Thinking Machine Labs Closing $5B Funding Round at $40B Pre-Money Valuation

Thinking Machine Labs, founded by former OpenAI chief technology officer Mira Murati, is in the final stages of a $5B funding round led by Accel that would establish a $40B pre-money valuation. The current valuation represents a decline from the $50B target sought last year but remains significantly higher than the more than $10B valuation following its $2B seed round. The company has lost roughly 33% of its founding team to competitors including Meta and OpenAI.
