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 pure-play prediction market-operators, Polymarket and Kalshi, emerged from Week 1 as the clear winners. On one hand, Kalshi’s market share lead narrowed over its competitors, falling to 82% for the week ended 13 September, down from 86% a week earlier.

Brazil’s President Luiz Inácio Lula da Silva is expected to send a provisional measure to Congress this week to tighten the regulations for betting in Brazil.
According to CNN Brazil, the government is considering expanding restrictions on betting advertising and banning online casino games. The idea would be to maintain only sports betting.
The decision to use a provisional measure means the restrictions can take effect immediately, less than a month before the elections. This is the clearest indication yet that the sector is being used for electoral purposes to try and secure Lula’s re-election.
