How to Make Money on IPOs: Allocations, Brokers, and What Actually Works for Retail Investors

This article is for educational purposes only and does not constitute investment advice. IPO investing carries significant risk including potential loss of principal.

The SpaceX IPO has a lot of people suddenly interested in how IPO investing actually works. The short answer: most retail investors have been doing it wrong — or not doing it at all — because nobody explained the mechanics clearly. This is that explanation.

How IPOs Actually Work: The Mechanics

A company going public hires investment banks (underwriters) to manage the offering. The underwriters price the IPO, market it to institutional investors during a roadshow, and allocate shares. Historically, 90–95% of shares go to institutional buyers — pension funds, mutual funds, hedge funds — who have long-standing relationships with the underwriters and commit to large block purchases.

Retail investors — individual people with brokerage accounts — have traditionally been given scraps. A small percentage of some IPOs flowed to retail via the underwriting bank’s brokerage arm, but access was inconsistent and often required a relationship manager or a minimum account balance.

That is changing. Direct listing platforms, fintech brokers, and deliberate policy decisions (like SpaceX’s 30% retail allocation) are opening IPO access to ordinary investors. But the mechanics still matter — and misunderstanding them costs money.

Which Brokers Offer IPO Access to Retail Investors

Broker	IPO Access	Minimum Account	Key Rules
Fidelity	Yes — broad access	No minimum stated, but active account required	Must hold shares for 15 calendar days or lose future IPO access for 12 months
Charles Schwab	Yes	No stated minimum for participation	Must hold shares for 15 calendar days; violations restrict future access
TD Ameritrade (now Schwab)	Merged into Schwab	—	Same as Schwab rules
Interactive Brokers	Yes — one of the broadest retail IPO programs	No minimum, but account must be funded	30-day flip restriction on most IPOs; serious enforcement
Robinhood	Yes — IPO Access program	No minimum	Must hold for at least 30 days; selling early blocks you from future IPOs for 60 days
E*TRADE (Morgan Stanley)	Yes — Morgan Stanley relationship helps allocation access	$100,000+ account for best access	Flip restriction applies; Morgan Stanley clients get priority
Merrill Edge (Bank of America)	Yes — for Preferred Rewards members	Better access at $20k–$100k+ tiers	Preferred Rewards Gold and above get priority allocation
SoFi	Yes — member IPO access	SoFi account required	Must hold shares for 30 days

Brokers that do NOT offer retail IPO access: Vanguard, most robo-advisors ([Betterment](https://www.betterment.com/?ref=aedilis), Wealthfront), and most credit union investment accounts. If you only invest through Vanguard, you are locked out of IPO participation at the offering price.

How Allocations Actually Work

Understanding the allocation process is the most important part of this guide. Here’s the real process:

1. Indication of Interest (IOI): Once your broker announces an IPO, you submit how many shares you want and at what price range you’d accept. This is not a binding order — it’s expressing interest.
2. Book building: The underwriters aggregate all IOIs from institutions and retail. They use this to gauge demand and set the final offering price.
3. Allocation: Shares are distributed. Institutional orders typically get the lion’s share. Retail is proportionally allocated — if 100,000 retail shares are available and $5 million in retail demand exists for a $25 stock, demand (200,000 shares) is 2× supply, and allocations come back at 50 cents on the dollar of what you requested.
4. Confirmation: You’re notified of your allocation (often partial) and the final price. You have a final window to confirm or cancel your participation at the confirmed price.
5. Settlement: Shares settle in your account. The flip restriction clock starts from settlement date.

The oversubscription reality: High-profile IPOs (like SpaceX) will be massively oversubscribed. If you request $5,000 in shares and demand is 20× supply, you’ll receive ~$250 in shares. This is normal. Request a larger position than you want, knowing you’ll receive a fraction.

What the Research Actually Says About IPO Returns

Before you get too excited about IPO access, here’s what the data shows:

Short-Term: The “IPO Pop” Is Real — But It’s Not Yours by Default

Studies consistently show that IPOs pop an average of 15–20% on the first day of trading. The problem: that pop accrues to people who got shares at the offering price, not people who buy on the open market at day one. If you get allocated shares at $25 and they open at $30, you made 20% before 9:35 AM. If you buy at $30 because you didn’t get an allocation, you’ve already missed the pop.

This is why getting the allocation — not just buying the stock — is the whole game in short-term IPO trading.

