Polymarket buckles down on insider trading after scrutiny over suspiciously timed bets
Polymarket, a popular prediction market platform, is taking steps to crack down on insider trading amidst increasing scrutiny over the use of classified or confidential information to gain an unfair advantage in betting on events. The New York-based company recently announced updated rules that prohibit trades based on stolen confidential information or illegal tips. Additionally, traders are now prohibited from placing bets if they hold a position of authority or influence that could sway the outcome of a particular event.
For instance, CEOs of public companies are not allowed to trade on markets that focus on predicting how many times they will use a specific word during an earnings call with analysts. These new rules, which are available on Polymarket’s website under a “market integrity” page, apply to both its U.S. exchange and offshore operations.
The surge in popularity of prediction market platforms like Polymarket and its competitor, Kalshi, has raised concerns among lawmakers and critics who question their compliance with anti-gambling regulations and the integrity of trading activities on these platforms. Stephen Piepgrass, a partner at Troutman Pepper Locke who leads the law firm’s regulatory practice, highlighted concerns regarding trading on the U.S. market from outside the U.S. borders and vice versa, prompting the need for a comprehensive approach to regulation.
Polymarket has implemented a robust monitoring system and collaborates with surveillance and technology specialists to identify any violations of its terms of use. The platform has outlined various steps it can take if it detects suspicious trading activity, including reporting the matter to law enforcement and enforcing disciplinary actions.
The company’s recent move to strengthen rules against insider trading comes in response to incidents where customers made well-timed bets on events like the capture of former Venezuelan President Nicolás Maduro and the outbreak of war in Iran, raising suspicions of insider trading. Senator Ruben Gallego even referred to such activities as “insider trading in broad daylight.”
To stay ahead of potential regulatory actions, Polymarket and Kalshi are proactively enhancing their rules against insider trading. The Commodity Futures Trading Commission, which oversees prediction markets, recently issued guidance on measures prediction markets should take to prevent insider trading. This has prompted both platforms to tighten their policies and implement new technologies to detect and prevent insider trading and market manipulation.
In conclusion, Polymarket’s efforts to strengthen its rules against insider trading reflect a proactive approach to maintain market integrity and compliance with regulatory standards. By implementing stricter regulations and leveraging advanced monitoring systems, the platform aims to ensure fair and transparent trading for all participants.
