How Small Investors Can Buy IPO Shares: Lessons From the SpaceX Listing

Quick answer: Small investors can buy shares in an initial public offering (IPO) in two ways: by applying for an allocation at the IPO price through a broker before the shares start trading, or by buying on the stock market once trading begins. The SpaceX listing on 12 June 2026, the largest IPO in history at about $75 billion, showed the difference. Investors who were allocated shares at the $135 offer price were up 19% at the first day's close of $160.95; those who bought at the opening trade of $150 were up only about 7%; and anyone who bought near the day's high of $176.52 was down about 9%. In the US, apps such as Robinhood, Fidelity, Schwab, SoFi and E*Trade offer retail allocations, but popular deals are heavily oversubscribed and most applicants get few or no shares. In India, retail investors apply through their bank or broker using ASBA or UPI, with allocations decided by lottery when demand is high. Research over decades shows that IPOs often rise on day one but tend to lag the wider market over the following years, so treat them as a small, speculative part of a portfolio.

Few events in the stock market attract as much excitement as a big IPO. A company that has grown for years on private money, often famous long before anyone could buy a piece of it, finally sells shares to the public. Headlines count the instant paper fortunes of founders and early employees. Ordinary investors wonder whether they can get in on the ground floor.

2026 has been an extraordinary year for listings. SpaceX's offering raised more money than all US IPOs of the previous two years put together, and the second quarter set a record for IPO proceeds. This guide explains how IPOs work, how ordinary investors in the US, India and elsewhere can take part, what the evidence says about IPO returns, and the lessons the SpaceX listing offers anyone tempted by the next big debut.

What an IPO Is

An initial public offering is the first time a private company sells shares to the public and lists them on a stock exchange. It does so to raise money for growth, to let early investors and employees sell some of their holdings, or both.

The process follows a well-worn path. The company hires investment banks as underwriters, files a detailed prospectus with regulators, the Securities and Exchange Commission in the US or the Securities and Exchange Board of India (SEBI) in India, and goes on a "roadshow" to pitch large investors. The banks gauge demand and, with the company, set the offer price, usually the night before trading begins. Shares are allocated to investors at that price, and the next morning they start trading on the exchange, where the price is set by buyers and sellers.

The gap between the offer price and the first trades is what makes IPOs so exciting, and so uneven in who benefits.

The SpaceX IPO: What Happened

  • Price: SpaceX priced its shares at $135 on 11 June 2026, after a roadshow from 3 to 11 June.
  • Size: it sold more than 555 million shares, raising about $75 billion, the largest IPO ever, ahead of Saudi Aramco's $29.4 billion listing in 2019.
  • Retail access: the company reportedly reserved around 30% of the offering for individual investors, far more than is usual for a large IPO, distributed through brokers including Robinhood, Fidelity, Charles Schwab, SoFi and E*Trade. Some brokers set minimum account sizes or required accounts to be funded days in advance.
  • First day: the shares opened on the Nasdaq at $150 under the ticker SPCX, rose as high as $176.52 and closed at $160.95, up 19%. At the close, the company was valued at about $2.1 trillion.
  • What comes next: insiders and early investors are typically barred from selling for 180 days after an IPO. For SpaceX, that "lockup" expires in December 2026, an event that can weigh on the share price as more shares become available to sell.

The SpaceX deal pulled the whole market along. US IPOs raised a record $104.8 billion in the second quarter of 2026 across 48 listings, according to Renaissance Capital. The pace slowed sharply in the third quarter, when rising bond yields, renewed interest-rate rises and doubts about spending on artificial intelligence made investors more cautious; excluding one large listing, by the South Korean chipmaker SK hynix, third-quarter proceeds were only about $6 billion.

How Small Investors Can Get IPO Shares in the US

For most of the history of the US stock market, IPO allocations went almost entirely to large institutions and wealthy clients of the underwriting banks. That has changed in recent years. Today there are several routes:

  1. Retail IPO programmes at brokers. Robinhood, SoFi, Fidelity, Charles Schwab, E*Trade and others let customers request shares in some IPOs at the offer price. You indicate how many shares you want before pricing, and confirm once the price is set. Allocations are not guaranteed, and for popular deals most customers receive only part of their request, or nothing.
  2. Eligibility rules. Some brokers restrict IPO access to customers with a minimum account balance or trading history, and some regulators' rules limit how quickly you can sell after receiving shares without losing future access.
  3. Buying on the first day. Anyone with a brokerage account can buy once the shares begin trading. You pay the market price, which may be well above the offer price.
  4. Waiting. You can buy at any time after the IPO, once the excitement has settled, the first earnings reports are out and the lockup has expired.
  5. Funds. Some exchange-traded funds specialise in recent IPOs, and once a large company joins indices such as the Nasdaq-100 or S&P 500, index funds will buy it automatically.

