A White House staffer has been accused of using inside knowledge of speeches to make nearly $100,000 on Kalshi.

A White House teleprompter operator is being investigated over allegedly using inside information to place bets and make nearly $100,000 on US President Donald Trump's speeches. Gabriel Perez, who had worked at the White House since 2016, is accused of placing bets on words the president would use during major public addresses, including the State of the Union speech. The trades were made on Kalshi, a prediction markets platform where users can bet on real-world events. The firm confirmed it reported the activity to the Commodity Futures Trading Commission (CFTC), which regulates the platform. Kalshi froze Perez's account before any profits could be withdrawn, according to reports. The platform told the BBC its analysts noticed unusual betting on "mention markets" - contracts where users predict whether a speaker will use common terms, such as specific countries, economic words, or campaign slogans, in March. "The words of political leaders like Presidents and Fed chairs cause billions of dollars of movement in FX markets, oil futures, [and] the stock market," Kalshi said. Using account data, the company found the user was a federal employee operating White House teleprompters. Robert DeNault, Kalshi's head of enforcement, said the firm flagged the trades and had handed evidence to regulators.
