Up to this point, the challenges of agentic commerce can still sound abstract. Fragmentation feels manageable. Delegation sounds solvable with enough product logic. Initial deployments often work precisely because their scope is constrained.

The trouble starts when systems need to scale.

Early implementations tend to encode trust directly into application logic:
• UI flows that imply consent
• session state that carries context
• platform-specific assumptions about who is acting and why

That approach works when systems are closed and humans are always in the loop. It breaks down when those assumptions stop holding.

As agentic systems operate across platforms, delegate authority beyond a single interface, and produce outcomes that must be explainable later, trust can no longer remain implicit or contextual. It has to stand on its own.

This is where standards enter the picture — not as ideology, and not as a quest for elegance, but as a practical response to scale.

Standards emerge when ecosystems need shared ways to answer the same questions repeatedly:
• who is authorised to act
• what limits apply
• what information was disclosed
• and whether an action can be independently verified after the fact

Hard-coding those answers into individual applications doesn’t scale. Each new integration becomes a bespoke negotiation. Each new participant increases complexity. Each exception weakens the overall system.

At some point, trust has to move out of application logic and into shared, portable primitives.

This doesn’t imply centralising control or removing competition. It means agreeing on how authority and consent are expressed, so they can be verified consistently across different systems, organisations, and jurisdictions.

We’ve seen this pattern repeatedly. Payments, identity, and network security all went through similar phases: early innovation, fragmented execution, followed by convergence around shared trust mechanisms once scale made ad-hoc approaches untenable.

Agentic commerce is no different.

What’s changing isn’t the nature of trust itself, but the environments in which it needs to operate. As software takes on more responsibility, trust has to become explicit, portable, and verifiable — not because standards are fashionable, but because complexity leaves no alternative.

This is the point at which standards and infrastructure start to matter more than individual implementations — not as an architectural preference, but as a practical consequence of scale.
