Primary vs secondary market
4 min
One of the most important distinctions in finance is where the money goes when a security changes hands. That depends on whether the trade happens in the primary or the secondary market.
The primary market
The primary market is where a security is created and sold for the first time, and the money goes to the issuer.
- A company holding an IPO (initial public offering) sells brand-new shares; the cash raised funds the company.
- A government or company issuing bonds receives the money lent by buyers.
This is the market that actually funds the real economy — it is the moment capital flows from investors into businesses and governments.
The secondary market
The secondary market is where those already-issued securities are traded among investors. When you buy a share on B3, you are almost always buying it from another investor, not from the company — the company gets none of that money.
- It provides liquidity: you can sell when you want, because someone else is willing to buy.
- It provides price discovery: continuous trading reveals what the security is worth right now.
Why both are needed
The two depend on each other. Investors will only buy new securities in the primary market if they believe they can later sell them in a liquid secondary market. A vibrant secondary market is therefore what makes primary fundraising possible — and most of the trading you will ever do happens in the secondary market.
