Meta has acquired RISC-V chip startup Rivos to help boost its internal semiconductor development efforts, per a report from Bloomberg.

Terms of the deal have not been disclosed, but in August, it was reported that Rivos was looking to raise $500 million at a valuation of $2 billion.

Founded in 2021 and headquartered in Santa Clara, Rivos has been developing an AI inferencing chip based on RISC-V architecture - an open standard instruction set architecture (ISA) provided under open-source licenses that do not require fees.

The company completed its design earlier this year and has handed it off to TSMC for trial production, the August report noted, adding that Rivos had been looking to release its AI chip as early as 2026.

Meta has long been looking to develop its own chips in order to reduce its reliance on Nvidia hardware, with its chips, dubbed the Meta Training and Inference Accelerator (MTIA), first reported to be in development in 2023. Based on 7nm nodes and providing 102 Tops of Integer (8-bit) accuracy computation or 51.2 teraflops of FP16 accuracy computation, the chips run at 800 megahertz and are about 370 millimeters square.

However, despite the existence of the MTIA chips, sources cited by Bloomberg claimed that Meta CEO Mark Zuckerberg is unhappy with the progress of the company’s semiconductor development efforts and has been looking to bring in reinforcements to bolster the team’s work.

In March 2025, South Korean chip startup FuriosaAI turned down an $800 million acquisition offer from Meta.

In a statement to Bloomberg, a Meta spokesperson said: “Our custom silicon work is progressing quickly, and this will further accelerate our efforts.”

The acquisition would represent something of a turnaround for Rivos, with Apple having filed a lawsuit against the chip startup alleging it had hired a number of the tech giant’s former engineers and had then used confidential information to develop rival chips.

Rivos denied the allegations and countersued. But, while fighting the lawsuit, the company reportedly laid off around six percent of its workforce and delayed a planned $400 million Series A fundraising round.

The two companies announced a joint settlement of the cases in February 2024, though terms were not disclosed.
