Learning how to invest in IPOs using trading apps starts with understanding that access is not automatic. Most brokerage apps that advertise "IPO access" still require an eligible account, a nonbinding request for shares called an indication of interest, and an allocation that isn't guaranteed. This guide walks through the exact mechanics — from meeting eligibility requirements to placing an order after shares are allocated or the stock begins trading — so you know what actually happens at each stage before you commit any capital.
Who Can Participate? Brokerage Eligibility Requirements for IPO Access
Not every brokerage account qualifies for IPO participation, and not every IPO is opened to retail investors at all. Two eligibility layers apply. The first is regulatory: under FINRA Rule 5130, broker-dealers cannot sell new-issue shares to "restricted persons," a category that includes broker-dealer employees, finders, certain portfolio managers, and their immediate family members. Firms typically require an IPO eligibility certification confirming no restricted person holds a beneficial interest in the account (FINRA, Rule 5130).
The second layer is firm-specific. Brokerages that offer IPO access commonly set minimum account balance or trading-activity thresholds before a customer can even submit interest. Fidelity, for example, states that participation in traditional IPOs generally requires a minimum of $100,000 in eligible assets (or $500,000 for certain offerings), calculated weekly across retail accounts under the same Social Security number, with exceptions for certain premium service tiers (Fidelity, IPO FAQ). Other commission-free apps market broader "IPO access" with lower or no stated asset minimums, but the underlying regulatory suitability review — assessing income, net worth, objectives, and risk tolerance — still applies at every firm (SEC Investor.gov, Investor Bulletin: Investing in an IPO). Because eligibility rules vary by broker and by offering, always confirm the specific requirements inside your own app before assuming you qualify.
How to Invest in IPOs Using Trading Apps: The Process Step by Step
Once eligibility is confirmed, the actual mechanics of how to invest in IPOs using trading apps follow a consistent sequence across most brokerages, even though app names and interfaces differ. The five steps below cover the period before pricing, the allocation decision, and what happens once the stock is trading.
Step 1: Confirm Brokerage Eligibility and Complete Required Certifications
Before an app will even display an upcoming offering as available to you, it typically requires a completed IPO eligibility certification and, in many cases, a minimum balance or account-activity threshold. This step also confirms you are not a restricted person under FINRA Rule 5130. Skipping or ignoring this certification is the most common reason retail investors discover, too late, that a listed IPO was never actually available to their account.
Step 2: Submit an Indication of Interest
The second gate in how to invest in IPOs using trading apps is expressing interest itself. During the marketing period, after a preliminary prospectus has been distributed, the brokerage opens a window for customers to submit an indication of interest (IOI) — a nonbinding request specifying the maximum number of shares you would consider buying at the eventual offering price. You can typically increase an indication of interest up until the window closes and decrease or cancel it before shares are allocated (SEC Investor.gov, Investor Bulletin: Investing in an IPO). An indication of interest is not a purchase order and does not guarantee shares; some firms also require you to affirmatively confirm your interest again after final pricing, or you forfeit eligibility for that allocation round.
Step 3: Understand How Share Allocations Work
This is the step that most often surprises first-time participants learning how to invest in IPOs using trading apps: submitting interest does not mean you will receive shares. Underwriters typically allocate the large majority of shares to institutional investors, with only a minority carved out for retail distribution through participating brokerages — Fidelity has noted that roughly 90% of shares in a typical IPO go to institutional investors, with about 10% available to individual investors, though the split varies by deal (Fidelity, IPO FAQ). When retail demand exceeds the shares set aside, brokerages allocate what they receive using methods such as pro-rata distribution relative to account size and relationship, or a randomized lottery process, rather than "first come, first served." Allocations are generally communicated the morning after pricing, often before regular market open, and a large indication of interest is no guarantee of a large — or any — allocation.
Step 4: Place Your Order Once Shares Are Allocated
This is where how to invest in IPOs using trading apps turns into an actual purchase. If you receive an allocation, the app converts it into an actual purchase at the finalized offering price; you generally don't set your own limit price for allocated shares, since the price was already fixed through the bookbuilding process. Some platforms give allocated investors a short confirmation window before market open. If you receive no allocation, or want additional shares beyond what was allocated, the only remaining path is buying on the open market once trading begins.