Long-Term: The Research Is More Sobering

Academic research consistently shows that IPOs underperform comparable public companies over 3–5 years after listing:

• Jay Ritter’s landmark IPO research (University of Florida) shows average 3-year underperformance of ~20% relative to matched public companies
• The “IPO lockup expiration effect” — when insider lockups expire at 90 or 180 days, insiders can sell, which often creates a second wave of selling pressure
• First-year volatility is dramatically higher than mature public companies

The exceptions that performed: Not all IPOs underperform long-term. The ones that historically created the most wealth for post-IPO public investors share a few traits:

• Profitable (or clearly on the path to profitability) at IPO
• Large addressable market with genuine competitive moat
• Reasonable valuation relative to revenue (not 50–100× revenue at listing)
• Founders still running the company and retaining significant equity

Companies that went public meeting these criteria — Apple (1980), Amazon (1997), Google (2004), Visa (2008) — all created generational wealth for patient investors. The dot-com era IPOs that failed — Pets.com, Webvan, countless others — failed primarily because they lacked profitability, realistic economics, or both.

IPO Vintage Analysis: What Years Produced Returns

IPO Cohort	Average 3-Year Return vs. S&P 500	Notes
1999–2000 (Dot-com)	−55%	Massive overvaluation; most companies failed
2004–2007 (Pre-GFC)	−12%	Decent fundamentals; financial crisis disrupted
2012–2019 (Tech boom)	+8%	Strong fundamentals; long bull market helped
2020–2021 (SPAC/ZIRP boom)	−40%+	Speculation-driven; rising rates crushed valuations
2023–2025 (Recovery)	+5%	Selective; profitable companies outperformed

The pattern is clear: IPOs launched during periods of excessive speculation underperform dramatically. IPOs of genuinely profitable, well-run businesses in normal market conditions tend to perform reasonably.

The Flip Restriction Rules: Broker-by-Broker

This is where most retail IPO investors make expensive mistakes. Every broker that offers IPO access has rules about how long you must hold shares. Violating these rules doesn’t just cost you money — it can lock you out of IPO access for 12–24 months at that broker.

Broker	Flip Restriction Period	Penalty for Early Sale
Fidelity	15 calendar days from IPO date	Barred from IPO participation for 12 months
Charles Schwab	15 calendar days from IPO date	Barred from IPO participation for 12 months
Interactive Brokers	30 days from first day of trading	Restricted from future IPO participation
Robinhood	30 days from IPO date	Barred from IPO access for 60 days
E*TRADE	15–30 days (varies by offering)	Potential account restriction
SoFi	30 days	Suspended from future IPO access

Practical implication: If you participate in the SpaceX IPO in June, plan to hold the shares through at least mid-July. Have cash available for that full holding period. Do not allocate money you might need before the flip window closes.

The Strategy That Actually Works: A Framework

After studying IPO performance data and participating in several myself, here’s my framework:

Participate when:

• The company is profitable or has a clear, near-term path to profitability
• The offering price represents a reasonable valuation (under 20× revenue for high-growth; under 10× for established businesses)
• You can genuinely hold for 30+ days without needing the capital
• The IPO is at a broker with broad retail participation (not a platform that allocates only to premium customers)
• Your allocation size is 2–5% of your investable portfolio maximum

Skip when:

• The company has no clear profitability path
• The valuation is extreme relative to revenue or comparable companies
• The IPO is dominating financial media (peak hype is a warning sign, not a buy signal)
• You’re being asked to pay a premium for “priority access” or special IPO platforms
• The bulk of your portfolio would be needed to get a meaningful allocation

Platforms for Pre-IPO Access (Accredited Investors Only)

If you’re an accredited investor, pre-IPO shares are accessible through:

• EquityZen — minimum investments from $10,000; wide selection of pre-IPO companies
• Forge Global — largest secondary market; institutional-grade but retail accessible
• Hiive — newer, competitive pricing; growing inventory
• Linqto — lower minimums than most ($2,500 in some cases); fintech-focused

Pre-IPO shares are illiquid (you may not be able to sell until an IPO or acquisition), difficult to value, and carry company-specific risk. They’re appropriate for a small allocation of a sophisticated portfolio, not a core strategy.

The Bottom Line

IPO investing is not a guaranteed path to quick profits. The average IPO underperforms the index over 3–5 years. The IPO pop accrues to allocation holders, not open-market buyers. And most retail investors have historically been excluded from the allocation entirely.

What’s changing: platforms like Fidelity, Schwab, Interactive Brokers, and Robinhood are opening access. SpaceX’s 30% retail allocation is a signal that high-profile issuers may deliberately choose to share the opening-price opportunity with retail investors.

The opportunity is real. But the framework still matters: profitable companies, reasonable valuations, appropriate position sizing, and respect for the holding period rules. That’s the discipline that separates the investors who build wealth from IPOs from the ones who just get excited and lose money buying after the pop.
