Nvidia in talks to invest in Anthropic’s mega IPO: Sources

Anchor investors are typically institutional investors that commit to buy a set portion of an IPO before it is marketed more broadly, providing an early vote of confidence in the shares. 

It is increasingly common for mega IPOs to line up early institutional commitments, given the large amounts they seek to raise. 

Chip designer Arm’s anchor investors included Nvidia and Amazon, while Saudi Arabia’s PIF was among SpaceX’s anchor investors.

The deepened relationship highlights the complex ties between AI model developers and the companies supplying the enormous amounts of computing power they require. 

Anthropic relies heavily on Nvidia graphics processing units (GPUs), while also seeking to diversify its chip suppliers as demand for Claude has strained its available computing capacity.

In November 2025, Nvidia said it would invest up to US$10 billion in the AI startup as part of a broader partnership under which Anthropic committed to buy US$30 billion of Microsoft Azure computing capacity powered by Nvidia chips. 

Anthropic already counts the biggest tech companies in the world as backers. 

These include Amazon and Google, who are also its major compute suppliers. In April, Anthropic said it would commit more than US$100 billion over a decade to Amazon’s AWS, while using more than 1 million of Amazon’s Trainium2 chips. 

It has also agreed with Google and Broadcom to add multiple gigawatts of TPU capacity.
