OpenAI is preparing to confidentially file a draft IPO prospectus as early as Friday [1].
This move signals a critical shift for the artificial intelligence sector as the industry's most prominent private companies compete for public market dominance. A successful listing would provide OpenAI with the massive capital required to maintain its lead in a resource-intensive market while setting a valuation benchmark for its rivals.
The filing is expected by Friday, May 22, 2026 [1]. This timing places OpenAI in a direct race with Anthropic, as both companies vie to be the first major AI firm to go public. The competition for public listing is not limited to AI; it coincides with a broader surge of high-profile tech entries into the stock market.
Among these is Elon Musk's SpaceX, which is targeting a valuation of nearly $2 trillion in its own IPO filing [2]. The clash between OpenAI and SpaceX carries additional weight given the ongoing legal and professional friction between the companies' leadership.
Market analysts expect a historic influx of capital from this cycle. The combined IPO wave involving OpenAI, Anthropic, SpaceX, Shein, and Kunlunxin could raise nearly $200 billion [3]. This wave represents one of the largest collective entries of private tech firms into the public sphere in a single period.
OpenAI's decision to file confidentially allows the company to keep its financial details private until shortly before the public offering. This strategy helps the firm manage market expectations and avoid premature volatility while it finalizes its transition from a private entity to a publicly traded corporation.

The potential public listings of OpenAI and Anthropic mark the transition of the AI boom from a venture-capital-funded experiment to a mature industrial phase. By going public, these companies will face unprecedented scrutiny regarding their revenue models and the actual profitability of large language models. Furthermore, the sheer scale of the projected $200 billion capital raise suggests that the public markets are still willing to bet heavily on AI and aerospace, despite the immense costs of scaling these technologies.
