The move: Broadcom stock spiked as much as 9% on Monday. The chip maker is up 50% in 2025.
Why: Broadcom and OpenAI announced a strategic agreement on Monday for 10 gigawatts of custom AI accelerators. Under the agreement, OpenAI will design the systems, which Broadcom will help develop and deploy.
According to a statement released on Monday, Broadcom is expected to start deploying these accelerator racks and network systems by the second half of 2026 and finish in 2029. They will be spread across OpenAI's own facilities and partner data centers.
"Developing our own accelerators adds to the broader ecosystem of partners all building the capacity required to push the frontier of AI to provide benefits to all humanity," OpenAI CEO Sam Altman said in Monday's statement.
The chart:
What it means: The agreement with Broadcom is the latest in a long string of deals OpenAI has inked to build out AI infrastructure and computing power. The financial terms of the latest deal weren't revealed by the companies, but OpenAI has done $1 trillion of deals for AI compute in 2025 alone.
"Our partnership with OpenAI continues to set new industry benchmarks for the design and deployment of open, scalable and power-efficient AI clusters," said Charlie Kawwas, Ph.D., President of the Semiconductor Solutions Group for Broadcom.
The ChatGPT maker has regularly sent stocks surging on news of big collaborations with hardware makers and other partners. AMD soared almost 40% in a day at the end of September after OpeanAI announced a major chip deal that also gives it the option to take a 10% stake in the company.
