Affiliate licensing requirements for US sports betting now diverge so sharply by state that the same marketing business can run registration-free in Ohio while facing a supplier-level background check three states away in Michigan. At least eight states, including New Jersey, Pennsylvania, Michigan, Louisiana, Indiana, Virginia and Colorado, require affiliates to register or hold a license before they can send traffic to a licensed sportsbook. Ohio, one of the newest markets, asks affiliates to register nothing at all.
For anyone building or scaling an affiliate business in US sports betting, that patchwork is not a footnote. It decides how fast a new state launch can be monetized, what a compliance team costs, and which commission model an affiliate can realistically run in a given jurisdiction.
The commission model decides the licensing tier
Every state that regulates affiliates draws the same underlying line: how the affiliate gets paid determines how hard it is scrutinized.
An affiliate paid a flat fee or a cost-per-acquisition (CPA) rate for each new depositing customer is, in most states, treated as a lower-risk vendor. An affiliate paid on revenue share, meaning it earns a cut of what the players it refers lose over time, is treated closer to an operator itself, because its income now depends on player losses rather than a one-time signup.
Michigan states this distinction directly. Under the Michigan Gaming Control Board's framework, an affiliate marketer with an agreement based on sharing customer revenue must be licensed as a supplier, while an affiliate marketer without a revenue-sharing agreement can instead register as a vendor, a lighter process required of any vendor supplying more than $100,000 worth of goods or services to a sports betting operator or platform provider in a year.
New Jersey's Division of Gaming Enforcement (DGE) draws an almost identical line. An affiliate compensated by cost-per-click, cost-per-impression, or a flat-fee sponsorship deal needs only a vendor registration, a form the casino itself files with DGE on the affiliate's behalf. An affiliate paid on deposits, total bets placed, or any revenue-share arrangement needs an Ancillary Casino Service Industry Enterprise (CSIE) license instead, a materially heavier filing, according to gaming law firm Ifrah Law.
Colorado's Division of Gaming runs the same split through its vendor tiers: a marketing affiliate on a flat fee typically qualifies for a Vendor Minor license, while a revenue-share arrangement pushes the affiliate toward the more demanding Vendor Major category.
That tiering has a direct commercial consequence, one that connects to the industry's broader shift from CPA deals toward revenue share: a network chasing recurring revenue-share income in a state like Michigan or Colorado is also signing up for the state's heaviest compliance track, not just a different payout curve.
How affiliate licensing works, state by state
The specifics vary enough that a compliance plan built for one state rarely transfers cleanly to the next.
Pennsylvania treats all gaming affiliates as Gaming Service Providers under the Pennsylvania Gaming Control Board, but splits them into two license classes. A flat-fee affiliate applies for registration: a $500 entity fee, $60 per qualifier, $60 per affiliated entity, and a $2,500 license fee over a five-year term. A revenue-share affiliate needs certification: a $2,500 entity fee, $500 per affiliated entity, $1,000 per qualifier, and a $5,000 five-year license fee, plus personal history disclosures for owners and officers involved in soliciting business, according to Ifrah Law's review of the Board's rules.
Louisiana folds affiliates into its non-gaming supplier permit system. Louisiana Administrative Code title 42, §III-2108 requires a non-gaming supplier permit before any entity supplies goods or services worth $500,000 or more to a licensee or casino operator in a calendar year, a threshold that trade press covering Louisiana's market has reported applies to affiliate marketers operating at scale in the state.
Indiana requires affiliates that promote and direct traffic to a sportsbook in exchange for commission to register with the Indiana Gaming Commission as a sports wagering registrant, a $500 nonrefundable application fee plus a criminal background check, under the Commission's sports wagering rules. Larger or revenue-linked arrangements can instead fall under the Commission's supplier or service-provider license categories, which carry a heavier review.
Virginia defines a "marketing affiliate" separately from a supplier under its sports betting regulations (11VAC5-70-10), and requires anyone acting as a sports betting vendor, including affiliates, to hold a Sports Betting Vendor Registration before performing vendor functions for a permit holder, per the Virginia Administrative Code.
Colorado's Division of Gaming has issued Vendor Minor licenses to marketing-focused affiliates for years. Media Troopers, a sports betting and iGaming marketing agency, had its Colorado vendor license renewed for a further two years in early 2025, the company's continuation as a licensed vendor since it entered the state, according to Gambling Insider.
