The US Senate has unanimously approved a rule prohibiting senators and Senate staff from engaging in prediction-market wagers, aiming to prevent insider trading amid growing concerns over transparency and political bias in the expanding sector.
The U.S. Senate has moved to shut its own door on prediction-market betting, approving a unanimous resolution that bars senators and Senate staff from taking part in wagers on real-world events. The rule change takes effect immediately and is designed to head off accusations that lawmakers could profit from access to sensitive or classified information, according to reporting by AP News and other outlets.
The measure was introduced by Senator Bernie Moreno, a Republican from Ohio, who framed it as a basic ethics safeguard rather than a technical market rule. Senator Alex Padilla later added an amendment extending the prohibition to staff, broadening the scope of the ban beyond elected members alone. Moreno has argued that public service should not become a vehicle for making money from event-based bets, while Senate Democratic Leader Chuck Schumer said officials should not be allowed to wager on wars, economic shocks or elections.
The Senate’s action lands amid growing scrutiny of prediction markets, which allow traders to buy and sell contracts tied to outcomes ranging from politics to conflict. According to recent reporting, concerns intensified after allegations involving trades linked to military information and other sensitive developments, prompting renewed questions about how closely these platforms intersect with government access and insider knowledge. The move is also being seen as a warning shot to a fast-expanding sector that has been attracting attention from policymakers as well as traders.
The restriction currently covers only the Senate, but lawmakers are already pressing other parts of government to follow suit. AP News reported that Schumer urged the House and the executive branch to adopt similar rules, while the broader debate continues over whether prediction markets are a useful source of public forecasting or simply another venue for speculative betting with political consequences.
