Coplan, Polymarket's 26-year-old founder, was roused from his bed at 6 a.m. by FBI agents demanding he give them his electronic devices.
The DOJ is investigating Polymarket for allegedly allowing U.S.-based users to bet on the site, Bloomberg News reported Wednesday evening.
Polymarket declined to comment on those allegations but a spokesperson said the FBI raid was "obvious political retribution by the outgoing administration against Polymarket for providing a market that correctly called the 2024 presidential election."

Polymarket, which does not allow trading in the U.S., also gained scrutiny after a mystery French trader, known as the Polymarket whale, made large bets on Trump winning the election.
The trader's huge wagers came in tandem with a dramatic rise in Trump's chances on the exchanges.
He walked away with more than $46 million in profit.
Last week, France's gambling regulator said it was examining whether Polymarket complies with French laws.