How IPOs Work in India

India has one of the most active IPO markets in the world, with millions of individual investors applying for popular issues. The rules are designed to give retail investors a fair share:

  • Reserved portion: in most main-board IPOs, 35% of the shares on offer are reserved for retail individual investors applying for up to ₹2 lakh.
  • How to apply: through your bank's net banking using ASBA (Application Supported by Blocked Amount), or through a broker's app using a UPI mandate. The money stays in your account but is blocked until allocation.
  • Lots: you apply in multiples of a fixed minimum lot size.
  • Lottery allocation: if the retail portion is oversubscribed, allocation is by computerised lottery, with each successful applicant usually receiving one minimum lot. In heavily oversubscribed issues, most applicants receive nothing, and blocked money is released.
  • Grey market premium: unofficial "grey market" prices are widely quoted before listing, but they are unregulated, can be manipulated and are a poor guide to the listing price.
  • SME IPOs: smaller companies list on separate SME platforms with larger lot sizes and lighter disclosure. SEBI has warned investors about the risks and tightened rules after signs of excessive speculation.

Listing gains on Indian IPOs have often been large, which has drawn huge numbers of applicants. But many companies that listed with fanfare have since traded below their issue prices, and SEBI has repeatedly urged investors to study the prospectus rather than chase listing day gains.

IPOs Elsewhere

  • United Kingdom: retail investors have historically had little access to IPO allocations, but platforms that pass on allocations from large offerings have grown, and the London Stock Exchange has reformed its listing rules to attract more companies.
  • Europe and Asia: access varies by country. Hong Kong IPOs often include a public tranche with a lottery when demand is high; in mainland China, retail investors apply through exchanges with allocation by lottery.
  • Cross-border buying: investors outside the US can usually buy US-listed shares once trading begins through an international broker, but most US brokers' IPO programmes are open only to US residents.

Why IPOs Often Jump on Day One

IPOs are deliberately priced a little below what the underwriters think the market will pay. That "underpricing" rewards the investors who commit early, reduces the risk of a disappointing debut and helps the banks' reputation. Research by Jay Ritter of the University of Florida, who has tracked US IPOs since the 1980s, finds an average first-day gain of close to 20%, with much bigger jumps during hot markets such as the dot-com boom.

That first-day gain goes mainly to whoever received shares at the offer price. Everyone else buys at the market price after the jump.

What Happens After the First Day

The longer-term record is much less exciting. Ritter's data, and many other studies, show that US IPOs have, on average, lagged the wider stock market over the three to five years after listing. There are many explanations: companies tend to go public when investors are most enthusiastic about their sector, insiders sell when they think the price is high, and early optimism about growth often fades.

There are spectacular exceptions. Amazon, Google and Nvidia all listed at prices that look absurdly cheap today. But there are many more companies that disappointed: in the US, dozens of the most hyped listings of 2020 and 2021 fell by 50% or more within two years. The few great winners are hard to identify in advance, and the average IPO is not a bargain.

What is an IPO application really worth?

Popular IPOs are heavily oversubscribed, so you rarely get all the shares you ask for. Test how much you are likely to be allocated and what it could be worth.

Shares you actually get, by value—
Gain if you sell on the first day—
Value after a year if you hold—
Gain on your whole application—

In India, when a public issue's retail portion is oversubscribed, shares are usually allocated by lottery, one lot per winning applicant, so many applicants get nothing. In the US, brokers allocate retail shares by their own rules. Money for unallocated shares is returned or released.

Famous IPOs, and What Happened Next

  • Netscape, 1995: priced at $28, the web browser company's shares opened at $71 on their first day, a moment often seen as the start of the dot-com boom. Netscape was overtaken by Microsoft's Internet Explorer within a few years and sold to AOL in 1999.
  • Google, 2004: the search company used an unusual online auction to set its price at $85 and give individual investors more access. Investors who held on have made many times their money.
  • Facebook, 2012: priced at $38 in one of the most anticipated listings of its era, the shares barely rose on day one amid technical problems at the Nasdaq and fell to below $20 within four months. Patient holders were eventually rewarded handsomely.
  • Alibaba, 2014: raised $25 billion in New York, then the largest IPO ever. Its shares later rose strongly, then fell far below their peak amid China's crackdown on technology firms.
  • Saudi Aramco, 2019: raised $29.4 billion, the record until SpaceX, mostly from Saudi and Gulf investors.
  • The 2020 and 2021 boom: hundreds of companies listed through traditional IPOs and blank-cheque companies, many of which later fell by more than half.

The pattern is consistent: the first day tells you about excitement, not about the next ten years.

Direct Listings, SPACs and Other Routes to Market

A traditional IPO is not the only way a company can go public.

  • Direct listings: the company lists existing shares on an exchange without selling new ones or setting an offer price through underwriters. The first price is set by buyers and sellers on the day. Spotify and Coinbase used this route. There is no IPO allocation to apply for; everyone buys at the market price.
  • SPACs: special purpose acquisition companies, or "blank-cheque" companies, list on an exchange with cash and then merge with a private company, taking it public. They boomed in 2020 and 2021; many of the companies they brought to market performed poorly, and regulators have since tightened the rules.
  • Offer for sale and follow-on offers: in India and elsewhere, existing owners, including governments, often sell shares in listed companies through public offers with retail portions, which can offer similar access at a discount.

