OpenAI Files Confidentially for IPO, Intensifying Race Against Anthropic

OpenAI confidential Initial Public Offering (IPO) filing today, hot on the heels of Anthropic, escalates an already blistering race between the generative AI titans to tap public markets and solidify their multi-trillion-dollar ambitions. The ChatGPT maker, last privately valued at $852 billion, is reportedly targeting a September 2026 debut, while its rival, Anthropic, which recently reached a $965 billion valuation, initiated its own confidential process just last week. This dual thrust towards Wall Street marks a pivotal moment for the AI industry, poised to test whether venture-fueled valuation can withstand public scrutiny. Anthropic, behind the Claude chatbot, is reporting annualized revenue exceeding $47 billion and recently achieved its first operating profit, showcasing rapid enterprise adoption. Meanwhile, OpenAI, despite its reported $25 billion annualized revenue, projects significant losses until at least 2029, raising questions about the sustainability of its growth model as both firms face immense compute infrastructure costs. The upcoming listings, potentially alongside Elon Musk's SpaceX, are set to define the 2026 IPO landscape, forcing investors to scrutinize true frontier AI economics for the first time. The simultaneous public debuts will offer an unprecedented side-by-side comparison of these rival AI giants, with market participants eagerly awaiting their detailed S-1 Registration Statement to gauge the viability of their stratospheric private market pricing.
