ChatGPT developer OpenAI has secured $110 billion in fresh funding from a group of major technology firms led by Amazon, pushing the company’s pre-money valuation to $730 billion.

OpenAI co-founder and CEO Sam Altman said on Friday that Amazon has committed $50 billion to the round, while Nvidia and SoftBank will each invest $30 billion. He added that more investors may join as the funding process continues.

Amazon will initially invest $15 billion, with the remaining $35 billion to be released over the coming months under certain conditions.

Altman said the partnerships will help expand OpenAI’s global reach, strengthen infrastructure and improve financial stability, enabling the company to bring advanced AI tools to more users and businesses worldwide.

He noted that ChatGPT now has over 900 million weekly active users and more than 50 million paying subscribers. According to Altman, AI is entering a new stage where cutting-edge research is rapidly turning into everyday tools used at a global scale.

As part of a multiyear deal, OpenAI and Amazon will introduce new AI capabilities for enterprises, with Amazon Web Services becoming the exclusive third-party cloud provider for OpenAI Frontier. The two firms will also expand their existing agreement by $100 billion over eight years.

OpenAI said it is also deepening ties with Nvidia, while stressing that its long-standing partnership with Microsoft remains unchanged and central to its strategy.
