RISC-V chip designer SiFive closed a $400 million Series G round on April 9, led by Atreides Management with participation from Nvidia, Apollo Global Management, Point72 Turion, and T. Rowe Price, valuing the company at $3.65 billion — its first fundraise since a $175 million round at $2.33 billion in 2022. Proceeds will fund high-performance RISC-V CPU and AI accelerator IP for data centers, with SiFive specifically targeting agentic AI workloads and integrating with Nvidia's NVLink Fusion technology. CEO Patrick Little told Reuters this is the final private round before an IPO, though no exchange or pricing timeline has been set.
