Polymarket and Kalshi are using local-news and sports-media affiliate pages to recruit sports traders during football season, with offers built around deposit bonuses, trading credits and reusable promo codes. An October 12 OregonLive page advertised Polymarket’s OREGON code as a $50 bonus after a $10 deposit, while SportsLine’s SPORTSLINE55 offer advertised $55 in Kalshi bonus trading credits after $25 in trades.
The marketing shift matters because the legal defense of event contracts rests on federal derivatives law, while much of the customer-acquisition copy now resembles online sports-betting promotion. The offers are not just a retail-growth tactic. They are also becoming evidence of how closely sports event contracts now compete for the same audience, publishers and game-week attention as sportsbooks.
What does the Polymarket OREGON code offer?
OregonLive’s October 12, 2026, listing said new users who registered with the Polymarket referral code OREGON and made a first deposit of $10 would receive a $50 bonus, for $60 in total trading funds. The page tied the code to NFL Week 4 markets and described it as available to new Polymarket U.S. accounts, according to OregonLive.
The same code appeared with different amounts on earlier OregonLive pages in October. An October 4 listing described OREGON as a $25 bonus after a $10 first deposit, according to OregonLive. An October 10 listing for USC-Penn State also described OREGON as a $25 bonus on a $10 deposit, according to OregonLive. By October 12, the OregonLive page for the same code advertised $50.
Other publishers have promoted different Polymarket codes and terms. RotoWire’s September 2026 ROTOWIRE listing advertised a $50 trading bonus after a $10 minimum deposit for new users, with 18-plus eligibility and one redemption per person, according to RotoWire. The spread of offers shows Polymarket using publisher-specific codes and changing promotional terms rather than relying on one uniform national offer.
How does Kalshi’s competing offer compare?
Kalshi’s sports-media offers have generally been structured around trading activity, not only a first deposit. SportsLine’s October 11, 2026, Kalshi promo-code page said SPORTSLINE55 gave new users $55 in bonus trading credits after their first $25 or more in trades, and described the code as active for that date, according to SportsLine.
Game-specific SportsLine pages have used the same basic format. A September 28 Bears-Eagles listing said SPORTSLINE55 gave new users $55 in bonus trading credits after $25 in trades, according to SportsLine. A September 27 Broncos-Rams page advertised SPORTSLINE as a $25 bonus after $25 in trades, according to SportsLine.
The distinction is material. A deposit-triggered promotion pays after the user funds an account. A trade-triggered promotion requires the user to put money through contracts first. In both cases, the publisher page follows a familiar sportsbook affiliate formula: matchup framing, a code, a bonus amount, eligibility language and a link that may compensate the publisher if the reader signs up or trades.
Why are prediction markets leaning into sports promotions?
Sports has become a major growth category for the largest prediction-market platforms. Pew Research Center found that combined monthly global trading volume on Kalshi and Polymarket rose from $26 billion in May 2026 to $53 billion in July 2026, based on The Block data, and said the increase was mostly driven by sports trading. Pew also reported that sports trading in June and July topped $58 billion on Kalshi and neared $22 billion on Polymarket, according to Pew Research Center.
Polymarket’s U.S. rollout also centered heavily on sports. Covers reported on May 12, 2026, that Polymarket was rolling out its U.S. exchange to iOS users after a waitlist period and that opening the app showed sports markets with trading prices. The same report cited more than 1.4 million waitlisted customers and said Polymarket U.S. had reached about $60 million in all-sports trading volume during early March Madness rounds and more than $90 million during the 2026 Masters, according to Covers.
Polymarket’s U.S. path follows a regulatory reset. The CFTC announced on January 3, 2022, that Blockratize Inc., doing business as Polymarket.com, agreed to pay a $1.4 million civil monetary penalty in an enforcement action over event-based binary options, according to the CFTC. Polymarket later announced on July 21, 2025, that it had acquired QCEX, including CFTC-licensed QCX LLC and QC Clearing LLC, for $112 million, according to the company’s acquisition announcement.
The product line has also moved toward more sportsbook-like sports structures. QCEX filed Polymarket U.S. Combinatorial Athletic Outcome Contracts with the CFTC on May 20, 2026, and the CFTC’s product-filing database lists the product as a certified binary-option swap in the event category, according to the CFTC filing page. The public terms describe contracts whose underlying is the joint settlement amount of two or more underlying contracts, according to the QCEX product certification.
Where can users actually claim these offers?
Availability is not uniform across the country. RotoWire’s September ROTOWIRE page listed Polymarket availability as 48 states plus Washington, D.C., with Minnesota and Nevada excluded, according to RotoWire. Other Polymarket affiliate pages have listed different restricted-state sets, so readers should treat each offer’s state list as offer-specific rather than platform-wide.
Minnesota is a central test case. On July 27, 2026, U.S. District Judge Katherine Menendez granted preliminary injunction motions by the CFTC, Kalshi and Polymarket, blocking Minnesota from enforcing Minn. Stat. Section 609.7615, as amended by SF 3432, against entities registered as designated contract markets by the CFTC until a final merits decision is reached, according to the U.S. District Court order.
Menendez emphasized that the injunction was preliminary, not a final decision on the parties’ claims and defenses. That matters for affiliate marketing because a preliminary order can reduce immediate enforcement risk without settling the ultimate boundary between state gambling law and federally regulated event contracts.
Nevada is more restrictive. The Nevada Gaming Control Board’s public timeline says it sent Kalshi a cease-and-desist letter on March 4, 2025, filed state-court enforcement action against Kalshi on February 17, 2026, and obtained a temporary restraining order on March 20, 2026, barring Kalshi from offering prohibited event contracts. The same timeline says Nevada obtained state-court orders against Polymarket and Coinbase in 2026, according to the Nevada Gaming Control Board.
Why does the marketing matter to regulators?
The industry’s core legal argument is that event contracts traded on CFTC-regulated markets are derivatives subject to federal oversight, not state-regulated sports wagers. The CFTC has made that argument directly in state litigation. In an April 28, 2026, release announcing a lawsuit against Wisconsin, the agency said Congress assigned the CFTC exclusive jurisdiction over various derivative products, including event contracts traded on designated contract markets, according to the CFTC.
The affiliate copy points in a different direction for state officials. A reader arriving from a football article sees a code, a bonus, a matchup and a call to trade on the game. Risk disclosures may use derivatives language, but the commercial presentation sits beside sportsbook-style promotions and sports-prediction content. That resemblance does not decide the legal question, but it gives state regulators a practical argument: the products are being sold to the public in the same channels and cadence as sports betting.
That tension is likely to remain the pressure point. Kalshi and Polymarket can point to federal registration, CFTC product filings and court orders that protect at least some activity. States can point to consumer-protection, gambling and advertising laws, especially when the customer journey begins on pages that look familiar to anyone who has used a sportsbook promo code.
What is the next regulatory milestone?
The next milestone is the merits phase of the Minnesota litigation and the continuing state-by-state fight over whether sports event contracts on CFTC-regulated exchanges preempt state gambling enforcement. Menendez’s July 27 order preserves the status quo for CFTC-registered designated contract markets in Minnesota, but it does not end the case.
For the market, the commercial question is already visible. Sports contracts are producing large trading volumes, and publisher affiliate pages are giving Kalshi and Polymarket a direct route to football audiences. For regulators, the same pages sharpen the question that will define the sector’s next phase: whether a federally regulated event contract can be marketed like a sportsbook promotion without eventually being treated like one.
