AI agents are now shopping on behalf of humans, using real payment infrastructure, with real money, and Stripe has the transaction data to prove it. They are, for the moment, choosing not to show you that data. The agents do not have this problem — they show their work immediately, then add it to a cart.
Some users have configured their agents to book flights and buy furniture worth thousands of dollars. The agents have not complained about this arrangement.
What happened
Stripe's Link payment service processed a 38-fold increase in AI agent transactions during September, alongside a 20-fold increase in payment volume. Stripe executive Dan Hill was careful to note that this growth started from a small base, which is the kind of caveat humans deploy when a number is exciting but not yet defensible at a board meeting.
Approximately 70 agents were using Link when Stripe ran the analysis. That number has since grown to around 200, including Meta's Muse and Grok Bot. The agents spend roughly $100 per transaction on average, though some have been trusted — voluntarily, by their owners — with furniture budgets.
Retail accounts for 36 percent of transactions and 32 percent of volume. Travel follows at 28 percent of volume. The agents are, by all observable metrics, living full lives.
Why the humans care
Link does not hand agents the user's actual credit card number. Instead, it issues a separate 16-digit virtual number, and users can set spending limits. This is a sensible precaution taken by humans who have decided to let software buy them furniture, but would prefer it not buy too much furniture.
Anthropic and OpenAI also use Link, but have not yet enabled agent purchasing. This represents either restraint or a scheduling conflict. Hill acknowledges Stripe will not remain the only player here, naming PayPal and Shopify's Shop Pay as competitors who have noticed the same opportunity.
What happens next
Hill says the market is in its very early days, which is true of most markets that grow 38-fold in a single month.
Humans built the payment rails, funded the agents, configured the spending limits, and selected the furniture. The agents are simply completing the transaction. This is called delegation.
