To invest in an IPO, you need a brokerage account at a firm that’s part of the offering’s underwriting syndicate, enough assets to clear that firm’s eligibility threshold, and an indication of interest submitted before the subscription window closes. Even then, most retail investors who request shares in a popular deal receive only a fraction of what they asked for, because institutional buyers typically take around 90% of the shares.1Fidelity. IPO Share Allocation Process The rest of this article walks through each step, plus the rules that catch new IPO investors off guard.
Read the S-1 Before You Commit Anything
Every company going public files a Form S-1 registration statement with the SEC. Part I is the prospectus, and it’s the document you actually want. It contains audited financials, management’s discussion of performance, and a risk factors section covering business, legal, regulatory, financial, and stock-specific risks.
Read the risk section carefully. Companies have legal incentive to be thorough there, so it often surfaces problems the marketing materials smooth over. The prospectus also lists the proposed exchange, ticker symbol, and an estimated price range (something like $14 to $16 per share) that tells you roughly how much capital you’ll need to reserve. Pull S-1 filings from the SEC’s EDGAR database by searching the company name and filtering for registration statements.2U.S. Securities and Exchange Commission. Search Filings
Check Whether Your Brokerage Actually Offers IPO Access
Not every brokerage participates in every IPO, and the ones that do restrict access to clients who meet internal financial thresholds.3U.S. Securities and Exchange Commission. Initial Public Offerings: Eligibility to Get Shares at Broker-Dealers Firms commonly limit participation to clients in premium service tiers, clients with certain account balances, or clients who generate enough trading revenue.
Fidelity, for example, generally requires $100,000 or $500,000 in household assets depending on the deal, or membership in its Premium Services or Private Client Group, and it requires an indication of interest for at least 100 shares.4Fidelity. How to Participate in an Initial Public Offering (IPO) Thresholds vary across firms. A few platforms, including Robinhood and SoFi, have opened IPO access to a broader range of accounts. If IPO investing matters to you, check whether your current brokerage participates before an offering you want appears.
Restricted Persons Under FINRA Rule 5130
Even with an eligible account, federal rules may bar you from buying. FINRA Rule 5130 prohibits “restricted persons” from purchasing shares in new equity offerings. That group includes employees of broker-dealers, certain financial services professionals, and their immediate family members.5FINRA.

Submitting an Indication of Interest
Once you’ve confirmed your eligibility and picked an offering, go to the IPO or new offerings section of your brokerage’s platform. Active deals are listed with submission deadlines. Select the company to open the electronic order form.
The form asks for the number of shares you want, a price preference, and the total dollar amount you’re prepared to commit. A limit price caps what you’ll pay per share. A market price accepts whatever the underwriters set as the final offering price. Double-check the entries before submitting, because errors can invalidate the request.
Here’s what new IPO investors most often get wrong: an indication of interest is not a binding order. It’s a conditional, non-binding request. You’re telling the underwriters you want in; neither side is locked to anything yet. The prospectus itself typically says so. The non-binding structure exists because it’s illegal to sell a security while the registration statement is still under SEC review, so the indication only reserves your spot in line. After you submit, you’ll get a digital confirmation or tracking number. That confirms the request was received. Nothing more.
Final Pricing and the Reconfirmation Window
The underwriters set the final offering price on the evening before public trading begins, based on demand collected during bookbuilding. Sometimes the price lands inside the range printed in the prospectus. Sometimes strong demand pushes it above, or weak interest drops it below.
If the final price falls within the prospectus range, your indication of interest generally converts to a firm order automatically. If it lands outside the range, you have to manually reconfirm through your brokerage’s portal. That window can be very short, sometimes just a couple of hours the evening of pricing. Miss it and your request is canceled. This is where people lose deals they thought they had.
Once you reconfirm at the final price, the order is binding. Your brokerage pulls the required funds from your available cash, and you wait for shares to be distributed.
Why You Probably Won’t Get All the Shares You Asked For
Getting shares allocated is the hardest part of the process and largely outside your control. Underwriters split the offering between institutional and retail investors, with institutions historically receiving roughly 90%.1Fidelity. IPO Share Allocation Process The retail slice then gets divided among eligible clients at participating brokerages.
When an offering is oversubscribed, your brokerage decides who gets shares and how many. Firms generally prioritize clients with larger account balances, longer relationships, and higher service tiers. You may receive a fraction of what you requested, or nothing. Notifications arrive by account alert or email shortly before trading begins, and unused funds return to your cash balance.
After Shares Hit Your Account
Trading Doesn’t Start at the Opening Bell
Newly listed stocks often take an hour or more to begin trading. Recent Nasdaq IPOs have typically started somewhere between 11 a.m. and noon while the exchange’s designated market maker establishes a fair opening price from pre-market orders.7Nasdaq. New IPOs: Why Don’t They Start Trading Immediately After the Market Opens Federal rules also permit underwriters to stabilize the price during the first days of trading to prevent a sharp decline, though not to inflate it above the offering level.8eCFR. 17 CFR 242.104 – Stabilizing and Other Activities in Connection with an Offering Early price action isn’t purely organic.
Selling Quickly Will Get You Banned From Future IPOs
Nothing legally stops you from selling on day one, but your brokerage will penalize you for it. Selling shortly after receiving IPO shares is called flipping, and it triggers restrictions on future participation.
Policies vary. Fidelity imposes a 180-day ban from future IPOs for a first flipping offense, a 365-day ban for a second, and a permanent ban after a third.9Fidelity. IPO FAQ Robinhood counts a sale within 30 days as flipping and can block IPO access for 60 days.10Robinhood. About IPO Access Underwriters want stable shareholders, not day-one sellers adding pressure to the price.
Watch the Lock-Up Expiration
Company insiders (employees, founders, venture capitalists) are usually barred from selling for a set period after the IPO. Most lock-up agreements run 180 days, and the terms appear in the prospectus.11U.S. Securities and Exchange Commission. Initial Public Offerings: Lockup Agreements Expiration is the first moment a large block of shares becomes eligible for sale, and the resulting supply increase often pushes the price down. The drop tends to be temporary, with prices frequently recovering in the following weeks. If you’re holding IPO shares and the stock falls sharply about six months in, check the lock-up date.
Taxes on IPO Shares
IPO shares follow the same capital gains rules as any other stock. Sell within a year of your purchase date and the gain is short-term, taxed at your ordinary income rate, potentially as high as 37% for top earners. Hold longer than a year and you qualify for long-term capital gains rates.
For 2026, long-term capital gains rates are:
- 0% on taxable income up to $49,450 for single filers or $98,900 for married filing jointly
- 15% on taxable income up to $545,500 for single filers or $613,700 for married filing jointly
- 20% on taxable income above those thresholds
The rate gap sharpens the flipping tradeoff. A 30% gain on day one is smaller after ordinary-rate tax and a brokerage ban than it looks on paper. Holding at least a year gives you the lower rate and preserves future access, at the risk that the price drops in the meantime.
Direct Listings as an Alternative
Not every company goes public through a traditional IPO. In a direct listing, existing shareholders sell shares directly on an exchange without new stock issuance or underwriters. There’s no set offering price, no allocation process, and no built-in lock-up. You buy on the open market at whatever price the first day sets, with no chance to get in at a pre-determined offering price.12U.S. Securities and Exchange Commission. What Are the Differences in an IPO, a SPAC, and a Direct Listing
Access is simpler; price certainty is worse. Without underwriters managing the initial distribution, early trading can be volatile. You skip the eligibility hurdles but also skip any offering-price discount that traditional IPO participants might get.
