The primary market is the part of the capital market that deals with the issuance and sale of securities to purchasers directly by the issuer, with the issuer being paid the proceeds. A primary market means the market for new issues of securities, as distinguished from the secondary market, where previously issued securities are bought and sold. A market is primary if the proceeds of sales go to the issuer of the securities sold. Buyers buy securities that were not previously traded.

In a primary market, companies, governments, or public sector institutions can raise funds through bond issues, and corporations can raise capital through the sale of new stock through an initial public offering (IPO). This is often done through an investment bank or underwriter or finance syndicate of securities dealers. The process of selling new shares to buyers is called underwriting. Dealers earn a commission that is commonly built into the price of the security offering, though it can be found in the prospectus.

Since the securities are issued directly by the company to its buyers, the company receives the money and issues new security certificates to the buyers. The primary market plays the crucial function of facilitating capital formation within the economy. The securities issued at the primary market can be issued in face value, premium value, or at par value.

Primary markets create long-term instruments through which corporate entities raise funds from the capital market. It is also known as the New Issue Market (NIM).

Once issued, the securities typically trade thereafter on a secondary market such as a stock exchange, bond market, or derivatives exchange.
