US Senate Bans Lawmakers from Prediction Markets Amid Growing Crypto Betting Scrutiny

The U.S. Senate has swiftly passed a new rule prohibiting senators from participating in prediction markets, signaling a sharp contrast to its slower progress on broader crypto market structure legislation. The move came through a concise 14-line resolution introduced by Ohio Republican Senator Bernie Moreno and was approved unanimously, highlighting bipartisan concern over ethics and financial conduct in emerging betting platforms.

The new rule takes immediate effect and prevents senators from engaging in any agreement, contract, or transaction tied to the outcome of specific events. This includes buying, selling, or receiving payments based on whether an event occurs or how it unfolds. The restriction directly targets the rising popularity of prediction markets, which allow users to bet on real-world outcomes such as elections, economic trends, and geopolitical developments.

Senator Moreno emphasized that public officials should avoid speculative financial activities while serving in government. He stated that lawmakers should focus on delivering results for citizens rather than seeking personal financial gain through platforms that may present conflicts of interest. The decision comes amid increasing scrutiny of insider trading risks and ongoing debates about regulatory oversight in the crypto and betting sectors.

Prediction markets have grown rapidly, with platforms like Polymarket gaining global attention despite regulatory challenges in the United States. Polymarket, which reached a settlement with the Commodity Futures Trading Commission (CFTC) in 2022 restricting its U.S. operations, publicly supported the Senate’s action. The company noted that its internal policies already prohibit such activity among certain participants, and it welcomed the formalization of these standards into law.

Interest in political betting continues to rise, with some candidates previously facing penalties for wagering on their own campaigns. Current market trends on platforms like Polymarket even show shifting odds on party control of the Senate, reflecting how influential these markets have become.

As the crypto industry evolves, this decision underscores growing regulatory attention and ethical concerns surrounding prediction markets, reinforcing the need for clear boundaries between public service and financial speculation.
