SiFive raises $400m Series G at $3.65bn valuation in final round before IPO

"SiFive raised $400 million in an oversubscribed Series G funding round, achieving a valuation of $3.65 billion. The round was led by Atreides Management and backed by major investors including Nvidia and Apollo Global Management."

"RISC-V is an open-source instruction set architecture developed at the University of California, Berkeley, allowing free implementation and commercialization without the restrictions associated with proprietary architectures like Arm and Intel."

"SiFive's business model is similar to Arm's, focusing on designing CPU intellectual property and licensing it to customers, but operates on an architecture that no single company controls."

"The launch of Arm's AGI CPU in March 2026 marked a shift from being a neutral IP licensor to a company with direct hardware ambitions, creating vertical conflicts that drive technology buyers towards open-source solutions."
