OpenAI's Valuation Soars to $500 Billion Amid AI Hype

Thu 2nd Oct, 2025

The valuation of OpenAI, a prominent player in the artificial intelligence sector, has reached an impressive $500 billion, equivalent to approximately EUR426 billion. This surge in valuation follows recent sales of employee shares to investors, as reported by Bloomberg, citing sources familiar with the matter. This represents a staggering increase of around $200 billion compared to the company's valuation during a funding round in April of this year.

With this latest milestone, OpenAI has reclaimed its position as the most valuable private company, surpassing other notable firms. Currently, SpaceX, the aerospace company founded by billionaire Elon Musk, ranks second with a valuation of approximately $350 billion, based on a recent stock buyback.

As the creator of ChatGPT, OpenAI has established itself at the forefront of AI chatbot technology while also offering various other AI tools, including those for automated image and video generation. Despite its significant growth, the company remains private, limiting access for potential investors. Reports indicate that OpenAI is considering a transition from its original nonprofit structure to a profit-oriented model, which has been a source of contention with Microsoft, a major investor. This shift could lead to Microsoft receiving equity in OpenAI, and the specifics of this arrangement have become a point of negotiation.

In addition to its ongoing discussions with Microsoft, OpenAI has recently secured substantial contracts with tech giants Nvidia and Oracle, amounting to hundreds of billions of dollars. However, some analysts express concerns regarding the sustainability of such massive investments in AI infrastructure, raising the possibility of a speculative bubble in the market. Prominent figures in the tech industry, including Meta's CEO Mark Zuckerberg and OpenAI's own CEO Sam Altman, have voiced their apprehensions about the potential for an investment bubble that may eventually burst.

As the landscape for artificial intelligence continues to evolve, the implications of OpenAI's growing valuation and its strategic decisions will be closely monitored by investors and industry analysts alike.
