How Does an IPO Work? A Simple Step-by-Step Guide for Beginners

The Initial Public Offering (IPO) is one of the most significant financial events that a company can experience in its existence. It’s when the company that is privately owned decides to offer its shares publicly for the first time, and transform into a publicly traded corporation. There’s no doubt that you’ve heard of major IPOs such as Facebook, Airbnb, or Uber, but what exactly does it take to operate?

If you’ve ever wondered:

Why do companies go public?
Who decides on the IPO pricing?
What will happen on the day that trading begins?
Why do certain IPOs do well and some fail?

This guide explains everything in simple, understandable terms–no need for a finance degree.

IPO Meaning: What Is an Initial Public Offering?

An Initial Public Offering (Initial Public Offering) is when a private company offers it shares market for the first time. This allows everyone (not only the wealthiest shareholders) to purchase a share of the business.

Why Companies Go Public: IPO Benefits and Drawbacks

It’s not just about getting noticed, it’s also a financially strategic move. Businesses pursue IPOs for three main reasons:

Raise Money to Grow: Selling shares can bring the company millions (or billions), which can be used for expansion or research. It can also fund acquisitions, acquisitions, or expansion.
- Example: Airbnb raised $3.5 billion through its IPO to help recover from losses due to the pandemic.
Early Investors and employees cash out: Venture capitalists, founders, and employees frequently sell shares to secure the profits.
- Example: Facebook’s early investors were billionaires in a matter of hours.
Improve Brand Trust and visibility. Being traded publicly increases credibility and draws new customers as well as partners.

However, going public isn’t all sunshine and rainbows: it is accompanied by more costs, tighter regulations as well as shareholder pressure. Some companies (like SpaceX and Stripe) hold off on public offerings for years to prevent these negatives.

Step 1: Hiring Investment Banks (Underwriters)

Before all else, the business requires the investment bank (like Goldman Sachs or Morgan Stanley) to guide the IPO. These banks function in the role of “underwriters”-they help to determine price for IPO price, identify buyers, and deal with the legal documentation.

Underwriters earn money through charging fees (4-7% of the IPO sum).
Example: When Snowflake went public in the year 2020, the company paid more than $200 million in charges towards its underwriters.

Step 2: SEC Filings & Financial Disclosures

The company has to file an S-1 Registration Form to the SEC (Securities and Exchange Commission), which includes:

Financial statements (profits, losses, debts)
Risks to business (competitors and lawsuits)
How will the IPO cash be utilized

The document is accessible to the public–anyone can access it before deciding to invest.

Interesting Facts: Facebook’s S-1 Filing was more than 200 pages!

Step 3: The Roadshow (Selling the IPO to Big Investors)

Prior to the IPO begins the CEO and bankers embark on a “roadshow,” a series of meetings with hedge funds, mutual funds, as well as large investors to persuade them to purchase shares.

They discuss how the business is a great investment.
Investors make orders based on the interest rate.
Example: Uber’s roadshow was a struggle due to investors’ doubts about its viability, resulting in a lower price for its IPO.

Step 4: Setting the IPO Price

The underwriters study demand from investors and then decide:

What is the number of shares I should sell?
At what cost
If the demand is high If demand is high, the price rises.
If the interest rate is low, the price will fall.
Example: Airbnb priced its initial public offering at $68 per share. However, on the day of its first trading, the demand exploded and shares rose 112 percent!

Step 5: IPO Launch & First Day of Trading

The day of the IPO:

The stock is traded through the exchange ( NYSE or Nasdaq).
The price could rise (if the demand is high) or even crash (if investors cease to be interested).

Biggest First-Day IPO Pops:

Snowflake (2020): +111%
LinkedIn (2011): +109%
Facebook (2012): Flat (controversial debut)

Step 6: The Lockup Period (When Insiders Can’t Sell)

Following the IPO, early investors and employees cannot sell their shares for 90 to 180 weeks (the “lockup period”).

After this time, a flood of shares may come into the market at times, crashing the value of the stock.
Example: Beyond Meat’s stock fell by 30% or more after the lockup expires.

IPO Risks vs. Rewards: Why Some Companies Succeed and Others Fail

IPO is not easy, and not easy things tend to bite back. IPOs require quite a large backlog of money from investors. Not only that, investors are supposed to keep the IPO in place even if the IPO gets shaky (it’s always shaky). Hence, IPO comes with an RR ratio. RR means Risk to reward ratio or vice versa.

Some tools or some extra thinking, deep talks, and insider information help decide the RR ratio. Also, it’s the plan that holds.

Here are some IPO Risks Vs. Rewards analysis by telling you about some successful ones and some not successfull ones.

Successful IPOs

A Business Plan that is Strong (Profitable and high growth)
Great timing (Launching on a crowded market)
smart pricing (Not too extravagant)

Examples: NVIDIA’s IPO (1999) – Priced at $12. Now worth $ 700 plus per share after splits of the stock.

Failed IPOs

Poor financials (Losing money without an obvious path to profits)
Value Overhyped (Priced way too high, and then it crashes)
Poor Economic Conditions (Economic downturns affect IPOs)

Example: WeWork (2019) – Valued at $47 billion privately, but the company canceled its initial public offering following investors’ concerns over the company’s losses.

Successful vs. Failed IPOs (Comparison Table)

Company	IPO Year	IPO Price	Current Status	Key Lesson
Snowflake	2020	$120	+400% (2025)	Strong cloud demand, priced well.
Beyond Meat	2019	$25	-90% (2025)	Overhyped, no profits.
Airbnb	2020	$68	2x returns	Pandemic recovery play.
WeWork	Cancelled	–	Bankruptcy	Burned cash, weak model.

IPO Trends in 2025: What’s Changing?

More tech IPOs – Companies such as Stripe, Reddit, and SpaceX might be able to go public.

Final Thoughts: Should You Invest in an IPO?

IPOs are thrilling, but they can also be they can also be risky. While certain companies (like Google and Amazon) have made investors who were early wealthy, other companies (like Blue Apron and WeWork) were wiped out following the IPO.

Before you invest in an IPO, consider:

Does the business have a straight path to profitability?
Is the appraisal acceptable?
Are conditions in the market favorable?

If you’re uncertain you’re not sure, it’s best to put off several months following the IPO to observe how the stock does.
