OpenAI notched its first $1 billion revenue month in July, finance chief Sarah Friar said in a CNBC interview, underscoring the rapid growth that has followed the late-2022 debut of ChatGPT. The company expects to nearly triple revenue this year to about $12.7 billion and recently crossed $10 billion in annual recurring sales. Friar warned, however, that OpenAI remains "constantly under compute," citing insatiable demand for graphics-processing units and data-center capacity. To ease the shortfall, the company is investing in massive facilities under the Stargate program and broadening supply agreements with providers such as Oracle and CoreWeave. Looking beyond its own needs, Friar said OpenAI is studying whether to rent out its AI-optimized infrastructure to other businesses, likening the prospective offering to the early days of Amazon Web Services. The idea could create a new revenue stream but is on hold while the firm secures capacity for internal workloads. OpenAI’s partnership with Microsoft "is changing," Friar added, yet she expects the software giant to remain a key collaborator for years. Funding the next phase will require new capital structures: Chief Executive Officer Sam Altman has signaled spending "trillions" on data centers, and Friar said the company is weighing debt, other novel instruments and, eventually, an initial public offering.
