Fewer companies are going public in the United States, but public companies are still the focus of securities law and enforcement. A major exception is that anti-fraud provisions apply to all companies, public or private. Theranos is a prominent example. The Securities and Exchange Commission (“SEC”) sued this private company for securities fraud. This Article examines one societal cost of the decline of public companies: the loss of information needed to detect and punish fraud. It analyzes the SEC’s securities fraud enforcements against private companies and assesses the information costs of moving to an anti-fraud-only regime. It concludes by identifying ways to incentivize information disclosure in the newly private universe of corporations, including a proposal to expand whistleblower protection for employees of private companies.
