What is Hot 81?
The Office of Information and Regulatory Affairs (OIRA) received the filing on September 17, which is titled “Regulation Crypto Asset Transactions and Regulation Crypto Asset Markets.” The proposal remains in the early stages, and the details are not yet public, as reported by The Block.
The move came shortly after the Senate declined to advance the Digital Asset Market CLARITY Act. The procedural vote on September 15 rejected it with 49-50, not meeting the 60 votes required to move forward.
The CFTC’s move gives the agency a chance to pursue parts of a crypto market framework under its existing authority, rather than waiting for Congress to resolve the broader legislative debate.
How to play Hot 81
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 Hot 81
The sanctions, effective from 28 August 2026 , bar Santos from any direct or indirect trading access on Kalshi.
Earlier this year, fellow prediction market platform Polymarket also ended its paid relationship with Santos amid a Department of Justice investigation over whether he had placed a wager on his appearance at the same State of Union address.
A federal judge sentenced Santos to 87 months in prison last April on felony wire fraud and check fraud charges. After Santos served several months in 2025, US President Donald Trump granted the former congressman clemency, resulting in his immediate release.
