Anthropic IPO: Amazon, Google could make staggering over USD 400 billion from Claude maker's successful listing. Here's how

Anthropic IPO has raised eyeballs as the Claude maker is eyeing to rake up $64 billion in its upcoming initial public offering. According to Anthropic IPO filing, successful listing could value the AI company at up to $1.4 trillion. Anthropic IPO filing shows that two of its largest backers are Amazon and Google’s parent company Alphabet.

Amazon and Google's stakes in Anthropic could be worth a combined $411 billion if the AI company ​prices its initial public offering at the top ‌of its proposed range, according to Reuters calculations based on a filing. Seven tech companies including Google, Nvidia, AMD and Microsoft have also agreed to buy $26 billion of non-voting shares at the IPO price in a separate private placement, the filing showed.

Other participants include Founders Fund, the venture firm started by Peter Thiel, along with Microsoft and Nvidia. In May, Anthropic raised $65 billion at a $965 billion valuation, which put it ahead of OpenAI for the first time.


Former Google chief executive Eric Schmidt is among the earliest outside investors. He put tens of millions of dollars into Anthropic's first funding round in 2021.

Amazon

Amazon has invested at least $13 billion in Anthropic and in April agreed to invest up to an additional $20 billion. Anthropic also committed to spend more than $100 billion on the e-commerce giant's cloud services over 10 years.

Google-Parent Alphabet

Google has committed up to $40 billion to Anthropic, including an initial $10 billion investment announced in April. The partnership provides Anthropic with cloud infrastructure and access to Google's AI chips, which are used to train and run Claude models.

Microsoft

Microsoft agreed to purchase $1 billion of Anthropic's non-voting shares in the company's $26 billion concurrent private placement at the IPO price. The software giant is also a major backer of OpenAI, Anthropic's chief rival.

Nvidia

Nvidia agreed to purchase $10 billion of Anthropic's non-voting shares alongside the company's stock market listing. The chipmaker is the dominant supplier of AI accelerators used to train and run large language models.

AMD

AMD agreed to purchase $2.5 billion of Anthropic's non-voting shares alongside the company's stock market listing. Under a November 2026 agreement, the investment reduced AMD's equity commitment under a hardware supply agreement to $2.5 billion.
