The FBI went to the house of a man who runs a website called Polymarket, where people can bet on things.
Some people think the FBI went to the house because the website correctly guessed who would win the election.
But a smart investor named Kevin O'Leary said the FBI is just checking to make sure the website followed the rules about betting.
He told the man who runs the website to talk to a lawyer and be honest with the FBI so everything is okay.
