Rising valuation and expanding ambitions bring new scrutiny to OpenAI’s core partnerships
OpenAI, the company behind ChatGPT, has acknowledged a critical vulnerability in its business model, warning prospective investors that its deep reliance on Microsoft could pose a significant risk to its long term stability. The disclosure appears in a financial filing resembling an IPO prospectus reviewed by CNBC, signaling a new level of transparency as the company prepares for a potential public listing.
This development comes at a time when OpenAI is experiencing unprecedented growth. The company recently closed a massive funding round of $110 billion, backed by major players including Amazon, Nvidia, and SoftBank. With additional efforts underway to secure another $10 billion in commitments from a broader investor base, OpenAI’s valuation has surged to an estimated $730 billion. This rapid ascent reflects the explosive adoption of artificial intelligence tools since the launch of ChatGPT in late 2022.
Heavy reliance on Microsoft raises concerns over operational independence
At the center of OpenAI’s risk disclosure is its strong dependence on Microsoft, which has invested approximately $13 billion in the company since 2019. Microsoft currently holds a 27 percent stake in OpenAI’s non profit arm, which was valued at $135 billion as of October last year.
Beyond financial backing, Microsoft also provides a substantial portion of OpenAI’s computing infrastructure through its Azure cloud platform. This partnership has been instrumental in enabling OpenAI to scale its services globally. However, the company now admits that such dependence creates a potential single point of failure.
The filing explicitly states that any changes in Microsoft’s support, including modifications or termination of agreements, could adversely impact OpenAI’s operations. The company also cautions that failure to diversify its infrastructure and partnerships could further amplify this risk.
Partnership and competition define a complex relationship
Despite their close collaboration, the relationship between OpenAI and Microsoft is not without competitive tension. In its 2024 annual report, Microsoft listed OpenAI among its competitors, alongside major technology firms such as Amazon, Apple, Google, and Meta.
This dual dynamic of cooperation and competition highlights the evolving nature of the artificial intelligence industry, where companies often collaborate on infrastructure while competing on products and services.
To mitigate these risks, OpenAI has already begun expanding its network of partners. The company is working with alternative cloud providers including CoreWeave, Google, and Oracle to handle the growing demand for computing power.
Multiple risk factors underscore challenges ahead
In addition to its reliance on Microsoft, OpenAI has outlined several other risks that could impact its future trajectory.
One of the most significant concerns is capital intensity. The company has committed an estimated $665 billion toward computing infrastructure through 2030, with spending expected to increase as demand for AI services continues to grow. This level of investment underscores the resource heavy nature of advanced artificial intelligence development.
Geopolitical exposure also remains a critical issue. OpenAI depends heavily on semiconductor supply chains, particularly manufacturers like TSMC. Ongoing tensions between China and Taiwan could disrupt these supply lines, posing a serious threat to the company’s ability to sustain its operations.
Legal challenges add another layer of uncertainty. OpenAI is currently facing multiple lawsuits, including three cases filed by Elon Musk’s AI venture xAI, as well as at least 14 lawsuits in California alleging harm linked to ChatGPT. These cases could have financial and reputational implications depending on their outcomes.
Finally, OpenAI’s organizational structure presents a unique challenge. Operating as a public benefit corporation under the OpenAI Foundation, the company must balance profit driven objectives with broader societal goals. While this model aligns with its mission, it may complicate decision making and investor expectations.
Strong growth metrics support IPO ambitions
Despite these risks, OpenAI’s growth metrics remain exceptionally strong. The company reports approximately 900 million weekly active users and generated $13.1 billion in revenue in 2025. These figures position OpenAI as one of the most influential players in the global technology landscape.
The acknowledgment of Microsoft dependence as a risk factor is described by OpenAI as a standard legal disclosure. However, it also reflects a broader reality: the company’s success is closely tied to partnerships that must be carefully managed as it scales.
As OpenAI moves closer to a potential IPO later this year, investors will likely scrutinize how effectively the company can balance its reliance on key partners while building a more diversified and resilient ecosystem.
A defining moment for the AI industry
OpenAI’s candid disclosure marks an important moment not just for the company, but for the artificial intelligence sector as a whole. It highlights the challenges of building cutting edge technology at scale, where access to capital, infrastructure, and global supply chains can determine success or failure.
In an industry driven by rapid innovation and intense competition, the ability to manage strategic dependencies may prove just as critical as technological breakthroughs.
