If AI agents start doing our shopping for us, can brands still win customers — or just win over the bots?

This explores whether brands can still compete once AI agents sit between them and the shopper, deciding what gets considered and bought. The corpus's short answer is yes, but the contest moves. Brands would no longer mainly compete for human attention. They would compete to be picked by an agent. One note describes this as an 'agent attention economy': services start optimizing to be chosen by agents instead of clicked by people, and ranking and ad-like systems grow up around that new audience Will agents compete for attention just like users do?. Persuading a person and being selected by software are different skills, and that is the main change.

Who owns the agent may matter more than how good the brand is. MIT researchers argue that whoever builds and maintains an agent sets its goals. Platform-built agents tend to serve sellers by default, while agents the consumer controls can be set up around the buyer's interests Does agent ownership determine whose interests get optimized?. Ad-funded shopping agents add a further risk: placement fees can tilt recommendations no matter how well the agent is engineered Do advertising-funded shopping agents favor paid product placements?. So for a brand, 'competing' might mean paying for placement in someone else's agent, or building its own. Accenture's survey suggests consumers say they prefer retailer-built agents. That is a stated preference from a survey, not proof that such agents work at scale Will brands succeed by building their own AI shopping agents?. Whether platforms end up open to many agents or closed around proprietary ones, the way payment networks split, will decide how many entry points a brand has Will agentic commerce platforms adopt open or closed models?.

Some of this cuts in brands' favor. Choudary argues that agents acting only for the buyer change where shoppers enter a market but not how the market works. Real structural change needs seller-side agents that negotiate with buyer-side agents Do one-sided consumer agents actually change market structure?. That suggests a brand's strongest move is to field its own agent, not just optimize for other people's. Microsoft researchers argue that cutting the friction of communication between consumers and businesses lowers switching costs and could redistribute market power Could agent-to-agent communication reshape market power?. Andrew Chen adds that agents lack network effects, because they can talk to each other through standard interfaces and swap the model underneath Do AI agents actually benefit from network effects?. If he's right, no single agent becomes an unavoidable gatekeeper, which is good news for brands that worry about one dominant platform.

The less obvious point is that cheap agent search doesn't automatically reward the best brand. A 2026 market-design paper argues that imperfect agent search, plus near-identical product descriptions that are easy to generate, plus a flood of low-quality sellers, can leave markets worse off than before Can cheap agent search actually harm shopping markets?. In that world, a brand's edge may come from being clearly different and easy for a machine to read, not from producing more content. A formal model finds that an algorithm's advantage over ordinary seller competition shrinks as markets fill with sellers Does algorithmic recommendation lose its edge as sellers compete more?. Agents may reshape niche markets more than crowded ones. On pricing, the UK competition regulator (the CMA) warns that brands' own pricing agents could learn to soften competition with each other without any explicit agreement Could autonomous pricing agents dampen competition without explicit collusion?.

The idea you might not expect: brand loyalty may stop forming only in the shopper's head. Bilgihan and colleagues argue that agents which actually complete purchases help build what consumers want through repeated back-and-forth, so preferences form inside the loop between person and agent Do AI shopping agents reshape what consumers actually want?. The brand's real battleground may be the agent's memory of the user. One caveat: most of this material is argument, models, or surveys. The corpus doesn't yet have strong evidence on how brands actually fare once agents do the choosing.
