Chipmaker Nvidia will invest $100 billion in OpenAI as part of a partnership announced Monday that will add at least 10 gigawatts of Nvidia AI data centers to ramp up the computing power for the owner of the artificial intelligence chatbot ChatGPT. Per the letter of intent signed by the companies, the first gigawatt of Nvidia systems will be deployed in the second half of 2026. Nvidia and OpenAI said they would be finalizing the details of the arrangement in the coming weeks. The Nvidia-OpenAI partnership comes about 10 days after OpenAI said it had reached a new tentative agreement that will give Microsoft a $100 billion equity stake in its for-profit corporation. The parents of the 16-year-old California boy, who died in April, sued OpenAI and its CEO, Sam Altman, last month.
