Nvidia will invest up to $100 billion in OpenAI as the AI lab builds data centers requiring 10 gigawatts of power capacity. The 10-gigawatt deployment equals 4 to 5 million GPUs -- the same number Nvidia will ship globally this year. Building one gigawatt of data center capacity costs $50 to $60 billion, including approximately $35 billion for Nvidia chips and systems. The first phase begins in the second half of 2026 using Nvidia's next-generation Vera Rubin systems. The investment adds Nvidia to OpenAI's investor roster alongside Microsoft, SoftBank, and Thrive Capital at a $500 billion valuation. Nvidia CEO Jensen Huang described the investment as "additive to everything that's been announced and contracted."Read more of this story at Slashdot.
