To buy IPO stock, you open an account at a brokerage that is part of the deal’s selling group, review the company’s registration statement, submit a non-binding indication of interest for the shares you want, and then confirm your order in a short window after the underwriters set the final price the evening before trading begins. The mechanics are the same at every firm; what changes is who qualifies and how the shares get rationed when demand outruns supply.
Check Whether You’re Eligible to Participate
Before account balances or paperwork, federal rules decide whether you can buy at all. FINRA Rule 5130 bars certain categories of people from purchasing shares in a new issue, including broker-dealers, owners and employees of broker-dealers, portfolio managers, and finders or fiduciaries connected to the offering.1FINRA.org. Restrictions on the Purchase and Sale of Initial Equity Public Offerings Immediate family members who receive material financial support from a restricted person, or provide it, fall under the same prohibition.
FINRA Rule 5131 addresses a related practice called spinning, where underwriters allocate IPO shares to executives of other companies in exchange for future investment banking business.2FINRA.org. New Issue Allocations and Distributions If you’re an executive officer or director of a company that has done or is doing investment banking business with the underwriter, you may be ineligible for that particular deal. Every brokerage that offers IPO access will make you certify you’re not a restricted person before accepting your request.
One boundary worth flagging: most large, high-profile IPOs are fully registered public offerings open to non-accredited investors. Accredited investor status matters mainly for smaller offerings or private placements structured before a full public listing. If you’re going after a well-known IPO, you almost certainly don’t need to clear a net worth or income test.
Open an Account With a Brokerage in the Selling Group
Underwriters distribute IPO shares only through their own clients or partner firms. If your brokerage isn’t part of the selling group for the deal you want, you can’t get an allocation there, no matter how big your balance is. Which brokerage to use is really a question of which deals that firm carries.
Account minimums vary widely. Fidelity requires at least $100,000 in household assets for certain follow-on offerings and $500,000 for most IPOs.3Fidelity Investments. IPO Share Allocation Process Robinhood’s IPO Access program has no stated minimum balance requirement, though the same FINRA restrictions on industry professionals still apply.4Robinhood. About IPO Access SoFi similarly allows any member with an active investing account to participate with no account minimums.5SoFi. Invest in IPOs – How to Buy IPO Stock Whichever platform you choose, the account has to be fully funded and approved for equity trading before you can submit anything.
Read the Preliminary Prospectus
Once you have access to a deal, pull up the company’s registration statement. It’s filed as Form S-1 with the SEC and available through the EDGAR database. Part I is the prospectus itself, with the business description, audited financial statements, risk factors, and management’s discussion of financial performance.6Legal Information Institute. Form S-1 Part II holds supplementary information the SEC doesn’t require the company to disclose publicly.
The initial S-1 is a preliminary prospectus, sometimes called a red herring. It shows you the financials, the risks, and how the company intends to use the money, but it typically does not include the final offering price or the exact number of shares being sold. Those numbers arrive in an amended filing after the underwriters gauge investor demand through the roadshow. Read the risk factors closely. That section is the closest thing you’ll get to the company telling you what could go wrong.
Submit an Indication of Interest
With the prospectus reviewed, go to your brokerage’s IPO portal and submit an indication of interest. You specify how many shares you want or a dollar amount, and you acknowledge that you’ve received and reviewed the preliminary prospectus.3Fidelity Investments. IPO Share Allocation Process This is not a binding order. It tells the brokerage and the underwriters you’re interested, and the underwriters aggregate these indications across the selling group to help set the final price.
Your account needs enough cash or margin capacity to cover the purchase at the top of the estimated price range. Some brokerages will reject your indication if it doesn’t. Don’t leave funding to the last day of the indication period. Transfer delays can cost you the window entirely.
Confirm Your Order After Final Pricing
Between the initial filing and SEC clearance of the registration statement, the company and underwriters are limited in what they can say publicly. The SEC and courts read the word “offer” broadly during this period, covering any communications that might generate public interest in the issuer or its securities.7Investor.gov. Quiet Period That’s why you won’t see the CEO doing media interviews or the company posting promotional content about the stock during this stretch.
