Recent U.S. policy encourages anchor investments to facilitate initial public offerings (IPO) and increase companies' access to external finance. As access to external funds relies on stocks remaining listed, we study anchor investors' impact on how long IPOs stay listed. We examine two types of anchor investors in Hong Kong: strategic and cornerstone investors, that are similar to U.S. anchor investors, but make varying levels of commitment at and post-IPO. We find that IPOs backed by more committed investors, with longer post-IPO commitments (lockups), stay listed longer. This suggests that the success of U.S. policies may require investors' commitment.
