IPO stocks are shares in a company that is selling to the public for the first time. Before the initial public offering, ownership sits with founders, employees, and early investors, and there is no open market for those shares. On the day of the offering, the company sells a block of newly standardized shares at a set price to investors who were allocated an allotment in advance, and the stock then begins trading freely on an exchange where anyone with a brokerage account can buy or sell.
What Changes When a Company Goes Public
A private company’s equity is usually held by a small group, and each sale is negotiated one deal at a time. After an IPO, that equity is split into standardized shares that change hands thousands of times a day. Public shareholders gain voting rights on major corporate decisions and become eligible for dividends if the company pays them.
Insiders don’t get to cash out on day one. Most IPOs include a lock-up agreement that prevents founders, employees, and venture capitalists from selling their shares for a set period, and the SEC notes that terms vary but most lock-ups run 180 days.1U.S. Securities and Exchange Commission. Initial Public Offerings, Lockup Agreements The lock-up terms are disclosed in the registration documents, so investors know when a wave of insider selling could hit.
The company also takes on a disclosure obligation it didn’t have before. Once the SEC declares the registration statement effective, the company is subject to ongoing reporting requirements under the Securities Exchange Act, meaning regular financial statements, executive compensation reports, and public filings any investor can read.2U.S. Securities and Exchange Commission.

The Main Paths a Company Takes to List
Traditional Underwritten IPO
The most common route uses investment banks as underwriters. The banks review the company’s finances, help set the offer price, and sell shares to their network of institutional buyers. Underwriters commit to buying the shares and reselling them, and in exchange they collect fees that historically run between 5% and 10% of the offering value. They also run the roadshow, where executives present to large institutional investors and money managers to build demand before trading opens.
Direct Listing
A direct listing skips the underwriter. Existing shareholders sell their stock straight onto the exchange, and the market sets the opening price from that morning’s buy and sell orders. No new shares are created, so the company doesn’t raise fresh capital through the listing itself. The SEC notes that companies choosing this path tend to have strong brand recognition, since without underwriters generating interest, the company needs enough name value to attract buyers on its own.3U.S. Securities and Exchange Commission. Types of Registered Offerings
SPAC Merger
A special purpose acquisition company is a shell entity with no real business operations. It raises money through its own IPO with the sole goal of merging with a private company within a set timeframe. When the merger closes, the private company takes the SPAC’s place on the exchange. If the SPAC fails to complete a deal in time, it must return the money to its investors. SEC rules adopted in 2024 now require more extensive disclosures from SPACs to better protect investors.4SEC.gov. Final Rules: Special Purpose Acquisition Companies, Shell Companies, and Projections
Dutch Auction
In a Dutch auction, the company collects bids from all interested investors instead of letting the underwriter set the price. Each bidder submits how many shares they want and the maximum they’ll pay. Shares are allocated from the highest bid down, and every winning bidder pays the same clearing price: the lowest accepted bid. Google’s 2004 IPO is the best-known example. The trade-off is a smaller first-day price jump, since the auction tends to set a price closer to what the market actually values the company at.
How Shares Get Priced and When Trading Starts
An IPO doesn’t happen overnight. Several months usually pass between the initial filing and the first trade, and the sequence explains why the price you pay depends heavily on when you buy.
Before filing, the company enters a quiet period. Federal securities law prohibits public statements that could hype the coming offering. The company can announce that it plans to issue securities and continue sharing routine business information, but anything that looks like conditioning the market is off-limits. The point is to keep investors focused on the formal registration documents rather than marketing.
The company then files its registration statement (Form S-1) with the SEC. Staff reviewers examine the document and may ask for revisions or additional disclosures. This review commonly takes 75 to 120 days, and the company cannot sell shares until the SEC declares the registration statement effective.2U.S. Securities and Exchange Commission. Going Public
While the review is underway, the company and its underwriters run the roadshow: presentations by senior management to prospective investors, primarily large institutional buyers and money managers. Retail investors are rarely invited. Feedback from those meetings plays a major role in setting the final offer price. Once the SEC gives the green light and the price is set, shares begin trading on the exchange.
How to Buy IPO Shares
Getting shares at the offering price is harder than buying stock on a normal day. Allocations are made before the stock starts trading, and retail investors are not first in line. The mechanics vary by brokerage but the shape is similar.
