The valuation of Anthropic jumped to about $350 billion on Tuesday after Microsoft and Nvidia signed new partnerships with the startup, according to Bloomberg.
Microsoft said it will put up to $5 billion into the company, while Nvidia plans to add up to $10 billion, pushing the startup far beyond the $183 billion level it held in September.
Microsoft made the announcement as it continues to widen its AI bets instead of relying only on OpenAI, where it already holds a stake valued at $135 billion, which represents roughly 27% of the for-profit business.
The partnership with Anthropic gives Microsoft another major model developer in an industry now tied closely to cloud spending, GPU access and compute supply.
Microsoft and Nvidia expand commitments with large compute deals
Anthropic agreed to buy $30 billion worth of Azure compute capacity from Microsoft as part of the deal. The startup also secured the option to draw up to 1 gigawatt of extra compute power from Microsoft’s systems.
On the hardware side, Anthropic committed to buying up to 1 gigawatt of compute from Nvidia’s upcoming Grace Blackwell and Vera Rubin systems, which will run future versions of Claude.
Nvidia CEO Jensen Huang said in a video, “This is a dream come true for us. You know, we’ve admired the work of Anthropic and Dario for a long time, and this is the first time we are going to deeply partner with Anthropic to accelerate Claude.”
Jensen said both companies will work on engineering and design so that Claude’s next models run more efficiently on Nvidia hardware. A blog post said this is the first time the two companies will work together to support Anthropic’s future growth through joint design and performance tuning.
Microsoft noted that it has backed OpenAI since 2019, when the group was still coming out of its early nonprofit research phase. OpenAI, which was founded in 2015, has grown sharply since the release of ChatGPT.
The company finished a recapitalization last month, which allowed Microsoft to update the structure of its partnership with OpenAI.
Anthropic strengthens cloud and training ties while Amazon stays involved
Anthropic was created in 2021 by former OpenAI researchers, including CEO Dario Amodei. The company is known for Claude, a model family widely used for crypto research, trading tools, and high-load automation.
Amazon Web Services became the company’s main cloud provider in 2023 and took on the role of primary training partner in 2024. Anthropic said Amazon will continue in both positions even with Microsoft and Nvidia now committing fresh capital and compute.
Microsoft CEO Satya Nadella said, “As an industry, we really need to move beyond any type of zero-sum narrative or winner-take-all hype. What’s required now is the hard work of building broad, durable capabilities together so that this technology can deliver real, tangible local success for every country, every sector and every customer. The opportunity is simply too big to approach any other way.”
Nvidia will report its third-quarter earnings after the bell today, and you can watch it happen right here on Cryptopolitan.
