Agentic Commerce

What happens when AI agents handle payment and banks become optional?

The Spine​

Zoom Out​

Agentic commerce is the economic rail for autonomous transactions — discovery, negotiation, checkout, authorization, settlement, and proof — projected to reach $3-5 trillion by 2030. Three protocol families compete to be the default: ACP (OpenAI + Stripe), AP2 (Google), and x402 (Coinbase + Google + Ethereum Foundation). The real question underneath every standard is the extraction test: does it reduce extraction or just relocate it to a new patron who controls the routing table? Extraction disappears only when the standard is open enough that no single gatekeeper owns the rails.

The Extraction Test​

Every standard faces one question. Does it reduce extraction, or relocate it to a new patron who controls the routing table? The rails pass only when no single gatekeeper owns them.

Verifiable Intent​

Autonomous checkout needs a cryptographic chain from human approval to agent action. That consent primitive lets an agent transact without a human tap at each step.

When To Use​

Use this map when choosing a commerce protocol or settlement rail. Name who controls the routing table before you commit.

Context​

  • Three Flows — Messages, money, data: same architecture, same settlement pattern
  • Sui — Settlement layer: ~390ms finality, PTB batching, Move safety
  • Stablecoins — The settlement instrument
  • Payments Industry — $25T B2B cross-border friction meets stablecoin efficiency
  • Phygital Beings — The actors who transact: devices, agents, and humans wearing different hats
  • A2A Protocol — How agents coordinate before they transact
  • UCP — Google's Universal Commerce Protocol — the commerce operations layer
  • AP2 — Google's Agent Payments Protocol — payment authorization via VDCs
  • Payment Rails — Intent-based payment infrastructure
  • Agency — Protocols enable the capability side of agency
  • A&ID Template — Visual language for agent-instrument systems
  • Financialization — Same game on different rails?
  • Standards — What survives from experiment to adoption
  • Peaq — Economy of Things — Machine identity and settlement for DePIN device commerce
  • Agent Protocols — Physical agent coordination stack
  • Protocols — Rules for making progress

Questions​

When agents handle money, does the extraction move or disappear?

  • If ACP (OpenAI + Stripe) and AP2 (Google) both succeed, does interoperability emerge or do agents pick sides?
  • What breaks when regulation requires "human oversight" for transactions that happen at machine tempo?
  • Is the honest answer that every standard has a patron — and the question is which patron extracts the least?

Changes my mind: evidence that a single-patron protocol wins agent commerce while staying genuinely open and non-extractive would break the extraction-test framing.

Next question: which layer — identity, execution, or settlement — locks in first, and does that decide who owns the routing table?
