CuspAI raises $450 million and launches AI Materials Foundry

British AI materials-discovery startup CuspAI announced a $450 million Series B funding round at a $2.6 billion valuation and launched the AI Materials Foundry.

The foundry brings together more than 45 companies and research organizations, including Nvidia and Meta. Its focus is AI-driven materials discovery, an area with potential applications across semiconductors, energy and advanced manufacturing.

The scale of the financing is notable for a science-focused AI company. Combined with the new consortium, it could give CuspAI access to more capital and industry participation as it works on discovering materials for strategically important sectors.

Confirmed details include the size and Series B status of the round, the $2.6 billion valuation, the launch of the AI Materials Foundry and the coalition’s size. Nvidia and Meta are confirmed as participants in the coalition.

What remains uncertain is how quickly the initiative will produce commercially useful materials or measurable improvements for the industries it targets. The supplied package does not provide development timelines, performance benchmarks or specific commercialization commitments from coalition members.
