WSJ reports Polymarket has a lucrative deal with streamer Adin Ross. In at least 5 videos, Ross showed ways to use inside info to trade, the Journal found.

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

Polymarket allegedly paid creators to produce misleading videos showcasing fake bets and winnings, amplified by a social-media campaign orchestrated by a marketing contractor.
