Where the value is created has moved
For most of the twentieth century, going public was an early milestone. A young, fast-growing company would list, and ordinary investors would ride the bulk of its growth alongside it. Amazon went public roughly three years after it was founded. Microsoft listed at around eleven. The public markets were where the compounding happened.
That has changed, and the shift is dramatic. The median company going public in 2024 was around 13 to 14 years old, compared with roughly four years old in 1999 and six years old in 1980. Companies now do the overwhelming majority of their growing while still private, funded by an enormous and deep pool of venture and late-stage private capital that simply did not exist a generation ago. They reach maturity, scale and often profitability before the public is ever invited in.
The consequence is straightforward but rarely stated plainly: the part of a company's life that produces the most spectacular returns now happens before it lists. When Amazon went public, almost all of its value creation was still ahead of it, in the public phase, available to anyone. When SpaceX lists, most of its value creation will be behind it, captured by the investors who backed it when it was private and risky.
The 2026 wave, in numbers
The current pipeline is unlike anything markets have seen. Goldman Sachs has projected that 2026 IPO proceeds could reach around 160 billion dollars, roughly a quadrupling of 2025 and beyond the previous record set in 2021. The headline names alone would account for an extraordinary share of that.
SpaceX is reported to be targeting a valuation in the region of 1.5 to 1.75 trillion dollars, which would make it the largest IPO ever, comfortably surpassing Saudi Aramco. OpenAI has been discussed at valuations above 750 billion dollars, and Anthropic, the maker of Claude, at figures ranging from roughly 350 billion to as high as 900 billion depending on the source and the round. The exact numbers vary widely across reports and are best treated as estimates that will move, but the order of magnitude is clear: three companies, well over three trillion dollars in combined value, arriving in a single window.
Why so little of it is actually for sale
Here is the mechanism that makes the point concrete. When a company is worth over a trillion dollars, it cannot float a normal proportion of its shares without overwhelming the market. So these mega-listings come with tiny free floats, in the region of 3 to 8 percent of the company. The other 90-plus percent stays exactly where it was: with the founders, employees, venture funds and late-stage private investors who held it before the IPO.
In other words, the public is being offered a thin slice of a company whose growth story is largely written, while the people who owned it through its formative, high-return years retain almost all of it. An IPO of this kind is less a fundraising event than a liquidity event: a carefully managed opportunity for early holders to begin realising gains, and to establish a public price for the vast private stake they keep.
The early sessions can be euphoric, which reinforces the illusion. When the chipmaker Cerebras listed recently, its shares jumped 68 percent on the first day, then fell about 10 percent the next. That pattern, a sharp pop followed by a giveback, is a recurring feature, not an accident: it is what it looks like when demand from public buyers meets supply from sellers who acquired their shares far lower and far earlier.
What this means for a long-term investor
None of this is a claim that public-market investing is a mistake, or that every IPO disappoints. Some of these companies will continue to compound impressively as public entities, and some IPOs raise genuine primary capital to fund real future growth rather than simply cashing out insiders. The public markets remain the foundation of almost every sensible portfolio.
But the 2026 IPO frenzy is the clearest illustration in years of a structural truth that sits at the centre of how the most sophisticated investors allocate capital: the access matters more than the enthusiasm. The returns being celebrated this year were earned by those who were positioned in private markets long before the listing. The lesson is not to chase the opening print. It is to ask whether your portfolio has any exposure to the phase where that kind of value is actually created.
The reframe
An IPO feels like a beginning. For the public investor, it is closer to an ending: the moment a company's most explosive growth, the part that rewarded patience and early conviction, is handed off to the market at a price that already reflects it. The excitement is real, but it points in the wrong direction. The companies are extraordinary. The opportunity to benefit from their rise the way their early backers did has, for the most part, already passed.
The bottom line
The largest IPO year in history is not a reason to buy IPOs. It is the loudest possible reminder of where modern value creation happens, and who gets to participate in it. The wealth being celebrated in 2026 was built quietly, over more than a decade, in private hands. For investors who want exposure to the next generation of these companies rather than a thin, late slice of the current one, the implication is not to wait for the bell. It is to be in the room before it rings.
