Polymarket US logs record 74 million trades in October

Sports contracts and parlay-style products pushed the CFTC-regulated prediction market to its busiest month yet Polymarket US just had its busiest month on record. The platform processed more than 74 million trades in October, a 15% jump from the month before. The milestone matters because it arrives as regulated prediction markets compete for the same pool of US users. The short answer is sports. Polymarket US expanded its sports contracts, with NFL and college football leading the charge. The other ingredient was product design. In August 2026, the platform rolled out combo and parlay-style products.
