OpenAI is preparing for a public debut, and its latest investor documents highlight a stark reality: the company's infrastructure strategy hinges heavily on a single partner. In filings reviewed by CNBC, the AI leader flagged its relationship with Microsoft as a material risk, noting the software giant provides a substantial share of financing and compute capacity.

Since 2019, Microsoft has poured $13 billion into OpenAI, securing a 27% stake now valued at $135 billion. While this partnership fueled early growth, OpenAI warns that terminating or modifying the agreement could severely impact operations. The company generated $13.1 billion in revenue last year and boasts 900 million weekly users, but scaling requires massive resources. OpenAI has committed roughly $665 billion toward compute and infrastructure through 2030.

Supply chain vulnerabilities remain a top concern for engineering leaders. The filings point to potential disruptions involving Taiwan Semiconductor Manufacturing Company, citing geopolitical tensions that could choke off GPU supplies. To mitigate this, OpenAI has begun diversifying beyond Azure, partnering with CoreWeave, Oracle, and Google Cloud to meet heavy demand.

Legal headwinds also persist alongside technical challenges. The document outlines ongoing litigation with Elon Musk's xAI and multiple wrongful death lawsuits alleging harm caused by chatbot interactions. Despite the risks, investors recently valued the company at $730 billion following a $110 billion funding round involving Nvidia and SoftBank.

While Sam Altman isn't explicitly named, the filing acknowledges dependence on key personnel. For engineering teams watching the IPO, the message is clear: even the biggest AI players face significant bottlenecks in capital, compute, and legal stability as they scale. The path to profitability requires navigating complex dependencies that go far beyond model architecture.
