The private company secondary market has grown significantly in recent years as more companies stay private longer. This market allows investors to purchase shares of private companies from existing shareholders. The growth of this market is helping to address the widening "IPO gap" as companies mature before going public. Secondary investors provide liquidity to shareholders of late-stage private companies and help relieve pressure for companies who face constraints on the traditional IPO path. The legal framework around private share trading is also developing to further support this growing market.
