SiFive Raises $400M at $3.65B — NVIDIA and Apollo Back the RISC-V Chip IP Pioneer in Its Final Round Before IPO

An oversubscribed Series G for the company that invented RISC-V: Santa Clara-based SiFive closes $400 million at a $3.65 billion valuation led by Atreides Management with NVIDIA, Apollo Global Management, and T. Rowe Price — positioning the open-standard CPU IP licensing company as the alternative architecture of choice for hyperscalers seeking freedom from ARM and Intel, as agentic AI drives surging demand for customizable, energy-efficient data center processors.

THE PARTIES

 

LEAD INVESTOR

Atreides Management + NVIDIA + Apollo Global Management + More

Atreides Management (Boston): growth equity firm led by Gavin Baker (formerly Fidelity OTC Portfolio manager, one of the most successful tech fund managers of his generation). Led the oversubscribed Series G. New investors: NVIDIA (strategic — also partnering on NVLink Fusion integration and CUDA porting to RISC-V); Apollo Global Management ($600B+ AUM alternative asset giant); D1 Capital Partners; Point72 Turion; T. Rowe Price Investment Management. Existing investors reinvesting: Prosperity7 Ventures (Saudi Aramco venture arm); Capital Group; Sutter Hill Ventures. Gavin Baker: "RISC-V is breaking the paradigm of proprietary ISAs — unleashing the full potential of open standards exactly when the industry needs it most."

COMPANY / RECIPIENT

SiFive, Inc.

Santa Clara, CA-based RISC-V processor IP company. Chairman and CEO Patrick Little. Founded 2015 by Andrew Waterman, Krste Asanovic, and Yunsup Lee — the Berkeley researchers who created the RISC-V instruction set architecture. SiFive licenses customizable RISC-V CPU and AI accelerator IP to semiconductor companies and hyperscalers, who incorporate it into custom chips without per-unit royalties. Portfolio: 10B+ cores shipped to date; IP in 500+ chip designs; major hyperscaler collaborations for data center CPU development. Key milestones: NVIDIA committed to porting CUDA to SiFive/RISC-V; Red Hat Enterprise Linux 10 ported to RISC-V; Ubuntu optimized for SiFive. NVLink Fusion integration announced January 2026 — enabling RISC-V CPUs to connect directly to NVIDIA GPUs.

 

DEAL OVERVIEW

SiFive closed its oversubscribed Series G on April 9, 2026, raising $400 million at a $3.65 billion valuation. CEO Patrick Little described the round as the company's final private funding round before an initial public offering, though no specific IPO timeline was announced. The round was led by Atreides Management with participation from NVIDIA, Apollo Global Management, D1 Capital Partners, Point72 Turion, T. Rowe Price Investment Management, and existing backers. The capital will be deployed across two priorities: (1) accelerated development of high-performance RISC-V CPU and AI IP solutions specifically designed for data center workloads; (2) global engineering team expansion to support hyperscaler customer implementations.

NVIDIA's investment is both financial and strategic: in January 2026, SiFive announced the integration of NVIDIA NVLink Fusion into its data center platform — enabling RISC-V-based CPUs to connect directly to NVIDIA GPUs via a coherent, high-bandwidth, low-latency interconnect. This positions SiFive's CPU IP as a complementary layer in NVIDIA's AI infrastructure ecosystem, allowing hyperscalers to build semi-custom AI compute systems combining open-standard RISC-V CPUs with NVIDIA's proprietary GPU accelerators.

 

"Hyperscale customers have made it very clear that it is time to accelerate the availability of open standard alternatives for the data center. Their consistent ask is for customizable CPU solutions in IP form that will enable them to meaningfully differentiate their data center compute solutions."

— Patrick Little, Chairman & CEO, SiFive

THE RISC-V DATA CENTER OPPORTUNITY

RISC-V is an open-source instruction set architecture (ISA) — the fundamental specification governing how a processor interprets and executes software instructions. Unlike ARM (proprietary, licensed by SoftBank's ARM Holdings at royalty rates that increase with chip value) and x86 (controlled by Intel and AMD), RISC-V is free to implement and extend without per-unit royalties. The hyperscale computing industry — which collectively designs tens of billions of dollars of custom silicon annually at Google (TPU), Amazon (Trainium/Inferentia), Microsoft (Maia), and Meta — has historically relied on ARM for CPU cores. SiFive offers a compelling alternative: fully customizable RISC-V CPU IP that allows hyperscalers to differentiate their chips more deeply than ARM's licensing model permits, without Intel's x86 legacy complexity.
