Crypto prediction markets are on the congressional chopping block after being flagged as national security risks. The push for a ban comes as Bubblemaps investigators led by Nicolas Vaiman uncovered 80 Polymarket bets with a 98% win rate — a pattern they say is statistically impossible to achieve by chance.
The Polymarket anomaly
Bubblemaps, a blockchain analytics firm, dug into Polymarket's activity and found something odd. A cluster of 80 accounts racked up wins at a rate that defies probability. Nicolas Vaiman, the lead investigator, said the numbers don't add up. The bets weren't just lucky — they were too consistent. While Bubblemaps didn't name who was behind them, the implication is clear: someone may have had inside information or manipulated the market. Polymarket hasn't commented publicly.
National security fears
Lawmakers on Capitol Hill are now treating these platforms as more than just gambling. They're calling them a national security vulnerability. The concern? Prediction markets can be used to bet on sensitive events — elections, geopolitical moves, even military operations. If bad actors can exploit them for profit or to signal intentions, the risk goes beyond financial loss. A congressional source told GFdaily that at least two committees are drafting legislation that would effectively ban crypto prediction markets in the U.S. The timing isn't great for Polymarket, which has been trying to position itself as a legitimate forecasting tool.
The ban isn't law yet. But the combination of the Bubblemaps findings and the national security label gives lawmakers ammunition. A bill could land on the floor as early as next month. For now, Polymarket users are left wondering if their positions will be wiped out by a government crackdown. The company hasn't said how it would respond to a ban, but legal challenges are likely. One thing is certain: the days of betting on elections with crypto are numbered.
