NVIDIA (NVDA 181.66, +5.06, +2.87%) makes a sharp move into positive territory after the company and OpenAI announced a letter of intent for a landmark strategic partnership to deploy at least 10 gigawatts of NVIDIA systems for OpenAI's next-generation AI infrastructure to train and run its next generation of models on the path to deploying superintelligence.

The strategic partnership enables OpenAI to build and deploy at least 10 gigawatts of AI data centers with NVIDIA systems representing millions of GPUs for OpenAI's next-generation AI infrastructure. To support the partnership, NVIDIA intends to invest up to $100 billion in OpenAI progressively as each gigawatt is deployed. The first gigawatt of NVIDIA systems will be deployed in the second half of 2026 on the NVIDIA Vera Rubin platform.

Both the PHLX Semiconductor Index (+1.4%) and the broader information technology sector (+1.3%) move notably higher in response.
