Kalshi and Polymarket are moving deeper into the sports-affiliate marketing lane long used by online sportsbooks. Promo-code pages from CBS Sports, FOX Sports, Covers, AL.com and Rocky Top Insider now place prediction-market sign-up offers in the same search-driven commercial environment that sportsbooks use to acquire funded customers before football season.

What offers are sports affiliates advertising?

The Polymarket offers are not uniform across publishers. CBS Sports describes the CBSSPORTS code as a $20 trading bonus after a $10 deposit for new Polymarket US users. FOX Sports lists a similar FOX code, with a $20 trading bonus after a $10 deposit and an affiliate disclosure saying FOX Sports may be compensated if a reader signs up or places a wager through the page.

Other sports publishers list larger Polymarket bonuses with higher deposits. Covers describes the COVERS code as a $50 trading bonus after a $20 deposit. Rocky Top Insider lists the ROCKY code as $50 in trading funds after a $20 first deposit. The pages use a familiar affiliate format: code, deposit threshold, eligibility language and a call to claim the offer.

Kalshi’s affiliate terms use a different bonus mechanic. AL.com describes the ALCOM code as an offer of up to $500 after a first $25 trade. The same page lists the payout distribution as 70% of participants receiving $15 in bonus trading credits, 24% receiving $35, 5% receiving $75, 0.65% receiving $100 and 0.35% receiving $500.

Rocky Top Insider describes Kalshi’s ROCKY code as a variable bonus from $15 to $500 after a user funds an account and trades at least $25 within 30 days of signing up. That structure gives the offer a large headline number while disclosing that the most common outcome is a smaller credit.

Why are prediction markets showing up beside sportsbook promos?

The immediate reason is distribution. Sports publishers already run pages built around search traffic, bonus-code comparisons and legally sensitive eligibility language. Adding Kalshi and Polymarket gives those publishers another product to place before readers who are already searching for odds, futures, props and sports-related promotions.

The placement does not mean the products are legally identical. Kalshi is listed by the Commodity Futures Trading Commission as a designated contract market, with the CFTC’s Kalshi filing showing designated status dated November 3, 2020. The CFTC’s designated contract market registry also lists QCX LLC d/b/a Polymarket US as designated, with a July 9, 2025 date and a note that QCX operates under the Polymarket US name.

Polymarket’s own U.S. documentation draws a distinction between its international product and its U.S. product. The Polymarket US documentation describes the international Polymarket product as crypto-based, while describing Polymarket US as a fiat-based, U.S.-regulated platform operating as a designated contract market and derivatives clearing organization under CFTC oversight. Its regulatory page similarly describes Polymarket US as a CFTC-regulated DCM.

That distinction matters because sports affiliate pages can flatten the consumer experience. A reader sees a code, a deposit requirement and a bonus. Regulators and operators see different legal regimes, including federally regulated event contracts on one side and state-regulated sports wagering on the other.

How do Kalshi and Polymarket bonuses differ?

Polymarket’s listed affiliate offers are deposit-linked and fixed in the way they are presented. CBS Sports and FOX Sports describe $20 trading bonuses after $10 deposits. Covers and Rocky Top Insider describe $50 bonuses after $20 deposits. The variation is in publisher code and bonus size, not in a randomized prize table.

Kalshi’s affiliate pages use a variable-credit structure. AL.com’s table shows that a qualifying user can receive $15, $35, $75, $100 or $500, with the $15 credit carrying the highest stated probability. Rocky Top Insider describes the ROCKY code as a bonus of up to $500 after a $25 qualifying trade within 30 days.

The comparison points to marketing convergence more than product convergence. Kalshi and Polymarket are not presenting identical sign-up economics. They are using the same kind of acquisition channel that sportsbooks have spent years developing: sports content, search traffic, publisher-specific codes and bonus offers tied to account funding or trading activity.

Where do state restrictions fit?

Geography is one of the clearest gaps between a national sports page and the actual availability of a promotion. CBS Sports says Polymarket US is available in most U.S. states but lists Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, New Jersey, Nevada and Ohio as restricted. FOX Sports lists the same set of states as unavailable for its FOX-code bonus.

Kalshi affiliate pages also include eligibility limits. AL.com says new customers must be at least 18 and located in a qualifying state at registration. New York Post affiliate pages for Kalshi have described the NYPMAX offer as unavailable in Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, Ohio and Washington, with a $25 qualifying-trade requirement for the up-to-$500 bonus.

Those restrictions are commercially important because affiliate publishers have an economic interest in conversions. Their pages are useful evidence of what consumers are being shown, but they are marketing pages, not neutral regulatory analysis. The reader-facing question is simple: which code applies, what transaction is required, what states are excluded and whether the bonus is fixed or variable.

What does this mean for sportsbooks?

The affiliate overlap shows that prediction-market operators are competing for some of the same sports audience that sportsbooks target. It does not resolve whether any specific event contract should be treated like a sportsbook wager under state law, and it does not end the broader fight over federal versus state authority. It does show that customer acquisition is moving into the same media channels.

That matters because affiliate distribution is one of the main ways online betting brands convert sports-news readership into funded accounts. A consumer comparing a sportsbook promotion with a Kalshi or Polymarket promotion is often evaluating the visible offer first: bonus size, code, deposit or trade requirement, state availability and perceived upside.

For event-contract exchanges, that channel can scale attention quickly. It also raises the stakes for disclosures. When prediction-market promos appear next to sportsbook-style offers, questions about eligibility, risk language, bonus presentation and state restrictions become harder to separate from the larger legal fight over sports event contracts.

What is the next milestone?

The next practical test is the NFL regular season. The NFL schedule lists Patriots at Seahawks for Wednesday, September 9, 2026, at 8:20 p.m. ET on NBC. The league said in a May schedule report that the season opens that night in Seattle, followed by a Rams-49ers game tied to the league’s Australia schedule.

Sportsbooks typically spend heavily around the start of football season, and affiliate publishers have reason to refresh high-intent promo pages before kickoff. For Kalshi and Polymarket, the signal to watch is whether publisher-specific codes, state disclosures and football-market language expand as the September 9 opener approaches.
