Agentic commerce just got its most important infrastructure upgrade yet. At Stripe Sessions 2026, Stripe announced that its Link digital wallet — used by 250 million people for personal payments — is now extensible to autonomous AI agents. Combined with a new Agentic Commerce Protocol, a Google partnership for in-AI checkout, and 288 additional product features, this is the biggest single-day product announcement in Stripe’s history for the agentic space.
Link Wallet for AI Agents: How It Works
The core problem Stripe is solving: AI agents that make purchases on your behalf need payment credentials to do so, but handing an agent your card number is a terrible security practice. Stripe’s solution is OAuth-based delegation.
Here’s the flow:
- User authorizes the agent: You grant a specific AI agent access to your Link wallet via OAuth — the same pattern used for third-party app permissions
- Agent gets a one-time instrument: For each transaction, the agent receives either a one-time-use virtual card or a Shared Payment Token (SPT) — neither exposes your actual card credentials
- Transaction executes, then token expires: The payment instrument is single-use; even if intercepted, it can’t be reused
- Coming soon: User-defined spending limits and scheduled approval flows so you can say “this agent can spend up to $50/day without asking me”
This is meaningfully different from the ad-hoc workarounds agents currently use (stored API keys, browser automation of checkout flows). The Stripe approach gives agents a payment identity that is cryptographically scoped, auditable, and revocable.
Agentic Commerce Protocol (ACP)
Beyond Link, Stripe announced the Agentic Commerce Protocol — a new standard for how AI agents interact with the Stripe payment stack. The ACP is documented at docs.stripe.com/agentic-commerce/acp and defines:
- Standard authorization handshakes for agent-initiated payments
- Token lifecycle management (issuance, use, expiry)
- Merchant-side verification that a transaction came from an authorized agent (not a spoofed request)
Think of it as OAuth for payments, specifically designed for the agentic runtime model where the entity initiating the purchase isn’t a human sitting at a browser.
The Google AI Mode Partnership
Stripe announced a partnership with Google to enable checkout directly inside Google’s AI Mode — the conversational search and shopping interface. This means users interacting with Google AI Mode for product research can complete purchases without leaving the AI interface, with Stripe handling the payment rail underneath.
The integration uses Gemini as the AI layer and Stripe as the commerce infrastructure — a combination that positions both companies against emerging Amazon Agentic Commerce efforts.
Runloop Joins Stripe Projects
Runloop — a startup building scalable infrastructure for AI agent environments — is joining Stripe Projects, Stripe’s ecosystem of supported partners. Runloop’s infrastructure is specifically designed for agents that need to spin up isolated compute environments quickly, which pairs naturally with agents executing commerce workflows that require sandboxed execution.
Why This Changes the Game
The “AI agent that shops for you” concept has existed in demos for years. What’s been missing is a payment rail built for agents rather than humans. Credit card credentials are designed for human-controlled use; they don’t have the scoping, revocation, or delegation semantics that agent-native payments require.
Stripe’s Link extension, the ACP, and the SPT architecture are the first serious attempt to build that infrastructure. For developers building agents that involve commerce — travel booking, procurement, subscription management, B2B ordering — this unlocks workflows that were previously either impossible or deeply insecure.
The scope of the announcement (288 new features announced at the same event) also signals that Stripe is treating agentic commerce as a first-class product line, not an experimental side project.
