12:24 PM EDT, 10/13/2025 (MT Newswires) -- Broadcom ( AVGO ) and Microsoft ( MSFT )-backed (MSFT) OpenAI agreed to deploy 10 gigawatts of custom artificial intelligence accelerators, sending the chipmaker's shares rallying on Monday.

OpenAI will design the accelerators and systems that are slated for deployment by the semiconductor company beginning in the second half of 2026. Financial details of the coloration weren't disclosed.

"By designing its own chips and systems, OpenAI can embed what it's learned from developing frontier models and products directly into the hardware, unlocking new levels of capability and intelligence," according to a joint statement.

Broadcom's ( AVGO ) shares were up 10% intraday Monday, gaining 54% so far this year.

Last month, Broadcom ( AVGO ) Chief Executive Hock Tan told analysts on an earnings call that the company had secured more than $10 billion of orders of custom AI racks from a new customer. That customer was widely speculated to be OpenAI.

However, Charlie Kawwas, president of the semiconductor solutions group at Broadcom ( AVGO ), refuted that claim on Monday, telling CNBC that OpenAI was not the mystery customer.

The parent of generative AI chatbot ChatGPT recently entered into AI infrastructure deals with Nvidia ( NVDA ) , CoreWeave ( CRWV ) and Advanced Micro Devices ( AMD ) .

Nvidia ( NVDA ) intends to invest up to $100 billion in OpenAI to support a new partnership aimed at helping the AI lab expand its computing power. AMD agreed to deploy 6 gigawatts of its graphics processing units to power OpenAI's AI infrastructure, while AI cloud provider CoreWeave ( CRWV ) secured a contract worth up to $6.5 billion from OpenAI.
