Simplify's Take
What believers are saying
- Meta's 2025 acquisition validates Rivos's silicon talent and accelerates product adoption.
- Rivos raised more than $250 million in April 2024, funding aggressive chip development.
- Meta sought Rivos to reduce Nvidia dependence and internalize AI compute costs.
What critics are saying
- The Information reported June 2026 layoffs cut more than 25% of ex-Rivos staff.
- Meta paused a large-model training chip project after integration problems in 2026.
- If Meta fully absorbs Rivos, the standalone startup disappears and hiring collapses.
What makes Rivos unique
- Rivos built RISC-V CPUs and GPGPU chips for AI inference and data centers.
- Meta signed a definitive acquisition agreement on October 3, 2025.
- Canonical partnered with Rivos in April 2025 to harden Ubuntu for RISC-V.

↑ 11%Intel providing chip technology to startup in rare deal. Friday, 31 Jul 2026 SAN FRANCISCO: Intel is providing access to some of its processor technology to a new startup, according to a source and documents reviewed by Reuters, in a rare move for the US chipmaker. Intel chief executive officer (CEO) Lip-Bu Tan and the startup's boss are longtime co-investors. The startup, RosaicLabs Inc, filed its first Delaware incorporation documents in May, according to a certificate of incorporation from the state. Reuters could not locate a web page or LinkedIn profile for the company, as is common with early-stage chip startups operating in secrecy. Rosaic's CEO is Amarjit Gill, according to an amended filing in July, a seasoned venture capital investor and chip industry executive who helped Tan build the founding team at another chip company called Rivos, which Meta acquired last year, outbidding Intel. Tan was chairman of Rivos at the time. Tan and Gill both made seed-stage investments in a third chip startup called Nuvia, which was sold to Qualcomm. Intel declined to comment. Rosaic's founding team includes veterans from Rivos, according to a source briefed on the matter and the documents. Amit Parikh, the former finance chief at Rivos, signed the incorporation document. Furthermore, Intel is providing Rosaic access to its Atom technology, the building blocks of central processors, which run on the company's x86 architecture, the source said. Providing access to Rosaic is a rare move by Intel, which has historically not widely licensed pieces of its x86 architecture or provided Atom tech. Intel aims to ship register-transfer level code for the Atom processor tech to the startup, which designers use to describe chip functions, the source said. - Reuters
Terms of the deal have not been disclosed
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.
