OpenAI Raises $110 Billion in Largest Private Funding Round in History

OpenAI has closed a $110 billion funding round — the largest private financing in tech history — pushing its post-money valuation to $840 billion. The deal was backed by three mega-investors: Amazon ($50 billion), Nvidia ($30 billion), and SoftBank ($30 billion).

Key Highlights

• $110 billion raised in a single round, shattering all previous records
• $840 billion post-money valuation ($730 billion pre-money)
• Amazon leads with $50 billion ($15 billion initial + $35 billion conditional)
• Nvidia and SoftBank each contribute $30 billion
• 900 million weekly active ChatGPT users, over 50 million paid subscribers

Infrastructure Expansion

The funding comes with massive infrastructure commitments. OpenAI is expanding its partnership with AWS, with a projected $100 billion commitment over 8 years — bringing the total combined AWS partnership value to $138 billion. The company plans to utilize approximately 2 gigawatts of Trainium capacity on AWS.

Under the deal, AWS becomes the exclusive third-party cloud provider for OpenAI Frontier (stateful environments), while Microsoft Azure remains the exclusive provider for stateless OpenAI APIs.

What the Money Is For

CEO Sam Altman stated the goal is to "expand our global reach, deepen our infrastructure, and strengthen our balance sheet" while delivering "frontier AI to more people, more businesses, and more communities worldwide."

The capital will fuel:

• Scaling compute infrastructure to support next-generation models
• Expanding the OpenAI Frontier enterprise platform
• Strengthening the company's balance sheet ahead of a potential 2026 IPO
• Deepening partnerships with cloud and hardware providers

Context and Competition

The round dwarfs OpenAI's previous record — a $40 billion raise in March 2025 at a $300 billion valuation. In just one year, OpenAI's valuation has nearly tripled.

The funding also intensifies the AI arms race. Anthropic recently closed a $30 billion Series G at a $380 billion valuation, while Google continues pouring billions into its Gemini AI efforts. The combined AI infrastructure spending by Big Tech is expected to exceed $670 billion in 2026.

What's Next

With 900 million weekly active users and over 50 million paid subscribers, OpenAI is now the most valuable private company in the world. Industry observers anticipate a potential IPO later in 2026, which would be one of the most significant public offerings in tech history.

The round remains open, and OpenAI expects additional investors to join in the coming weeks.
