The number of publicly traded U.S. companies has fallen by more than half since 1996 even as the economy tripled in size. Fewer than 4,000 companies now trade on U.S. exchanges compared with more than 8,000 three decades ago.

Headline-grabbing offerings from SpaceX, OpenAI and Anthropic have sparked talk of an IPO comeback this year and next. But those listings are exceptions that prove a rule which has been hardening for years.

The Shrinking Public Market

The instinct is to treat the IPO drought as cyclical tied to interest rates or investor sentiment. The data tells a different story.

In 1980 the median company went public with roughly $64 million in revenue adjusted for inflation today that figure would make it a mid-cap public company a generation ago.

Companies stay private far longer than they used to liquidity that shareholders once expected within years now stretches into decades if it arrives at all.

Why This Matters

Thousands of private companies generate $50 million to $200 million in annual revenue with steady growth margins and operating history they would have formed the backbone of public markets decades ago today most will never list.

Employees at these firms accepted below-market salaries and equity instead of cash expecting an exit within five to seven years instead they face tax bills from exercising options without any clear way to sell shares secondary markets remain opaque fragmented and slow according to Caplight data shows that 90% of all venture secondary volume last quarter was concentrated in just 15 companies.

A small number of prominent companies run tender offers giving employees structured opportunities to sell shares for everyone else brokered secondary marketplaces work slowly if at all only for the most sought-after names.

The pattern has repeated through every rate cycle bull market and recovery waiting for historical norms to return is not a strategy it is a bet against three decades of structural change.
