OpenAI Set to Build Custom AI Chips with Broadcom

OpenAI, the company behind ChatGPT, is preparing to launch its first-ever custom AI chip in partnership with U.S. semiconductor giant Broadcom. The chip, expected to roll out in 2025, marks a major step toward reducing OpenAI’s reliance on Nvidia GPUs, which currently dominate the AI hardware market.

Why OpenAI Is Making Its Own AI Chip

The rise of advanced generative AI models like GPT-5 requires massive computing power. OpenAI has been one of Nvidia’s largest customers, but the demand for GPUs has led to high costs and supply challenges. To address this, OpenAI began exploring options as early as 2023, working not only with Broadcom but also Taiwan Semiconductor Manufacturing Company (TSMC) and even incorporating AMD chips to diversify supply.

Developing a custom AI processor gives OpenAI several advantages:

• More control over performance tailored to AI workloads.
• Reduced costs by cutting dependency on external suppliers.
• Scalability to support the rapid growth of ChatGPT and other AI tools.

Broadcom’s Big Role in the Deal

Broadcom’s CEO, Hock Tan, recently revealed that the company secured more than $10 billion in AI chip orders from a new client. While Broadcom has not named the customer, insiders confirmed it is OpenAI. The news boosted Broadcom’s stock by over 15%, raising its market cap to $1.7 trillion.

Shipments of these new custom AI chips are expected to begin in 2025, with full-scale production likely stretching into 2026. Tan also suggested that Broadcom’s custom AI chip business could grow faster than Nvidia’s over the next few years.

A Growing Trend Among Tech Giants

OpenAI is not alone in this strategy. Other tech leaders like Google, Amazon, and Meta have already developed in-house chips to handle AI workloads. The goal is the same: secure reliable computing power and reduce dependency on Nvidia.

Industry analysts believe this move will shake up the AI infrastructure market, which has so far been dominated by Nvidia GPUs. While Nvidia still maintains a strong hold, its growth has slowed compared to the early boom of AI investment.

What This Means for OpenAI

For now, OpenAI plans to use its custom chips internally to power ChatGPT and train future models. Unlike Nvidia’s GPUs, these chips won’t be sold to other companies—at least not yet.

CEO Sam Altman has stressed the urgent need to expand compute resources, recently saying OpenAI would double its compute fleet in just five months to meet rising demand. With custom hardware, the company is positioning itself for long-term scalability.

Final Thoughts

This partnership between OpenAI and Broadcom signals a new era in the AI hardware race. If successful, it could help OpenAI secure the compute it needs to push forward breakthroughs in generative AI while creating real competition for Nvidia.
