Meta to acquire Rivos to accelerate in-house AI silicon

Meta plans to buy RISC-V startup Rivos to deepen its custom accelerator stack — a step toward reducing reliance on merchant silicon.

What’s new

Meta is set to acquire Rivos, a Santa Clara startup focused on RISC-V and full-stack AI systems. Terms weren’t disclosed. The move aligns with Meta’s MTIA roadmap and the industry trend toward vertically integrated AI silicon.

Why it matters

• Cost + control: Owning more of the stack helps rein in inference costs and lets Meta shape hardware to software (and vice-versa).
• Supplier balance: Doesn’t end Nvidia dependence overnight, but chips away at it long term.

The big picture

Everyone at scale is moving toward custom accelerators. The question isn’t whether — it’s how fast they can get useful work per watt. For background, see
