How Affiliate Marketing Opens the Door to AI-Driven Commerce

Consumers are using artificial intelligence for shopping more and more as time goes on. PYMNTS surveyed nearly 6,0000 consumers and more than 1,100 merchants for its June Global Digital Shopping Index, which revealed that 47 percent of shoppers used AI in some way during their last purchase.

But using AI for shopping goes beyond simply working with AI to ask product research questions. Consumers are increasingly ready to let AI agents research, compare, and possibly even to buy products on their behalf. In a BigCommerce survey of 3,000 online shoppers across the United States, United Kingdom, and Australia, roughly two-thirds of consumers across all three regions said they're interested in trying agentic shopping tools.

That shift creates an obvious problem for companies: how do you show up in a transaction driven by machines talking to machines and how do you pay the machine that got you there?

Marketers scrambling for an answer are looking toward net-new technology budgets to pay for emerging tools such as custom APIs, agent partnerships, and experimental ad formats built for a still-nascent market. But the more useful (and realistic) answer might already be sitting inside the marketing organization, in a function many companies have spent the past decade treating as a bottom-of-funnel channel: affiliate marketing.

The mechanics already fit.

Affiliate marketing was built to solve a version of this exact problem. It exists in large part to monetize the demand created through companies' combined marketing efforts. Affiliate marketing works through distributed content that lives outside companies' own properties, it operates on embedded links that carry attribution wherever that content travels, and it is paid for by companies only on a cost-per-acquisition basis, meaning in most cases that companies only spend money when sales actually happen.

That is precisely the operating model AI shopping assistants and agents need. An AI recommending a product is essentially a publisher and not all that different from an influencer recommending a product and providing a special link. An agent making a purchase on behalf of a shopper arguably still needs to be compensated in some way for having found and purchased that product.

If any AI tool uses a tracked link and gets paid when the recommendation converts, it's running an affiliate program, whether anyone calls it that.

This isn't hypothetical, even if no AI platform has begun a true affiliate marketing/referral-fee- style compensation plan yet. OpenAI did begin charging merchants a 4 percent transaction fee on completed purchases through ChatGPT's now-defunct Instant Checkout in early 2026. This has evolved somewhat: OpenAI now charges a 4 percent transaction fee through the Agentic Commerce Protocol it's offering as an AI commerce standard. Likewise, Amazon has attached cost-per-click charges to product placements inside itsAI agent, Alexa for Shopping (formerly Rufus).

Both are proof that platforms are comfortable taking a cut of AI-influenced or AI-completed commerce. But neither is an affiliate program in the traditional sense; instead, they're fees that each platform charges merchants directly, not commissions paid for referring a sale.

That gap is the opportunity. The compensation model that pays a referring party for a completed, tracked conversion, is exactly the model affiliate marketing has had in place for two decades.

The infrastructure question is already solved.

The part that looks to be the most technically difficult is often the part affiliate networks and platforms have already built. Attribution, fraud detection, and conversion tracking, the hidden plumbing that makes a CPA-based program actually work at scale, are exactly what any AI shopping layer needs before it can respond to a request like "find me the best price on this item" and earn a merchant commission for sales generated from the answer or the agent purchase.

In addition, affiliate infrastructure has long been tested and has successfully resolved issues related to fraud, disputes, and attribution/tracking audits. It also already operates at meaningful scale: EMARKETER forecasts affiliate-driven US ecommerce sales will reach $241 billion in 2026.

This is proof that affiliate marketing is not some new channel needing to prove itself; rather, it's a mature system already generating hundreds of billions in tracked, attributed sales for thousands of merchants. As EMARKETER pointed out, "This suggests the channel is no longer a niche tactic but a core component of e-commerce infrastructure."

None of this requires waiting for the agentic commerce landscape to mature or for a dominant AI chat-to-commerce platform to emerge. It means ensuring the affiliate infrastructure that already exists provides the answers to questions such as the following:

• Does tracking persist past the handoff between an AI and a checkout page?
• Is the measurement framework capable of attributing sales to AI agents buying with limited human oversight?
• Are commission structures flexible enough to accommodate a new category of AI-native publishers?

The bigger shift underway isn't just technical. As customers shift to using AI for shopping, they are asking more and searching less. Affiliate marketing is the channel that's already been built so referrers, in this case chatbots or AI agents, get paid when that ask turns into a purchase.
