This session examines the rise of informed trading on prediction markets such as Kalshi and Polymarket, where people now bet on elections, corporate events, government actions, and pop culture. Growth on these platforms has brought a wave of trades that appear to rely on classified, corporate, or other nonpublic information. The session draws on the speaker’s own study of Polymarket contracts, which flagged more than 210,000 suspicious bets with about 70% win rates and an estimated $143 million in profits. It explains why this activity is so hard to detect, how the same markets can be moved by false rumors and coordinated trading, and who has authority to police it: the CFTC, the states, or the platforms themselves. It also covers the new risk for companies whose employees can bet on their employer’s product launches, earnings, deals, or leadership changes. Attendees will leave with a practical framework for advising platforms, companies, and individuals in this fast-moving area.
This session addresses how insider trading law is expanding past the traditional tipper–tippee case. Regulators and plaintiffs now pursue shadow trading, meaning trades in other companies’ stock based on confidential information from one’s own company. They are also looking closely at trades made under 10b5-1 plans and at unusual trading before cybersecurity breaches and activist campaigns. At the same time, statistical and machine-learning tools can spot suspicious trading patterns that would have gone unnoticed ten years ago. The session covers the legal theories expanding liability, what the data shows about informed trading in stock markets, how regulators and litigants use trading-pattern analysis as evidence, and how that evidence can be challenged in court. Attendees will leave with concrete steps for building insider trading compliance programs that hold up under this new level of data-driven scrutiny.
