From tech disruptors to defence contractors, some of the market's most talked-about companies start their public journey through an initial public offering (IPO). For traders, these initial public listings can represent a unique trading environment, but also a period of heightened uncertainty.
Quick facts
- An IPO is when a private company lists its shares on a public stock exchange for the first time.
- IPOs can offer traders early access to high-growth companies, but come with elevated volatility and limited price history.
- Once listed, traders can gain exposure to IPO stocks through direct share purchases or derivatives such as contracts for difference (CFDs).
What is an initial public offering (IPO)?
An IPO is when a company offers its shares to the public for the first time.
Before performing an IPO, shares in the company are typically only held by founders, early employees, and private investors. Going public makes the shares available to be purchased by anyone.
Depending on the size of the company, it will usually list its public shares on the local stock exchange (for example, the ASX in Australia). However, some large-valuation companies choose to only list on a global stock exchange, like the Nasdaq, no matter where their main headquarters is located.
For traders, IPOs are generally the first opportunity to gain exposure to a company’s stock. They can create a unique environment with increased volatility and liquidity, but also carry heightened risk, given the limited price history and sensitivity to sentiment swings.
Why do companies go public?
The biggest driver to perform an IPO is to access more capital. Listing on a public exchange means the company can raise significant funds by selling shares.
It also provides liquidity for existing shareholders. Founders, early employees, and private investors often sell a portion of their existing holdings on the open market, realising the returns on their years of support.
Beyond the monetary benefits, going public means companies can use their stock as currency for acquisitions and offer equity-based compensation to attract talent. And a public valuation provides a transparent benchmark, which is useful for strategic positioning and future fundraising.
However, it does come with trade-offs. Public companies must comply with ongoing disclosure and reporting obligations, and pressure from public shareholders can become a barrier to long-term progress if many are focused on short-term performance.

How does the IPO process work?
While the specifics vary by jurisdiction, going from a private company to a public listing generally involves the following stages:
1. Preparation
The company first selects the underwriter (typically an investment bank) to manage the offering. Together, they assess the company's financials, corporate structure, and market positioning to determine the best approach for going public. It is the heavy planning stage to make sure the company is actually ready to go public.
2. Registration
Once everything is prepared, the underwriters conduct a thorough due diligence check and then lodge the required disclosure documents with the relevant regulator. These documents give a detailed disclosure to the regulator about the company, its management, and its proposed offering. In Australia, this is typically a prospectus lodged with ASIC; in the US, a registration statement filed with the SEC.
3. Roadshow
Executives at the company and underwriters will then present the investment case to institutional investors and market analysts in a “roadshow”. This showcase is designed to gauge demand for the stock and help generate interest. Institutional investors can register their interest and valuation of the IPO, which helps inform the initial pricing.
4. Pricing
Based on feedback from the roadshow and current market conditions, the underwriters set the final share price and determine the number of shares to be issued. Shares are allocated on the ‘primary market’ to investors participating in the offer (before the stock is listed publicly on the secondary market). This process sets the pre-market price, which effectively determines the company’s initial public valuation.
5. Listing
On listing day, the company’s shares begin trading on the chosen stock exchange, officially opening the secondary market. For most traders, this is the first point at which they can trade the stock, either directly or through derivatives such as Share CFDs.
6. Post-IPO
Once listed, the company becomes subject to strict reporting and disclosure requirements. It must communicate regularly with shareholders, publish its financial results, and comply with the governance standards of the exchange on which it is listed.
IPO risks and benefits for traders
How do traders participate in IPOs?
For most traders, participating in an IPO comes once shares have listed and begun trading on the secondary market.
Once shares are live on the exchange, investors can buy the physical shares directly through a broker or online exchange, or they can use derivatives such as Share CFDs to take a position on the price without owning the underlying asset.
The first few days of IPO trading tend to be highly volatile. Traders should ensure they have taken appropriate risk management measures to help safeguard against potential sharp price swings.
The bottom line
IPOs mark when a company becomes investable to the public. They can offer early access to high-growth companies and create a unique trading environment driven by elevated volatility and market interest.
For traders, understanding how the process works, what drives pricing and post-IPO performance, and how to weigh potential rewards against the risks of trading newly listed shares is essential before taking a position.
