The U.S. Senate recently took a major step by directly banning senators from participating in prediction markets.

This resolution is only 14 lines long but was passed unanimously and took effect immediately.

The background is as follows: prediction platforms like Polymarket and Kalshi have become extremely popular recently, allowing politicians to bet on election outcomes, bill passage, and even geopolitical events.
As a result, some started betting on their own re-election campaigns and got caught. Ohio Republican Senator Bernie Moreno couldn’t stand it and pushed for this resolution.

The new rule is clear: Senators and their staff are prohibited from engaging in "any trading based on the occurrence or non-occurrence of specific events."
In plain terms, they can’t use prediction markets to line their pockets. Moreno emphasized in a statement that serving in Congress should be about doing real work for the American people, not finding new ways to get rich.

Interestingly, Polymarket had already reached a settlement with the U.S. Commodity Futures Trading Commission in 2022, effectively banning U.S. users from trading.
This time, the law codifies the ban, and platforms say it’s a step forward for the industry.
Currently, the market predicts about a 50% chance that Democrats will retake the Senate majority in this year’s midterm elections, tied with Republicans.

What do you think— is this further tightening of regulation, or just the necessary oversight?
