What is an IPO? The Simplest Guide for Beginners in 2026

By Antonios Fotakis | June 2026

A note before you read: This is not a complicated finance article. No jargon. No hype. Just an honest explanation of what an IPO really is – and what most financial media won’t tell you about it.

What is an IPO. Let me ask you something.
Have you ever watched a friend turn their small business into something serious – and wished you could have bought in early, before it got big?
That moment – when a private company opens its doors to public investors for the very first time – is called an IPO.
Except instead of your friend’s business, it’s a company that’s been growing for years, backed by private investors who are now ready to let the rest of the world in. And instead of a handshake, there’s a listing on the stock exchange. And instead of a favour, there’s a price – set by banks, shaped by demand, and not always in your favour.

That’s it. Now you know what is an IPO. Let’s go deeper.

You Can Buy Into a Company the Day It Goes Public. But Should You?

Understanding what is an IPO is one of the most useful things an investor can do – because IPOs generate more excitement than almost any other financial event. And excitement, in investing, is usually a warning sign.
When a private company decides it wants to raise money from the public, it lists its shares on a stock exchange. From that day forward, anyone with a brokerage account can become a part-owner.

The company issues a formal prospectus – a document that explains what the business does, how it makes money, what the risks are, and how many shares are being offered at what price.
That price is called the IPO price. And it is set by the company, its founders, and the investment banks they hire to manage the process. Not by the market. Not by you.

So What is an IPO and What Does Buying In Actually Mean?

When you buy shares in an IPO, you are becoming a part-owner of the company – just like buying any other stock.
But there is a crucial difference from buying an established company.
With a listed company that has been public for years, you have years of financial data, earnings reports, analyst coverage, and market history to study. With an IPO, you have a prospectus and a pitch.
This is the fundamental asymmetry:
– The company and its bankers know everything about the business.
– You know what they’ve chosen to tell you.
That information gap is not a reason to never invest in IPOs. It is a reason to be deliberate, patient, and sceptical of the hype.

How Does an IPO Actually Work?

Now that you understand what is an IPO, let’s look at the process behind it.

Step 1: The company hires an investment bank – called the underwriter. Banks like Goldman Sachs or Morgan Stanley evaluate the business, set an initial price range, and spend weeks presenting it to large institutional investors. This roadshow is where the real price discovery happens.

Step 2: The IPO price is set. Based on demand from institutional investors, a final listing price is agreed – say, $20 per share.

Step 3: Shares go live on the exchange. On the IPO date, shares begin trading publicly. The opening price on the market may differ – sometimes dramatically – from the listing price. That first-day surge is what the financial press calls the “IPO pop.”

Step 4: Anyone can now buy the stock. Including you, through your regular brokerage account. Usually after the institutions have already positioned themselves.

Who Actually Gets the Best Deal?

Here is the part that most IPO coverage skips – and it matters enormously.

IPOs are almost always priced in favour of the seller, not the buyer.
The company and its bankers have one goal: raise as much money as possible at as high a price as possible. Institutional investors – hedge funds, pension funds, large asset managers – get first access to shares at the listing price, often before trading even begins.
By the time a stock is available to you through a regular brokerage, the price may have already spiked.
The “IPO pop” you read about in headlines? That largely benefits the institutions who bought in at the original price. Retail investors who buy on day one often buy at the top of the first-day excitement.

Who Actually Gets the Best IPO Deals?

Not retail investors. That’s the uncomfortable reality.
Institutional investors – hedge funds, pension funds, asset managers – get first access to IPO shares at the listing price, often before trading even begins. By the time a stock is available to you and me through a regular brokerage, the price may have already spiked.

The Numbers Behind the Hype

Understanding what is an IPO means understanding the numbers behind the hype.
Some IPOs have delivered extraordinary returns. Many have not. Here is a snapshot of some well-known examples and how they performed one year after listing.

The lesson is not that IPOs are always bad. It’s that timing and patience matter more than excitement.

The Risks Nobody Talks About Honestly

When you understand what is an IPO, you also need to understand the risks that come with it.
IPOs are often described as opportunities. And sometimes they are. But they carry very specific risks that you deserve to understand clearly.

Overvaluation risk: The IPO price is set to maximise what the company raises – not to give you a bargain. Many IPOs are priced above what the business is actually worth, and reality corrects that over time.
Lock-up expiry risk: Insiders – founders, employees, early investors – are typically restricted from selling shares for 90 to 180 days after the IPO. When that window expires, a flood of selling can push the price sharply lower.
Limited track record: Without years of public financial data, you are making a judgment call on limited information. The prospectus tells you what the company wants you to know.

Here is what I believe, and what shapes every pick we make at AF Core Global:
Understanding the risk is not a reason to avoid an asset. It’s the reason you can use it intelligently.

So Why Consider IPOs at All?

Once you understand what is an IPO, the next question is simple: is there ever a good reason to buy in?

Yes – with patience.

Some of history’s greatest compounders started as IPOs. Amazon, Google, Netflix. If you had bought any of these and held them, the returns would have been extraordinary. But in each case, the real opportunity was not on day one. It was after the hype faded and the price found its real level.
Waiting 6 to 12 months after an IPO often gives you a far better entry point than buying into the excitement. By then, the lock-up period has passed, the institutional sellers have moved on, and the market has had time to price the company on fundamentals rather than narrative.
The key word is timed. Patience almost always beats excitement in this game.

Key IPO Terms You’ll Encounter

Underwriter: The investment bank that manages the IPO process.
Roadshow: Presentations to institutional investors before the IPO.
Lock-up Period: 90–180 days post-IPO during which insiders cannot sell shares.
IPO Price: The official price at which shares are first offered.
Opening Price: The first traded price on the market – often different from the IPO price.
Oversubscribed: When demand for IPO shares exceeds supply.
Direct Listing: A company goes public without raising new capital – no IPO price set.
SPAC: A shell company that merges with a private company to take it public.

What We Do at AF Core Global

Knowing what is an IPO is only half the picture – knowing when to act is the other half.
IPOs sit almost exclusively in our High Voltage category – high risk, high potential reward, and not suitable for every investor.
If you are building a Fortress portfolio of stable ETFs and bonds, an IPO has no place there. If you are a Cash Flow investor focused on dividends and REITs, newly public companies rarely pay dividends.
But if you have risk capital – money you can afford to see fluctuate – and you have done the research, a well-timed IPO entry can generate significant returns.

Every week, we share one High Voltage pick with full transparency on what we paid, what the thesis is, and how the position is performing.
We’re not financial advisors. We’re not telling you what to buy. We’re showing you what we’re watching, what we believe in, and why – so you can make your own informed decision.

Because that’s what this is all about.
Not blind trust. Informed choice.
