White House Staff Cautioned Against Insider Betting on Prediction Markets

White House staff received a clear warning last month, instructing them against utilising privileged information to place wagers on prediction markets. This internal communication, initially brought to light by the Wall Street Journal, was dispatched on 24th March, shortly after US President Donald Trump announced a temporary halt to his proposed actions against Iranian power plants and energy infrastructure.

Ethical Concerns and Official Response

The directive directly addressed press reports that highlighted potential ethical breaches by government officials using non-public information for financial benefit on platforms such as Kalshi or Polymarket. White House spokesman Davis Ingle robustly refuted any suggestions of such activity without substantiation, labelling such reporting as “baseless and irresponsible”. Ingle emphasised that all federal employees are bound by government ethics guidelines that strictly prohibit the exploitation of insider information for personal financial advantage. He further asserted, “The only special interest that will ever guide President Trump is the best interest of the American people.”

Previous Controversies and Market Growth

Prediction markets have experienced a significant surge in popularity over the past year, now facilitating over $44 billion in trades. These platforms allow users to bet on a diverse array of outcomes, from sports results to central bank interest rate decisions and election outcomes. Polymarket, in particular, faced considerable scrutiny in January following a substantial payout of nearly half a million dollars to a gambler who correctly predicted the capture of Venezuelan president Nicolás Maduro just prior to its official announcement. The anonymity of the account, identifiable only by a blockchain identifier, fuelled concerns that the individual may have benefited from insider knowledge concerning the US military operation.
