To trade IPOs as a retail investor, you open an account at a brokerage that receives allocations, confirm you’re not a restricted person under FINRA rules, submit a non-binding indication of interest during the marketing period, reconfirm your order once the final offering price is set, and then either hold the allocated shares or sell them under rules that can penalize quick selling. It’s a different process from buying a listed stock, with pre-qualification, a narrow confirmation window, no guarantee of a fill, and post-trade restrictions that matter as much as the purchase itself.
Whether You’re Eligible to Buy
Two gates stand between you and an IPO allocation. The first is federal, the second is set by your brokerage.
FINRA Restricted Persons
FINRA Rules 5130 and 5131 bar certain people from buying shares in a new equity offering. The restricted list includes broker-dealer employees, anyone with authority to buy or sell securities for a bank or investment company, and portfolio managers at institutional firms.1FINRA. Restrictions on the Purchase and Sale of Initial Equity Public Offerings Immediate family members are also restricted if there’s a material support relationship. Rule 5131 separately prohibits “spinning,” where an underwriter allocates shares to executives at companies the firm wants as investment banking clients.2FINRA. Regulatory Notice 19-37 Every brokerage will ask you to attest that you’re not a restricted person before letting you participate.
Brokerage Minimums
The account requirement varies dramatically by firm. Fidelity requires $100,000 in household assets for certain offerings and $500,000 for most others, though members of its premium service tiers can bypass the asset threshold.3Fidelity.

About IPO Access SoFi requires only a self-directed investment account with no minimum balance, plus a suitability questionnaire.5SoFi. Am I Eligible for IPO Investing
The tradeoff is real. The lead underwriter controls how shares are distributed across brokerages, and firms with larger allocations tend to prioritize their wealthiest clients. Low-minimum retail platforms typically receive smaller allocations, so your odds of getting shares are lower even after you qualify.
Placing an Indication of Interest
You don’t submit a normal buy order for IPO shares. You submit an indication of interest, which is a non-binding request for a certain number of shares at or below a maximum price you specify. Underwriters compile these indications into an order book that helps them gauge demand and recommend a final offering price to the company.6SEC.gov. Investor Bulletin: Investing in an IPO Most platforms also ask whether you’ll accept a partial fill.
Because the indication is non-binding, neither side is committed. You can withdraw it, and the brokerage can decline to allocate any shares regardless of your request.
Before deciding how much to request, read the preliminary prospectus. It’s filed with the SEC as part of Form S-1 and available for free through the EDGAR database.7SEC.gov. Accessing EDGAR Data The preliminary version carries an estimated price range but not the final price, which is set only after the underwriters have gauged demand. Pay close attention to the risk factors and the “Use of Proceeds” section. If a large portion of the raise is going to pay off debt or cash out existing shareholders rather than fund growth, that tells you something about what’s driving the offering.
Reconfirming After Pricing
Once the underwriters set the final offering price, your brokerage will typically require you to reconfirm that you still want the shares at that price. The reconfirmation window is short, often just a few hours, and platforms notify you by email or app alert when it opens. Miss it and your indication is cancelled. The step exists because the final price can land well above the preliminary range, and a fresh commitment protects both you and the brokerage from orders placed under different pricing assumptions.
How Shares Get Allocated
Reconfirming doesn’t guarantee you’ll receive your full request, or any shares at all. When an offering is oversubscribed, brokerages ration their allocation across eligible investors.
Most brokerages rank customers by assets and the revenue those accounts generate, so clients with larger and longer-standing relationships get higher priority.8Fidelity. IPO Share Allocation Process Premium-tier members are generally eligible for every offering the firm participates in, while customers who meet only the minimum threshold may receive partial fills or nothing. Some retail platforms use a lottery for heavily oversubscribed offerings, giving each eligible participant an equal shot at a smaller allocation.
You’ll get a notification confirming how many shares (if any) landed in your account. Your cost basis equals the offering price, not whatever the stock opens at on the exchange.
Trading on the First Day
The morning an IPO begins trading, you cannot place a standard market order to buy additional shares. Only limit orders are accepted before the stock begins actively trading, because there is no established market price yet and a market order could fill at a wildly unexpected level. Once continuous trading opens, market orders and other order types become available.
The first 30 minutes tend to be the most volatile, with heavy volume as institutional buyers, retail traders, and short-term speculators compete for price discovery. The opening price can differ substantially from the offering price in either direction. That early movement reflects the mechanics of a market finding its footing, not a verdict on the company.
