The trillion pound question: who verifies the agent?

OneID and the trust layer for agentic commerce

AI agents are moving from recommending purchases to making them. They'll handle the weekly shop, renew insurance, book travel and run B2B procurement. McKinsey estimates the agentic commerce opportunity at $3–5 trillion by 2030.

Card networks, wallet platforms and AI providers are building the rails that let agents pay, and they're moving fast. What remains unsolved is trust, and that is what will decide how quickly this market grows.

The trust gap merchants can't absorb

Payment infrastructure assumes a human is present when a purchase is authorised. A card authorisation proves the card is valid and funds are available. It doesn't prove that an agent acted for a verified person, that the person approved this specific purchase, or that the agent stayed within its limits.

That leaves merchants exposed. Compromised or rogue agents can transact at machine speed, and customers can plausibly dispute purchases their agents made. If the merchant can't prove authority, the merchant takes the loss. The question isn't whether agents can buy. It's whether merchants can safely sell to them.

What OneID is building

OneID is extending its identity platform to become the independent trust layer for agentic commerce, binding a verified human, their approved intent and the limits of their authority to every agent-led transaction.

Before an agent acts, the proposed transaction is shown to the user through OneID's own trusted interface rather than the agent's, so an agent can't present one thing and do another. The user approves it in a single action, and OneID cryptographically signs the mandate against their verified identity. Users set limits on spend, merchant categories, frequency and data sharing, and the platform enforces them. Every action produces audit-grade evidence that holds up in a dispute. A real-time risk engine can pause or revoke authority when an agent's behaviour looks wrong.

Why OneID is positioned to lead

This builds on assets OneID already has. Our Digital Verification Service is certified under the UK Digital Identity and Attributes Trust Framework, which is a meaningful barrier to entry. Our orchestration layer already connects bank identity, government credentials, digital wallets and document verification, and agentic commerce needs that global reach from day one.

Neutrality matters just as much. Payment networks and wallet platforms are incentivised to enable transactions, not to protect merchants from liability, and none of them is a cross-platform identity authority. OneID can serve every participant. As transaction volume grows, our reputation data, which links verified identity, agent behaviour and merchant outcomes, becomes a compounding advantage that is hard to replicate.

The opportunity reaches well beyond retail, into marketplaces, subscriptions, travel, financial services, procurement and regulated sectors where eligibility has to be proven.

Execution is being solved. Trust is the opportunity, and OneID is building the infrastructure to capture it.
