According to Cointelegraph, a Republican lawmaker has introduced a bill aimed at restricting insider trading activity connected to prediction markets. The proposal focuses on certain kinds of wagers made through those platforms, while leaving several categories outside the specific prohibitions described in the report.

Policy wagers are the central target
The bill does not specifically prevent members of the US Congress from using prediction market platforms. It also does not specifically bar them from placing sports bets. Instead, the reported restriction is directed at policy wagers, meaning bets tied to policy matters.
The measure also does not include White House officials in the prediction markets insider trading ban, according to the article title and summary. Based on the details provided, the proposal treats platform use, sports betting and policy-related wagers as separate issues, with the explicit ban focused on policy wagers rather than a broader prohibition on all prediction market activity by government figures.
