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.
What is Deep Descent?
Not a single newspaper reference to Naked City appears in a Las Vegas newspaper before a June 20, 1982, Las Vegas Review-Journal cover story headlined: “’Naked City’ a Las Vegas Battleground.”
In that story, Lt. John Conner reported investigating 10 killings in the neighborhood in 16 months. “Most of them appear to be drug-related,” the homicide chief said.
The Meadows Addition—”Las Vegas” is Spanish for “the meadows”—was created in the late 1940s as a grid of 16 streets named after other cities, including New York, Chicago, Cleveland, St. Louis, and Philadelphia. Before the Sahara opened in 1952, Sahara Avenue was wholly contained in this community, where it was known as San Francisco Street.
About Deep Descent
– In the wake of a consequential ruling by the US Court of Appeals for the Ninth Circuit against Kalshi, two operators are taking separate paths in an effort to overturn the decision. On 28 August, the Ninth Circuit ruled in a 3-0 decision that sports event contracts do not qualify as federally regulated swaps under the Commodity Exchange Act. Earlier this week, Kalshi filed for an en banc re-hearing with the Ninth Circuit, this time before an 11-judge review. Robinhood, meanwhile, filed a petition of certiorari with the Supreme Court in a move to effectively bypass the Ninth Circuit. It is widely believed that a circuit split between the Ninth Circuit and a separate decision by the Third Circuit will prompt the Supreme Court to take up the case.
– Real App, a social sports app built around live play-by-play, named FanDuel as its first prediction market partner. The partnership brings FanDuel’s odds and contextual markets directly into the app’s live sports experience. Fanatics Sports & Casino is adding some upgrades to its Fair Play offering. Among the changes, Fanatics has added first-half injury protection for player props. The option proved to be valuable for fans in Wednesday’s opener when Seattle Seahawks quarterback Sam Darnold left the game after the team’s fifth offensive play.
– According to the American Gaming Association, an estimated $40 billion will be wagered on the NFL via prediction markets this year. Last week, on the first full day of the 2026 college football season, Kalshi reported nearly $250 million in trading activity on college football.