What You Can and Can’t Do With the Shares
Flipping Penalties
Brokerages enforce their own anti-flipping policies to discourage investors from selling allocated shares immediately after trading begins. The specifics vary by firm. Some restrict you from future IPO participation for 60 days if you sell within 30 days of the offering; others impose longer penalties or collect fines. These aren’t federal regulations. They’re brokerage-level rules designed to protect the firm’s relationship with the underwriter. If you flip, the underwriter takes note, and your brokerage may lose future allocations as a result.
The Research Quiet Period
For at least 10 days after an IPO, analysts at the underwriting firms are prohibited from publishing research reports or making public appearances about the newly listed company.9FINRA. Research Analysts and Research Reports The quiet period is intended to prevent underwriters from using analyst coverage to boost the stock right after the offering. An exception applies for significant news events if the firm’s compliance department approves. The restriction does not apply to offerings by emerging growth companies.
Lock-Up Expirations
Company insiders, employees, and large shareholders typically sign lock-up agreements that prevent them from selling for a set period after the IPO. Most last 180 days, though terms vary, and the company must disclose them in its registration documents.10U.S. Securities and Exchange Commission. Initial Public Offerings: Lockup Agreements Even if you’re not subject to a lock-up yourself, the expiration matters. Stocks often dip around lock-up expiry as previously restricted shares hit the market.
Taxes When You Sell
The IRS doesn’t treat IPO shares as a special category. What matters is how long you held them and what profit or loss you realized.
Short-Term Versus Long-Term Gains
Sell within one year of receiving your shares and the profit is a short-term capital gain, taxed at your ordinary income rate, which can reach 37% at the top bracket. Hold longer than a year and the gain qualifies for long-term capital gains rates of 0%, 15%, or 20%, depending on your taxable income and filing status.11Internal Revenue Service. Topic No. 409, Capital Gains and Losses For single filers in 2026, the 0% rate applies on taxable income up to roughly $49,450, the 15% rate covers income up to about $545,500, and the 20% rate kicks in above that.
High earners face an additional 3.8% net investment income tax on capital gains when modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly.12Internal Revenue Service. Topic No. 559, Net Investment Income Tax A high-income investor who flips IPO shares within a year could face a combined federal rate above 40% on the gain.
Wash Sales
If you sell IPO shares at a loss and buy back the same stock within 30 days before or after the sale, the IRS treats it as a wash sale and disallows the loss deduction. The disallowed loss gets added to the cost basis of the repurchased shares, so you don’t lose it permanently, but you can’t use it to offset gains in the current tax year.13Internal Revenue Service. Case Study 1 – Wash Sales The rule matters more with IPOs than people expect. If the stock drops below your offering price, the instinct to sell for the tax loss and immediately buy back cheaper is strong, and the wash sale rule neutralizes that move.
If You Received Shares Before the IPO
Most retail investors who buy at the offering price through a brokerage are not affected by SEC Rule 144. But if you received shares through employment at the company or a pre-IPO investment, they’re restricted securities. For companies that file regular SEC reports, you must hold the shares for at least six months before selling.14eCFR. 17 CFR 230.144 – Persons Deemed Not to Be Engaged in a Distribution For non-reporting companies, the holding period is one year. Rule 144 also imposes volume limits on affiliates (officers, directors, and major shareholders), who can sell only a limited number of shares during any rolling three-month period.
Direct Listings and SPACs Work Differently
Not every company goes public through a traditional IPO, and the process for retail investors changes with the path.
In a direct listing, a company becomes publicly traded without issuing new shares and without using underwriters. Existing shareholders sell their shares directly to the public on the exchange.15SEC.gov. What Are the Differences in an IPO, a SPAC, and a Direct Listing There’s no allocation process and no indication of interest. You buy on the exchange once trading opens, using standard order types.
A special purpose acquisition company (SPAC) raises money through its own IPO, then uses those funds to acquire a private company, taking the target public through a merger. SPAC investors buy in before a target is identified. Sponsors typically receive about 20% of the common stock at a steep discount, which creates a potential conflict of interest since they profit when any deal closes. If you bought at the SPAC’s IPO, you can redeem your shares for the offering price plus accumulated interest before the acquisition closes. If the SPAC doesn’t find a target within its window (usually 18 to 24 months), it dissolves and returns the trust funds to shareholders.16FINRA. Investing in a SPAC
