Prediction markets allow participants to trade contracts on whether or not real-world events will occur. These platforms have grown rapidly, and contracts tied to specific company activity are now actively trading, including contracts on IPOs, mergers and acquisitions, earnings call mentions, and sales and subscriber metrics. While most public companies have adopted insider trading and related policies to regulate trading in the company’s securities, companies’ policies are generally written for securities transactions, where prediction market event contracts are generally not offered or traded as securities in the traditional sense. That gap matters, as companies still need to guard against misuse of company information in the context of other transactions, such as events contracts. Trading on the basis of nonpublic information on prediction markets may attract enforcement at multiple levels, including platform based sanctions, regulatory actions, and criminal charges against individuals that may have implications for public companies. This alert explains the risks, outlines what companies can do to address these risks and identifies what to watch for as the regulatory framework takes shape.
