Summary
Latham & Watkins has advised lead investors Kleiner Perkins and NEA on CuspAI's US$450 million Series B funding round, bringing the frontier AI materials company to a US$2.6 billion valuation. The transaction represents a significant expansion of the investor base beyond traditional venture capital, reflecting intensifying strategic interest in AI infrastructure and materials science.
The round's syndicate composition signals broad institutional confidence in CuspAI's mission to develop breakthrough materials for advanced AI systems. Alongside Kleiner Perkins and NEA, the funding round attracted new strategic investors including Bezos Expeditions, Glade Brook Capital Partners, Lux Capital, and notably corporate venture arms AMD Ventures. The participation of government-backed vehicles—the UK's Sovereign AI Venture Fund and the Netherlands' Invest-NL—underscores the geopolitical significance of AI infrastructure development. Existing investors Temasek, Basis Set Ventures, Giant Ventures, Touring Capital, Prosus, Phoenix Court, and Northzone also participated.
The Latham & Watkins team, led by London corporate partner Shing Lo with associate Vladislav Vasiliev, brings continuity to CuspAI's financing trajectory, having previously represented investors on the company's US$100 million Series A round. The expansion from US$100 million to US$450 million in a single funding round reflects accelerating capital deployment into frontier AI infrastructure—a sector Kleiner Perkins has prioritized as part of its broader US$3.5 billion AI-focused investment initiative launched in early 2026.
CuspAI's focus on materials innovation positions it in a critical but often underappreciated segment of the AI value chain. As compute demands intensify, the availability of specialized materials becomes essential infrastructure. The round's composition—combining traditional venture capital, corporate innovation arms, and sovereign investment vehicles—suggests CuspAI addresses a genuine bottleneck in global AI capability development.
