How to play Mystery Museum

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.

Rashid received a 17‑month sentence following a hearing in U.S. District Court, where he admitted to a series of breaches that prosecutors said showed he had not reformed.

In 2021, Judge Gloria Navarro sentenced Rashid to 33 months at the Federal Correctional Institution in Sheridan, Ore., followed by three years of supervised release after he pleaded guilty to one count of using an interstate facility in aid of unlawful activity—specifically, a prostitution service.

According to the FBI, which raided his Las Vegas house on human trafficking warrants in 2014, Rashid “persuaded, induced, enticed and caused hundreds of victims to prostitute themselves for his benefit” beginning in 2002.
