What will OpenAI's annualized run-rate revenue (ARR) be at the end of June 2027, in USD billions?

From an August 2026 base run rate of ~$40 billion cnbc.com, reaching OpenAI's internal mid-2027 target of $62 billion requires ~4% compounded monthly growth. Our median estimate of $66.0 billion sits slightly above this target, acknowledging intense enterprise traction (coding tools and work products now boast 20 million weekly active users pymnts.com) and robust growth estimates for OpenAI's nascent advertising segment , while discounting naive extrapolation of summer hyper-growth. If management pushes aggressive gross-basis accounting ahead of a potential IPO, the printed run rate could stretch toward our 90th percentile of $92.0 billion. Conversely, the August 7 halt of the Astra model introduces execution risks openai.com. Factoring in this vulnerability in enterprise API market share—alongside a possible macro pullback in AI capex cnbc.com and basis risk if the resolution relies on audited GAAP revenue—anchors our left tail (P10) at $48.0 billion.
