Anthropic, a US-based AI safety and research company, has secured $13bn in a Series F funding round, raising its valuation to $183bn. The financing aims to bolster its enterprise adoption initiatives, deepen safety research, and support international expansion efforts. Anthropic CFO Krishna Rao said the funding demonstrates investors' confidence in the company's financial performance and growth. The company is backed by major tech players like Alphabet and Amazon and has seen exponential growth in demand across its customer base.

Anthropic, a leading AI safety and research company based in the United States, has secured a significant $13 billion investment in its Series F funding round. This substantial funding round has pushed Anthropic's valuation to an impressive $183 billion. The financing was led by ICONIQ Capital, with co-leads from Fidelity Management & Research and Lightspeed Venture Partners. Additional investors in this round include the Qatar Investment Authority, Blackstone, and Coatue, among others [1].

The funding aims to bolster Anthropic's enterprise adoption initiatives, deepen its safety research, and support international expansion efforts. According to Krishna Rao, Anthropic's CFO, the funding demonstrates investors' extraordinary confidence in the company's financial performance and the strength of its collaboration with key partners to continue fueling its unprecedented growth [1].

This new valuation represents a significant jump from March 2025 when the company was valued at $61.5 billion following a $3.5 billion raise in a Series E round led by Lightspeed Venture Partners. Earlier reports in July 2025 indicated that Anthropic was finalizing a funding round targeting a $170 billion valuation, with expectations to raise up to $5 billion. The company has surpassed these projections with the latest round [1].

Anthropic is backed by major tech players such as Alphabet and Amazon. The company was founded in 2021 by former OpenAI employees and focuses on developing sophisticated AI models, particularly for coding applications. In November 2024, Amazon increased its investment by an additional $4 billion, raising its total stake to $8 billion. Amazon Web Services (AWS) serves as Anthropic’s primary training partner, providing AWS Trainium and Inferentia chips for future model development. Google also expanded its financial backing of Anthropic with over $1 billion invested early in 2025, supplementing a previous $2 billion investment in 2023 [2].

Anthropic’s revenue trajectory has been steep, growing from approximately $1 billion at the start of 2025 to over $5 billion by August. In August 2025, the company launched an upgrade called Opus 4.1 for its Claude large language models, enhancing capabilities related to agentic tasks, real-world coding, and reasoning. Additionally, Anthropic announced that it would offer its Claude model to the US government for $1, aligning it with other approved AI solutions like OpenAI's ChatGPT and Google's Gemini as recognized vendors by the US government's central purchasing arm [2].

The Series F investment will enable Anthropic to meet growing enterprise demand, deepen its safety research, and support international expansion as it continues building reliable, interpretable, and steerable AI systems. This investment underscores the company's rapid growth and the confidence of investors in its mission to develop safe and effective AI solutions.
