A Trump teleprompter operator is said to have made Kalshi’s bet on his statements

President Donald Trump’s longtime teleprompter operator is being investigated by federal regulators over alleged bets he made on the Kalshi prediction marketplace related to statements made by Trump.

The user allegedly made more than $90,000 in profits from the trade, but most of that money was frozen by Kalshi after bets on the platform’s “Mentions” market were flagged as suspicious, according to the company.

A person familiar with the Commodity Futures Trading Commission’s investigation, who spoke on condition of anonymity, identified the operator as Gabriel Perez, who has operated teleprompters for Trump’s speeches since the 2016 presidential campaign.

“Our monitoring team immediately flagged and referred this trade to the CFTC after investigating the exchange,” said Robert DeNault, Kalshi’s head of law, in a statement to CNBC.

“We have been assisting regulators in this matter and provided the evidence we have collected as we do in any transfer,” said DeNault.

The CFTC declined to comment.

CNBC has requested comment from the White House.

According to Kalshi, the company’s monitoring in March flagged trading in contracts related to Trump’s public statements that did not follow normal buying and selling patterns.

Some of the trades are marked separately by market makers in so-called reporting channels.

Kalshi’s surveillance analysts used data collected during customer login and monitoring processes to determine whether the account holder worked for the federal government and the teleprompter operator, according to the company.

Kalshi then closed the account, keeping almost all the profits.

Perez’s investigation was first reported by ABC News.

Perez’s LinkedIn page identifies him as an employee of VIP Prompting, a company that has reportedly operated teleprompters in the White House since the 1960s.

A person who answered the phone at VIP Prompting on Thursday declined to comment.

Kalshi prohibits insider trading on its platforms, and has taken steps throughout 2026 to deal with speculators using sensitive, non-public information to trade on their markets.

The company recently introduced new requirements for traders in certain markets to post information about their employment status. Those changes were announced in June, and the Perez trade was reportedly finalized in March.

The CFTC’s investigation of Perez follows two major insider trading cases involving prediction market platforms.

In April, a US Army master sergeant was arrested on federal criminal charges in a case where prosecutors said he made lucrative trades in event contracts on the Polymarket platform related to the US military’s mission to arrest Venezuelan leader Nicolás Maduro.

Sergeant, Gannon Ken Van Dyke, was allegedly involved in planning and executing the successful raid. Van Dyke has been sued in a civil complaint by the CFTC over his alleged conduct.

In May, federal prosecutors indicted ua Google employee, Michele Spagnuolo, for fraud in connection with alleged Polymarket contractsy were based on internal company data related to Google’s “Year in Search” list.
