The Public Stock Market Isn’t Enough Anymore

The sharp division between public and private securities was a major bulwark of financial regulation from the New Deal in the 1930s to the end of the 20th century. Securities that could be sold to anyone had extensive disclosure and investor-protection rules, while private securities that were available only to sophisticated institutions and wealthy individuals had limited regulatory oversight. For a quarter century, cracks have been appearing in the dam separating public from private. Now we appear to be poised on the brink of a complete dam break.

Deloitte estimates that within five years, US and European retail investors will hold $5.4 trillion of investment in private companies, up from under $1 trillion today, if recent trends hold. This will constitute a significant fraction of all retail investment.

Under current US rules, little of this will be direct. Instead, retail investors will have a menu of indirect offerings to choose from: exchange-traded funds from asset managers such as Invesco Ltd. and ProShares, special purpose acquisition companies, derivatives, mutual funds, interval funds, blocker corporation shares and other products. The race to tokenize exposure to companies such as SpaceX and OpenAI for retail investors made headlines recently. In addition, investors will get more indirect exposure via investments by their pension funds and other retirement instruments.

This raises two questions. Is the traditional distinction between public and private investments worth defending? And should regulators encourage an officially approved mechanism for investment or let the market experiment, relying on the survival of the fittest to produce the best result?

One issue is that the old regulatory structure was designed under the assumption that the pressure for private investment came from businesses wanting inexpensive retail capital without the trouble and expense of meeting public investment rules. The situation today is the reverse, the pressure is coming from retail investors, who want exposure to the hottest sectors, pushing money onto private companies that don’t want it. An equally important pressure is coming from intermediaries, anxious to earn fees with creative ways to force retail money on hot private enterprises.
