LONDON — Artificial intelligence startup CuspAI has reached a valuation of $2.6 billion after raising a $450 million Series B funding round, marking one of the fastest valuation increases in the emerging field of AI-powered materials discovery.
The funding round was co-led by Bezos Expeditions, the investment firm founded by Amazon founder Jeff Bezos, alongside other strategic investors. The deal represents a major vote of confidence in CuspAI’s mission to use artificial intelligence to accelerate the discovery of new materials for industries ranging from energy and manufacturing to climate technology.
The company’s valuation has surged from approximately $520 million to $2.6 billion in just nine months, highlighting growing investor interest in AI systems designed to solve complex scientific problems rather than only generate text, images, or software code.
CuspAI is developing advanced AI models capable of predicting and designing new materials at a speed that traditional research methods cannot match. The company aims to reduce the time and cost required to discover materials with specific properties, potentially transforming industries where innovation has historically depended on years of laboratory experimentation.
Materials discovery is considered one of the most challenging areas of scientific research. Creating materials with improved strength, energy efficiency, durability, or chemical performance often requires extensive testing and experimentation.
By combining artificial intelligence with scientific data, CuspAI seeks to identify promising material structures before they are physically created, allowing researchers to focus resources on the most valuable candidates.
The company’s technology has attracted attention because of its potential applications in some of the world’s biggest industrial challenges. Possible uses include carbon capture, renewable energy systems, batteries, semiconductors, advanced manufacturing, and pharmaceutical development.
The latest investment reflects a broader shift in the AI industry toward what many investors describe as “AI for science.” Instead of focusing solely on consumer applications, a growing number of startups are building AI systems designed to accelerate breakthroughs in biology, chemistry, physics, and engineering.
Investors believe these companies could create significant long-term value because they target problems that affect entire industries rather than individual workflows.
Bezos Expeditions’ involvement further highlights the strategic importance of AI-driven scientific discovery. The investment firm has historically backed companies working on ambitious technologies with the potential to reshape major markets.
CuspAI’s rapid growth also demonstrates increasing confidence in European deeptech companies. While many of the largest AI investments have historically gone to companies in the United States, Europe has become a growing hub for research-driven startups combining artificial intelligence with scientific innovation.
The company plans to use the new funding to expand its research teams, improve its AI models, build partnerships with industrial organizations, and accelerate the development of commercially viable materials.
As global industries search for cleaner energy solutions, more efficient manufacturing processes, and advanced technologies, AI-powered materials discovery could become a critical tool in solving some of the world’s most difficult engineering challenges.
CuspAI’s rise from a startup valued at $520 million to a $2.6 billion company in less than a year reflects a larger trend: investors are increasingly betting that the next generation of artificial intelligence breakthroughs will come not only from digital platforms but also from machines helping humanity discover entirely new physical technologies.
