Oct 9 (Reuters) – Prediction market Kalshi has launched an investigation into suspicious trades tied to the selection of ​Katie Zacharia as U.S. President ‌Donald Trump’s new White House press secretary, the Wall Street Journal reported on Friday, citing a company spokesperson.

Kalshi declined to comment on ‌the ​report.

Here are some details:

• ⁠At least three ⁠small wagers were placed before news of Zacharia’s selection emerged, potentially netting traders thousands of dollars in profits, the ​Journal reported.

• A $19 bet placed late on Thursday is set to pay $1,896, ⁠while wagers of about $74 ⁠and $80 placed on Friday are ​expected to pay $3,689 and $4,023, respectively.

• Zacharia, a ​conservative commentator who previously worked briefly ‌at the Department of Homeland Security, had been given about a 1% chance of securing the role on Kalshi ⁠before the announcement.

• Prediction markets, where users wager on outcomes ranging from sporting contests to ⁠world events, ‌have faced growing scrutiny over ⁠the risk of traders profiting ​from ‌inside information.

• In July, Trump’s ​teleprompter operator ⁠came under investigation by the U.S. Commodity Futures Trading Commission over potential insider trading.
