AI shopping agents put Amazon’s $69B ad business at risk
Amazon generated $69 billion in advertising revenue in 2025. Most of that money flows from brands paying to appear at the moment a shopper searches for something to buy. AI shopping assistants threaten to cut that moment out entirely.
The a16z analysis lays out the mechanics clearly. When an AI agent handles product discovery and routes the order directly to a fulfillment provider, the marketplace loses its position in the customer relationship. It may still ship the box, but it no longer controls the decision. That distinction matters enormously to the ad and commission economics that make platforms like Amazon profitable.
Who benefits and who gets squeezed
Not every platform loses here. Shopify and Toast are cited as platforms with more reason to welcome agents. They already earn on software and payments, so new AI-driven sales add volume without cannibalizing a discovery ad product they don’t rely on.
Marketplace-first platforms face the harder tradeoff. Fulfillment revenue stays, but the high-margin advertising layer is exposed.
The open question
The outcome hinges on one variable: whether AI agents create net new purchasing behavior or simply reroute orders that would have happened anyway. If agents expand total demand, lower per-order profit can be offset by higher volume. If they just redirect existing intent, the math gets worse for any platform that monetizes discovery.
For operators building in e-commerce or selling on marketplaces, the implication is worth tracking. The platforms that own the customer conversation going forward will set the terms for everyone selling through them.
