Regulated prediction market Kalshi is investigating three suspicious bets totaling $173 that accurately predicted President Donald Trump's selection of Katie Zacharia as White House Press Secretary minutes before media reports surfaced, positioning the trader to yield $9,608 in returns.
Suspicious Trading Timeline Ahead of Official Announcement
Prior to the trades, contracts on Kalshi—which is regulated by the Commodity Futures Trading Commission (CFTC)—assigned Zacharia roughly a 1% chance of being named press secretary. The first wager of $19 was executed at approximately 10:43 p.m. ET on Thursday, establishing a payout of $1,896.
On Friday at roughly 1:41 p.m. ET, two subsequent orders of $74 and $80 were placed, setting up payouts of $3,689 and $4,023, respectively. Approximately 20 minutes later, The New York Times and other outlets began reporting the pick, which Trump subsequently confirmed on Truth Social. Zacharia, an attorney, commentator on Fox News and Newsmax, and communications advisor to Trump Media & Technology Group, succeeds Karoline Leavitt in the role.
Key Takeaways
- Three bets totaling $173 were entered on Kalshi while Katie Zacharia stood at 1% odds, locking in $9,608 in prospective payouts.
- The final two trades occurred roughly 20 minutes before media outlets reported the official White House appointment.
- The investigation follows heightened regulatory scrutiny, including recent proposed CFTC prediction contract oversight across event derivative platforms.
Growing Scrutiny Over Nonpublic Information Leaks
Why it matters: The timing of these trades highlights ongoing vulnerabilities in prediction markets where nonpublic government developments can be monetized ahead of official disclosures. As regulated event contracts gain broader adoption, maintaining market integrity and curbing insider activity present persistent compliance challenges. Increased enforcement and stricter oversight from CFTC regulators are likely to follow as event markets expand.
This is not the first case involving political information on prediction venues. In August, Trump's teleprompter operator, Gabriel Perez, settled with the CFTC after trading on presidential speech topics, forfeiting $107,539, paying a $65,000 penalty, and taking a three-year trading ban. Additionally, early wagers related to the Iran war prompted a White House memo warning personnel against using nonpublic details for financial gain, while lawmakers launched an insider trading inquiry last month into three other platforms. Kalshi has not publicly disclosed potential outcomes of its ongoing review.
