Mega IPOs and the AI investment cycle

SpaceX lays groundwork for sustained IPO recovery

I recently had the opportunity to listen to a compelling Franklin Templeton webinar on the next wave of mega initial public offerings (IPOs) – what’s driving them, what they mean for investors, and how they could reshape the structure of U.S. equity markets. Drawing on perspectives from across our investment teams, this was one of the most insightful discussions I have encountered on the topic. Here are my key takeaways.

The AI boom is reshaping capital markets – and private markets are where much of that story begins. AI as a theme is dominating financial markets, and the purest exposure to frontier AI labs remains in venture capital. This is driving fund flows into private markets that are, by any measure, truly unprecedented – including US$100 billion fundraising rounds that would have been unthinkable a few years ago.

The IPO market is no longer waiting for a catalyst – it has one. After a prolonged hiatus, the conditions for a sustained IPO recovery are falling into place. SpaceX’s debut served as an important bellwether – it went about as well as anyone could have hoped – and that success has likely given comfort to other companies weighing a listing. With over US$7 trillion sitting in money market accounts, there is no shortage of liquidity waiting to be deployed into compelling new offerings.

These are not your typical IPO candidates. What makes this cycle distinctive is the maturity of the companies coming to market. These are not early-stage ventures, but scaled businesses with significant revenues, large customer bases, and category leadership in high-growth segments. Companies are staying private longer, so they can navigate investment cycles and product transitions away from the scrutiny of quarterly reporting. They arrive in public markets at a far more advanced stage than they would have a decade ago.

The AI IPO boom could cannibalize its own winners. If several mega-cap IPOs come to market in the same window, they will compete for capital not only with each other, but with existing publicly traded growth stocks. That could create rotation pressure across software, semiconductors, fintech, and AI beneficiaries. This is a dynamic investors should monitor closely, even as overall demand remains robust.

The next wave of IPOs could reshape market leadership. Perhaps the most significant long-term implication is structural. Companies are preparing to list across AI, space, defense technology, fintech, automation, robotics, and data infrastructure. These new entrants may help diversify U.S. equity markets away from a small group of heavily concentrated mega-cap names – ultimately leading to a healthier market and more ways to express secular growth themes.

Public markets could provide greater transparency on AI’s return on investment. One of the most consequential effects of this IPO wave will be the financial disclosure it forces. For the first time, public investors may be able to assess whether AI companies are converting significant capital expenditures into revenue, and improving profitability. This matters enormously, particularly for semiconductors, where the durability of the current spending cycle has been a persistent question hanging over the entire sector.

Index inclusion dynamics are changing. SpaceX’s IPO set an important precedent: Index providers adjusted their rules to include a company early based on its scale and significance. We should expect this to continue. Future mega IPOs are likely to enter benchmarks at a size that can materially impact those benchmarks – and that has real implications for passive investors, active managers, and the broader distribution of returns across the shareholder base.

What are the risks? All investments involve risks, including the possible loss of principal. The value of investments can go down as well as up, and investors may not get back the full amount invested. Investing in the natural resources sector involves special risks, including increased susceptibility to adverse economic and regulatory developments affecting the sector. Special risks are associated with investing in foreign securities, including risks associated with political and economic developments, trading practices, availability of information, limited markets and currency exchange rate fluctuations and policies. Investments in foreign securities involve special risks including currency fluctuations, economic instability and political developments. Investments in emerging markets, of which frontier markets are a subset, involve heightened risks related to the same factors, in addition to those associated with these markets’ smaller size, lesser liquidity and lack of established legal, political, business and social frameworks to support securities markets. Because these frameworks are typically even less developed in frontier markets, as well as various factors including the increased potential for extreme price volatility, illiquidity, trade barriers and exchange controls, the risks associated with emerging markets are magnified in frontier markets. To the extent a strategy focuses on particular countries, regions, industries, sectors or types of investment from time to time, it may be subject to greater risks of adverse developments in such areas of focus than a strategy that invests in a wider variety of countries, regions, industries, sectors or investments.
