Two United States senators have called for a federal investigation into Polymarket, a prediction market platform, due to allegations of deceptive advertising. The senators specifically cited the platform's promotion of "fake bets" as a concern, following reporting by The Wall Street Journal.

The request directs federal regulators to examine Polymarket's advertising strategies and practices. The senators expressed alarm over promotions that they believe mislead consumers about the nature of the bets offered on the platform. The details of the specific advertising campaigns under scrutiny were not immediately available but are understood to be linked to the Journal's recent reporting on the company.

Polymarket operates as a platform where users can bet on the outcomes of future events, ranging from political elections to cryptocurrency price movements. Critics argue that the promotion of certain bets, particularly those with outcomes that are predetermined or manipulated, constitutes deceptive advertising and potentially violates federal regulations.
