Polymarket and Kalshi hit a record $44.8 billion in June volume on World Cup betting, while Bitcoin slid to $64,000. The CFTC comment period on a proposed rule closes July 27.
Polymarket and Kalshi hit a combined $44.8 billion in monthly trading volume in June 2026, driven largely by the FIFA World Cup. Bitcoin ($BTC) traded near $64,000, roughly 50% below its October 2025 peak of $126,000.
World Cup betting turned the two platforms into de facto global sportsbooks, according to Galaxy analysts. Those analysts had previously forecast weekly Polymarket volumes would surpass $1.5 billion in 2026. The June numbers surpassed those forecasts, the analysts noted. 21Shares projects annual prediction market volume will exceed $100 billion by year-end 2026.
Bitcoin's decline from its October highs has been gradual. Persistent inflation and economic uncertainty weighed on risk assets, traders said. Altcoins fell more sharply, they added. The broader crypto market analysis shows the total altcoin market cap contracting.
The CFTC proposed a rule in June 2026 on public interest determinations for prediction markets. The comment period runs to July 27, 2026.
