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.

However, LSR noted that traditional game outcomes are no longer reliable indicators of bookmaker profitability, largely due to the rapid growth of same-game parlays and player props.
In the Las Vegas-based Circa Survivor contest, which drew over 25,000 entries entering Week 1, more than 8,000 entries were eliminated in the opening slate—most knocked out when the 8.5-point favorite Chargers fell to the Cardinals. That upset served as a proxy for the wider market, ruining countess parlay tickets across major sportsbooks.
Looking ahead to Week 2, bettors continue to chase high-scoring games. At BetMGM, Overs represent three of the five most-bet game totals by ticket count: Vikings-Bears (Over 48), Saints-Ravens (Over 46), and Panthers-Falcons (Over 44).
