Congress is finally closing a loophole that allowed lawmakers to gamble on wars, elections, and government decisions using insider knowledge—turning the people’s house into a potential casino for the well-connected.
Story Snapshot
- Senate unanimously passed legislation banning members and staff from trading on prediction markets after suspicious bets preceded a U.S. military strike on Iran
- Bipartisan PREDICT Act introduced in House would extend restrictions to all federal officials, preventing exploitation of classified information for personal profit
- Major platforms Kalshi and Polymarket suspended three political candidates for insider trading, including one who bet on his own election before announcing candidacy
- Public overwhelmingly supports restrictions with 70% approval, viewing government officials profiting from insider information as betrayal of public trust
The Iran Strike That Exposed a Dangerous Loophole
Late February 2026 marked a turning point when anonymous bettors placed suspicious wagers on prediction markets just hours before the United States launched a military strike on Iran. The incident revealed a glaring vulnerability in financial regulations: government officials with access to classified information could legally profit from betting on events they helped orchestrate. This wasn’t theoretical corruption—it was happening in real-time. The Department of Justice subsequently charged a U.S. soldier for using Polymarket to bet on a Venezuelan raid he participated in, confirming that insider trading on these platforms had already taken root within government ranks.
Bipartisan Action to Stop “Casino Congress”
The Senate responded with rare unanimity, passing legislation that bans senators and staff from trading on prediction market platforms. Senate Minority Leader Chuck Schumer captured the stakes plainly: “We must never allow Congress to turn into a casino where members representing the public can gamble on wars, or economic crises, or elections. That would destroy the very principle of representative government.” On March 25, Congresswoman Nikki Budzinski and Congressman Adrian Smith introduced the PREDICT Act in the House, which would extend restrictions to all members of Congress, the President, Vice President, and Executive Schedule appointees. Senator Kirsten Gillibrand’s broader bill would cast an even wider net across federal officials.
Political Candidates Caught Betting on Themselves
In April 2026, Kalshi suspended three political candidates for insider trading violations, exposing how the temptation to profit from privileged information extends beyond current officeholders. Mark Moran, a Virginia Senate candidate, wagered on his own election months before publicly declaring his candidacy—a clear case of exploiting non-public information for personal gain. Republican candidate Ezekiel Enriquez from Texas and an unnamed Minnesota congressional candidate also faced suspension. These enforcement actions demonstrate that prediction markets, while innovative financial instruments, create opportunities for corruption when participants possess material non-public information. Bobby DeNault, Kalshi’s Head of Enforcement, acknowledged the ongoing challenge: “Just like in traditional financial markets, bad actors will try to cheat on prediction markets.”
When Industries and Government Actually Agree
In a development that should raise eyebrows, major prediction market platforms enthusiastically support the proposed restrictions. Polymarket stated they are “in full support” of Senate legislation, while Kalshi called it “a great step to increase trust in our markets by making it an industry standard.” This alignment between industry and government is unusual but strategic—platforms recognize that insider trading scandals threaten their long-term credibility and could invite far more restrictive regulation. Both Kalshi and Polymarket have already implemented blocking mechanisms for members of Congress, moving ahead of legislation to demonstrate self-regulation capability. The question remains whether this cooperation reflects genuine commitment to market integrity or calculated damage control.
The Bigger Picture: Trust and Accountability
This legislative push exposes a fundamental problem that transcends partisan politics: government officials increasingly operate in financial gray areas that ordinary citizens cannot access. Prediction markets represent just the latest frontier where those with power and insider knowledge can enrich themselves while supposedly serving the public interest. The 2012 STOCK Act addressed congressional stock trading, yet loopholes persist and enforcement remains weak. While 70% of Americans support prediction market restrictions according to recent polling, public awareness of these platforms remains low. The real test will be whether Congress closes this loophole completely or leaves openings for future exploitation, and whether enforcement mechanisms have any teeth beyond symbolic gestures.
Members of Congress using online prediction markets? Don't bet on it

The House now faces pressure to match the Senate’s unanimous action and pass the PREDICT Act. Given bipartisan support and overwhelming public approval, passage appears likely. Yet citizens should remain skeptical about whether Washington will truly prevent its members from gambling with insider information, or simply create new workarounds that benefit the connected few while maintaining the appearance of reform. The prediction market scandal reveals a troubling reality: without constant vigilance, those entrusted with governing will find new ways to profit from their positions at the expense of the people they claim to serve.
