OpenAI and Anthropic, two leading artificial intelligence companies, are preparing for initial public offerings (IPOs). The $2 trillion SpaceX IPO demonstrated high investor enthusiasm for AI companies, with shares rising from the $135 IPO price to top $200 before falling back. Both companies have made their ‘S1 filings’ in America, but no exact timeline has been announced, with estimates ranging from this autumn to the beginning of 2027. OpenAI initially planned to follow SpaceX in late summer or early autumn, but reports indicate executives including CEO Sam Altman decided it is still too early for the best possible outcome. OpenAI is targeting a valuation of over a trillion dollars and is wary of timing the market while investor appetites recover from the SpaceX deal and its volatility. It has also been reported that OpenAI revenues are not yet high enough to secure its desired valuation but may be by next year. Anthropic is still expected to push ahead with its IPO soon, with October suggested as the likeliest timeframe. Buying shares in either company would offer a direct way to profit from the AI boom, as both companies are already generating billions of dollars in subscription fees from services like ChatGPT and Claude.
