The U.S. Senate unanimously approved a rule barring senators from trading on prediction markets immediately, citing insider trading risks and conflicts linked to event contracts on elections, conflict, violence, and other sensitive outcomes.

CNBC disclosed a commercial relationship with Kalshi, including a minority investment in the company.

Enforcement is primarily through internal ethics tools, with criminal prosecution possible if existing laws like insider trading apply.

Supporters frame the measure as a transparency and anti-corruption move, seeking an easy ethical win without broad regulatory battles.

Sponsor Sen. Bernie Moreno argued that lawmakers should not speculate with taxpayer resources, and an amendment by Sen. Alex Padilla extended the ban to include staff.

Kalshi has previously suspended several political candidates from betting on their own campaigns, reflecting ongoing scrutiny of prediction-market participation by political figures.

The policy aims to mitigate conflicts of interest and boost public trust in congressional ethics and financial conduct.

Details such as the exact text of the rule, enforcement mechanisms, or any sunset provisions are not provided in the excerpt.
