The U.S. House Committee on Oversight and Government Reform has recommended Congress legislate to restrict or ban federal government personnel, members of Congress, and their staff from trading on prediction markets. The recommendation follows the committee's investigation into insider trading in the sector, with proposed options ranging from a complete ban to restrictions on trading government-related contracts. In its memorandum, the committee disclosed it obtained nearly 1,700 pages of documents and received briefings from five prediction market platforms. Most insider trading incidents were discovered and reported by the platforms themselves, while Polymarket and Kalshi are continuously improving their surveillance mechanisms to detect such activity.