After clearance, the underwriters set the final offering price, usually the evening before trading begins, using demand gathered from the roadshow and indications of interest. Your brokerage will then notify you, typically by email or platform message, that you need to confirm your order at the actual price. The confirmation window is narrow, often just a few hours. Miss it and your indication of interest is canceled automatically. This is where a lot of first-time IPO investors lose their allocation. They submit the initial request and then aren’t watching for the confirmation.
How the Allocation and Settlement Work
Confirming doesn’t mean you’ll get everything you asked for. When an IPO is oversubscribed, and popular ones almost always are, the brokerage allocates fewer shares than requested. Firms evaluate and rank customers based on their assets and the revenue they generate for the firm, with significant, long-term relationships typically receiving higher priority.3Fidelity Investments. IPO Share Allocation Process Ask for 500 shares and you might get 50, or nothing.
Once allocation is confirmed, funds come out of your cash account to settle the trade. Most equity transactions now settle one business day after the trade (T+1), but IPO shares from firm commitment offerings priced after 4:30 PM Eastern, which covers most IPOs, settle on a T+2 basis.8U.S. Securities and Exchange Commission. Shortening the Securities Transaction Settlement Cycle Cash leaves your account two business days after pricing, not instantly.
Don’t Flip the Shares
Selling your IPO shares right after trading opens is called flipping, and it can get you banned from future offerings. FINRA Rule 5131 defines flipping as selling new issue shares within 30 days of the offering date.2FINRA.org. New Issue Allocations and Distributions When customers flip, the managing underwriter can impose a penalty bid on the syndicate, which allows the underwriter to reclaim the selling concession from the brokerage that distributed those shares. Your broker loses money when you flip, which is why they take it personally.
Brokerages layer their own penalties on top of that. Fidelity defines flipping as selling within 15 calendar days of the start of secondary market trading, and applies escalating consequences:9Fidelity Investments. IPO FAQ
- First offense: a 180-day ban from future IPOs
- Second offense: a 365-day ban
- Third offense: a permanent ban from the IPO process
Other brokerages have similar policies with different timeframes. If your plan is to buy the IPO and dump it on day one, you’ll get to do it once at that firm.
Buying After Trading Begins
If you didn’t get an allocation, or didn’t try for one, you can still buy the stock on the secondary market. Just don’t expect your order to fill at 9:30 AM. New listings on Nasdaq run through a dedicated process called the IPO Cross, separate from the regular opening cross used for existing stocks.10Nasdaq. New IPOs – Why Dont They Start Trading Immediately After the Market Opens
The IPO Cross begins with a display-only period of at least 10 minutes, during which the exchange disseminates imbalance information and an indicative clearing price every second. After that, the lead underwriter works with the exchange during a pre-launch period, with no defined time limit, to determine whether additional price discovery is needed before opening the stock for trading.11Nasdaq Trader. The Nasdaq IPO Cross A new listing might not begin trading until late morning or afternoon.
When it does open, expect large swings. The opening trade price often differs substantially from the IPO offering price, sometimes by 30% or more in either direction. Use a limit order rather than a market order. A market order fills at whatever the best available price happens to be, which during the volatile first hours of a new listing could sit far above where you meant to buy. A limit order sets a ceiling and only executes if the price meets it.
One thing to know about the days after the open: underwriters often support the price. They typically hold an overallotment option, the greenshoe, that lets them purchase up to 15% more shares from the company to cover short positions they’ve created. If the stock drops below the offering price, they buy in the open market to prop it up; if it rises, they exercise the overallotment instead. The SEC requires this stabilization activity to be disclosed in the prospectus, along with an acknowledgment that it “may have the effect of raising or maintaining the market price” above where it would naturally trade.12U.S. Securities and Exchange Commission. Excerpt from Current Issues and Rulemaking Projects Outline The support typically lasts about 30 days. After it ends, the price reflects real supply and demand for the first time.
