OpenAI and Broadcom Team Up for AI Accelerator Revolution
OpenAI and Broadcom announced a multi‑year strategic collaboration to co-develop and deploy 10 gigawatts of custom AI accelerators and associated network systems. OpenAI will design the accelerators and systems, and Broadcom will provide Ethernet, PCIe and optical connectivity solutions and deploy racks of the accelerators. The deployment is targeted to begin in the second half of 2026 and to complete by the end of 2029. The companies have signed a term sheet for racks incorporating OpenAI’s accelerators and Broadcom networking solutions, with deployments across OpenAI facilities and partner data centers. The announcement emphasizes custom accelerators and Ethernet-based scale-up and scale-out networking as key elements for next-generation, power-efficient AI clusters. OpenAI stated it has over 800 million weekly active users.
Major infrastructure collaboration between a leading AI platform (OpenAI) and a major semiconductor/networking vendor (Broadcom) to deploy 10 GW of custom accelerators will materially affect AI compute capacity, datacenter networking choices (Ethernet), and future model development.

Broadcom Expands AI Chip Deals with Google, Anthropic
Broadcom said it will produce future versions of AI chips for Google and signed an expanded agreement with Anthropic that gives the startup access to roughly 3.5 gigawatts of compute capacity using Google’s tensor processing units (TPUs). The deals were disclosed publicly and helped Broadcom shares jump more than 6% intraday. Analysts at Mizuho and Citi maintained buy ratings, with Mizuho saying the tighter TPU partnership strengthens Broadcom’s position. CEO Hock Tan has projected AI chip revenue in 2027 “significantly in excess of $100 billion.” Earlier estimates from filings and analyst commentary suggested Broadcom could capture tens of billions in AI-related revenue from customers like Anthropic as model builders continue to source diverse accelerator capacity.
OpenAI Teams Up with Cerebras for AI Innovation
OpenAI announced a partnership with Cerebras to add 750 MW of ultra low-latency AI compute to OpenAI’s platform. Cerebras’ systems use a single large chip combining compute, memory and bandwidth to accelerate inference. OpenAI said the capacity will be integrated into its inference stack in phases across workloads and will come online in multiple tranches through 2028. OpenAI’s Sachin Katti and Cerebras co-founder and CEO Andrew Feldman are quoted describing the deal’s aim to enable faster, more natural real-time AI interactions and scale real-time inference to more users. The announcement was published by OpenAI on January 14, 2026.
Meta, Broadcom Agree on 1GW Custom AI Chip Deal
Meta and Broadcom announced a multi-year partnership extending through 2029 for the design of Meta's custom in-house AI accelerators. Meta committed to an initial deployment of 1 gigawatt of its Training and Inference Accelerators (MTIA) and plans to scale to multiple gigawatts in 2027 and beyond. Broadcom said MTIA chips will be the first AI silicon using a 2-nanometer process. Broadcom CEO Hock Tan informed Meta he will not stand for reelection to Meta’s board; Tracey Travis will also leave the board. The agreement follows Broadcom’s recent deals with Google and Anthropic and comes as Meta pursues large-scale AI investments while expanding its data center footprint.
