Despite OpenAI CEO Sam Altman's assertion that the heart of the rivalry between his company and Anthropic centers on technological prowess rather than the timing of an initial public offering (IPO), The Wall Street Journal argues that securing the first-mover advantage in going public is equally vital. Presently, the U.S. stock market is experiencing a robust IPO window, with AI firms emerging as the primary beneficiaries. Anthropic has discreetly submitted its IPO application, boasting an estimated valuation of approximately $965 billion and is poised to debut as early as this autumn. OpenAI, too, is gearing up for a public listing, with a valuation pegged at $852 billion. With both companies nearing the $1 trillion valuation mark, they are intensely vying for capital market investments.

Leading the charge to go public not only grants a financial edge but also enables the company to shape industry financial disclosure norms and secure a prominent voice. Yet, this pioneering status comes with the risk of heightened market scrutiny, and subsequent entrants may encounter increased comparative pressure. Should SpaceX, Anthropic, and OpenAI all proceed with IPOs concurrently, it would present an unprecedented challenge to the funding dynamics of the U.S. stock market. Nonetheless, being the first to go public still confers strategic advantages, such as bolstering financial reserves and fostering team stability, which are crucial for long-term success in the competitive AI landscape.
