Artificial intelligence company OpenAI has signed one of the largest cloud contracts in history, committing to purchase $300 billion worth of computing power over five years from Oracle.
The deal, reported by the Wall Street Journal, underscores the soaring cost of AI infrastructure. The agreement will require 4.5 gigawatts of capacity — equivalent to the power use of about four million homes.
The contract builds on OpenAI’s expanded partnership with Microsoft and Oracle in 2024, which gave it access to additional computing through Oracle Cloud Infrastructure (OCI) alongside Microsoft’s Azure AI.
The infrastructure will allow training on up to 64,000 NVIDIA GPUs or Grace Blackwell Superchips, supporting large-scale generative AI, natural language processing, and other advanced workloads.
The deal coincided with a surge in Oracle’s stock, lifting the fortune of co-founder Larry Ellison by $101 billion in a single day — the largest one-day gain ever recorded by Bloomberg’s Billionaires Index. Ellison, now worth $405 billion, overtook Elon Musk to become the world’s richest man.
