CuspAI Hits $2.6 Billion Valuation After Jeff Bezos, Nvidia, and Meta Back AI Materials Startup

Cambridge-based AI startup CuspAI secured $450 million in a Series B funding round on July 20, 2026. The funding pushed its valuation to $2.6 billion, backed by Jeff Bezos, Nvidia, and Meta. CuspAI uses artificial intelligence to discover new materials for chipmaking, clean energy, and manufacturing. The round marks a fivefold jump from its $520 million valuation last September.

CuspAI Funding Round: $450 Million Series B Details

Kleiner Perkins and New Enterprise Associates co-led the Series B round for CuspAI. Bezos Expeditions, the private investment firm of Amazon (NASDAQ: AMZN) founder Jeff Bezos, joined as a significant backer. Total funding for the two-year-old startup now exceeds $580 million.

Other participants brought fresh capital and strategic weight to the round.

• AMD Ventures, the venture arm of chipmaker AMD
• Britain’s Sovereign AI Venture Fund
• Glade Brook Capital Partners and Lux Capital

CuspAI’s earlier rounds included a $30 million seed in June 2024 and a $100 million Series A in September 2025. That trajectory shows investors are betting heavily on AI-driven materials science.

AI Materials Foundry: Nvidia, Meta and Industry Partners

CuspAI also unveiled the AI Materials Foundry, a coalition built to speed up materials discovery. The group brings together more than 45 technology, industrial, and research organizations worldwide.

Nvidia (NASDAQ: NVDA) and Meta Platforms (NASDAQ: META), through its Fundamental AI Research Team, are founding partners. Samsung and Hyundai Motor Group have also joined the coalition. The Foundry pools computing power and lab data across members. This setup lets teams test candidate materials faster than any single company could manage alone.

CuspAI CEO Chad Edwards said 80% of the company’s research will target chip materials this year. The goal is cutting reliance on scarce metals like ruthenium and iridium.

CuspAI’s Growth Trajectory and Technology

CuspAI runs an AI platform called MIRA to simulate how candidate materials perform before lab testing begins. This approach narrows a vast pool of possibilities into testable options quickly.

The startup plans to expand foundry labs across three key locations.

• Cambridge, United Kingdom, its founding headquarters
• Singapore, supporting Asia-Pacific research operations
• San Francisco Bay Area, its new California presence

CuspAI recently hired John Giannandrea, a former senior executive at both Google and Apple, to help build out that California operation. The hire signals CuspAI’s ambition to compete directly with established AI labs on talent and infrastructure.

Bezos has made a broader bet on physical-world AI applications this year. His startup Prometheus raised $12 billion in June 2026, reaching a $41 billion valuation. That scale puts CuspAI’s $2.6 billion valuation into perspective within Bezos’ wider AI portfolio.

Analysts’ View

Industry watchers see CuspAI’s funding as part of a bigger shift in AI investment. Much of the sector’s attention has focused on models that generate text and images. Materials discovery represents a newer frontier, tackling physical bottlenecks that slow down chip production.

Kleiner Perkins partner Josh Coyne framed the opportunity around unresolved scientific gaps holding back cheaper carbon capture and cleaner semiconductor production. The involvement of Nvidia, Meta, AMD, and Samsung together suggests the materials challenge cuts across competitive lines. For now, CuspAI’s rapid rise underscores growing investor appetite for AI applied to physical industries, not just software.
