Mega-IPOs Poised to Reshape Public Markets and Economy

Nelson Griggs, president of Nasdaq’s Capital Access Platforms Division, has articulated how a new wave of mega-Initial Public Offerings (IPOs) is poised to reshape industries, the public stock market, and the global economy. This discussion, held with Fast Company senior writer Ainsley Harris at this year’s Innovation Festival, comes at a time when major technology firms are either preparing for or have recently undertaken significant public market entries. SpaceX, for instance, executed a record-breaking IPO in June. This event followed closely behind Anthropic, the developer of the AI model Claude, which announced its own proposed IPO with a potential valuation reaching $2 trillion, as reported by Bloomberg. OpenAI, the creator of ChatGPT, has also been on a similar trajectory, though recent concerns regarding AI safety risks have reportedly caused the company to pause its IPO plans, according to Fortune. Perplexity AI is another significant player in this trend, reportedly aiming for an IPO in 2028. These companies are entering the public market during a period where investor focus has been shifting towards privately held assets. Morgan Stanley data indicates that increased access to private capital has led to a decrease in the number of companies pursuing public listings. The total number of publicly listed companies in the U.S. has declined significantly from its peak of approximately 8,000 in 1996 to around 4,000. A key concern arising from these mega-IPOs is their potential to overshadow smaller companies that wish to go public. This concern is amplified by recent regulatory actions that have imposed stricter rules on “micro-cap IPOs,” following a series of alleged pump-and-dump schemes. However, Griggs suggests a more integrated view, stating that public and private markets should not be seen as mutually exclusive. He highlighted a substantial investor appetite for public market investments, while also acknowledging the rapid growth of the private market, which is expanding at three times the pace of public markets globally. This dynamic allows companies to remain private for longer, enabling them to build more robust businesses and be better positioned for a future public offering. SpaceX, as an example, operated as a private entity for 24 years before its stock market debut in June. Griggs also commented on the capital demands of AI development, suggesting that public markets could be enhanced to better support the substantial funding required for AI buildouts, and that private markets might need to adapt to facilitate this growth.
