The primary market is where new securities (usually shares, through an IPO) are created and sold directly by a company to investors for the first time. The money raised goes straight to the company, which is why companies use the primary market to fund growth, expansion, or debt repayment.
Key Feature
This is a one-time event per share issuance — it’s not something that happens every day like regular stock market trading. Once the shares are sold and listed, all further trading happens in the secondary market instead.
Example
When you apply for shares during a company’s IPO, you are participating in the primary market — your money, if your application is accepted, goes to the company itself.
