Positron AI raises $875 million Series C at $5 billion valuation
Positron AI, based in Reno, Nevada, has raised $875 million in a two-tranche Series C funding round. The first tranche of $375 million was led by NEA and several other firms, including SemiAnalysis Capital managed by Dylan Patel. A follow-on $500 million tranche is anchored by NEA and Jim Clark, co-founder of Netscape. The company's valuation has surged from $1 billion in February 2026 to $5 billion following this round. Positron specializes in AI inference chips with a focus on memory capacity rather than raw compute power. Its next-generation chip, Asimov, is set for production by mid-2027 and will be used in the Titan system designed for large-scale models. The funding will support development of Asimov, construction of an engineering data center, and scaling up manufacturing to meet growing demand.
