A recent Wall Street Journal investigation found that the prediction market hired influencers to stage fake trades as part of its marketing campaign to attract U.S. users.

Many of those videos were reportedly filmed on “near-perfect copies” of the Polymarket website, while featuring trades and winnings that were not real.

The Journal reviewed more than 1,100 videos and found none of the roughly $1.9 million in bets shown in influencer-produced hype videos were real.
