Summary
-
Kalshi is investigating suspicious wagers that correctly predicted Katie Zacharia’s appointment as White House press secretary before public confirmation emerged.
-
Three wagers involving relatively small investments could generate substantial payouts, raising concerns about potential misuse of confidential government appointment information.
-
Previous insider trading cases prompted Kalshi to strengthen disclosure requirements, while congressional investigators examined safeguards against suspicious prediction market activity.
Prediction market platform Kalshi has launched an investigation into unusually profitable wagers linked to President Donald Trump’s latest White House appointment. Several traders correctly backed Katie Zacharia before news outlets revealed her selection as the next White House press secretary.
According to The Wall Street Journal, Kalshi confirmed the investigation but declined to provide details about the traders involved. The platform keeps traders’ identities confidential from the public while maintaining internal records for compliance purposes.
The investigation centers on three wagers placed before media reports identified Zacharia as Karoline Leavitt’s successor. Public trading records show that the bets could generate substantial returns despite involving relatively small investments.
One trader placed a $19 wager Thursday evening, which could return $1,896 when the market settles. Two additional wagers worth approximately $74 and $80 could generate payouts of $3,689 and $4,023, respectively. Notably, Kalshi traders had assigned Zacharia approximately 1% odds of securing the position before the appointment became public.
Trump subsequently confirmed Zacharia’s appointment through Truth Social, expressing confidence in her ability to serve the administration. Zacharia previously worked at the Department of Homeland Security and serves as a senior communications adviser at Trump Media.

The investigation adds to regulatory concerns surrounding traders who may exploit confidential government information for financial advantage. In August, former White House teleprompter operator Gabriel Perez settled Commodity Futures Trading Commission charges involving trades linked to Trump’s prepared remarks. Perez agreed to repay $107,539 in profits and pay a $65,000 civil penalty.
Additionally, Kalshi permanently banned former Representative George Santos over wagers connected to his State of the Union attendance. The platform also imposed a financial penalty exceeding $71,000. These enforcement actions followed increased scrutiny of prediction markets and their safeguards against trading based on confidential information.
In June, Kalshi introduced employer disclosure requirements for participants trading in markets carrying heightened insider trading risks. The company reported opening more than 150 investigations and making over 20 law enforcement referrals during the first quarter.
Meanwhile, House Oversight Committee Chairman James Comer launched a congressional investigation into insider trading safeguards at Kalshi and Polymarket.
The committee requested information about identity verification procedures and systems designed to identify suspicious trading patterns. Kalshi’s latest investigation remains unresolved, with no public findings establishing whether the Zacharia wagers involved improper access to confidential information.
