Investing in IPOs:
What 45 Years of Data Says
Across 9,343 U.S. IPOs (1980–2025), the typical newly public company lags the market over the following three years. The losses are not random: they cluster in the most expensive, least profitable, hype-driven deals.
01The base rate: IPOs underperform the market
Buying an IPO at the first-day closing price and holding for three years (1980–2024, 9,253 deals) returned +19.1% on average, but the market returned far more over the same windows.
02The richer the IPO, the worse the 3-year return
Among large IPOs (trailing revenue above $100M), sorting by price-to-sales ratio at the first-day close reveals a clean, monotonic penalty for paying up. The most expensive bucket is a wealth-destruction machine.
03Profits and scale matter more than the story
The IPO penalty is concentrated in unprofitable, tiny-revenue companies. Profitable, larger businesses roughly keep pace with the market.
04The first-day pop is a seller’s number, not a buyer’s
The famous IPO “pop” is money transferred from the issuing company to whoever got an allocation at the offer price. If you buy at the open, you have already missed it, and you are now exposed to the long-run underperformance.
05The price tag and the sponsor are signals too
Two things you can read straight off the prospectus carry real information: the offer price per share, and who is backing the company. Cheap shares and no institutional sponsor are among the worst combinations in the data.

09What the marquee tech IPOs actually cost
The marquee technology IPOs priced across an enormous valuation range, from about 2× sales (Nvidia) to nearly 95× (SpaceX). The pattern is striking: the greatest compounders ever — Nvidia, Microsoft, Apple — came public cheap and profitable, while SpaceX’s June 2026 listing at a ~$1.77T valuation is the most expensive of them all.
