Navigating the maze: US market decoded for European affiliates

The US market is often described by European affiliates as the “New World” of iGaming – vast, lucrative and full of untapped potential. 

But for those used to the relatively centralised (though increasingly regulated) frameworks of the UK, Malta or Scandinavia, the US landscape can feel less like a unified market and more like a high-stakes puzzle.

At Vault Network, we speak with European partners daily who are eager to scale across the Atlantic but are paralysed by compliance friction. The transition isn't just a gimmick of changing "football" to "soccer". Affiliates need to navigate a fragmented regulatory environment that demands a total rethink of their technical and content infrastructure.

With that in mind, I am happy to share our strategic guide for European affiliates looking to turn the US pain point into a competitive advantage.

Mindset shift from national to state-by-state

The biggest mistake European affiliates make is treating the US as a single entity. In reality, you are entering a vast number of distinct markets, each with its own licensing requirements, tax structures and marketing restrictions.

While some states allow for revenue share, others strictly mandate CPA models. Some states allow the use of “free bet” in promotions, while others have banned the term entirely.

So don’t try to conquer the country at once. We recommend two entry paths:

• The geographic cluster: Prioritise high-liquidity, regulated sports betting states like New Jersey, Pennsylvania or Ohio. Ensure your tech stack can handle geo-specific offers (for example, if a New York user sees a New Jersey only promo, you’ve lost a conversion and potentially flagged a compliance violation).
• The vertical specialist: Instead of tackling all operator types, focus on a single vertical like daily fantasy sports (DFS), sweepstakes or prediction markets. This allows you to target massive, high-population states like California, Texas, Florida and Georgia. While true real-money sports betting isn't live in these states, they do have massive appetites for DFS and alternative gaming options, providing a huge footprint without the complexity of full sportsbook licensing.  

Business model flip: from rev share to CPA

One of the most jarring shifts for European affiliates is the move away from revenue share. While Europe is built on long-term "tail" revenue, the US market is almost exclusively driven by CPA.

This changes your operational DNA. On a revenue share model, you monitor player lifetime value over months or years; on a CPA model, you manage a high-velocity performance business. You need to know exactly when a user hits a deposit or wagering trigger to unlock your payment.

• The strategy: Tighten your feedback loops. Because the US is a CPA-first market, your ability to scale depends on how quickly you can see conversion data and reinvest that capital into your winning traffic channels.

Solve the data fragmentation nightmare

In Europe, tracking is relatively streamlined. In the US, the sheer volume of operators, state-specific links and varying reporting standards creates a massive administrative burden. Affiliates often find themselves logging into 10+ separate dashboards just to see their performance for a single Tuesday night.

To scale in the US, you need a "single pane of glass" – one centralised hub that aggregates data across every state and every operator. This is a primary reason we built our proprietary dashboard at Vault. 

• The strategy: Transition away from manual spreadsheets and siloed logins. Use a unified dashboard to automate your reporting, but don't just watch the numbers. Leverage real-time data to optimise and make instant adjustments to your campaigns. When you can see which state or which vertical is over-performing in one clean view, you can pivot your spend and strategy much faster than the competition.  

Compliance as a commercial tool

Many affiliates view compliance as a brake on their business. In the US, it is actually the engine. The regulatory barrier to entry is high, so those who get it right from the start gain immediate trust with tier 1 operators, allowing them to ultimately generate more affiliate revenue in the long run. 

Regulatory nuances in the US are granular. For example:

• Terminology: In most US jurisdictions, you cannot use the word "bet" when promoting DFS. You must use "picks".
• Disclosures: Responsible gaming messaging isn't just a footer. It often requires specific location requirements, such as state-specific hotline numbers depending on where the traffic originates.
• The strategy: Automate your compliance. Work with partners who provide compliance-ready creative assets and links that update dynamically based on the user’s location.

Add new media into your traffic mix 

The US market is currently being driven by a shift toward creator-led marketing. While SEO remains important, influencers, streamers and social-first content are capturing a massive share of the younger betting demographic.

European affiliates who rely solely on traditional review sites may find the US acquisition costs (CPAs) prohibitively high.

• The strategy: Look toward new media channels. Integrating YouTube, Discord or localised social content into your mix can lower acquisition costs and build a more loyal community than search traffic alone.  

The path forward

The US market doesn't reward those who move fast and break things. Instead, it rewards those who move fast and build systems. The pain points of compliance and data management are exactly what keep your competitors on the sidelines.

By utilising a sophisticated dashboard and a state-first strategy, you can stop viewing the US as a risk and start viewing it as a predictable growth engine. And there is no better time to build that foundation than right now. As we look ahead to the 2026 World Cup, hosted across North America, we anticipate one of the largest player acquisition events in history. European affiliates who have their US systems battle-tested today will be the ones positioned to capture that massive wave of traffic.
