On Wednesday, the House Administration Committee swung in a straight‑line partisan vote to move forward with the Stop Lawmakers from Predicting Act, a bill that would bar members of Congress, their spouses and dependent children from trading on Washington‑focused prediction markets.

The motion passed just hours before this story was filed, underscoring how deeply the House is divided over the scope of ethical safeguards for lawmakers. Republicans, in a unanimous block, endorsed the measure, while Democrats cast a single, united vote against it.

House Administration Chair Rep. Bryan Steil (R‑WI) introduced the bill, framing it as a necessary step to eliminate the possibility that lawmakers could profit from inside knowledge. “Lawmakers elect to serve the American people, not to enrich themselves by wagering on outcomes from the decisions they make,” Steil said. “We have a real opportunity to restore trust in Congress by taking necessary steps to eliminate even the appearance of impropriety.”

Rep. Joseph Morelle (D‑NY) countered that the proposal falls short of the Senate’s earlier action. He pointed to the April 30 resolution that immediately barred senators, their staff and other chamber officials from trading on prediction markets such as Kalshi and Polymarket, noting that it required no grace period or protracted procedural steps. “The Senate did it in a matter of minutes—no six‑month grace period, no procedurally laborious process,” Morelle said. “They just went to the floor with a two‑page resolution and banned it all unanimously. We should do the same.”

The Senate’s ban followed a string of high‑profile incidents that raised concerns about insider trading, including trades timed around the capture of former Venezuelan leader Nicolás Maduro, shifts in Google search results, and the Iran war. Those events prompted senators to take swift, decisive action.

While the House bill mirrors the Senate’s effort, it is narrower in focus. It targets only markets that allow bets on elections or government actions, leaving sports and other non‑policy prediction markets untouched. Steil acknowledged that a broader prohibition could extend to scenarios such as a member’s child betting on a sporting event through a prediction market platform, but the current language limits the scope to policy‑related markets.

The committee vote reflected a broader debate within the House about balancing ethical safeguards against the rights of members to engage in private financial activities. All Republican members voted in favor, and all Democratic members voted against, illustrating the clear partisan split.

At present, the Stop Lawmakers from Predicting Act remains in committee. If it advances to the full House floor, it will likely face another party‑line split. No official timetable has been set for when the House might consider the measure.

By contrast, the Senate’s resolution was adopted unanimously and took effect immediately, banning senators and their staff from trading on any prediction market that allows bets on political or policy outcomes.

The House bill’s passage would align the chamber’s rules more closely with the Senate’s stricter stance on prediction markets. Whether the House will follow the Senate’s example remains uncertain, but the committee vote signals that the issue is a priority for many Republican members.

In the coming weeks, observers will watch for any further actions by the House Administration Committee and the full House. The debate over prediction markets highlights ongoing concerns about insider trading, ethics, and the appearance of impropriety among elected officials.

The current status is that the Stop Lawmakers from Predicting Act is under consideration by the House Administration Committee. The next steps will involve potential hearings, amendments, and a vote by the full House. The Senate’s ban remains in effect, and no changes to that resolution have been announced.
