Polymarket Accused of Faking Trading Volume to Lure U.S. Users

Key Facts

1A Wall Street Journal investigation revealed that Polymarket hired influencers to stage fake trades as part of a marketing campaign to attract U.S. users.

2A sports-betting attorney suggests that the chances of the Trump administration investigating these allegations are slim.

Amid intensifying regulatory scrutiny of crypto-based prediction markets, a Wall Street Journal investigation has revealed that Polymarket hired influencers to stage fake trades to attract U.S. users. According to reports, the platform allegedly used this marketing tactic to boost perceived liquidity and popularity despite legal restrictions barring U.S. residents from its services. However, a sports-betting attorney suggests that the likelihood of the Trump administration launching a formal probe into these allegations remains slim.

These allegations surface as prediction platforms face mounting pressure to verify authentic trading volumes and eliminate "wash trading" practices. In comparison, Kalshi, a regulated U.S. competitor, has seen a significant rise in legal trading volume over recent months per market data. Legal experts note that regulatory scrutiny typically intensifies when offshore platforms are found targeting protected U.S. consumers, potentially placing Polymarket in a precarious position regardless of the broader political climate.

Looking ahead, traders are monitoring for any official response from the DOJ or CFTC regarding these claims. On the macroeconomic front, market sentiment remains influenced by the Fed Interest Rate Decision on June 17, 2026, which held rates at 3.75%, impacting risk appetite across the digital asset sector. Investors should watch for further regulatory catalysts or updates regarding platform transparency that could impact the broader prediction market ecosystem.
