Insider trading has long run rampant on prediction markets like Kalshi and Polymarket. We’ve seen shady accounts profit from accurately predicting the US invasion of Venezuela, resulting in arrests, or correctly guess everything that was going to happen at this year’s Super Bowl half-time show.
Now, in a particularly egregious instance of the worrying trend, president Donald Trump’s longtime teleprompter operator made tens of thousands of dollars by betting on Kalshi what the president would say, sources familiar with the matter told ABC News.
According to the sources, federal investigators with the Commodity Futures Trading Commission are in settlement talks with Trump’s technical assistant, Gabriel Perez, over allegations that he used inside knowledge to win more than $100,000.
That’s despite Trump being well-known for going on lengthy, off-script tirades during his infamously incoherent speeches.
