During a campaign stop for Republican House candidates in Pennsylvania, Speaker Mike Johnson warned that foreign bettors are influencing prediction markets to show a higher probability of Democrats winning control of the U.S. House of Representatives. Johnson said the influx of overseas money is pushing market odds in favor of the opposition party.
Prediction market odds
Two major prediction‑market platforms reported odds that heavily favor a Democratic victory. Kalshi, a federally regulated exchange, listed an 86% chance that Democrats will take the chamber, with more than $30 million traded on the contract. Polymarket, which operates its main exchange outside the United States, posted an 88% chance and about $10 million in trading volume.
Prediction markets differ from traditional polls because participants buy contracts that pay out if a specific outcome occurs. A contract trading at 86 cents, for example, reflects a collective belief of an 86% chance of that outcome. When the market settles, a correct contract pays $1.
Foreign participation and regulatory questions
Both platforms allow foreign users to participate. Kalshi requires identity and residence verification but does not disclose how much of its House market activity originates abroad. Polymarket claims to block U.S. users on its main exchange, though the Congressional Research Service notes lingering doubts about the effectiveness of those restrictions.
The debate over whether platforms like Kalshi constitute financial exchanges, gambling businesses, or a hybrid of both continues. Kalshi argues its contracts are regulated financial products overseen by the Commodity Futures Trading Commission (CFTC). Critics point out that many of its sports‑related contracts resemble bets offered by sportsbooks such as DraftKings and FanDuel, which are subject to state licensing, consumer‑protection rules, and gaming taxes.
Economic impact and political response
The American Gaming Association estimates that states have missed more than $1.3 billion in gaming tax revenue since prediction markets began offering sports contracts. Kalshi disputes that figure, citing federal authority granted to the CFTC.
President Donald Trump has voiced support for Kalshi’s position, emphasizing the importance of keeping exclusive CFTC authority over prediction markets. However, lawmakers from both parties have introduced the Prediction Markets Are Gambling Act, which would bar CFTC‑regulated exchanges from offering contracts that resemble sports bets or casino games.
House leadership stance
While Speaker Johnson has not called for a public ban on prediction markets, he indicated in May that he would back legislation prohibiting members of Congress and their staff from trading in these markets, citing concerns about insider information.
National polling aligns with the market odds. The Silver Bulletin’s generic congressional ballot showed Democrats ahead by 6.6 percentage points as of Tuesday. Republicans currently hold a narrow 220‑215 majority in the House, meaning Democrats need a net gain of just three seats to regain control in the 2026 midterms.
Broader context
Johnson’s comments arrive amid heightened scrutiny of prediction markets from both Republicans and Democrats. Last month, a bipartisan coalition of 44 state attorneys general urged the CFTC to clarify its authority over state‑regulated sports betting, highlighting the ongoing tension between federal and state regulatory regimes.
As the 2026 elections approach, the interplay between foreign participation in prediction markets, regulatory battles, and partisan narratives will likely remain a focal point for both policymakers and voters.
