An initial public offering, or IPO, is the process by which a private company sells shares to public investors for the first time, converting itself into a publicly traded company with a ticker symbol and a daily market price. The company raises capital, early investors and employees get a path to sell their stakes, and the public gets a new stock to buy. The headlines usually focus on the first-day price pop; the mechanics behind that number are where the real risk and reward live.
This is general information about how IPOs work, not personalized financial advice. IPO shares carry meaningfully higher volatility and uncertainty than established public companies, so treat any specific figures you see elsewhere as something to verify, not assume.
What changed in 2026
- IPO volume has been uneven, with windows of strong issuance followed by quiet stretches tied to broader market volatility — check current-year data before assuming the market is "hot" or "cold."
- Direct listings and SPAC mergers remain alternate paths to public markets, alongside the traditional underwritten IPO, each with different pricing and lockup mechanics — see the comparison with SPAC vs traditional IPO.
- Retail-focused IPO access platforms have expanded, letting more individual investors request an allocation before the stock opens, though allocations still tend to favor institutional accounts.
How the IPO process works
- The company hires underwriters, usually a group of investment banks, to manage the offering.
- A roadshow pitches the company to institutional investors, gathering feedback on demand and price.
- Underwriters set an IPO price, aiming to balance what the company wants to raise against what the market is likely willing to pay.
- Shares are allocated, mostly to institutional clients of the underwriters, before the stock opens for public trading.
- The stock begins trading on an exchange, where its price is set by open-market supply and demand, which can differ sharply from the IPO price within minutes.
Who actually gets shares at the IPO price
This is the detail that trips up most first-time IPO investors: the advertised "IPO price" is what institutional and select brokerage clients pay before the stock opens. Most retail investors buy after trading begins, at whatever the open-market price happens to be, which can be well above — or occasionally below — the IPO price. A few brokerages offer limited retail allocation programs, but availability and eligibility vary by firm and by deal.

Risks specific to new listings
New listings often carry a lockup period, typically 90 to 180 days, during which company insiders and early investors cannot sell their shares. When the lockup expires, a burst of selling frequently follows, which can pressure the price even if the business is performing fine. New listings also tend to have thinner trading history, less analyst coverage, and less predictable earnings patterns than seasoned public companies, all of which add volatility.
FAQ
Can any investor buy shares at the IPO price?
Generally no. IPO-priced shares are allocated mostly to institutional investors and select brokerage clients before the stock opens; most individual investors buy on the open market afterward.
Why do IPO stocks often jump or drop sharply on day one?
The IPO price is set ahead of trading based on estimated demand, while the opening trade reflects real-time market demand, which can diverge quickly, especially for high-profile deals.
What is a lockup period?
A window, commonly 90 to 180 days, during which insiders and early investors are contractually restricted from selling shares. Its expiration is a known event that can move the stock.
Is buying an IPO riskier than buying an established stock?
Generally yes, due to limited trading history, higher volatility, and less analyst coverage. That does not make it a bad investment automatically, only one that carries more uncertainty to weigh.