Lessons From the SpaceX Listing

  1. Allocation is where the easy money is. The 19% first-day gain belonged to people who got shares at $135. Buyers on the open market paid much more, and those who chased the price at the peak were quickly sitting on losses.
  2. You will probably get less than you ask for. Even with a large retail allocation, demand for SpaceX shares far exceeded supply. Plan around a partial allocation.
  3. Size matters more than the headline. A spectacular first-day gain on a small allocation barely moves a portfolio. The calculator above shows why.
  4. Valuation still counts. At around $2.1 trillion after its first day, SpaceX was valued like one of the largest companies in the world. Future returns depend on whether it can grow into that valuation, not on how exciting its rockets are.
  5. Watch the lockup. When insiders become free to sell, share prices often come under pressure.
  6. Index funds will own it anyway. Once SpaceX joins major indices, investors in broad index funds will hold a small slice automatically, without having to bet on it.

How to Evaluate an IPO

If you are considering an IPO, treat it like any other investment, with extra caution because there is no trading history:

  • Read the prospectus, at least the summary, risk factors, financial statements and use of proceeds. Who is selling shares, the company or existing owners?
  • Check the profits, not just the growth. Is the company profitable? If not, how long can it fund losses?
  • Compare the valuation with similar listed companies, using price-to-earnings or price-to-sales ratios.
  • Look at the share structure. Many technology companies list with dual-class shares that leave founders in control, limiting the say of ordinary shareholders.
  • Note the lockup date and the share of the company being floated. A small float can make the share price very volatile.
  • Ask why now. Companies, and their private backers, choose the moment when they think they can get the best price. That is rarely the moment that is best for buyers.

Finally, decide in advance what you will do on listing day: sell, hold or add, and at what prices. Making that plan while you are calm is far easier than making it while the share price is jumping around on your screen.

Common IPO Mistakes

  • Buying at the opening bell out of excitement. The first minutes of trading are often the most volatile.
  • Applying with borrowed money or money you need, hoping for a quick listing gain.
  • Relying on grey market premiums or social media tips.
  • Putting too much into one listing. Even great companies can be poor investments at the wrong price.
  • Ignoring tax. Selling on listing day usually counts as a short-term gain, taxed at a higher rate in many countries, including the US and India.

Frequently Asked Questions

Can ordinary investors buy shares at the IPO price?

Yes, increasingly. In the US, brokers such as Robinhood, SoFi, Fidelity, Schwab and E*Trade offer retail IPO allocations; in India, retail investors apply through ASBA or UPI and 35% of most main-board issues is reserved for them. Popular deals are oversubscribed, so allocations are often small or by lottery.

How did the SpaceX IPO perform?

SpaceX priced at $135 a share on 11 June 2026, raising about $75 billion, the largest IPO ever. The shares opened at $150 on 12 June, reached $176.52 and closed at $160.95, up 19% from the offer price.

Are IPOs good investments?

On average, they have tended to rise on the first day and then lag the broader market over the following years, according to long-run research. Some become huge winners, but they are hard to pick in advance. Most investors are better served by broad index funds, with IPOs as a small speculative extra if at all.

What is an IPO lockup period?

A period, usually 180 days, during which company insiders and early investors agree not to sell their shares. When it ends, a large number of shares can come onto the market, which sometimes pushes the price down.

What is oversubscription?

When investors apply for more shares than are on offer. An issue subscribed 50 times over in its retail portion means applications for fifty times the shares available, so most applicants receive little or nothing.

Does applying for more shares improve my chances?

In India, generally no: when the retail portion is oversubscribed, each applicant is entered once into the lottery for a minimum lot, so applying for the maximum mainly blocks more money. Applying through different family members' own accounts is allowed, but multiple applications under the same PAN are rejected. In the US, broker rules vary; some favour customers with larger or longer-standing accounts.

Can I buy a company's shares before its IPO?

Usually only through private funding rounds open to wealthy, accredited investors, or through specialised funds and platforms that trade private company shares. These carry high fees, little information and limited ability to sell. Some crypto exchanges offer "pre-IPO" contracts that track expected prices; they are speculative derivatives, not shares.

Should I sell IPO shares on listing day?

It depends on why you applied. If you only wanted a listing gain, selling locks it in, though it may be taxed as a short-term gain. If you believe in the company long term, holding can make sense, but judge it as you would any other share: on its profits and valuation, not the excitement of the debut.

Final Thoughts

The SpaceX listing was a landmark: the largest IPO in history, and one of the first in which ordinary investors were invited to take a meaningful share from the start. For the lucky ones who received an allocation, it paid off on day one. For many who bought in the excitement of the first trades, it was a reminder that the market price of a new listing can run far ahead of any reasonable estimate of value.

The healthiest way to approach IPOs is with curiosity and restraint. Apply if you want to, with an amount you would be comfortable losing; read the prospectus; and do not let the drama of listing day pull you into decisions you would not make about any other share. Over the long run, the patient investor who owns the whole market, including the IPOs that succeed, usually does better than the one chasing each new debut.
