Secondary Market
The secondary market is where previously issued securities -- stocks, bonds, fund interests, or startup equity -- are bought and sold among investors, rather than from the original issuer. In public markets this is a stock exchange; in private markets it refers to transactions where existing shareholders sell stakes to new buyers without the company issuing new shares. Secondary sales provide liquidity to early shareholders while leaving the company's capitalization table otherwise unchanged, though most private secondary transactions require company consent and may trigger rights of first refusal.
Problem & Application
Startup founders, early employees, and angel investors in pre-IPO companies frequently face illiquidity for years after initial investment. Secondary market transactions -- whether through platforms facilitating private share sales or direct buyer introductions -- allow these holders to realize partial liquidity without a full exit event. The tax treatment of a secondary sale depends on how long shares were held, whether they were ISOs or NSOs, and the applicability of qualified small business stock exclusions. PE-backed portfolio companies also use secondary market transactions at the fund level when LPs need to exit positions early. Navigating consent rights, valuation, and 409A implications requires careful preparation.
In Short
The secondary market unlocks liquidity that private ownership otherwise denies. Sellers benefit from understanding their cap table rights, tax exposure, and valuation basis before agreeing to a transaction that cannot easily be undone.
