OpenAI and Broadcom have entered a long-term collaboration to co-develop 10 gigawatts of AI accelerators and Ethernet-based systems. This partnership marks OpenAI’s bold step toward building its own chip ecosystem to meet the growing global demand for AI.
OpenAI Expands Its AI Ambitions with Broadcom Partnership
OpenAI has announced a major partnership with Broadcom to design and deploy a new generation of custom AI accelerators and networking systems. The multi-year collaboration will see both companies develop advanced infrastructure to support OpenAI’s expanding AI ecosystem—laying the groundwork for the next leap in artificial intelligence capabilities.
The deal represents 10 gigawatts of OpenAI-designed accelerators, integrated with Broadcom’s Ethernet connectivity and hardware solutions. These AI racks are set for deployment beginning in late 2026, with completion expected by the end of 2029.
A Step Toward Full AI Ecosystem Control
For years, OpenAI believed that smarter algorithms were the key to reaching artificial general intelligence (AGI). However, experience proved that scale and compute power were equally critical. The collaboration with Broadcom is a direct response to that realization—allowing OpenAI to design every layer of its hardware stack, from custom silicon to networking.
“Partnering with Broadcom is a critical step in building the infrastructure needed to unlock AI’s potential,” said Sam Altman, co-founder and CEO of OpenAI. “Developing our own accelerators ensures that what we learn from creating frontier models can be embedded directly into the hardware.”
By controlling the hardware design, OpenAI gains deeper integration between its software and infrastructure—similar to how Apple revolutionized the smartphone industry with its M-series chips. The goal is to deliver faster, more efficient, and cost-effective AI systems that can scale globally.
Broadcom’s Role in the Future of AI Compute
Broadcom brings its extensive expertise in Ethernet, PCIe, and optical connectivity to the collaboration. The company will help OpenAI develop scalable, power-efficient systems capable of handling massive AI workloads.
“This collaboration with OpenAI represents a pivotal moment in the pursuit of general artificial intelligence,” said Hock Tan, President and CEO of Broadcom. “Together, we’re developing next-generation accelerators and networking systems that will define the future of AI infrastructure.”
The systems will leverage Broadcom’s standards-based Ethernet solutions, allowing OpenAI’s data centers to scale seamlessly while maintaining high performance and efficiency.
Building the Physical Backbone of AI
The partnership is part of OpenAI’s broader infrastructure initiative, often referred to as “Stargate” — a massive program designed to deliver the physical foundation of AI computing. OpenAI has already secured major deals with Nvidia and AMD, collectively representing tens of gigawatts of computing power.
Through Broadcom’s custom silicon, OpenAI aims to gain more control over performance, cost, and optimization—enabling faster model training and inference for its widely used tools, including ChatGPT, which now reaches over 800 million weekly active users worldwide.
Empowering Developers and Enterprises
Beyond hardware, OpenAI is also expanding its developer ecosystem. Through initiatives like DevDay, the company introduced new tools such as AgentKit, enterprise APIs, and an App Store integrated directly into ChatGPT. These resources are designed to help developers build, publish, and monetize AI-driven applications more efficiently.
Industry experts describe OpenAI’s strategy as the “Apple playbook for AI”—owning the entire stack from chips to user-facing products. This vertical integration makes OpenAI’s ecosystem more resilient and attractive for both developers and businesses.
A Vision Toward the Future
OpenAI’s growing investments in custom chips, scalable data centers, and developer tools indicate a clear direction: full ecosystem ownership. By aligning with Broadcom, OpenAI is not just improving performance—it’s positioning itself at the heart of the global AI infrastructure.
As Sam Altman noted, the collaboration brings OpenAI closer to realizing its long-term mission: ensuring that artificial intelligence benefits all of humanity.
Conclusion
The OpenAI-Broadcom partnership is more than a technology deal—it’s a strategic move that reshapes the future of AI hardware and software integration. As deployments begin in 2026, the world will see how this collaboration powers the next era of intelligent computing.
