Rivos Acquisition
Rivos was acquired by Meta for $2B on 30 September 2025.
Before the acquisition Rivos had raised $250M across 1 funding round.
Rivos Inc., a Santa Clara-based startup founded in May 2021, develops high-performance, power-efficient server solutions and custom AI accelerators using open-source RISC-V architecture, including a taped-out 3.1 GHz processor with CUDA-compatible software stack and contributions to Meta's MTIA 1i and 2i compute engines. The company raised $250 million in Series A funding in April 2024, additional $120 million, and was preparing a $500 million Series B in early 2025 at over $2 billion valuation before Meta's acquisition. Co-founded by Puneet Kumar, Mark Hayter, and Belli Kuttanna, Rivos pivoted from CPU designs to AI acceleration post-2023 hiring of Apple engineers, amid a 2023 lawsuit settlement with Apple. Meta Platforms Inc. acquired Rivos in October 2025 via a definitive agreement, advised by Latham & Watkins, with terms undisclosed but estimated north of $850 million based on prior funding and valuation. The deal bolsters Meta's semiconductor development to control its AI infrastructure, reducing NVIDIA GPU dependence, following a failed $800 million bid for Ferocia AI earlier in 2025. Rivos' full-stack chip design team and RISC-V expertise join Meta's efforts in silicon sovereignty, aligning with peers like Google, Amazon, and Microsoft in the AI chip race. The acquisition validates Rivos' disruptive RISC-V vision for next-gen data centers, enhancing ecosystem flexibility and performance without app rewrites, amid hyperscaler scramble for AI compute alternatives to NVIDIA's dominance.

The company leverages open-source RISC-V to avoid licensing fees and plans manufacturing on TSMC's 3nm node. On April 16, 2024, Rivos closed an oversubscribed $250 million Series A-3 funding round led by Matrix Capital Management, with Romit Shah joining the board. New investors included Cambium Capital Partners, Intel Capital, MediaTek, Hotung Venture Group, Capital TEN, CIDC Consultants (via CDIB Capital), Compal Electronics, Delta Electronics Capital, and Singularity Capital Management; returning investors were Walden Catalyst, Dell Technologies Capital, Koch Disruptive Technologies, VentureTech Alliance, Nepenthe Capital, and Factory HQ Advisors. The round issued 128,378,406 Series A-3 preferred shares for gross proceeds of approximately $250 million. Proceeds will finalize first processor design, expand manufacturing, software engineering, technical support, and go-to-market initiatives while hiring engineering talent. This follows a February 2024 settlement of an Apple lawsuit alleging employee poaching and trade secret theft, which had previously caused layoffs and delayed a planned $400 million Series A. |
