Gabriel Perez, Donald Trump’s teleprompter operator, no longer works for the U.S. federal government. He was accused of using confidential information to bet on the president’s speeches via the Kalshi platform. His suspicious earnings reportedly exceed $100,000. Predictive markets like Kalshi rely on a simple principle: any citizen can bet on the outcome of a future event, from a political decision to a sports result. However, this promise of openness hits a red line: insider information. The platform has just demonstrated this by detecting Gabriel Perez’s suspicious transactions through its internal monitoring algorithms.
