The company also announced in the release that it is developing a “unified AI superapp” and that its enterprise business will be as large as its consumer business by the end of the year.
The Wall Street Journal reported Tuesday that this is the largest funding round in Silicon Valley history. Bloomberg reported that OpenAI Chief Financial Officer Sarah Friar said the financing “blows out of the water even the largest IPO that’s ever been done.”
OpenAI said in its press release that the funding round was anchored by Amazon, Nvidia and SoftBank, and that there was continued participation from its long-term partner Microsoft.
The firm added that it raised over $3 billion from individual investors, having extended participation to them through bank channels for the first time, and that it will be included in several exchange-traded funds (ETFs) managed by ARK Invest.
In addition, OpenAI expanded its existing revolving credit facility to $4.7 billion. The facility is supported by a global syndicate and at close, remains undrawn, according to the release.
OpenAI is now generating $2 billion in revenue per month, up from $1 billion per quarter at the end of 2024, per the release.
“At this stage, we are growing revenue four times faster than the companies who defined the Internet and mobile eras, including Alphabet and Meta,” the company said in the release.
On the consumer side of its business, ChatGPT has 900 million weekly active users, has 50 million subscribers, and saw its ads pilot reach $100 million in annual recurring revenue (ARR) within six weeks.
“These are not just growth milestones — they show that frontier AI is becoming part of everyday life for people around the world,” OpenAI said in the release.
On the enterprise side, OpenAI’s application programming interfaces (APIs) now process more than 15 billion tokens per minute, and Codex serves 2 million weekly users. The company said its enterprise business now makes up 40% of its revenue and is set to reach parity with its consumer business by the end of the year.
OpenAI also said in the release that it is building a “unified AI superapp” that will bring together ChatGPT, Codex, browsing and agentic capabilities.
“Users do not want disconnected tools,” the company said in the release. “They want a single system that can understand intent, take action, and operate across applications, data and workflows.”
It was reported March 17 that OpenAI may launch an initial public offering (IPO) by the end of the year.
