OpenAI IPO: Everything You Need to Know

OpenAI has confidentially filed for a US IPO as of June 2026, with reported valuations ranging from $500 billion to $1 trillion. The filing comes as the company generated approximately $13 billion in revenue during 2025 while burning through $34 billion in expenses, posting significant losses that will force scrutiny of its path to profitability.

The core investment question centers on unit economics: whether OpenAI can compress its massive compute and R&D costs into sustainable margins at scale. The company's 2025 spending of $34 billion against $13 billion in revenue reflects the capital-intensive nature of frontier AI development, where infrastructure and talent acquisition dwarf traditional software economics.

Public market appetite will hinge on whether investors assign OpenAI valuation multiples comparable to established mega-cap tech platforms or apply a discount for the uncertain timeline to profitability. At the high end of the $1 trillion valuation range, the company would debut among the largest US IPOs on record, requiring institutional buyers to underwrite a long-duration bet on AI model monetization.

The June 2026 timeline gives OpenAI roughly 18 months to demonstrate margin improvement or articulate a credible cost trajectory before roadshow presentations begin.
