There are three main ways a private company goes public. Each raises money differently, prices shares differently, and suits a different kind of company.
“Going public” sounds like a single event, but there are three distinct routes a private company can take to get its shares trading on a stock exchange. Each one prices the company differently, raises (or doesn’t raise) new capital differently, and suits a different situation. Knowing the difference helps you read the financial headlines with a sharper eye.
The initial public offering is the classic path. The company hires investment banks as underwriters, who help it issue new shares and sell them to investors.
The IPO raises fresh capital for the company and lets early investors sell some holdings. Its main criticism is the “IPO pop”: shares often jump on day one, which means the company sold them too cheaply and left money on the table. Underwriting fees are also significant.
In a direct listing, a company’s existing shares simply start trading on an exchange — no new shares are issued and no underwriters sell stock at a set price.
Direct listings suit well-known companies that don’t need to raise cash and want to avoid the IPO pop and banker fees. Because there’s no fixed offer price, the opening price is discovered purely by market supply and demand on the first day.
The trade-off: a traditional direct listing raises no new money for the company — it only gives existing shareholders liquidity. (Rules have evolved to allow some capital-raising direct listings, but the classic version doesn’t.) It also lacks the price-stabilising support that underwriters provide, so early trading can be volatile.
A SPAC — Special Purpose Acquisition Company — flips the order of operations. It’s a shell company with no operations that raises money in its own IPO, then goes hunting for a private company to merge with.
For the target company, a SPAC can be faster than an IPO and allows it to share forward-looking projections that are harder to use in a traditional IPO. But SPACs have a mixed track record: sponsor incentives can dilute ordinary shareholders, and many companies that went public via SPAC in the 2020–2021 boom later traded well below their merger price.
| Raises new capital | Uses underwriters | Sets a fixed price | |
|---|---|---|---|
| IPO | Yes | Yes | Yes |
| Direct listing | Usually no | No | No |
| SPAC | Yes (from the SPAC’s trust) | Sponsor-led | Negotiated |
When a company goes public, ask three questions: Did it actually raise money, or just let insiders sell? Who set the price — bankers, the market, or a negotiation? And how locked-up are existing shareholders, since a wave of selling when lock-ups expire can pressure the stock. The route a company chooses often tells you as much about its confidence and its needs as the valuation itself.
