TL;DR: Agentic AI is changing online shopping by offloading research, deal hunting, cart building and even higher-stakes purchase tasks, while merchants start seeing shorter sessions, thinner device signals and more AI-chat referrals, according to Signifyd. The governance challenge is no longer whether agents buy, but how to distinguish legitimate agent-led commerce from automation that breaks legacy fraud models.
Editorial analysis by NHI Mgmt Group, based on content published by Signifyd: “Why Agentic AI? How to Build Trust in the New Commerce Journey”.
By the numbers:
- 38% of U.S. consumers are already leveraging AI for help with their online shopping tasks, according to Adobe.
- 86% of ecommerce shoppers say saving money is a motivator to use agentic AI agents, according to a study by Wildfire Systems cited by Signifyd.
- 50% of all Cyber Week orders in 2025 included a discount code, Signifyd says in its State of Global Commerce 2026 report.
Key questions
Q: How should merchants handle fast AI-led shopping sessions without blocking real customers?
A: Treat fast, narrow sessions as a normal pattern when they include consistent purchase context, but do not trust speed alone.
Q: Why do agentic shopping journeys break legacy fraud signals?
A: They break them because older models assume browsing depth, device continuity, and session entropy are strong proxies for legitimacy.
Q: What are the signs that agent-led commerce is showing up in merchant analytics?
A: Look for short sessions with unusually high conversion, fast paths to product pages, thinner device identifiers, cloud-region traffic, and more AI-chat mentions with flat click-through rates.
Practitioner guidance
- Instrument agentic-session signals Add detection for short sessions, rapid PDP traversal, AI-chat referrals, and thin device identifiers so merchant analytics can distinguish delegated shopping from noise.
- Tune fraud models for delegated intent Recalibrate scorecards so fast checkout after upstream comparison is not automatically treated as bot behaviour when other trust signals remain consistent.
- Separate human and agent journeys in telemetry Track whether discovery, comparison, and checkout occur in the same session, then flag cases where the purchase arrives pre-qualified through an external agent.
Bottom line: Agentic commerce changes the evidentiary model for fraud because the shopper’s intent may be established upstream of the merchant session.

Agentic commerce creates an intent attribution problem, not just a fraud problem. The merchant is no longer classifying a single user session, but a layered interaction where discovery may happen in one system and purchase in another. That breaks older assumptions in identity and fraud governance because the actor at the point of checkout may be a delegated agent carrying the shopper’s intent without carrying the shopper’s usual behavioural trail. Practitioners should treat delegated intent as a first-class governance object.
A few things that frame the scale:
- 53% of security leaders expect AI to run major portions of their infrastructure autonomously within the next three years, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: Should fraud and identity teams use the same controls for human and agent-led transactions?
A: No. Human and agent-led transactions share the same commercial goal, but they present different evidence about identity, intent, and device continuity. Teams should keep a single governance model for trust decisions while using different signals and thresholds for each journey type. That prevents both false declines and blind acceptance of automated abuse.
