Why companies are staying private longer

A generation ago, a fast-growing venture-backed company reaching a meaningful scale would typically IPO within five to eight years of founding. Today, many of the most valuable private companies in the world — SpaceX, Stripe, ByteDance among them — have stayed private for well over a decade, some approaching two, at valuations that would have made them among the largest listings of their era had they gone public. This isn't one or two outliers. It's a structural shift, and it has a specific, identifiable set of causes.

Private capital got deep enough to make an IPO optional

The most important change is the simplest: there's now enough private capital available at enough scale that a company no longer needs to go public to raise the money it needs. Growth equity funds, sovereign wealth funds, crossover hedge funds, and mega-round venture funds now routinely write checks in the hundreds of millions to low billions of dollars — capital that used to be exclusively available through public markets. A company that once had no choice but to IPO to fund its next stage of growth today often has several private options.

Secondary markets solved the liquidity problem IPOs used to own

Historically, the IPO wasn't just a fundraising event — it was the liquidity event, the one moment employees and early investors could finally sell. As secondary markets and structured tender programs matured (see how a secondary deal works), that function has been substantially replicated privately. A company like SpaceX running a scheduled tender roughly twice a year has, in practice, built a private substitute for the liquidity an IPO would otherwise provide — without giving up any of the control that comes with staying private. Remove the liquidity problem, and one of the strongest historical reasons to IPO on any particular timeline disappears.

Regulatory and compliance costs of being public have grown

Since Sarbanes-Oxley in the US and equivalent regimes elsewhere, the ongoing compliance burden of being a public company has increased substantially — internal control audits, expanded disclosure requirements, and greater personal liability exposure for executives and directors. None of this is prohibitive for a company that wants to be public, but it does raise the bar for "public is clearly worth it," particularly for companies that can access the capital they need privately anyway.

Founders and boards have more leverage to set the terms

In a market with abundant private capital chasing a limited number of top-tier growth companies, founders and existing investors have gained real negotiating leverage over when — or whether — to go public. Multiple well-known founders have said publicly that they see no urgency to list while private capital remains available on attractive terms and the business doesn't need the specific benefits a public listing provides. That's a meaningfully different posture than a decade or two ago, when going public was closer to an assumed inevitability once a company reached scale.

Public-market scrutiny of growth-stage losses has tightened

Public investors became notably less tolerant of large, sustained losses at scale following the 2021–2022 correction in high-growth public equities. Companies still burning significant cash to fund growth have found private markets more patient than public ones on that specific point — public markets increasingly want to see a credible path to profitability before they'll support a premium valuation, which pushes some companies to wait until that path is clearer before listing.

What this means going forward

None of this means IPOs are disappearing — they remain the cleanest path to full, permanent liquidity and public-market capital access, and plenty of companies still choose that path deliberately (see Nubank andGoTo). But the decision has shifted from "when" to "whether, and on what timeline that suits us" — and the secondary market is a direct beneficiary of that shift, because it's what makes staying private for a decade-plus actually workable for everyone holding equity in the meantime.
