A broker request does not guarantee an allocation; a market purchase happens at the price available when your order executes, which can be very different from the IPO price. Before choosing either route, review the latest prospectus on SEC EDGAR.
How to invest in an IPO
An IPO, or initial public offering, is when a company sells shares to the public as it becomes publicly traded. For an individual investor, there are two distinct ways to seek shares: request an allocation before trading starts, or place a market order after the shares begin trading.

| Route | When you buy | Price | Main uncertainty |
|---|---|---|---|
| IPO allocation through a participating broker | As part of the offering, before public trading begins | Typically the offering price if shares are allocated | You may be ineligible or receive some or no shares; allocation is not guaranteed. |
| Purchase after listing | Once shares trade publicly | The market price when the order executes, not necessarily the offering price | Price and execution can change quickly, especially early in trading. |
Request an allocation through a broker
- Check whether your brokerage participates in that specific IPO and whether you meet its eligibility requirements.
- Ask the broker for the offering’s order instructions, deadline, available order types, fees, and any restrictions on selling allocated shares.
- Submit an indication of interest or order as the broker directs. It is a request, not a confirmed purchase.
- Wait for the broker to tell you whether shares were allocated and how many. The issuer and underwriters have broad discretion, and a customer may receive only a small part of the requested amount—or none.
Not every broker participates in every offering, and firms set their own procedures and eligibility rules. Investor.gov explains that individuals can have difficulty getting IPO shares and that brokerage eligibility varies: IPO share access and broker-dealer eligibility.
Buy after trading begins
If you do not receive an allocation—or prefer to wait—you can place an order through a broker once the stock is trading. This is a regular market purchase, not a purchase at the IPO price. The order may execute at a different price from the one you saw when placing it, depending on the order type and market movement. Ask your broker how its order instructions work; the SEC’s order-types bulletin was updated August 18, 2026: Understanding Order Types.

How the IPO price is set
Before an offering, underwriters gather indications of interest from potential investors into an order book, including how many shares they want and at what prices. They consider that demand alongside valuation work and market conditions, then negotiate terms with the company. The issuer ultimately determines the IPO price.
The offering price is a negotiated estimate, not a guaranteed value, a floor, or a prediction of where the stock will trade. It can differ substantially from the opening price and later prices. A first-day rise does not prove the company chose the best price for itself: it might have raised more at a higher offering price. A stock can also trade below its offer price. The SEC describes the process and its conflicts of interest in its IPO investor bulletin.
What to check in the prospectus
For a U.S. IPO, the company commonly registers the offering on Form S-1. The registration statement and prospectus can be amended during SEC review, so read the latest filing available and check the final prospectus when it is filed. Form 424B filings commonly contain final prospectuses. You can find company filings using the SEC’s EDGAR research guide.

- Risk factors: Read the risks management identifies in the context of the company’s business rather than dismissing them as standard legal language.
- Use of proceeds: Check whether the money goes to the company, selling shareholders, or both, and how the company says it intends to use its share.
- Selling shareholders and ownership: See how many shares existing holders are selling, how many they retain, and their relationships with the company.
- Underwriting or plan of distribution: Review underwriting terms and information relevant to pricing and distribution.
- Financial statements and operating metrics: Examine the disclosed financial history and business measures; do not assume an IPO company has a long public-reporting record.
SEC effectiveness means the registered offering may proceed. It is not SEC approval of the investment, a recommendation to buy, or a guarantee that the disclosures are complete or accurate.
Risks to understand before placing an order
Limited access and uncertain allocation
Access depends on whether your broker participates, its customer rules, and allocation decisions by the issuer and underwriters. A broker cannot promise that you will receive shares. Investor.gov’s eligibility guidance states that no brokerage firm can guarantee a customer will be able to purchase IPO shares: IPO eligibility at broker-dealers.
Price swings and early trading
The offer price may be far from the market price once trading begins. A buyer after listing may pay substantially more—or less—than the IPO price, and early trading can be volatile. A direct allocation may be at the offering price, but only if the broker grants one; it does not remove the company and market risks.
Temporary support and limited public float
Underwriters may engage in permitted activities that support a new issue’s trading price in its early days. If that support ends, the price may fall. Also check for restricted shares and lock-up agreements, which limit when certain holders can sell. The SEC says lock-ups are typically 180 days, but the actual terms vary by IPO. When restrictions expire, more shares may become eligible for sale and put pressure on the stock price. Read the specific prospectus rather than assuming a standard date applies.

An IPO company may have a limited history of public reporting. Assess the company’s actual financial disclosures and stated risks; registration is a disclosure process, not an endorsement of the business or its shares.
Pre-IPO solicitations and scams
An offer claiming to provide access to shares before a registered IPO is not the same as getting an allocation in that IPO. The SEC warns that pre-IPO pitches can involve social-media promotions, aggressive sales tactics, unregistered promoters, or misleading claims about timing and returns. Verify the offering’s registration status and the identity of the person making the pitch. See the SEC’s June 7, 2024 pre-IPO investment scams alert.

Neither route is universally safer. A direct allocation, if granted, may let you buy at the stated offering price, but getting shares is uncertain and a broker may limit eligibility or quick resale. Waiting means you can see the public market price, but that price may move sharply and may be higher or lower than the offer price. Compare the routes against your goals and circumstances rather than treating a first-day purchase as automatically safer.
