OpenAI just shattered its own fundraising record. The maker of ChatGPT closed a $110 billion funding round — the largest private financing in history — led by Amazon, Nvidia, and SoftBank.
Amazon is the biggest backer at $50 billion, though $35 billion of that comes later once OpenAI hits certain milestones. Nvidia and SoftBank each contributed $30 billion. The round remains open, and more investors are expected to join.
The deal values OpenAI at $730 billion before the new money — nearly two and a half times what it was worth just a year ago when it raised $40 billion at a $300 billion valuation.
Amazon's investment comes bundled with a major strategic partnership. AWS becomes the exclusive third-party cloud provider for OpenAI's enterprise platform, and the two companies are expanding their existing cloud deal by $100 billion over the next eight years. OpenAI will also build custom AI models to power Amazon's consumer products.
Worth noting: Amazon already has billions invested in Anthropic — OpenAI's closest competitor. It's now backing both sides of the biggest rivalry in AI.
ChatGPT now has over 900 million weekly active users. The money isn't going into someone's pocket — it's going toward the chips, data centers, and infrastructure needed to keep up with that kind of scale.
CEO Sam Altman put it plainly: the world needs a lot of computing power, and OpenAI intends to build it.
At $730 billion, OpenAI is worth more than most countries' annual economic output. And the round isn't even closed yet.
