Less than a year after launch, Mira Murati’s AI venture Thinking Machines is reportedly in talks to raise fresh funding at a staggering $50 billion valuation. The move could catapult the startup into the ranks of the world’s most valuable private tech firms, signaling investor confidence in next-gen AI infrastructure.
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.
