Before Patrick Mahomes laced up his cleats for his 2026-2027 NFL regular-season debut, US prediction markets had already cleared a historic benchmark for the opening week of the season.
Two operators alone – Kalshi and Polymarket – topped the combined $1 billion mark in NFL trading activity over the first six days of Week 1, according to numerous measures this week. During the period, Kalshi recorded NFL volume of $983.4 million, according to DeFi Rate, earning the pole position by a large margin. Mahomes and the Kansas City Chiefs thrashed the Denver Broncos 31-10 on Monday Night Football, capping the largest week for prediction markets ever.
Even before the primetime matchup in Kansas City, it became abundantly clear that the industry would shatter previous marks for weekly activity. The AFC West showdown bolstered the already robust totals. Overall, volume for the week hit a record $15.9 billion, according to Bank of America, up 16% from a week earlier.

The report underscored gambling harm as a significant public health concern. It cited the Gambling Commission’s Gambling Survey for Great Britain (GSGB), which has indicated that between one and 1.5 million adults in Great Britain now score high enough on the Problem Gambling Severity Index (PGSI) rangeto indicate problem gambling.
According to the system used to rank players on the PGSI, a score of 0 or between 1 and 3 is considered low-risk, while scoring between 3 and 7 suggests moderate risk, and a score of 8 or higher represents problem gambling.
Although many industry commentators have pushed back against the GSGB and methods used in the survey to determine the scale of problem gambling in the UK.
