Polymarket US and Kalshi are pushing new-user offers through sports and local-news publisher pages during the NFL season, while federal courts remain divided over whether state gambling regulators can reach sports event contracts listed on federally regulated prediction-market venues. The offers look similar to sportsbook affiliate promotions, but the legal posture is different: the exchanges argue they operate under federal commodities law.
The business signal is straightforward. Prediction-market exchanges are using football inventory and publisher distribution to acquire retail users at the same moment courts are deciding how much room states have to treat those products as sports wagering. That makes the promotion pages more than marketing copy. Their fine print has become a live map of the regulatory fight.
What are Polymarket and Kalshi offering around NFL games?
Polymarket affiliate pages have advertised a “Deposit $10, Get $25” new-user offer. An October 8 RotoWire page for code “ROTOWIRE” described the promotion as available to new users 18 or older, with a $10 minimum deposit and a $25 reward after deposit. The same page listed availability as 48 states plus Washington, D.C., excluding Minnesota and Nevada.
Another RotoWire page published the same day for the Buccaneers-Cowboys Thursday Night Football game described the same $25 trading-credit offer but listed New York and Nevada as excluded states. The difference matters because state availability is not a minor marketing detail in this sector. It is one of the most visible ways exchanges and publishers translate unsettled legal risk into customer-facing terms.
The publisher-code model extends beyond a single outlet. Syracuse.com has promoted the Polymarket code “CUSE” around Sunday Night Football, and Sports Illustrated has used “SIBONUS” around Thursday Night Football. Those pages put Polymarket’s U.S. return in front of sports readers through the same media channels that have long carried sportsbook bonus pages.
Kalshi’s publisher offers use a higher headline number and a trading requirement. A Sports Betting Dime page for code “WTOP55,” published September 27, described a “Trade $25, get a $55 bonus” offer for new Kalshi customers with a first deposit of at least $10. The page said the offer was not available in Massachusetts, Michigan, Nevada and Washington, while its FAQ section used a broader list that also included Arizona, Illinois, Maryland, Montana and Ohio.
Why does Polymarket’s CFTC status matter?
Polymarket’s U.S. exchange operates through QCX LLC, doing business as Polymarket US. In a signed amended order dated November 24, 2025, the Commodity Futures Trading Commission said QCX had been designated as a contract market on July 9, 2025, and vacated a prior restriction that barred futures commission merchants from intermediating transactions or carrying customer accounts for trades on the exchange.
The CFTC order did not bless any particular football promotion. It did, however, establish the regulatory framework Polymarket US relies on for intermediated access. The order said the exchange represented that it had developed surveillance systems, policies and procedures for an intermediated trading platform, and that it would remain subject to Commodity Exchange Act and CFTC rules applicable to designated contract markets.
That distinction is central to the industry’s legal argument. A sportsbook generally seeks state-by-state gaming approval. A designated contract market points to federal commodities law, CFTC oversight and the Commodity Exchange Act’s jurisdictional provisions. State regulators have answered that sports outcome contracts function as sports wagering when marketed and used around games.
What did the Illinois court actually decide?
On October 2, 2026, U.S. District Judge Martha M. Pacold in the Northern District of Illinois granted in part preliminary-injunction requests in consolidated litigation involving Coinbase Financial Markets, the United States, the CFTC, Kalshi and Illinois officials. The order was not a blanket ruling on every sports contract. It addressed representative title contracts sold by Kalshi, such as whether the Chicago Cubs would win the 2026 World Series.
Judge Pacold wrote that Kalshi’s title contracts likely qualified as swaps under the Commodity Exchange Act because they tied payment to an event or contingency associated with potential financial, economic or commercial consequences. On that basis, she found the plaintiffs were likely to show that parts of Illinois law were preempted when applied to those contracts traded on Kalshi’s designated contract market.
The order also described Coinbase’s role more narrowly than an exchange listing its own sports contracts. The court said Coinbase offers a virtual wallet and partnered with Kalshi so Coinbase users could buy and sell contracts listed on Kalshi’s platform with cryptocurrency held through Coinbase. That matters because the Illinois case turned on Kalshi-listed contracts and access to them, not a separate Coinbase sports-contract exchange.
Illinois’ fee provisions remain an important loose end. The court described state budget amendments imposing a 1.75% fee on a prediction market or exchange’s first five million “exchange wagers” tied to sporting contests or events, and a 3.5% fee after that. Judge Pacold continued part of the motions as to some issues, leaving the fee question and related state-law arguments for further proceedings.
Where do the appeals courts stand on state regulation?
The appellate picture is split. In KalshiEX LLC v. Assad, decided August 28, 2026, the Ninth Circuit affirmed in part an order dissolving an injunction against Nevada gaming officials as to Kalshi’s sports-related event contracts. The panel rejected Kalshi’s broad reading of the Commodity Exchange Act and allowed Nevada’s enforcement position to proceed at the preliminary-injunction stage.
The Sixth Circuit reached a similar result for Ohio and Tennessee on September 25, 2026, in KalshiEX LLC v. Schuler. The court affirmed denial of a preliminary injunction in Ohio, vacated an injunction Kalshi had won in Tennessee and remanded. The panel held that Kalshi had not shown its sports-event contracts satisfied the statutory definition of swaps for purposes of CFTC exclusive jurisdiction, and also rejected Kalshi’s preemption arguments at that stage.
The Third Circuit went the other way earlier in 2026 in the New Jersey litigation, a split now sitting in front of the Supreme Court. New Jersey has petitioned for review, and the NFL filed an amicus brief urging the justices to take the case. The core question is whether federal commodities law preempts state gambling law for sports event contracts listed on a CFTC-regulated designated contract market.
Why do the publisher codes matter for regulators?
The offers show how quickly prediction-market operators are moving toward a mass-market sports audience. A new user seeing “Deposit $10, Get $25” or “Trade $25, Get $55” beside NFL game copy is encountering the product in a context that looks familiar from sportsbook advertising, even if the legal wrapper is a federally regulated exchange rather than a state-licensed book.
That cuts both ways. For the exchanges, publisher distribution helps explain sports event contracts as tradable market instruments with user-set prices and no house-set odds. For state regulators, the same pages support the argument that these products are being sold to sports bettors around specific games, with bonuses, promo codes and eligibility language that closely resemble online wagering campaigns.
The next milestone is legal rather than promotional. Kalshi’s response to New Jersey’s Supreme Court petition is due November 9, 2026, according to the Supreme Court docket materials cited in public reporting. Until the justices act, or the CFTC completes further rulemaking on event contracts, state availability language on publisher pages will remain one of the clearest public signs of how each exchange is managing the unsettled map.
