Kalshi Reviews Well-Timed Bets on Trump’s Pick of House…
By Abdelaziz Fathi
AI summary of the source article
Kalshi is investigating three well-timed bets totaling about $173 on Donald Trump naming Katie Zacharia as White House press secretary, placed shortly before public reports of her appointment. Zacharia had traded at roughly a 1% probability, and the wagers stand to return approximately $9,608. While there is no public proof the traders possessed nonpublic information, the probe highlights integrity challenges in political event contracts. Kalshi has previously worked with the CFTC on insider cases, including one involving a former White House teleprompter operator, and has introduced employment verification, risk scoring, and surveillance tools with Nasdaq Market Surveillance.
