The Golden Rat

What is The Golden Rat?

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 The Golden Rat

“One fact of financial life should never be forgotten. Wall Street–to use the term in its figurative sense–would like its customers to make money, but what truly causes its denizens’ juices to flow is feverish activity. At such times, whatever foolishness can be marketed will be vigorously marketed–not by everyone but always by someone,” Buffett warned.

Buffett was not always entirely anti-gambling. Before commercial sports betting expanded across the United States, he regularly offered $1 million annually to any Berkshire Hathaway employee who submitted a perfect NCAA March Madness men’s basketball bracket.

To date, no individual has ever recorded a verified perfect NCAA tournament bracket.

Maloney leads an association that features sportsbook powerhouses such as DraftKings, FanDuel, Fanatics and Bet365.

“We welcome efforts by leagues, players and regulators to build on that work and make clear that harassment has no place in sports,” Maloney told iGB.

The NFL referenced a comparable incarnation of the platform in a letter this summer to the US Commodity Futures Trading Commission on prediction markets. The league was one of several that submitted public comments to the CFTC in regards to the agency’s proposed rules on event contracts.
