OpenAI files confidentially for IPO, following Anthropic

OpenAI has confidentially filed for an initial public offering, according to the report. The move comes just over a week after rival Anthropic also filed to go public, intensifying the race between two leading AI labs.

The filings suggest the generative AI sector is moving from private capital-fueled growth toward public market scrutiny. If both listings proceed, investors may soon get a clearer view into the economics, infrastructure costs, and competitive pressures shaping frontier AI companies.
