SiFive Raises $400 Million to Accelerate High-Performance RISC-V Data Center Solutions, Valuing the Company at $3.65 Billion

SiFive, the gold standard for RISC-V processor IP, led by Patrick Little, Krste Asanovic, Yunsup Lee, Andrew Waterman, and the team, has raised $400 million in an oversubscribed Series G financing led by Atreides Management with other A-list investors, including Apollo Global Management, NVIDIA, Point72 Turion, and T. Rowe Price Investment Management, Inc., alongside repeat investors Prosperity7 Ventures, and Sutter Hill Ventures.

For Patrick Little, rising demand from hyperscalers is accelerating the need for open, customizable CPU architectures in data centers. SiFive positions RISC-V as the key solution, enabling differentiated compute systems and supporting the industry’s shift toward agentic AI, while unlocking a significant share of this emerging opportunity.

SiFive is Doubling Down on the Data Center

SiFive is accelerating its push into data centers, with new funding supporting next-generation solutions and expanded global engineering teams for agentic AI workloads.

Investment focus:

• Advanced R&D: Expansion of high-performance RISC-V CPU, accelerator, and system IP.

• Software ecosystem: Growth of data center software support, including CUDA, Red Hat Enterprise Linux, and Ubuntu.

• Customer enablement: Deeper collaboration with industry leaders, including integration with NVLink Fusion.

The Rise of the Agentic CPU

CPUs are becoming central to agentic AI systems, handling complex coordination tasks that GPUs and accelerators cannot efficiently manage. As models grow more sophisticated, efficient CPU performance is essential to expanding compute within existing power limits.

SiFive addresses this shift with RISC-V CPUs, offering lower power consumption and integrating scalar, vector, and matrix compute into a unified, standards-based architecture, enabling faster scaling and accelerating hardware development alongside AI innovation.

For Gavin Baker, proprietary ISAs have long limited innovation in chip design. SiFive is changing that with RISC-V, offering the performance, efficiency, and flexibility demanded by hyperscalers as agentic AI reshapes data center computing, positioning the company strongly for long-term leadership in this shift.

For Dan Newman, the CPU is regaining importance in data centers as AI workloads evolve. SiFive is well-positioned to benefit from this shift, with RISC-V emerging as a strong alternative to legacy architectures, offering flexibility, efficiency, and the backing of a growing global ecosystem, reinforced by the $400 million investment.

Architecting the Future of Open Compute

RISC-V was designed as an open standard, continuously improved through global collaboration. This approach fosters innovation, ensuring greater choice and flexibility for customers while delivering broader benefits to end users.

For Dave Altavilla, the rapid growth of AI workloads is exposing the limits of legacy CPU architectures not designed for modern performance-per-watt demands. SiFive’s latest funding signals a shift toward RISC-V, with increasing collaboration across hyperscalers and ecosystem partners. If sustained, this momentum positions the company to capture a share of a potential $100B+ market in next-generation AI and agentic data center infrastructure.
