Thinking Machines, Billionaire Dreams: Murati’s AI Rocket Eyes $50B Orbit

Thinking Machines races toward elite status with bold valuation target  
Founded by former OpenAI CTO Mira Murati, Thinking Machines Lab is in early discussions to raise a new round of funding that could value the company at approximately $50 billion. The startup was last valued at $12 billion in July 2025 after securing $2 billion in capital from backers including Nvidia, AMD, and Jane Street.

The company’s first product, Tinker, helps fine-tune large language models and has gained traction among enterprise clients. Despite co-founder Andrew Tulloch’s recent departure to Meta, Murati’s leadership continues to attract top-tier investor interest. If the deal closes, Thinking Machines would join the ranks of global AI giants like Anthropic and xAI, less than a year into its journey.

Major takeaways  

• Thinking Machines targets $50 billion valuation in upcoming funding round  
• Startup previously raised $2 billion at $12 billion valuation in July 2025  
• Founded by ex-OpenAI CTO Mira Murati; co-founder Andrew Tulloch recently exited  
• First product Tinker focuses on enterprise-grade LLM fine-tuning  
• Potential to become one of the world’s most valuable private AI firms
