Anthropic's ARR Tops $65B, Overtaking OpenAI as Fall IPO Looms

Bloomberg first reported on August 18 that Anthropic told investors its annualized revenue run rate exceeded $65 billion as of end-July, up roughly 38% from $47 billion in May and more than 7x its end-2025 level of just over $9 billion. Its most recent full quarter posted preliminary revenue above $11.5 billion, about 14x the prior year's $787 million, along with its first positive adjusted operating profit. The Information and other outlets say an IPO could launch as soon as this fall. Leakers claim its July ARR has overtaken OpenAI's roughly $40 billion, signaling strong commercialization momentum and imminent capital-markets action.

Confirmed

• Bloomberg: ARR above $65 billion at end-July, over 7x end-2025; @kimmonismus and @ChrisGPT relayed the roughly 7x multiple-month growth
• Latest full quarter preliminary revenue above $11.5 billion, 14x the prior-year $787 million and more than double Q1; @MeerAIIT and @thesaraharminta relayed the same figures, and the quarter marked Anthropic's first positive adjusted operating profit
• The Information reported the IPO could launch as soon as this fall; CNBC followed with the same $65B run rate; @AiBreakfast added the IPO is expected in September or October with Morgan Stanley, Goldman Sachs and JPMorgan among underwriters
• @ChrisGPT and @brucemacv noted the run rate annualizes the last 28 days of consumption revenue, so a single high-usage month can skew it, and it is not audited revenue
• On August 19, @GavinSBaker noted a chart showing combined OpenAI and Anthropic revenue accelerated month-over-month and year-over-year in July, and speculated Anthropic may have shifted ARR reporting from gross to net, making the $65B figure more conservative than the $47B — a common pre-IPO practice

Unconfirmed

• A unit discrepancy: some posts by @Kr00ney and @gaganghotra cited $6.5 billion instead of $65 billion, likely a transcription error (another @Kr00ney repost corrected it to $65B)
• The "overtaking OpenAI" claim comes from leaker accounts like @rohanpaulai and @ns123abc comparing ARR figures (OpenAI's $40B attributed to Greg Brockman); the two companies may use different calculation methods, and neither has officially confirmed it
• The IPO timeline remains media-reported, not company-confirmed; @AlanG888888's cited $190 billion 2028 revenue forecast is speculation; @GavinSBaker believes the leak aims to bolster the IPO roadshow and argues Anthropic is losing edge share to OpenAI, open source, and Grok — a personal view echoed by Elon Musk via @elonmusk, who also suggested the $65B figure was leaked
• @AccBalanced relayed analysis urging scrutiny of the composition and durability of revenue within the huge ARR (e.g., custom contracts); @signulll raised the debate over Anthropic's shift from AI-safety lab to commercialization-focused IPO candidate

Why it matters

• A $65 billion run rate means Anthropic may have significantly closed or even overtaken the revenue gap with OpenAI
• @firstadopter commented that despite some investor disappointment over slowing growth, the pace remains staggering, while cautioning against extrapolating monthly acceleration indefinitely
• The first positive adjusted operating profit suggests growth is beginning to come with improving profitability
• If the IPO launches this fall, media say it could target the largest IPO in history, making it one of the most watched AI listings
