OpenAI is set to file for an initial public offering (IPO) within days, targeting a September listing on the Nasdaq, according to a Wall Street Journal report cited by Yahoo Finance [23]. The news is corroborated by multiple financial outlets including Motley Fool [9][18] and Econotimes [104], and prediction markets show over 75% probability of an IPO before 2027 [106][108][112]. The offering is expected to be one of the largest in tech history, with potential valuation exceeding $1 trillion [109]. This IPO will provide OpenAI with substantial capital to fund its compute infrastructure and AI development, while offering public market exposure. The move comes amid heightened competition from Google and Anthropic [43][5], and follows a legal victory over Elon Musk [96]. The IPO filing represents a major liquidity event and signals OpenAI's transition from a private AI lab to a public company, likely accelerating its commercialization efforts. The guaranteed capacity offering launched concurrently [1] underscores OpenAI's strategy to lock in enterprise revenue ahead of the IPO.
