Nvidia plans $2.5 billion investment in Thinking Machines Lab startup

Nvidia is in talks to put about $2.5 billion into Thinking Machines Lab, an AI company started by former OpenAI executive Mira Murati. The startup is raising between $5 billion and $6 billion in total, which would give it a value of at least $40 billion. Investment firm Accel is leading the fundraising effort. Nvidia's share would be roughly half of the whole round. The two companies already have a partnership from March, when Thinking Machines agreed to use at least one gigawatt of Nvidia's next-generation Vera Rubin computing systems, starting in early 2026. Nvidia has also bought stakes in other AI companies, including OpenAI and Anthropic. This deal would give Nvidia both a long-term customer and a direct share in a major AI business.
