Background
SiFive, a semiconductor design firm backed by Nvidia, has secured $400 million in a new funding round that values the company at $3.65 billion. This shows that investors are becoming more interested in open chip technology for AI systems.
The round was oversubscribed and was led by Atreides Management, founded by former Fidelity investor Gavin Baker. Nvidia joined the funding along with major investors such as Apollo Global Management, D1 Capital Partners, Point72 Turion, T. Rowe Price, and Sutter Hill Ventures, according to reports.
SiFive was founded in 2015 by engineers from the University of California, Berkeley, who developed the RISC-V open-source chip architecture. Unlike traditional processor designs from Intel or Arm, RISC-V gives companies an open and flexible option that they can customize.
SiFive uses a licensing business model. It designs processor blueprints and licenses them to clients. The clients then modify these designs and build chips for their own products. This approach is similar to Arm’s earlier strategy. However, Arm recently shifted direction by manufacturing its own AI chip in partnership with Meta.
SiFive last raised funding in March 2022, when it secured $175 million at a pre-money valuation of $2.33 billion. That earlier round included investors such as Coatue Management, Intel Capital, Qualcomm Ventures, and Aramco Ventures.
With the latest funding and Nvidia’s support, SiFive is now moving beyond its traditional focus on smaller embedded chips and expanding into CPUs designed for AI data centers. The company’s processors are expected to work with Nvidia’s CUDA software platform and NVLink Fusion, a server system that allows different CPUs to connect into Nvidia’s AI infrastructure.
Industry observers see Nvidia’s involvement as a strategic move. While Intel and AMD attempt to challenge Nvidia’s GPU dominance, Nvidia is backing a startup that builds an alternative CPU path using open technology.
The funding round strengthens SiFive’s position as demand rises for flexible and scalable chip designs in the fast-growing AI market.
