Prediction Market Report Shows $11B-$34B Offshore US User Activity
A new report reveals that U.S. users drove $11 billion to $34 billion in offshore prediction market volume, with Polymarket accounting for up to $27 billion of that activity. The findings highlight the regulatory arbitrage driving American traders to unregulated platforms, though offshore market share declined from 84.4% in 2024 to 60.9% in 2025 as domestic alternatives like Kalshi gain traction.
