OpenAI has closed a $110 billion funding round — the largest private tech fundraise ever recorded — more than double the size of its last raise a year ago, which was itself a record for a private tech company.
The round consists of $50B from Amazon, $30B from Nvidia, and $30B from SoftBank, against a $730B pre-money valuation. Additional investors are expected to join before the round closes at the end of March.
The capital isn't passive. Each investor secured strategic infrastructure partnerships alongside their checks:
Amazon ($50B) — Amazon's largest investment ever in any company. AWS becomes the exclusive third-party cloud provider for OpenAI's enterprise platform Frontier, and OpenAI will expand its existing $38B AWS agreement by an additional $100B over eight years.
Nvidia ($30B) — OpenAI locks in 5 gigawatts of next-generation Vera Rubin capacity for training and inference, deepening its reliance on Nvidia's hardware ecosystem.
SoftBank ($30B) — Chairman Masayoshi Son's second major OpenAI commitment, following his $30B contribution in March 2025.
ChatGPT now has more than 900 million weekly active users and more than 50 million consumer subscribers. The funding is aimed squarely at scaling infrastructure to meet that demand.
For context on the competitive landscape: Anthropic closed a $30B Series G on Feb. 12 at a $380B post-money valuation. Google continues building Gemini internally. Meta is open-sourcing its models. OpenAI is betting that infrastructure scale — not just model quality — determines who wins the enterprise AI market.
Amazon completed that $50 billion commitment on July 31, and its market cap topped $3 trillion for the first time on August 3.
