U.S. users contribute $110 billion to $340 billion in offshore prediction market volume, report shows

According to a report by consulting firm Crane Zeng, U.S. users' trading volume on offshore prediction markets ranges from $11 billion to $34 billion, accounting for 12.5% to 31.5% of total U.S. prediction market volume. Of this, the single platform Polymarket contributed $11 billion to $27 billion in trading volume. The report forecasts that by 2030, annual trading volume by U.S. users on offshore prediction markets will reach $133 billion. Prediction markets have experienced rapid growth over the past two years, with Kalshi and Polymarket as key representatives. The U.S. CFTC has adopted a more relaxed stance toward domestic prediction markets, but unlicensed offshore platforms are prohibited from serving U.S. customers. Polymarket was banned from operating in the U.S. in 2022 for providing unregistered services to U.S. clients.
