CuspAI: Bezos supports $2.6 billion materials-AI startup

      Jeff Bezos seems to have established his focus on AI, which does not involve chatbots but rather the physical realm. According to the Financial Times, CuspAI, a startup from Cambridge that has been utilizing AI to create new materials for two years, is in negotiations to secure around $400 million at a valuation of $2.6 billion. This funding round is being led by Bezos Expeditions, the family office of the Amazon founder, in partnership with Kleiner Perkins. While term sheets have been signed, the deal has yet to be finalized, and CuspAI chose not to provide any comments.

      If successful, this funding would significantly increase the company’s valuation from $520 million in September, marking a fivefold increase in just nine months.

      Described as a “search engine for the material world,” CuspAI was established in 2024 by Chad Edwards, a chemist involved in the formation of quantum-computing company Quantinuum, and Max Welling, a prominent figure in machine learning who was a distinguished scientist at Microsoft Research. Its advisory board features notable AI figures Geoffrey Hinton and Yann LeCun.

      The concept allows users to specify required properties such as strength, conductivity, or heat resistance, and the system can suggest chemical compositions up to ten times quicker than traditional methodologies. What sets it apart is its “synthesis-aware” models, meaning the recommended materials are feasible for production rather than mere simulations. Companies like Meta are already utilizing it for carbon capture, Hyundai for clean energy, and Kemira for removing PFAS “forever chemicals” from water.

      The timing of this move is significant. Just six days prior, Bezos presented Prometheus, a physical-AI lab valued at around $41 billion, aimed at revolutionizing engineering in the same way large language models transformed text – marking his first CEO role since departing Amazon. CuspAI aligns perfectly with this vision, positioning itself at the intersection of generative AI and the tangible world. While Bezos Expeditions has made smaller investments in Anthropic, Perplexity, and Figure AI, he now appears to be most convinced about the potential of materials science within the AI sector.

      Bezos is not alone in this space. XtalPi has a valuation of approximately $2.5 billion, Periodic Labs (established by former OpenAI and DeepMind employees) raised a $200 million seed round at a valuation of $1 billion, and European competitors Altrove and Dunia Innovations are pursuing similar opportunities.

      However, there are legitimate concerns. The funding round remains unclosed, the valuation represents a significant increase for a lab of about 65 employees, and AI-designed materials are still an emerging commercial opportunity rather than a confirmed business. Nevertheless, the two nine-figure investments Bezos has made in physical AI within a week strongly signals where one of the industry's leading figures believes the future value lies, and it is emerging in the UK.
