House Agriculture Committee Ranking Member Angie Craig (MN-02) led a bicameral letter with Senate Banking Committee Ranking Member Elizabeth Warren (D-MA), Senate Agriculture Committee Ranking Member Amy Klobuchar (D-MN) and House Financial Services Committee Ranking Member Maxine Waters (D-CA-43) to the Commodity Futures Trading Commission (CFTC) and the Office of Government Ethics (OGE), encouraging them to clamp down on insider trading by federal employees in the Trump administration.
Prediction markets have grown quickly in recent years, allowing users to bet on the outcome of political, economic and geopolitical events. Recent reports of last-minute bets being placed to reap large payoffs on obscure events seem to indicate nonpublic government information has been used by those with insider information.
“Over the weekend of January 3-4, 2026, a Polymarket user made $400,000 by betting on the capture of Venezuela’s former leader, Nicolás Maduro, raising suspicions that the user traded with insider government knowledge,” the lawmakers write.
Federal law prohibits government employees from using nonpublic information obtained through their official duties for personal financial gain through prediction markets.
The lawmakers who joined the letter include Representatives Salud Carbajal (D-CA-24), André Carson (D-IN-07), Marcy Kaptur (D-OH-09), John Mannion (D-NY-22), James McGovern (D-MA-02), Seth Moulton (D-MA-06), Eleanor Holmes Norton (D-DC-At-large), Andrea Salinas (D-OR-06), Eric Sorensen (D-IL-17), Suhas Subramanyam (D-VA-10), Mike Thompson (D-CA-04), Gabe Vasquez (D-NM-02), Eugene Vindman (D-VA-07) and Dina Titus (D-NV-03) and Senators Cory Booker (D-NJ), Catherine Cortez Masto (D-NV), Ruben Gallego (D-AZ), Kirsten Gillibrand (D-NY), John Hickenlooper (D-CO), Andy Kim (D-NJ), Mark Warner (D-VA), Raphael Warnock (D-GA), Jeanne Shaheen (D-NH) and Jeff Merkley (D-OR).
Since she came to Congress, Ranking Member Craig has led the charge to fight corruption and restore integrity to Washington, DC.
Last year, she reintroduced her NO STOCK Resolution, which would require members of Congress to immediately sell their individual stocks and refrain from future stock ownership while in office.
She also joined her colleagues in introducing the “End Corruption Now” legislative agenda, which aims to confront political corruption and clean up government through six bills that put power back in the hands of the American people. These bills will prevent the president, executive branch officials and members of Congress from personally benefiting from their offices.
Earlier in the 119th Congress, she reintroduced her Halt Unchecked Member Benefits with Lobbying Elimination (HUMBLE) Act–a broader package of reforms that would ban members of Congress from owning or trading individual stocks, prohibit the use of taxpayer funds for first-class airline tickets, prevent members from serving on corporate boards while they are in Congress, eliminate access to members-only perks for former members and eliminate automatic pay raises for members of Congress. She first introduced the HUMBLE Act during her first term in Congress in 2019.
