The most durable commercial model of the last two decades has a simple structure: make the customer relationship deep enough, sticky enough, and multi-product enough that the switching costs compound over time. Land with one product. Expand into others. Build an identity layer that connects every interaction. Make every new product adoption increase the value of the ones that came before it.

That model is now showing up in sports and entertainment, and the proof arrived in a cluster of deals signed over the past four weeks.

American Express launched a co-branded Fanatics credit card in May, becoming the official payments partner at Fanatics locations globally and a Membership Rewards transfer partner in 2027. AT&T signed a five-year deal with Fanatics to become the "Official Connectivity Provider of the Fan," giving AT&T subscribers elevated loyalty status and additional FanCash earning. Last week, Spotify and Live Nation announced a multi-year partnership where Spotify will analyze Premium subscribers' streaming habits to reserve concert tickets for an artist's biggest fans before general public sales.

Three deals from three different industries, all built on the same commercial logic: fandom is shifting from a seasonal merchandise business to a membership economy, and the companies that recognized it first are now building the infrastructure to capture it.

The fan as enterprise account

Fanatics ONE, the company's loyalty program, has tripled to 30 million members in eight months. FanCash, its currency, is on track to issue over $1 billion this year with a 97% redemption rate. Six months ago, Fanatics was primarily known for merch and collectibles with a growing sportsbook. Today it operates across merch, collectibles, sportsbook, ticketing, live events, content production (Fanatics Studios launched in January with ESPN, WWE, and LA28 Olympics deals), payments, and connectivity. Each new vertical feeds the same identity and rewards layer, which makes the next partnership more valuable than the last.

That's the enterprise playbook applied to fandom. High lifetime value. Multi-product adoption. Switching costs that compound with every new service connected. Usage data that informs the next expansion. Fanatics ONE is the CRM. FanCash is the engagement metric. Each new partner is an expansion deal.

Every deal is an expansion play, not an acquisition campaign

In enterprise, the most valuable revenue isn't the initial sale. It's what happens when an existing customer adopts a second product, then a third. Each adoption increases the switching cost. 

That's the commercial motion underneath every deal Fanatics has signed this year. 

Amex isn't acquiring 30 million new cardholders from scratch. It's offering a financial product to 30 million fans who already transact frequently, emotionally, and across multiple categories inside an ecosystem they're invested in. The card works because the relationship already exists. AT&T is using Fanatics ONE tier status as a retention tool for wireless subscribers. A customer earning FanCash through their phone plan has a reason to stay that has nothing to do with network coverage or price. The switching cost is the loyalty tier they've built, not the service itself.

A fan who earns FanCash through an AT&T plan, spends it on merch, earns more through an Amex card, and gets presale ticket access through their Fanatics ONE tier has compounding switching costs across four products. Leaving any one reduces the value of the others. That's the same dynamic that makes enterprise software customers so difficult to displace, playing out in sports fandom.

Why this is different from traditional sports partnerships

Sports sponsorship has existed for decades and co-branded credit cards aren't new. What's new is the infrastructure underneath these deals.

A traditional sponsorship buys visibility. A jersey patch, a stadium naming right, a halftime spot. The value is measured in impressions and brand lift. The relationship between the sponsor and the fan is indirect: the sponsor pays the team, the team delivers the audience, and the sponsor hopes the association transfers.

These deals are structurally different - 

• AT&T isn't buying visibility among Fanatics' fans. It's plugging into an identity layer that gives AT&T subscribers a tangible, ongoing benefit tied to their phone plan. 
• Amex isn't sponsoring Fanatics events. It's issuing a financial product whose value proposition depends entirely on how deeply the fan participates in the Fanatics ecosystem. 
• Spotify isn't putting its logo on a concert stage. It's turning its own behavioral data into a credential that unlocks inventory inside Live Nation's ticketing system.

The value isn't measured in impressions. It's measured in how many fans adopt the partner product, how long they retain, and how much incremental spending flows through the connected ecosystem.

Where this is heading

The more interesting question is what happens when these ecosystems overlap. A fan who uses Spotify, buys merch on Fanatics, holds the Amex card, and buys Live Nation tickets is generating behavioral data across four separate ecosystem plays that don't yet talk to each other. The company that figures out how to connect those signals, whether through partnerships or through a shared identity layer that spans them, builds the most valuable fan profile in entertainment. And every brand trying to reach that fan will pay a premium to access it.

That race is just starting. The partnerships announced in the last four weeks are the opening moves.
