Polymarket vows insider trading crackdown as traders bet $12M on CLARITY Act
Polymarket says it is strengthening systems to identify insider trading and suspicious activity ahead of the US midterm elections. Traders have wagered $12 million on the CLARITY Act, highlighting the platform's growing role in political prediction markets. The company announced new measures to address misconduct concerns as election-related volume climbs toward November. The pledge follows a fast-rising enforcement bar across CFTC-regulated venues.
Kalshi's three recent bans on politically connected traders have set a new surveillance speed that Polymarket must now match. The CFTC fined a White House teleprompter operator $172,000 and Kalshi expelled George Santos and Laurie Buckhout before any regulatory filing. Those moves create a concrete template Washington will replicate. If Polymarket's midterm monitoring lags, regulators can treat it as the soft venue in the next insider-trading case.
Competitors without comparable detection records look negligent by comparison. Polymarket's 100-plus law enforcement case history is now a credential it must advertise loudly. The $12 million in CLARITY Act volume raises the stakes: more money on political contracts means more incentive for insiders to trade on advance knowledge. Whichever platform moves slowest becomes the natural target for the next CFTC action.
