WSJ Investigation Says Polymarket Used Fake Bet Videos to Promote Prediction Markets

According to the report, more than 1,100 videos were reviewed.

Some videos also depicted creators celebrating winnings that the Journal said would not have occurred on real markets.

Polymarket said it is committed to maintaining accurate and transparent markets and announced plans to audit active promotional content.
