Reports say Gabriel Perez, a White House aide responsible for teleprompter content, made about $100,000 by trading on Kalshi contracts predicting words or phrases in President Trump’s speeches. The allegations raise concerns that people with access to non-public government information may profit from prediction markets, despite White House guidance telling staff not to use such information to trade contracts.

According to NPR and ABC sources cited by Ars Technica, Perez allegedly placed the trades over several months around the end of last year and start of this year, while having final review of many prepared presidential remarks and receiving last-minute edits. Investigators reportedly found instances where bets were adjusted during speeches when Trump skipped passages containing words Perez had backed; Kalshi, which prohibits such conduct, flagged the activity and investigated it.
