Samurai Katsumi

What is Samurai Katsumi?

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.

About Samurai Katsumi

Prediction markets have proven effective at attracting sharp bettors and high-rollers who are often limited or banned by traditional sportsbooks. However, consumer surveys indicate that when given the choice between a sportsbook and a yes/no exchange, most recreational bettors still prefer the traditional sportsbook interface. That dynamic helps explain why prediction markets remain in second place.

“Prediction markets represent a meaningful second channel for NFL wagering but still small on a relative scale, reflecting a new sector with less of an installed base,” observes EKG.

It’s widely believed that all-or-nothing exchanges are carving out significant niches in states, such as California and Texas, where sports betting is prohibited, but there’s also emerging consensus that the prediction market threat to sportsbooks is easing.

About Samurai Katsumi

Akolade said the ARGN was established to address the fragmented nature of responsible gambling efforts across Africa and create a platform for greater collaboration between organisations working in the space.

“ARGN was created because problem gambling is becoming a bigger issue across Africa and most responsible gambling efforts still happen within individual countries,” Akolade tells iGB. “While many organisations are doing great work, there has been limited opportunity to learn from each other, share research, or work together on common challenges.

“We felt there was a gap for a continent-wide network that could connect organisations, encourage collaboration, and help build a stronger collective voice on player protection. ARGN is not here to replace national organisations or regulators. Its purpose is to support and strengthen the work already being done by bringing people and organisations together.”
