Kalshi probing suspicious trades on press secretary pick

Kalshi is investigating trading on its platform tied to the selection of Katie Zacharia as US President Donald Trump's new White House press secretary, according to the Wall Street Journal, as relayed by Devdiscourse.

The Wall Street Journal reported the inquiry on Friday, citing a Kalshi spokesperson. The investigation concerns a series of trades described as suspicious.

What is known—and what remains unclear

The supplied report identifies the appointment at the center of the inquiry but gives no details about the traders, the size of their positions or when the transactions occurred.

It also provides no findings from the investigation or explanation of what prompted scrutiny. The reported inquiry does not, by itself, establish that any trader engaged in misconduct.

What it means for prediction markets

• An appointment market is under scrutiny: The investigation concerns trading tied specifically to Zacharia's selection as White House press secretary.
• Key trading details remain unavailable: Without transaction timing, position sizes or information about the accounts involved, the supplied report offers little basis for assessing the suspicious activity.
• The outcome remains unresolved: The report establishes that Kalshi is investigating, not that it has reached a conclusion about the trades.