Beyond the seven states detailed above, compliance advisory firm Clearsky Network counts thirteen states in total that require some form of affiliate licensing, adding Arizona, Maine, Maryland, Massachusetts, Tennessee and West Virginia, each with its own application and fee schedule and the same revenue-share-versus-CPA split found in Michigan, New Jersey, Pennsylvania and Colorado.
The table below lines up how the states that regulate affiliates split the two payment models.
| State | Affiliate licensing required | Flat fee / CPA affiliate | Revenue-share affiliate |
|---|---|---|---|
| New Jersey | Yes | Vendor Registration Form | Ancillary CSIE license |
| Pennsylvania | Yes | Registered Gaming Service Provider | Certified Gaming Service Provider |
| Michigan | Yes | Vendor registration (over $100,000/yr) | Full supplier license |
| Louisiana | Yes | Non-gaming supplier permit above $500,000/yr | Same threshold |
| Indiana | Yes | Sports wagering registrant ($500 fee) | Supplier / service-provider license |
| Virginia | Yes | Sports Betting Vendor Registration | Same registration, heavier review |
| Colorado | Yes | Vendor Minor license | Vendor Major license |
| Ohio | No | No registration | No registration |
Ohio and the states that ask for nothing
Ohio is the clearest counterexample. Under Ohio Administrative Code 3775-16-08, no affiliate marketer is required to be licensed, and the Ohio Casino Control Commission does not exercise direct licensing authority over affiliates at all.
The obligation instead sits with the operator. A sports gaming proprietor or service provider must ensure that any affiliate marketing on its behalf follows the Commission's advertising standards, and a violation by the affiliate can be held against the operator, up to termination of the marketing relationship, under the same rule.
That model shifts the compliance burden from the affiliate to its operator partners, which is a materially cheaper way to enter a state, but it also means an Ohio-only affiliate has no state-issued credential to show a prospective operator partner, unlike an affiliate that can point to an active Michigan or New Jersey registration as a mark of good standing.
What multi-state affiliates actually do
For an affiliate business operating nationally, the practical result is a rolling compliance calendar rather than a single licensing decision. A network cannot assume that a Pennsylvania registration covers Michigan, or that a CPA deal that only needs light paperwork in New Jersey stays light if the same affiliate later negotiates a revenue-share arrangement in Colorado.
That is one reason the sector's larger networks, Better Collective, Catena Media and Gambling.com Group among them, run dedicated compliance functions rather than treating state licensing as a one-time setup cost. It also shapes how affiliates structure sub-affiliate programs: a master affiliate holding a state license still needs to know how its sub-affiliates get paid, because a sub-affiliate on revenue share can trigger the same heavier license tier as if the master affiliate were on that model itself.
It intersects with advertising compliance too. Google's own gambling affiliate ad policy already requires affiliates to certify state-by-state legality before running search ads, so an affiliate that is not properly registered in a licensing state risks a compliance problem with its traffic source as well as its state regulator.
What to watch
More states are moving toward explicit affiliate rules as new sports betting markets open, following the pattern set by New Jersey, Pennsylvania and Michigan rather than Ohio's lighter-touch approach. Any affiliate business planning multi-state expansion needs to budget for that trend now: state licensing fees and background-check costs, not traffic acquisition, are increasingly the first real barrier to entering a new market, well ahead of the marketing spend that follows.
For entrepreneurs weighing where to launch an affiliate site next, the practical filter is simple. Check whether the target state licenses affiliates at all, then check which commission model keeps that license process light. Building the wrong payout structure into a contract before checking the state's rule can turn a simple registration into a full supplier application months into a launch.
Background-check timelines add a second variable that is easy to underestimate. Pennsylvania's certified-provider track requires personal history disclosures for every owner and officer involved in soliciting business, a filing that can take longer to clear than the affiliate's own sales pipeline for a new state. Vendor-level registrations in Michigan, New Jersey, Indiana and Colorado move faster precisely because they skip that layer of individual disclosure, which is the real reason so many affiliates still prefer a flat-fee or CPA structure in states with heavier licensing regimes, even as the industry's broader economics push toward revenue share. None of this is static, either: states that launched without affiliate rules have added them after the fact, and a compliance plan built once at launch is one that will eventually miss a renewal in a state the affiliate already operates in.
