Meta Platforms (NASDAQ: META) has acquired chip startup Rivos to enhance its AI capabilities and reduce reliance on external suppliers. This move, announced on September 30, 2025, aims to integrate Rivos's RISC-V-based processors and GPUs, accelerating Meta's custom AI chip development. The acquisition reflects a broader trend of tech giants pursuing vertical integration in AI hardware, potentially impacting companies like Nvidia. Rivos was previously seeking funding at a $2 billion valuation.
Meta is acquiring chip startup Rivos Inc. for around $2 billion to enhance its AI hardware capabilities and reduce reliance on Nvidia GPUs. Rivos, known for its RISC-V–based AI GPU, raised $250 million in April 2024. This acquisition aligns with Meta's strategy to develop in-house AI chips by 2026, aiming to cut AI compute costs. The move is part of a broader trend among tech giants to control AI chip development, challenging Nvidia's market dominance.
U.S.-based semiconductor startup Rivos is aiming to raise between $400 million and $500 million to develop advanced graphics processing units (GPUs) designed to compete directly with NVIDIA in the fast-growing artificial intelligence (AI) chip market.
Santa Clara, California-based Rivos is reportedly developing a chip optimized for artificial intelligence inference.