Step 5: Buying Shares After the Stock Lists
For investors who weren't allocated shares — the more common outcome for retail participants — the app functions like any other trade: you place a market or limit order once the stock begins trading publicly. Because first-day and first-week prices can swing well above or below the offering price, a limit order gives more control than a market order during this period (SEC Investor.gov, Investor Bulletin: Investing in an IPO). This is also the point at which the process converges with a standard online IPO purchase, which is covered in more general terms in our step-by-step guide to investing in IPOs online.
| Step | What Happens | Investor Consideration |
|---|---|---|
| 1. Eligibility check | App verifies restricted-person status and, often, a minimum balance or activity threshold | Confirm requirements in advance; eligibility does not guarantee an offering will be opened to you |
| 2. Indication of interest | You submit a nonbinding request for a maximum share amount at the expected price range | Can be adjusted or canceled before allocation; not a binding commitment |
| 3. Allocation | Underwriters and the brokerage decide who receives shares and how many, often via pro-rata or lottery methods | Retail allocations are frequently small, partial, or zero, even after confirming interest |
| 4. Order execution (allocated) | Allocated shares are purchased automatically at the final offering price | No price control at this stage; the offering price is already fixed |
| 5. Post-listing purchase | Shares are bought on the open market like any other stock once trading begins | Early price swings can be sharp; limit orders help manage execution price |
Typical Fees and Costs When Investing in IPOs Through Trading Apps
Fees are a smaller part of how to invest in IPOs using trading apps than allocation uncertainty, but they still matter. Most major trading apps that offer IPO participation do not charge a separate commission for the allocated IPO purchase itself, consistent with the broader shift to commission-free trading on U.S. equities. However, "commission-free" is not the same as cost-free. Investors should still account for the bid-ask spread on any post-listing purchase, potential regulatory transaction fees passed through on trades, and — for shares bought after listing rather than through allocation — the possibility of paying well above the offering price if the stock opens with a sharp first-day gain. Fee structures and IPO-access eligibility tiers vary by broker and can change, so confirm current terms directly in your app before assuming a given offering is commission-free.

Post-Listing Considerations: Lockups and Volatility
Even after you've placed an order, how to invest in IPOs using trading apps responsibly means understanding what happens in the months that follow. Company insiders, employees, and pre-IPO investors are typically subject to a lockup period — commonly around 180 days, though terms vary by company and some deals use staggered schedules that release different shareholder groups at different dates. As the lockup expiration approaches, the impending release of a much larger supply of shares can weigh on sentiment, and the expiration date itself has historically coincided with elevated volatility and price pressure in a number of past listings, since insiders become free to sell simultaneously. Newly listed stocks can also be more volatile generally in their first weeks and months of trading, before a longer public trading history and multiple quarterly earnings reports are available. Because pricing, valuation, and trading history are still forming immediately after an IPO, our guide on investing in IPOs for long-term growth covers how to evaluate a newly public company beyond the first-day trade.
Key Risks to Weigh Before You Use a Trading App for IPOs
Weighing the risks is the last piece of how to invest in IPOs using trading apps responsibly. Investing in an IPO is inherently speculative: the offering price is set through negotiation between the company and underwriters and may bear little relationship to where the stock trades once the public market opens (SEC Investor.gov, Investor Bulletin: Investing in an IPO). Because a newly public company has a short trading history, less publicly available financial disclosure than an established issuer, and no long-term price pattern to evaluate, valuation and liquidity risk are both elevated relative to seasoned stocks. There is also allocation risk — the shares you were hoping to buy at the offering price may simply not be available to you — and execution risk if you instead buy on the open market during a volatile first trading session. None of this is a reason to avoid IPO investing outright, but it is a reason to size any position conservatively and to treat a confirmed indication of interest as a possibility, not a guarantee. A broader framework for managing these risks is covered in our guide on how to invest in U.S. IPOs safely, and investors researching specific upcoming candidates before submitting interest can start with our roundup of anticipated IPOs and companies to watch.
Frequently Asked Questions
Does every trading app offer IPO access?
No — a key caveat for anyone learning how to invest in IPOs using trading apps. IPO participation is offered by a subset of brokerages and is not available for every offering, since underwriters and issuers decide which firms receive an allocation to distribute to retail customers.
Do I need a minimum account balance to invest in IPOs using trading apps?
It depends on the broker. Some firms set explicit asset or activity minimums before IPO participation is unlocked, while others advertise broader access with lower stated thresholds; check your specific app's current eligibility terms.
If I submit an indication of interest, am I guaranteed shares?
No. An indication of interest is a nonbinding request. Allocation is decided by the underwriters and your brokerage, and retail investors frequently receive a partial allocation or none at all.
Is it safer to wait and buy after the stock starts trading?
It removes allocation uncertainty, but it introduces price and execution risk instead, since shares purchased after listing trade at whatever the open market price is, which can be well above or below the offering price.
Conclusion
Knowing how to invest in IPOs using trading apps means understanding a process with several distinct gates: eligibility certification, a nonbinding indication of interest, an allocation decision largely outside your control, and only then an actual order — whether at the fixed offering price for allocated shares or at the prevailing market price after listing. Fees are typically limited to standard trading costs rather than a dedicated IPO commission, but allocation scarcity, valuation uncertainty, and post-listing volatility around lockup expiration remain real considerations. Treat any IPO purchase as a smaller, higher-risk position within a diversified plan, and confirm your broker's current eligibility rules and fee terms before submitting interest in any offering.
