Fake election polls raise concerns over prediction market manipulation ahead of midterms

A student's fake polling experiment highlighted growing worries about misinformation and insider trading on political betting platforms like Kalshi and Polymarket.

The short version

  • Rahil Prakash, a 21-year-old, admitted to releasing fabricated election polls under the entity 'Median Strategies' as a social experiment, which were briefly cited by media outlets and public figures.
  • Investigative checks by Kalshi and Polymarket found no evidence that Prakash placed bets related to the fake polling data on their platforms.
  • Financial reform advocates and political strategists warn that prediction markets remain vulnerable to manipulation by partisan actors, insider trading, and ginned-up online campaigns.
  • Regulators and law enforcement have not formally commented on whether the fake polling incident warrants criminal investigation.
