Sources: Mira Murati's Thinking Machines Lab raised $2B led by a16z at a $10B valuation; Murati will hold board voting rights that outweigh all other directors
This former OpenAI CTO has doubled that and retains full voting rights over the board members. @cuibonobaby : “carrying on an undertaking of great advantage but nobody to know what it is”. 😂🤣 Sean O'Kane / @seanokane : “Because of its highly clandestine nature, a number of funds that Murati pitched to passed on the deal, said multiple investors who were approached. One of these people added Murati's pitch offered no information about a product or financial plans.” — 🧐🧐🧐🧐🧐🧐🧐🧐🧐 … Ed Zitron / @edzitron.com : Every single investor involved in this should be savaged by their LPs. In a sane venture community involvement here would be a sign of idiocy. Why even invest? Murati doesn't even sound smart! [embedded post] Corey Quinn / @quinnypig.com : “Absolutely, here's $2B. I love investing in companies where the founder has total control and the rest of the board is just IKEA with titles.” —a16z, apparently.

Context & Ripple Effects
Thinking Machines Lab emerged with Murati as CEO after recruiting researchers and engineers from rivals and pursuing a reported $1B raise at roughly a $9B valuation. This reported $2B round therefore marks a rapid step up in the lab’s financing capacity and founder control.
Later coverage characterized the financing as a $2B seed round involving Nvidia, Accel, ServiceNow, Cisco, AMD, and Jane Street and reported further fundraising discussions at substantially higher valuations, making this round an early marker of investor appetite for the lab.
First-order effects
- Thinking Machines Lab gains $2B in reported financing led by a16z, giving a newly formed AI lab resources to build and recruit without an immediately disclosed product or financial plan.
- Murati’s super-voting board position concentrates formal control with the founder even as outside investors take large economic stakes.
Second-order effects
- The structure makes governance terms—not just valuation—a competitive issue for investors seeking exposure to high-profile frontier AI teams; investors willing to accept founder control may gain access while others pass.
- The round strengthens the lab’s ability to compete for the researchers it had already been recruiting from rival AI organizations, increasing pressure on other labs to defend technical talent.
Third-order effects
- If similar rounds persist, frontier-model development may become more concentrated in a small set of founder-led labs that can raise very large pre-product financings on team reputation and perceived technical potential.
- The later reports of a much higher prospective valuation suggest that private-market pricing can reset quickly ahead of disclosed commercial results, increasing the importance of governance and execution signals in separating durable labs from fundraising momentum.
The trend: This is a data point in frontier AI’s shift toward capital-intensive, founder-controlled labs financed on elite talent and anticipated model capability before product-market evidence is public.
