A generation ago, a fast-growing company might list on a public exchange within four or five years of its founding. Today, that journey stretches far longer — and the consequences reach every investor, whether they realise it or not. Companies are staying private for longer than at almost any point in modern history, and a great deal of value creation has migrated with them.

The private detour

Abundant private capital, a preference for control, and the sheer cost and scrutiny of being public have all encouraged companies to postpone their debut. Many now reach multi-billion-dollar valuations while still private, and some of the most talked-about names of the past decade grew to enormous size — well into the tens of billions — before ever selling a public share.

By the time many companies list, the steepest part of the growth curve is already behind them.

Where the value moved

The implication is stark. In an earlier era, public-market investors could capture much of a company’s ascent. Increasingly, that ascent happens behind closed doors, and by the time a company lists, a large share of its growth has already been realised — by the private investors who were there earlier. Meanwhile, most exits are not blockbuster IPOs at all but acquisitions, often at valuations below $100 million, over holding periods that can stretch well beyond seven years.

The access problem

For most of this shift, private markets remained walled off — open to institutions, funds, and the already-wealthy, but out of reach for nearly everyone else. Structured vehicles have begun to change that, pooling investor capital so that individuals can participate in a single opportunity at accessible ticket sizes. It is a meaningful opening. It is also not a free lunch.

The trade-off

Private investing offers exposure to growth that public markets no longer fully capture. In return, it demands two things most public investments do not: a genuine tolerance for illiquidity, since capital is typically locked until an exit that may be years away, and an acceptance that any single early-stage position can go to zero. The disciplines that follow are old ones — diversify across many companies, and never commit money you may need soon.
