Kalshi investigates suspicious trades tied to Trump's press secretary pick

Prediction market platform Kalshi is investigating three suspicious trades placed shortly before U.S. President Donald Trump appointed conservative commentator Katie Zacharia as White House press secretary on October 9, 2026. The wagers, totaling under $175, yielded potential payouts over $9,500 after Zacharia's odds shifted from 1%. The probe highlights ongoing scrutiny over insider trading risks on prediction platforms, following a similar July 2026 CFTC investigation into Trump's teleprompter operator.
