Senate Unanimously Bans Members From Betting On Prediction Markets

A rare bipartisan agreement emerged in the U.S. Senate this week as lawmakers unanimously approved a new rule prohibiting senators and Senate staff from participating in prediction markets, amid growing concerns about insider information and public corruption. The measure took effect immediately following a voice vote that encountered no opposition.

The resolution was introduced by Bernie Moreno and later expanded through an amendment offered by Alex Padilla to ensure the restrictions also applied to Senate employees and officers.

Lawmakers from both parties argued that individuals with access to confidential government information should not be allowed to profit from wagers tied to political events, military operations, elections, or economic developments.

“United States senators have no business engaging in speculative activities like prediction markets while collecting a taxpayer-funded paycheck, period,” Moreno said while urging immediate passage of the rule change.

The issue gained urgency after federal prosecutors charged a U.S. special forces soldier with allegedly using classified information to place bets connected to the operation that led to the capture of Venezuelan leader Nicolás Maduro. Authorities allege the suspect profited substantially from advance knowledge of the military operation.

Additional scrutiny followed reports of suspiciously timed wagers involving a potential ceasefire between the United States and Iran, raising fears that individuals with privileged diplomatic or military information could financially benefit before the public became aware of major developments.

Senate Minority Leader Chuck Schumer called the measure a “no-brainer” and warned against allowing Congress to profit from national crises.

“We must never allow Congress to turn into a casino where members representing the public can gamble on wars or economic crises or elections,” Schumer said. “That would destroy the very principle of representative government.”

Because the measure was adopted as a Senate rule change rather than federal legislation, it did not require approval from the House or a signature from current President of the United States Donald Trump. The restriction now applies immediately to senators, Senate staff, and Senate officers only.

Critics and reform advocates note, however, that the policy leaves major gaps. Members of the House of Representatives, executive branch officials, and much of the federal workforce remain outside the scope of the Senate rule despite many holding access to highly sensitive information.

To address that concern, Todd Young and Elissa Slotkin have introduced broader legislation that would prohibit federal officials from using insider information for speculative betting activities.

The Senate Ethics Committee is expected to oversee enforcement of the new rule, though lawmakers have yet to outline detailed penalties for violations. Some observers remain skeptical about whether Congress will aggressively police its own members given the historically weak enforcement of congressional ethics standards.

Meanwhile, the House has not adopted a similar restriction, and it remains unclear whether Mike Johnson will move forward with parallel action.

Even so, the unanimous Senate vote represents one of the few recent examples of bipartisan consensus on ethics reform in Washington. Supporters argue the move sends a strong message that lawmakers should not personally profit from access to sensitive information tied to war, elections, or national economic policy.
