Highlights

Prediction markets are creating new insider trading risks, prompting some firms—most notably Goldman Sachs—to restrict employee trading on event contracts. This development has already led to enforcement action, and legal advisors warn that companies should adopt clearer policies and employee training now to avoid future liability. Exchanges and monitoring firms are beginning to add detection and verification tools, but many businesses remain in the early stages of updating internal rules.

Prediction markets—platforms where participants place bets on the outcomes of events such as elections, corporate milestones, or economic indicators—are introducing a fresh set of compliance challenges for companies. Firms in highly regulated sectors, especially banks, are already grappling with how these markets interact with existing insider trading rules. Some organizations have moved quickly: for example, Goldman Sachs has prohibited employees from trading on contracts tied to the bank itself and on a range of related topics, including elections, financial markets, macroeconomic releases, and geopolitics. The bank reiterated that employees are barred from using material, nonpublic information to trade across any market.

Regulatory scrutiny has sharpened after recent enforcement actions. In one notable case, the Commodity Futures Trading Commission and the Department of Justice charged a Google employee with using confidential information to place profitable trades on an event market. According to regulators, that individual obtained roughly $1.2 million in gains by wagering on outcomes tied to internal company information. Such incidents highlight how the vast variety of available contracts can expose previously hidden information to trading strategies: an employee with access to internal product timelines, hiring numbers, or financial forecasts might exploit that knowledge on specialized markets.

Legal specialists warn that the breadth of contracts available on prediction platforms makes it difficult to anticipate every potential misuse of confidential data. A single company may appear across dozens of question types—headcount, product releases, stock-price movements—making targeted enforcement and internal policing a complicated task. As prosecutions mount, lawyers say there will be growing expectations that employers maintain clear policies and training to mitigate liability when employees trade on these platforms.

Despite these concerns, many companies have not yet adopted formal policies specific to prediction markets. In outreach to a mix of public and private firms that have market contracts referencing their businesses, only a small fraction reported having explicit rules; a couple more said they were reviewing the issue. Several big banks noted either existing guidance that cautions staff or updates in progress to clarify prohibited activities. Others rely on broad insider trading prohibitions in their codes of conduct, which technically cover the misuse of nonpublic information in any market, including event contracts.

Exchanges and third-party vendors are also taking steps to reduce abuse. Some platforms have introduced employment verification, surveillance partnerships, and integrations with compliance software so employers can monitor staff trading. Market integrity firms and blockchain analytics companies are being engaged to detect suspicious patterns. Yet industry observers caution these measures are preliminary: they can help identify anomalous trades, but they do not replace employer-led training and explicit policy language prohibiting certain participation.

The regulatory picture remains unsettled. Agencies such as the CFTC are active, but precedent in this specific space is limited, leaving regulators with a relatively open field to define enforcement approaches. This uncertainty makes it important for businesses to be proactive. Experts recommend updating insider trading policies to explicitly reference event contracts, creating monitoring protocols for markets tied to the company, and educating employees about the risks. Some advisers even suggest stronger steps, like restricting platform access on corporate devices or barring trading during work hours for higher-risk roles.

Ultimately, the rise of prediction markets presents a distinct challenge for corporate compliance programs. Organizations that ignore the issue risk enforcement, reputational harm, and legal exposure. Companies that engage early—by clarifying rules, training staff, and coordinating with exchange monitoring tools—are better positioned to manage the evolving risk landscape as these markets continue to grow.
