OpenAI's accelerated preparations to confidentially file its IPO prospectus in the coming weeks, with Goldman Sachs and Morgan Stanley, position the company for a potential September 2026 debut and underpin the 75.5% market-implied odds it will list ahead of Anthropic. Recent reports highlight OpenAI's focus on an earlier window amid strong artificial intelligence demand, while Anthropic continues advancing its own timeline toward an October or later Q4 2026 window, supported by fresh capital raises at roughly $900 billion valuation. Traders weigh these timelines against typical large-cap IPO execution risks, including market conditions and regulatory reviews, with OpenAI's recent momentum providing the clearest near-term edge in this competitive race between leading large language model developers.
