You've heard it on the news. "Such-and-such just had a massive IPO." Everyone nods like they know exactly what happened. And maybe you nodded too, while quietly thinking: what actually is an IPO, though? By the end of this blog you'll understand what an IPO is, why a company would bother, and the jargon you'll hear thrown around. No finance degree required. Let's get into it.
The short version
IPO stands for Initial Public Offering. It's the first time a company sells shares of itself to the general public — including everyday investors, big fund managers, and super funds by listing on a stock exchange like the ASX (the Australian Securities Exchange).
Before its IPO, a company is private. Its shares are owned by a small group: the founders, early staff, maybe some venture capital or private equity investors. You can't just buy in.
After its IPO, the company is public. Anyone with a brokerage account can buy and sell its shares. That's the whole idea of "going public" as it opens ownership up to the market.
Why would a company do this?
Mostly, it comes down to one word: money, but it's worth understanding the flavours.
To raise capital. This is the big one. Selling new shares to the public brings in cash the company can use to grow such as build a new factory, expand overseas, pay down debt, hire hundreds of people. Instead of borrowing the money (taking on debt), the company raises it by selling small slices of ownership (equity). If you want the fuller picture on that trade-off, we broke it down in debt vs equity — how companies raise money.
To let early investors and founders cash out. The people who backed the company years ago - think founders, staff with shares, VC funds - have been holding an investment they can't easily sell. An IPO gives them a way to turn some of those shares into actual money.
For profile and credibility. Being listed on a public exchange comes with scrutiny, but also prestige. It can make a company look more established to customers, partners and future hires.
So an IPO is really two things happening at once: a fundraising event, and a coming-out party.
How it actually works (the simple walkthrough)
Here's the journey, minus the 300-page prospectus.
1. The company decides it's ready. Going public is a big, expensive, scrutiny-heavy decision. The company needs solid financials and a growth story that will convince investors.
2. It hires investment banks. These banks are called underwriters. Their job is to help price the shares, drum up interest from big investors, and basically manage the whole launch. This is a huge chunk of what people in investment banking actually do day to day.
3. It publishes a prospectus. This is a formal document (in Australia, lodged with ASIC) that lays out the company's financials, risks and plans. It's the "here's everything you should know before you buy" document.
4. The roadshow. Executives travel around often literally, pitching the company to large institutional investors like fund managers and super funds, gauging how much they'd pay and how many shares they'd want.
5. Pricing. Based on all that interest, the company and its underwriters settle on an offer price which is the price the shares will first be sold at.
6. Listing day. The shares start trading on the exchange. From this moment, the price moves up and down based on supply and demand, and the company is officially public. 🎉
The one distinction that makes you sound like you get it
Here's a concept that trips people up and understanding it will genuinely help you in an interview.
When a company sells its shares at the IPO, that's the primary market: money goes from investors straight to the company. New capital, fresh in the door.
After that, when investors buy and sell those same shares among themselves on the exchange, that's the secondary market. The company doesn't get that money, it's just changing hands between investors. The share price you see quoted every day? That's the secondary market at work.
So the company raises its money once, at the IPO. Everything after is investors trading with each other. That single idea explains a lot of confusion people have about the sharemarket.
A bit of jargon, decoded
Underwriter — the investment bank(s) managing and guaranteeing the share sale.
Prospectus — the official document detailing the company before it lists.
Offer price — the price shares are first sold at in the IPO.
Float — an Australian and British term often used interchangeably with IPO ("the company floated on the ASX").
Market capitalisation ("market cap") — the total value of all a company's shares (share price × number of shares). It's how we talk about how "big" a listed company is.
Institutional investors — the big players: fund managers, super funds, insurers. They usually get first crack at IPO shares.
Why should you care as a student?
Because IPOs sit right at the intersection of the careers F3 talks about all the time. Investment bankers run them. Fund managers and analysts decide whether to buy in. Lawyers and accountants pore over the prospectus. Communications teams manage the story. An IPO is a whole ecosystem of finance roles working at once and now you can picture where you might fit. If you're still mapping the landscape, our finance career paths guide walks through the options.
