Overview
- An NPR investigation published Thursday detailed campaign aides who used unreleased polling to bet on their own races and pocket thousands of dollars.
- Staffers described a simple playbook: get a tip on a not-yet-public poll, compare it to odds on sites like PredictIt or Polymarket, buy low-priced event contracts, then sell after the poll’s release lifts the price.
- Experts told reporters the tactic may violate the Commodity Exchange Act when traders use material nonpublic information, while a former CFTC commissioner said the agency lacks tested tools to police election-related bets.
- Platforms and institutions have begun to respond, with Kalshi banning and fining political candidates found to have wagered on themselves, the Senate barring members and staff from betting, the White House warning employees, and some campaigns banning the apps.
- Event contracts trade in cents that mirror implied odds, so a 20-cent price reflects an estimated 20% chance of an outcome, which lets insiders with early data turn small, fast moves into outsized gains.
