Trophy Fish

About Trophy Fish

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.

Japan has drawn on Singapore’s IR development model, which embodies a balancing act between ambitious economic visions and restrictive conditions. But Andrew Klebanow, principal of Klebanow Consulting, believes Japan’s IR regulations swerved “too far into crafting regulations and policies”. Klebanow specialises in hotel-casino market feasibility studies, strategic planning and facility planning recommendations.

“As the RFP process played out, regulators introduced additional policies and regulations. As each regulation was introduced, developers adjusted their gaming forecasting models downward. Finally, those models reached a tipping point where potential revenues were insufficient to justify a project’s capital costs,” says Klebanow.

Japan’s attempt to reap the economic benefits of casino gaming while keeping gambling socially contained is comparable to Asia’s dominant casino hubs Singapore and Macau.

Potentially boding well for the Macquarie forecast are at least two factors. First, there are signs of turnover increases across a variety of yes/no exchanges. Second, volume surged to start September with those spikes arriving even before the NFL season kicked off.

As Macquarie analyst Chad Beynon points out, prediction markets generated $4.3 billion in taker volume during the first week of September without any help from the NFL, building on momentum from the 2026 World Cup. However, the NFL’s impact was immediate, with taker volume hitting a daily record during Week 1 of the campaign.

With all that in mind, it’s not surprising that Macquarie expects sports event contracts will drive approximately 80% of taker volume this year, but Beynon sees other categories growing over the long term.
