OpenAI has just completed a fundraising of 122 billion dollars, for a post-money valuation of 852 billion. This figure is impressive, but above all it says one simple thing: in 2026, AI will now attract capital of almost industrial size.
In brief
- OpenAI has just taken AI into another financial category.
- The valuation of 852 billion is based on an already real domination of use.
- The next battle will be less about growth and more about justifying this value.
A lift that changes scale
OpenAI did not sign a classic financing round. On March 31, 2026, the company finalized a fundraising of $122 billion. Amazon, Nvidia and SoftBank are among the strategic partners, while Microsoft has continued its participation.
This detail matters because the money isn't just for a popular product. OpenAI now presents its model as an infrastructure layer for AI, with massive requirements for chips, clouds and data centers. Its architecture already relies on several partners, including Microsoft, AWS, Oracle, Google Cloud and Nvidia.
This is why the markets are following this issue closely. When so many giants inject so much capital into a single private company, it is no longer a bet on a trend. It is a life-size test of the real economic value of AI.
ChatGPT is no longer just a featured product
OpenAI can defend this valuation by traction that has become unusual. The company says ChatGPT now exceeds 900 million weekly users and 50 million subscribers, with monthly revenue of $2 billion. On this scale, we are no longer talking about a viral tool, but a global distribution network.
Another important signal is that the growth driver no longer comes only from the general public. OpenAI says that the company already represents more than 40% of its revenues and could join the consumer segment by the end of 2026. Clearly, the shift towards professional uses is already underway.
This is probably the heart of the matter. Investors aren’t just buying ChatGPT’s current audience. They buy into the idea that OpenAI can become the workplace interface of tomorrow, both for writing, coding, searching, automating and executing.
The real subject remains the cost of AI
This story is not a straight line, however. OpenAI raises so much because cutting-edge AI is extremely expensive to train, serve and maintain. The company had exceeded $25 billion in annualized revenuebut at the same time, it continues to invest at a very heavy pace to support its growth
We are also seeing a more disciplined logic appear on the monetization side. The advertising test launched in ChatGPT has already exceeded $100 million in annualized revenue in six weeks, a sign that OpenAI is looking for new levers beyond subscriptions and the API.
The point of tension is therefore clear. The larger the company grows, the more it must prove that it knows how to transform its technical domination into a sustainable economic machine. In artificial intelligence, size attracts money, but it also makes the bill bigger.
