Licensing, taxation, age limits and responsible-gaming rules applied to sports wagering, and whether event contracts fall inside them.
CFTC issued an interim final rule on Oct. 9 excluding state- and tribal-licensed casino sportsbooks from the swap definition. A proposal published the same day would treat exchange-traded sports and politics event contracts as swaps, so federal treatment would follow the venue.
Reality
Kalshi set daily volume records of $3.91 billion and $3.96 billion on Oct. 10 and 11, with parlay combos about 70% of each day. Markets outside combos traded $1.11 billion and $1.21 billion but supplied only 13% and 22% of the week-over-week gain.
Reality
Thirty-nine states, D.C., 145 tribal nations, the NFL and Gary Gensler urged the Supreme Court to decide whether sports prediction contracts are swaps. Two of the three appeals courts to rule have called those contracts state-regulated gambling, so platforms on federal licenses still face two possible regulators.
Reality
Mike Selig's CFTC put one rule into force Friday and proposed another defining event contracts as swaps under its sole oversight, with 30 days for comment. States have won two of three federal appellate rulings so far, and the Supreme Court has been asked to settle the fight.

New Jersey's bid for Supreme Court review of a ruling that shields Kalshi's sports contracts from state gaming law won the NFL's backing in an October 8 brief. The league counts its games as $1.8 billion of $3.3 billion traded on prediction markets on the season's first Sunday, so a ruling would decide who regulates most of that money.
Reality
The NFL asked the Supreme Court to back New Jersey against Kalshi, saying NFL games drew $1.8 billion of the $3.3 billion traded on opening Sunday. A ruling for the states would put the contracts that made up most of that day's trading under state gambling law.

Kalshi paid Blanche Lincoln's firm $180,000 in 2024 to lobby on the event contracts she warned in 2010 could become a backdoor for sports gambling. Her firm now asks the CFTC to take sole charge of the sports contracts behind most of Kalshi's volume, while state regulators can quote her 2010 speech back at her.
Reality
Sixth Circuit judges let Ohio and Tennessee enforce gambling law against Kalshi's sports contracts, putting two of three appeals courts on the states' side. New Jersey's contrary ruling still stands, so the same federally registered contract now has a different legal status depending on the state.

Polymarket launched opt-in deposit limits, self-exclusion and mental-health referrals on September 30, six days after New York sued it over sports contracts. The tools come alongside its federal-court claim that commodity law overrides the state's gambling statutes.
Reality
The city's consumer protection claims name the brokers that distribute Kalshi's sports event contracts, not just the exchange. Distribution is now part of the legal exposure.
Reality
New York sued Polymarket U.S. on Thursday for triple its gains plus $100,000 per sports-wager offer, following actions against Kalshi, Coinbase and Gemini. The state's gambling test fits the event contract itself, so one ruling could reset what investors pay for every operator New York has pursued.

A unanimous panel decided that Kalshi's contracts on who wins a game are likely bets rather than swaps, which turns one federal registration back into a fifty-state licensing problem for the exchange.

Sports contracts run above 80% of a market that went from $2bn in August 2025 to $38.5bn. Whether the justices take New Jersey's petition this fall will decide which compliance bill the industry pays.
Reality
Fullstory says 35% of bettors it polled use sportsbooks less because of prediction markets, CFTC-regulated venues that pay no state betting tax. DraftKings and FanDuel grew on a similar carve-out until states rewrote gambling law after 2015, and Kalshi's Illinois suit now contests that route.
Reality
The June restraining order metered noncompliance at $120,000 a day; Judge Aquilina's September 1 replacement charges up to $500,000, and it now travels down the clearing chain to the brokers routing the orders.
Reality
The four-year price works out near $205,000 for every day it runs, all of it riding on a definitional fight MLB is not party to, and the exclusivity the league sold leaves it no second venue if the states prevail.
Reality
Connecticut wants Hartford and its own consumer protection statute; Kalshi wants the Commodity Exchange Act, and it removed the case within hours. One district judge has already rejected the preemption argument.

RSBIX LLC filed in September 2025 expecting clearance by March 2026. Approval may now land as late as Q3 2026, which is the most specific public read available on CFTC pacing.
