House Republicans Seek Limits on Election Prediction Market Trades

TLDR

• House GOP seeks limits on lawmakers’ election Prediction Market trades.

• Steil moves to add Prediction Market rules to stock trading bill.

• Polymarket and Kalshi face new scrutiny over political wager risks.

• Congress weighs Prediction Market limits amid insider trading concerns.

• H.R. 7008 may expand from stock bans to political betting limits.

House Republicans want to add Prediction Market limits to a stalled congressional stock trading ban, widening scrutiny of lawmakers’ financial activity. The planned changes would target election and public policy wagers, while leaving other contracts outside the main restriction. The move adds pressure on platforms such as Polymarket and Kalshi as Congress reviews market integrity risks.

Steil Seeks Prediction Market Rules in Stock Trading Bill

House Administration Committee Chair Bryan Steil plans to attach the new language to H.R. 7008 before a floor vote. The bill already seeks to restrict lawmakers, spouses, and dependents from buying publicly traded stocks. Besides, it would require public notices before stock sales and impose penalties for violations.

The proposed Prediction Market language would not create a full ban on lawmakers using such platforms. Instead, it would limit contracts tied to elections, government action, and public policy outcomes. However, sports and entertainment contracts would remain allowed under Steil’s stated approach.

Steil has argued that Congress still lacks clear rules for lawmakers using Prediction Market platforms. His position reflects wider concern that elected officials could wager on matters they influence. Hence, the proposal links prediction contracts to the same ethics concerns behind the stock trading ban.

Polymarket Scrutiny Adds Pressure on Congress

The debate has grown as Polymarket faces new attention over paid online promotion and political betting. Politico reported payments linked to the company’s chief marketing officer and later posts by several creators. Moreover, some posts allegedly promoted Polymarket without clear disclosure of financial ties.

Polymarket became widely known during the 2024 election cycle after users bet on Donald Trump’s victory. Supporters argue that Prediction Market platforms can reflect public expectations in real time. Yet critics warn that election contracts can raise gambling, disclosure, and insider-style trading concerns.

Congressional pressure increased after House Oversight Committee Chair James Comer opened investigations into Polymarket and Kalshi. Comer cited a growing pattern of insider trading concerns on Prediction Market platforms. Additionally, lawmakers have pointed to alleged wagers tied to military activity as a national security concern.

Ban Effort Moves Toward a Possible House Vote

H.R. 7008 cleared committee steps in February and remains eligible for House debate. Steil expects House leaders to schedule a vote during the summer session. If added, the Prediction Market language would broaden the bill beyond traditional stock trading restrictions.

The Senate has already passed a resolution banning members from using prediction platforms. Meanwhile, White House aides reportedly received instructions in March not to place wagers on such markets. Consequently, the House proposal would align with a wider federal push for tighter conduct rules.

The stock trading bill would ban lawmakers and close family members from purchasing public stocks. It would also require seven-day public intent notices before sales. Therefore, adding Prediction Market limits would extend the bill’s ethics framework into newer political betting markets.
