OpenAI has completed the largest private funding round, raising $122 billion ahead of its blockbuster initial public offering (IPO) expected to be launched by the end of this year.
The deal, which values the ChatGPT-maker at $852 billion, aims to support its costly push to manufacture more chips, build data centres, and hire talent as the artificial intelligence race heats up. The company’s valuation includes the money raised.
As part of the financing, the AI company raised more than $3 billion from big investors through banks. OpenAI also said that it will be included in several exchange-traded funds (ETFs) managed by ARK Invest, the investment firm led by well-known investor Cathie Wood.
Most of the funding, which had been in the works for months, came from three major tech companies. Amazon agreed to invest $50 billion in the round, while Nvidia and SoftBank each invested $30 billion.
However, a large portion of Amazon’s $35 billion investment will only come through if OpenAI goes public or achieves the technological milestone of artificial general intelligence, according to a report by AFP.
The AI giant also secured funding from a long list of other prominent investors, including Andreessen Horowitz, Abu Dhabi’s MGX, D.E. Shaw Ventures, TPG, and T. Rowe Price.
The AI developer has previously said it plans to spend more than $1.4 trillion on physical infrastructure in the coming years to support its AI software. To fund these plans, OpenAI and rival Anthropic PBC have raised capital from many of the same venture funds and tech companies, including their cloud and chip suppliers, such as Amazon and Nvidia.
OpenAI also said on Tuesday that it is currently generating $2 billion in monthly revenue. The company, which gained widespread attention as a product for everyday users, is also witnessing traction among business customers.
“OpenAI was the fastest technology platform to reach 10 million users, the fastest to 100 million users, and soon the fastest to 1 billion weekly active users. At this stage, we are growing revenue four times faster than the companies that defined the Internet and mobile eras, including Alphabet and Meta,” the company said in a blog post.
Enterprise sales now make up 40% of its revenue, the company noted, with that figure expected to increase to 50% by the end of this year.
Meanwhile, Amazon's investment in OpenAI also includes a cloud agreement to host and distribute OpenAI’s models for enterprise customers. That partnership will include a revenue-sharing agreement, though exact terms were not disclosed, AFP reported.
OpenAI has also stepped up efforts to boost revenue this year by introducing advertising in ChatGPT, an option that its chief executive, Sam Altman, had previously described as a “last resort.” The company, which has mainly relied on subscriptions, said its ads pilot program generated $100 million in annualised revenue within just six weeks.
