AI chip valuations heat up
Investors are valuing AI‑chip startups at premium levels — Nvidia‑backed SiFive has reached a reported $3.65 billion valuation focused on open AI chips. That deal is one signal of elevated investor appetite for semiconductor hardware that supports AI inference at scale. (x.com)
SiFive has raised $400 million at a $3.65 billion valuation, adding fresh evidence that investors are paying up for companies building the chips behind artificial intelligence. (sifive.com) The round was announced April 9 and was led by Atreides Management, with Nvidia, Apollo Global Management, Point72 Turion, T. Rowe Price Investment Management, Prosperity7 Ventures, and Sutter Hill Ventures also participating. SiFive said the financing was oversubscribed. (sifive.com) SiFive does not manufacture finished chips. It licenses processor designs based on RISC-V, an open standard instruction set architecture that lets customers build custom chips without relying on proprietary instruction sets from Arm or x86 suppliers. (riscv.org) (techcrunch.com) The company said the new money will speed up its RISC-V central processing unit and artificial intelligence intellectual property for data centers. Reuters reported the push is aimed at chip technology for the artificial intelligence data center market. (sifive.com) (msn.com) That focus reflects a shift inside artificial intelligence infrastructure. Graphics processing units still handle most model training, but central processing units manage orchestration, memory movement, storage, networking, and many inference tasks that keep large systems running. (forbes.com) (techcrunch.com) RISC-V’s pitch is flexibility. RISC-V International describes it as an open standard, and SiFive is selling that openness to hyperscale cloud companies that want to tune processor designs for their own workloads instead of buying the same general-purpose parts as everyone else. (riscv.org) (sifive.com) The valuation is still small next to Arm, the British chip designer whose September 2023 initial public offering priced at $51 a share and valued the company at more than $54 billion. But it puts SiFive in a richer class of private semiconductor bets than most venture-backed chip startups reached before the artificial intelligence boom. (cnbc.com) Other artificial intelligence chip companies have also climbed quickly. Groq said in September 2025 that it raised $750 million at a $6.9 billion valuation, and Reuters reported in February 2026 that Cerebras Systems raised $1 billion at a $23 billion valuation. (techcrunch.com) (theoutpost.ai) Nvidia’s presence in the SiFive round adds another layer. Reuters reported that Nvidia joined the financing even though SiFive’s RISC-V designs offer an alternative to the Arm and x86 central processors that sit alongside Nvidia’s graphics processing units in many artificial intelligence servers. (msn.com) For now, the financing says more about investor appetite than public-market proof. SiFive has a bigger balance sheet, a clearer data-center pitch, and a valuation that shows private capital still wants exposure to the hardware layer of artificial intelligence. (techcrunch.com)
