Thinking Machines Lab is reportedly closing a $5B round at a $40B pre-money valuation
These are unnamed-source reports of a round that has not been announced. Thinking Machines declined to comment and Accel did not respond, according to the report. This edition read Business Insider's article as republished by another site. The valuation is private financing, not a public market value, and the report gives no revenue figure to compare it with.
What was claimed?
Business Insider reported on November 6, 2026, citing multiple people familiar with the matter, that Thinking Machines Lab, the AI company founded by former OpenAI chief technology officer Mira Murati, is raising $5 billion at a $40 billion pre-money valuation, with Accel leading, and could close as soon as this week. The report says the company was previously valued at more than $10 billion when it raised a $2 billion seed round last year, and that talks last year at a $50 billion valuation were abandoned.
What does the evidence support?
Reported claim, not independently established
The reported round comes days after the sharp fall in AI shares and reports of investors pressing for a lower Anthropic IPO valuation, and it suggests private investors are still making very large bets on newer AI labs. Business Insider notes the company has also lost several founding members to rivals.