Most brokerages require you to meet eligibility thresholds before they’ll even let you request IPO shares. Fidelity, for instance, requires either $100,000 or $500,000 in household assets depending on the offering, or membership in its premium client tiers.5Fidelity. How to Participate in an Initial Public Offering Some newer platforms have lower bars. Robinhood uses a lottery, where each eligible customer’s request has the same chance of being filled regardless of how many shares they asked for.6Robinhood. About IPO Access
If you qualify, you submit a conditional offer to buy, specifying how many shares you want at the offering price. Because demand routinely exceeds supply, you may receive a partial allocation or nothing at all.6Robinhood. About IPO Access The day before trading starts, there’s typically a confirmation window (at least 60 minutes on Robinhood’s platform) to adjust or cancel. After that window closes, your conditional offer becomes a binding purchase.
If you miss the allocation, you can still buy shares on the open market once trading begins. The catch is that the first-day market price is often well above the offer price. A standard brokerage account is enough, and you can place a market or limit order like you would for any other stock.
What the Prospectus Tells You
The Form S-1 is the single most important document for anyone evaluating an IPO. It contains audited financial statements covering several years of operating history, a description of the company’s business model, its competitive position, and exactly how the company plans to spend the money it raises.2U.S. Securities and Exchange Commission. Going Public That last detail matters more than most investors realize. A company planning to invest in product development tells a different story than one using IPO proceeds to pay off debt or cash out early investors.
The risk factors section deserves close attention. SEC regulations require the company to describe the most significant factors that make the investment speculative, and each risk must have its own descriptive heading. Vague boilerplate risks that could apply to any company are supposed to be pushed to the end of the section, so the company-specific risks at the top are the ones worth reading carefully. If the risk factor section runs longer than 15 pages, the company must include a bulleted summary of the principal risks at the front of the prospectus.7eCFR. 17 CFR 229.105 – Item 105 Risk Factors
Every S-1 filing is free through the SEC’s EDGAR database at sec.gov.8U.S. Securities and Exchange Commission. Search Filings Search by the company’s name or ticker to find the prospectus. Reading even the summary, the risk factors, and the use-of-proceeds section gives you a stronger foundation than any news article about the company.
Risks Specific to IPO Investing
IPOs get attention because they feel exciting, which is exactly why they deserve extra caution. Several dynamics work against retail investors in ways that aren’t always visible.
The information gap is the biggest one. Institutional investors who attend the roadshow get direct access to management presentations and can ask questions. Retail investors only see the prospectus. They can’t reach the same private information no matter how much online research they do, so the people setting the price know more than the people paying it.
First-day price pops look like easy money and often aren’t. Research on IPOs from 1980 through 2003 found average first-day returns of about 19%, but those gains went overwhelmingly to institutional investors who received allocations at the offer price. Retail investors buying at the inflated opening price paid a premium. During the dot-com bubble, IPOs with first-day returns above 300% went on to lose an average of 95% of their value from the first closing price through the end of 2002.
Lock-up expiration is a predictable pressure point. When the 180-day lock-up ends and insiders are free to sell, the sudden increase in available shares can push the price down.1U.S. Securities and Exchange Commission. Initial Public Offerings, Lockup Agreements The date is in the prospectus, so there’s no reason to be surprised by it.
Flipping an IPO allocation quickly can also carry consequences at your brokerage. Some firms restrict access to future IPOs for investors who sell within the first few weeks. The specific holding period and penalties differ by firm, so check the policy before treating an allocation as a short-term trade.
How IPO Profits Are Taxed
IPO shares follow the same capital gains rules as any other stock, and the deciding variable is how long you hold before selling.
Sell within a year of purchase and the profit is a short-term capital gain, taxed at your ordinary income rate, which can reach 37% for top earners. Hold for more than a year and the gain qualifies as long-term, taxed at 0%, 15%, or 20% depending on your taxable income.9IRS. Topic No. 409, Capital Gains and Losses For 2026, single filers with taxable income up to $49,450 pay 0% on long-term gains, the 15% rate applies up to $545,500, and gains above that threshold are taxed at 20%.
The temptation to sell an IPO stock quickly is strong. A first-day 30% pop can feel like free money, but cashing out inside a year means paying nearly double the rate you’d owe if you held a bit longer. The math doesn’t always favor waiting, but the tax gap is wide enough that it belongs in the decision.
A 3.8% net investment income tax also applies to individuals with modified adjusted gross income above $200,000 ($250,000 for married couples filing jointly). This surtax sits on top of the capital gains rates, taking the effective maximum to 23.8% for long-term gains and 40.8% for short-term.9IRS. Topic No. 409, Capital Gains and Losses
