What is Bass Boss?
“Our work is not driven by opposition to the gambling industry or to legal, licensed operators. Quite the contrary.”
The focus is on identifying illegal and unregulated gambling sites, operators that offer gambling services without the necessary licence, as well as sites that misuse, copy, or falsely refer to other operators’ licences.
“You can try to stop gambling, but then you go onto foreign gambling sites and crypto casinos and they keep appearing,” Madsen says.

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.
