Thinking Machines, the artificial intelligence laboratory established by former OpenAI CTO Mira Murati, is reportedly in advanced negotiations to secure $1 billion in fresh capital. The funding round, which is expected to be led by existing investor Accel, would place the startup’s valuation at approximately $40 billion.

This potential valuation marks a notable adjustment from the $50 billion target the company was reportedly pursuing late last year. Despite the shift in valuation expectations, the startup continues to demonstrate significant commercial traction, currently maintaining an annual revenue run rate exceeding $100 million. This figure highlights the aggressive revenue multiples currently commanded by top-tier AI firms in the private market.

Since its inception, Thinking Machines has attracted substantial attention and capital, including a historic $2 billion seed round led by Andreessen Horowitz, with participation from industry giants like Nvidia. The company has been actively expanding its product ecosystem, recently launching ‘Inkling,’ an open-weight model designed to generate revenue through compute fees on its proprietary Tinker platform. While the firm has experienced some leadership turnover, including the departure of key co-founders, it remains a central player in the competitive landscape of generative AI development.

Key Takeaways

• Thinking Machines is negotiating a $1 billion funding round that would value the AI startup at $40 billion.
• The company currently reports an annual revenue run rate of over $100 million, driven by its Tinker platform and Inkling model.
• The potential deal follows a massive $2 billion seed round that previously valued the company at $12 billion.

Editor’s Analysis & Impact

The proposed $40 billion valuation for Thinking Machines underscores the persistent investor appetite for foundational AI companies, even as the market begins to scrutinize revenue multiples more closely. While the valuation is lower than previous internal targets, it still represents a massive premium relative to the company’s current $100 million revenue run rate. This suggests that investors are betting heavily on the long-term scalability of the Tinker platform and the technical pedigree of the founding team. However, the company faces significant pressure to prove its long-term viability amid high-profile personnel departures and a crowded AI landscape. The ability to maintain momentum while transitioning from a research-heavy startup to a revenue-generating enterprise will be the primary indicator of whether Thinking Machines can justify its premium valuation in the coming years.
