Summary
Anthropic, the artificial intelligence startup behind Claude, has attracted substantial investor interest as demand for AI models and infrastructure accelerates, according to a report by The Economic Times drawing on agency inputs and Reuters. Its valuation has climbed through successive funding rounds, and its planned initial public offering is expected to be a closely watched test of public-market appetite for AI leaders.
Strategic technology partners anchor the capital base. Amazon has invested at least $13 billion and agreed in April to invest up to an additional $20 billion, while Anthropic has committed to spending more than $100 billion on Amazon's cloud services over 10 years. Alphabet's Google has committed up to $40 billion, including an initial $10 billion investment announced in April. The Google partnership provides cloud infrastructure and access to its AI chips, which are used to train and run Claude models.
Venture capital firms have supported Anthropic across multiple rounds. Spark Capital led the $450 million Series C in May 2023 and secured board representation through general partner Yasmin Razavi. Menlo Ventures made its first investment in 2023, led the Series D in 2024 when Anthropic was valued at $18.4 billion, and participated in the $3.5 billion Series E at a $61.5 billion valuation. Lightspeed Venture Partners led the Series E in March 2025 and co-led the $13 billion Series F in September 2025, which valued the company at $183 billion, according to Reuters. Fidelity Management & Research participated in Series E and co-led Series F, while Salesforce Ventures participated in the Series C and Series E rounds.
Later-stage capital has come from global investment firms and institutional investors. ICONIQ Capital co-led the $30 billion Series G after leading Series F. Singapore's sovereign wealth fund GIC led the Series G, which valued Anthropic at $380 billion. Coatue Management led the Series G and co-led the $65 billion Series H. Sequoia Capital was a significant Series G investor and became one of the lead investors in the Series H, which valued Anthropic at $965 billion. D1 Capital Partners invested across Series E through Series H, and Altimeter Capital invested in Series F and later became a lead investor in Series H.
Individual investors also participate. Jaan Tallinn, co-founder of Skype, led the company's first institutional financing, a $124 million Series A in 2021. Former Google chief executive Eric Schmidt has personally invested in Anthropic.
The article frames the prospective IPO as a test of whether investors beyond Silicon Valley share the conviction of private backers. A listing would give public investors exposure to the AI sector and a clearer read on how markets value leading AI developers, and the reception would inform assessments of growth prospects, computing costs, competition and expected commercial returns from generative AI.
