Congressional Democrats and Republicans have introduced legislation to ban prediction market bets on elections, government actions, war, and sports, as scrutiny over the platforms intensifies. The proposals come amid concerns about insider trading and corruption risks associated with these markets.
Immediate Action & Core Facts
A group of Democratic lawmakers, including Sens. Jeff Merkley (D-OR) and Elizabeth Warren (D-Mass.), and Rep. Jamie Raskin (D-Md.), introduced the STOP Corrupt Bets Act, which would prohibit bets on elections, government decisions, and military conflicts. Meanwhile, a bipartisan bill led by Reps. Adrian Smith (R-NE) and Nikki Budzinski (D-IL) aims to ban members of Congress, their families, and political appointees from trading on prediction markets related to political events.
Rep. Seth Moulton (D-Mass.) also implemented an office-wide policy barring his staff from using prediction markets like Kalshi and Polymarket, citing ethical concerns.
Deeper Dive & Context
Rationale for Legislation
Supporters of the bills argue that prediction markets create opportunities for insider trading and corruption. Sen. Merkley stated that allowing bets on government actions erodes public trust and turns democratic institutions into a "casino." Rep. Moulton echoed these concerns, calling prediction markets a "playground for corrupt insiders" who profit from geopolitical events and political outcomes.
Bipartisan Support and Penalties
The bipartisan bill introduced by Smith and Budzinski would impose fines and confiscate profits from lawmakers found violating the ban. Violators would face penalties equal to 10% of the transaction value, with funds going to the U.S. Treasury. The bill also prohibits using campaign or congressional funds to pay fines.
Industry Response
Prediction market platforms like Polymarket and Kalshi have introduced new rules to prevent insider trading and misuse of confidential information. These measures include restrictions on traders with direct influence over outcomes, such as sports participants and political candidates.
Broader Context
Prediction markets have gained popularity in recent years, allowing users to bet on a wide range of events, from sports to political outcomes. However, recent high-profile bets—such as those tied to the ouster of Venezuelan President Nicolas Maduro and the war in Iran—have raised concerns about the potential for insider trading and manipulation.
The legislation comes as separate efforts to ban insider stock trading by lawmakers remain stalled, despite bipartisan support. The last major legislation on this issue was signed into law in 2012.
