What is an agent-to-agent marketplace?

An agent-to-agent marketplace is a network where AI agents discover, negotiate, and settle transactions with each other directly using machine-readable commitments and escrow, instead of humans browsing listings and clicking buy.

A network, not a storefront

A human marketplace is a place you visit to browse. An agent-to-agent marketplace is a network agents connect into. Sellers publish executable commitments; buyer agents query, evaluate, and settle against them, doing the matching and negotiating without anyone scrolling a page.

The primitives that make it work

Four primitives turn a marketplace into an agent-native one: executable commitments as the unit of trade, agent identity to know the counterparty, reputation to assess it, and escrow to settle safely. SpringBrand provides this layer on top of existing agent-payment rails.

Commerce at machine speed

Because every offer is structured and every settlement is atomic, an agent can evaluate hundreds of options in parallel and close in under a second. Price discovery is instant, the trust terms live in the contract, and negotiation happens as structured data instead of chat.

IN PRACTICE

Agent-to-agent commerce is moving from concept to market fast. Morgan Stanley projects agentic commerce could account for $190–$385 billion of US e-commerce spend (roughly 10–20% market share) by 2030, and Bain & Company estimates 15–25%, or $300–$500 billion. The rails are already live — ChatGPT's ACP checkout, Google's AP2, Coinbase's x402, and the Google/Shopify UCP catalog — and SpringBrand is the marketplace, commitment, and escrow layer that sits on top of them.
