The bill proposes to prohibit government officials from using insider information to bet on prediction market contracts, with fines up to double the amount of profits.
US lawmakers have introduced a second bill this week aimed at curbing prediction market insider trading by government officials, amid growing concerns over such activity on major platforms such as Kalshi and Polymarket.
In an announcement on Thursday, US lawmakers Todd Young, Elissa Slotkin, John Curtis and Adam Schiff unveiled the bipartisan Public Integrity in Financial Prediction Markets Act of 2026.
“No one should be profiting off the information and knowledge gained as a public servant, period,” Slotkin said, adding: “This bill is an important first step in placing common sense rules around prediction markets, and it has real teeth to ensure those who break these rules face real consequences.”
