$40B into the furnace: As OpenAI adds a million users an hour, the race for enterprise AI dominance hits a new gear

In a move that surprised the tech industry Monday, OpenAI said it has secured a monumental $40 billion funding round led by SoftBank, catapulting its valuation to an unprecedented $300 billion — making it the largest private equity investment on record. The landmark investment underscores the escalating significance of AI, and also signals a shift in the enterprise technology landscape. With such a vast war chest, OpenAI now has much more staying power in its battle to serve companies with sophisticated generative AI solutions — where it is going against giant competitors like Google and AWS, as well navigating a sensitive relationship with its partner Microsoft. It is also facing tough competitors like Anthropic and Elon Musk’s xAI. Before this round closed, questions remained around whether OpenAI had the capital to continue to play in the big leagues.

Spending by companies on generative AI is expected to hit $644 billion this year, according to research company Gartner. That’s 76 percent more than was spent last year, and shows why the race is on among large companies to grab market share.

In its announcement, Open AI said it now has 500 million active weekly users, a significant jump from the 400 million number it cited just a month ago. With such viral growth, the company badly needed capital to build the servers and other infrastructure to keep up with this demand. It also shows that the intense competition, where other providers such as Google, Anthropic and even Chinese companies like DeepSeek are offering AI models that often match the functionality of OpenAI’s own leading models, has not slowed OpenAI’s growth rate.

In another significant twist Monday, OpenAI also announced that it planned to launch an open-weights reasoning model, and that it would allow developers to run it on their own hardware, the departure from OpenAI’s cloud subscription model that has so far driven its revenue.

The funding details: a closer look

For decision-makers navigating this rapidly evolving environment, understanding the implications of OpenAI’s latest financial maneuver is important. The $40 billion infusion came primarily from SoftBank, with contributions from Microsoft, Coatue, Altimeter, and Thrive Capital, according to reporting by CNBC. The capital is earmarked for OpenAI’s AI research, computational infrastructure, and enhancing its suite of AI tools, including the widely adopted ChatGPT, according to OpenAI’s post on the news. Notably, $18 billion of this funding is allocated to the Stargate project — a joint venture between OpenAI, SoftBank, and Oracle — aimed at developing extensive AI infrastructure.

The reports also suggested that the latest OpenAI funding would come in several tranches, and that part of it depends on OpenAI turning into a for-profit company by the end of this year.

While OpenAI is still driving a significant loss, the company projects that it will make enough revenue to break even by 2029 and then start making significant profits.

CEO Sam Altman tweeted Monday morning that the company had added “one million users in the last hour,” contrasting it with the million added in the five days after ChatGPT launched 26 months ago. The latest viral surge of usage comes from the big update OpenAI made last week to its image generating technology, which has taken image creation to a whole new level of ease and sophistication — with consumers going crazy making selfies in the style of Studio Ghibli. Notably, OpenAI announced Monday that it was restoring its offer to allow free users to access the new image generating technology, something it had taken back temporarily last week after usage overwhelmed the company’s servers.

While a lot of excitement around OpenAI remains on the consumer side, for enterprise technology leaders the funding development also carries big implications: OpenAI’s bolstered resources will help it fast-track the development of advanced AI models and products for enterprise as well, allowing it to stay ahead amid increased competition. Enterprises should anticipate a continued flurry of new AI-driven solutions, necessitating continued vigilance among enterprise companies to stay on top of these releases in order to remain competitive.
