Users have grown comfortable sharing data with tech platforms, but AI agents will be different. They won't just learn about us; they will act on our behalf—buying things, sending personal messages. This deeper level of agency will force users to scrutinize the incentives and alignment of the models they use.

AI shopping agents will disrupt e-commerce models that rely on human browsing for data collection, recommendations, and upsells. When agents perform these tasks programmatically, sellers lose this crucial interaction and must pivot to building agent-friendly interfaces and incentives, effectively selling to an algorithm.

A new bill from Senator Mark Warner introduces a "duty of loyalty" principle, which would legally require AI agents to act in the user's best interest, not the developer's or an advertiser's. This applies a fiduciary-like responsibility to software.

While payment security is a concern, a bigger hurdle for AI commerce adoption is the question of liability. A significant percentage of consumers believe the answer engine platform would be liable for a botched transaction, a trust threshold that platforms and brands must address before adoption can accelerate.

In the agentic economy, brands must view their AI systems not just as tools, but as potential vulnerabilities. Customer-side AI agents will actively try to game your systems, searching for loopholes in offers, return policies, and service agreements to maximize their owner's benefit. This necessitates a security-first approach to designing customer-facing AIs.

Senator Mark Warner's proposed bill introduces a "duty of loyalty" for consumer-facing AI agents. This legal framework would bar agents from prioritizing their provider's business interests (e.g., undisclosed partnerships) over the user's best interests, shifting regulatory focus to economic alignment and consumer protection.

Numerous consumer finance and service industries rely on friction and customer breakage to generate profit, such as delayed insurance claims, complex rebates, or high credit card interest rates. Chris Farmer and Shiel Monat suggest that relentless personal AI agents will automate tasks like refinancing debt or fighting airline refunds, leveling the playing field and forcing legacy businesses to eliminate artificial bureaucratic hurdles to retain customers.

While AI shopping agents promise to protect consumer privacy by abstracting away direct retailer relationships, this is a false dawn. Power will likely centralize with the major tech companies providing these agents, not empower individual users with decentralized control. The battle for "owning the customer" simply moves to a new layer.

Amazon is suing Perplexity because its AI agent can autonomously log into user accounts and make purchases. This isn't just a legal spat over terms of service; it's the first major corporate conflict over AI agent-driven commerce, foreshadowing a future where brands must contend with non-human customers.
