Jeff Bezos has thrown his weight — and his money — behind CuspAI, a startup working to solve one of tech’s quieter but more pressing problems: finding new materials for the next generation of computer chips.
The bet comes at a pointed moment. Chipmakers have spent the past several months dealing with a genuine materials shortage, one that’s been rattling supply chains across the industry. CuspAI’s pitch is that AI can speed up the hunt for substitute materials faster than traditional research ever could.
This isn’t the company’s first big check, either. Back in July, CuspAI closed a $450 million Series B round that valued the company at $2.6 billion. That round pulled in a fairly heavyweight group of backers, including Bezos Expeditions, AMD Ventures, Nvidia, and Meta.
CuspAI got its start in 2024 with a much narrower focus than it has today. Originally, the team was using AI to identify and test materials for things like water purification and carbon capture — useful work, but a world away from semiconductors. Somewhere along the way, the company widened its lens to include AI infrastructure, and that shift now looks like good timing given how tight the chip supply chain has become.

Part of what makes the company interesting is its approach to scarcity itself. Elements like tantalum, gallium, and iridium are in short supply, and CuspAI is using AI to search for alternatives with similar properties—materials that could, in theory, stand in for the real thing without sacrificing performance. The stakes here aren’t small.
The International Energy Agency has already flagged that gallium demand from data centers alone could outpace supply within the next several years.
Add geopolitics to the mix, and the picture gets messier still. Tensions between the US and China over rare earth minerals have only added to the uncertainty around where these materials will come from and at what cost.
CuspAI isn’t tackling this alone, either. Beyond the funding, the company launched something called the AI Materials Foundry — a coalition bringing together more than 45 companies from across the industry, including Nvidia, Samsung, Meta, and Hyundai Motor Group.
The idea seems to be that no single company can solve a supply chain problem this tangled on its own, so it makes more sense to pool resources and research across the board.
Whether AI-discovered materials can actually close the gap fast enough remains to be seen. But with names like Bezos, Nvidia, and AMD all putting money on the table, there’s clearly a belief that this is worth betting on now rather than waiting for the crisis to sort itself out.
