform for businesses, developers, and advanced users.

Other notable investors participating in the round include significant institutional players and financial entities such as Altimeter, Baillie Gifford, BlackRock, Blackstone, Coatue, D1 Capital Partners, General Atlantic, General Catalyst, the Government of Singapore Investment Corporation (GIC), and Qatar Investment Authority, among others. These investments reflect a strong vote of confidence in Anthropic's growth trajectory and the robustness of its strategic endeavors.

Since the introduction of Claude in March 2023, Anthropic has experienced a substantial acceleration in business activity. By early 2025, the company's annual run-rate revenue had sharply increased to about $1 billion, and by August of that year, it expanded further to surpass $5 billion. This rapid growth trajectory has positioned Anthropic among the fastest-rising technology enterprises globally.

Key to Anthropic's expansion is the focus on safety, technical competency, and frontier research, which includes groundbreaking work in alignment and interpretability. These elements are foundational to the performance and dependability of Anthropic's models. The company now serves over 300,000 business clients, with a significant increase in larger accounts, denoting customers contributing over $100,000 in run-rate revenue each.

The funds from the latest investment round are earmarked for meeting growing enterprise demand, enhancing safety research, and furthering international market presence. For businesses, Anthropic's API and specialized industry solutions enable seamless integration of powerful AI into critical applications. Developers have notably adopted Claude Code since its launch in May 2025, quickly making it a preferred tool, evident from its impressive $500 million in run-rate revenue within just a few months.

Anthropic continues to concentrate on its mission to develop reliable, interpretable, and steerable AI systems. As it scales operations, the company's dedication to innovative research and customer-focused strategies remains at the forefront of its efforts, utilizing the Series F investment to propel further development and expansion.
