Amazon committed $50B, with Nvidia and SoftBank each contributing $30B; OpenAI also extended participation to retail investors through bank channels for the first time, raising an additional $3B. Proceeds will fund the Stargate project, a joint data-center build-out with Oracle and SoftBank across the US. OpenAI is generating $2B in monthly revenue, serves over 900M weekly ChatGPT users, and is targeting an IPO by end of 2026.
