Kalshi is investigating three wagers placed shortly before Katie Zacharia was named White House press secretary on Oct. 9, 2026, after her odds on the platform had stood at approximately 1%, according to The Wall Street Journal. The bets totaled less than $175 but carried potential combined payouts of more than $9,500. A $19 wager placed late on Oct. 8 could return $1,896, while bets of about $74 and $80 placed minutes before the announcement could return $3,689 and $4,023. Zacharia's appointment was disclosed in a post on Truth Social. Kalshi confirmed the investigation and said it was part of efforts to protect market integrity, but has not identified the traders or said whether payouts were held back. The case follows similar scrutiny involving the platform, including a July 2026 CFTC probe into trades tied to the content of Trump's speeches by his teleprompter operator, whose profits were frozen.
