Senate bans itself from prediction markets. The compliance question just became an ethics rule.
Congress didn't just tell senators to stay off Polymarket. It embedded that restriction in its own rulebook, and that's the part that opens a wider regulatory door.

The U.S. Senate passed S. Res. 708 yesterday by unanimous voice vote, per Decrypt's April 30 report, prohibiting senators from entering any transaction whose payoff depends on the occurrence of a specific event. An amendment by Sen. Alex Padilla reportedly extended the ban to staff, though the resolution text published by sponsor Sen. Bernie Moreno's office does not reflect that language yet.
The significance isn't volume. No senator was moving the Kalshi line on a rate decision. The significance is that Congress just made prediction-market participation an ethics violation, not a conflict-of-interest talking point. That is a different kind of threat to Polymarket and Kalshi than any CFTC enforcement action.
The STOCK Act in 2012 followed this logic. Congress banned itself from trading on material non-public information gathered through legislating, and the SEC cited that logic in broader enforcement actions within two years. There is no obvious reason the prediction-market version plays out slower.
Kalshi won a federal court ruling in 2024 allowing political event contracts in the U.S. That was a CFTC jurisdiction fight. This resolution doesn't reopen that case, but it gives any regulator a new frame: prediction markets are now officially a congressional integrity problem. That gives regulators more to work with than anything the CFTC has tried to build on so far.
Either Kalshi and Polymarket get ahead of the lobbying now or the House companion rule writes the next chapter for them.
A House companion resolution or a CFTC public statement citing congressional integrity concerns as grounds for tighter oversight of political event contracts, before the end of Q2.
Forward this.
