Venture firm Accel is reportedly in negotiations to lead a $1 billion funding round for AI company Thinking Machines, according to TechCrunch, which would value the startup at approximately $40 billion.

What Happened

TechCrunch reported that Accel is working to secure the role as lead investor in a substantial new funding round for Thinking Machines. The firm is reportedly pushing to commit at least $250 million to the deal, with a pre-money valuation that could reach $40 billion. The talks remain ongoing and terms are subject to change.

Why It Matters

A successful $1 billion raise would position Thinking Machines among the most valuable private AI companies globally. For developers and enterprises evaluating AI infrastructure choices, continued heavy investment in frontier AI labs signals sustained competition for talent and compute resources. If finalized at these figures, the round would also underscore investor appetite for large-scale AI bets despite market concerns about returns timelines.

The Bottom Line

Accel's reported interest in leading a $40 billion valuation round for Thinking Machines reflects continued venture confidence in frontier AI companies. The talks are ongoing and terms could shift before any deal closes.
