Stripe says AI agents are shopping through its Link payment service at a rapidly accelerating pace, with transaction counts growing 38-fold and payment volume growing 20-fold in September, according to a report by Upstarts Media covered by The Decoder on Monday. The company has not disclosed how many purchases or how much money sit behind those multiples, and acknowledged the growth started from a small base — but executives argue the trajectory is what matters.
Dan Hill, a Stripe executive overseeing the effort, said the volume is now becoming significant. When Stripe ran its analysis, about 70 agents were using Link to make purchases on their users' behalf; that number has since grown to around 200, Hill said, including Meta's Muse assistant and xAI's Grok Bot.

What Agents Are Buying
Most agent-driven purchases are modest. Hill said the typical transaction is about $100, though some users instruct their agents to book flights or buy furniture worth thousands of dollars. Retail accounted for 36 percent of transactions and 32 percent of volume, while travel was the next-largest category at 28 percent of volume.
The figures are the clearest quantitative signal yet that agentic commerce — AI assistants autonomously completing purchases — is moving from demos to real spending. The scale caveat is important: Stripe declined to publish absolute numbers, and a 38-fold increase on a small base can still represent a rounding error in a payments network that processes trillions of dollars annually. Stripe's decision to keep the totals private makes independent assessment impossible for now.
How Link Handles Agent Payments
Link is Stripe's accelerated checkout product, built around one-click payments that store a customer's payment details for reuse across Stripe-powered merchants — and Stripe now lists agentic commerce as a distinct use case on its own site. The mechanism for agents is deliberately conservative. Link does not hand agents the user's real credit card number. Instead, the service issues a separate 16-digit virtual card number for agent use, and users can set spending limits on what their agents are allowed to do. That containment model is becoming the standard answer to the obvious trust problem: an agent with a raw card number and an unclear instruction set is a fraud and liability risk, while a capped virtual card is a manageable one.
Hill noted that Anthropic and OpenAI both use Link, though not yet for agent purchases — an indication that the two companies building the most widely used AI assistants have not yet flipped the switch on autonomous spending for their mainstream products.
A Market in Its Earliest Days
Stripe is not assuming it will own this channel. Hill named PayPal and Shopify's Shop Pay as competitors in agent payments and described the market as still in its very early days.
The competitive framing reflects a broader land grab over agentic commerce rails that has been building all year. In September, The Wall Street Journal reported that Mastercard partnered with virtual card startup Alchemy to let AI agents pay anywhere Mastercard is accepted online, joining Visa, which had already cleared agent purchases through virtual credentials. Anthropic, for its part, launched a Claude for Commerce Agents blueprint with Shopify and Priceline among early users, handing merchants reference implementations for shopping agents. And the rails run in both directions: Amazon blocked Meta's Muse agent from shopping on Amazon.com, calling it an unauthorized agent in an error message first spotted by GeekWire — evidence that agent access to major retailers is contested, and that the checkout layer is becoming a strategic chokepoint between AI platforms and commerce companies.
Stripe's own positioning extends beyond payments. The company closed a reported $7 billion-plus acquisition of OpenRouter, the routing layer for hundreds of AI models, in August — placing it inside the AI infrastructure stack that agents depend on, with Link now emerging as the spending side of that strategy.
Why the Numbers Matter
For the AI industry, Stripe's data offers the first scaled evidence that consumers will let agents complete real transactions, not just research products. An average spend of roughly $100 per transaction, spanning retail and travel, suggests early usage skews toward practical errands rather than novelty purchases.
For payments companies, the strategic question is who becomes the default credential and authorization layer for agents. If agent commerce follows the trajectory that Stripe's multiples hint at, the winner will control not just processing fees but the policy layer — spending limits, merchant restrictions, and dispute handling — through which autonomous purchasing is governed.
Stripe, for its part, is publishing the growth curve but not the totals. Until those absolute numbers surface, the 38-fold figure should be read as a directional signal: agentic commerce is small, but it is compounding quickly.
