U.S. Senate unanimously bans members from prediction market trading
Resolution passed amid concerns senators could exploit non-public information on government decisions.
Briefing
- •The U.S. Senate unanimously passed a resolution barring senators from trading on prediction markets, effective immediately.
- •The ban addresses insider-trading concerns, given senators' access to non-public information on legislation, military actions, and policy decisions.
- •The move follows instances in which online gamblers recorded significant gains betting on U.S. Government decisions, including those linked to military actions.
- •The resolution applies specifically to senators; it is not yet clear whether equivalent restrictions cover other members of Congress or their staff.
Analysis
- →The unanimous Senate resolution, combined with the CFTC's five-state litigation campaign to assert federal jurisdiction over prediction markets, creates a compound regulatory tightening signal. State AGs arguing for consumer protection oversight and the Senate acting on insider-trading concerns reinforce each other's political legitimacy. Kalshi and Polymarket face a tightening corridor: federal preemption is contested, and now Congress is actively restricting participation, reducing the addressable political-event market even if CFTC wins jurisdictional authority.
Historical Context
- 2021-2022
Widespread public and media attention on congressional stock trading, including Speaker Pelosi's options trades, generated bipartisan support for trading bans that ultimately stalled in the House. The political dynamic of unanimous Senate support followed by House inaction is a direct precedent for what may follow this resolution.
- 2012
The STOCK Act banned members of Congress from trading on material non-public information obtained through their official roles. It did not cover prediction markets, which did not yet exist at scale, creating the regulatory gap this Senate resolution now partially addresses.

CFTC sues Wisconsin in fifth state lawsuit over prediction market jurisdiction
The CFTC's fifth state lawsuit against Wisconsin to assert federal jurisdiction over prediction markets means the Senate ban lands while the foundational legal question of who regulates these platforms remains unresolved. Congressional legitimization of restrictions on prediction market participation could be cited by state AGs in ongoing litigation as evidence of congressional intent favoring tighter oversight.
CFTC sues New York to assert exclusive federal jurisdiction over prediction markets
The CFTC's suit against New York, filed after New York targeted Coinbase and Gemini over prediction market contracts, is directly compounded by the Senate action. State regulators can now argue that even Congress views political prediction markets as requiring participant restrictions, bolstering the consumer-protection framing in the 37-state AG amicus brief.
