Accel reportedly in talks to lead $1 billion Thinking Machines round at $40 billion valuation

9/4/2026

A reported $1 billion funding round for Thinking Machines, the artificial intelligence startup, would set a $40 billion headline valuation, with Accel said to be in discussions to lead the raise.

The company's annual revenue run rate has cleared $100 million, the one hard operational figure attached to the reported terms.

The distance between a $100 million-plus run rate and a $40 billion headline is the number this deal will have to carry.

Neither Accel's participation nor the round's final size has been formally confirmed, so the story sits in the talks stage.
