Stripe agentic commerce spikes in September, Collison says

A podcast remark with no numbers attached

Stripe President John Collison says the company's agentic commerce business has hit an inflection point. He didn't share any figures to back that up. On an October 12 episode of Cheeky Pint, the podcast he hosts, he said activity from AI agents shopping and paying for people had started "going vertical" in September.12 His guests were Meta CEO Mark Zuckerberg and Meta's chief AI officer, Alexandr Wang. The comment came up while the three discussed Muse, Meta's personal AI assistant, and its ability to buy things when a user asks.15

Collison told his guests that Stripe built the tooling and made a series of announcements at its Sessions conference, and that the numbers only took off in September.15 He credited "computer use" with getting the market there. In his view, that ability of AI models to operate software interfaces was the last missing piece. Now a user can ask Muse to buy almost anything and the agent works out how to do it.15 Every outlet that covered the exchange agrees on one point: he gave no volume figures.111215

The accounts differ on a smaller detail. Collison's quote puts Sessions in May.15 Other reporting dates the event and its product launches to April, and one breakdown gives April 29, 2026.1219 The discrepancy doesn't change the story, but it shows how loosely the main claim was delivered.

What probably caused the September jump

The timing can be explained without Stripe's internal data. In September, Stripe announced that Meta had built its Link wallet into Muse, so the assistant can complete payments for users.18 That deal came after similar Link integrations with xAI's Grok and with Instinct, an assistant from Spear Street Technology.18 Meta says Muse can buy things without seeing the customer's underlying payment details.18

The likeliest explanation, in this analysis, is that Collison's "vertical" curve tracks a large consumer AI product going live on Stripe's wallet rather than a broad change in how people shop. Zuckerberg added one concrete observation on the podcast: many more businesses are asking Meta for deep integrations, and very few have tried to block the assistant.12 As one critique points out, though, integration requests and completed transactions are not the same thing. A merchant letting an agent read its catalog has not yet processed a real agent-made sale.12

That critique is the sharpest response so far. It doesn't call the claim false. It notes that Stripe sees more agent transaction data than anyone else, so Collison is describing a dashboard no outsider can check. A platform executive talking up his own growth on his own podcast is a meaningful signal, but it can't be verified.12

Building the full stack

Whatever the real volumes are, Stripe has built more for this market than any other company. It launched the Agentic Commerce Protocol (ACP) with OpenAI in September 2025 as an open standard for agents to check out with merchants.1 In December 2025 it added the Agentic Commerce Suite, a low-code product that lets merchants upload a catalog once and pick which AI agents can sell it.1 Early merchants included Etsy, Coach, Kate Spade, URBN, Ashley Furniture and Revolve. Wix, Squarespace, WooCommerce, BigCommerce and commercetools signed on as platform partners.28

At Sessions 2026, Stripe expanded the Suite to cover OpenAI, Microsoft, Meta and Google, which means merchants can sell inside Google AI Mode and the Gemini app.20 It also launched Link Wallets for Agents. Each task gets a one-time virtual card, the user approves each payment, and the agent never sees the real card details.20 A Stripe-backed analysis says the company announced 288 agentic-focused products at the event. A few months later Stripe agreed to buy OpenRouter, a gateway that routes AI model traffic, for $7.5 billion.12 That deal gives Stripe a view of the token traffic behind the agents themselves.12

Most of this rests on one security idea: the Shared Payment Token. It lets an agent start a payment with a buyer's saved payment method without seeing the credentials. Each token can be limited to one seller, a time window and a maximum amount.1 Stripe also extended its Radar fraud tools to watch for agent-specific behavior.4 For developers selling services rather than goods, Stripe and Tempo released the Machine Payments Protocol in March 2026 so agents can be billed per call over HTTP.19

Stripe is also getting partners to embed its checkout in their own agents. Product-discovery company Constructor launched an "Agentic Checkout" with Stripe. Shoppers using Constructor's AI Shopping Agent can pay with Link or other methods without leaving the conversation.17 This is where the personalization story turns into a payments story. A Stripe executive has said AI-assisted shopping on retailers' own sites converts about four times better than shopping without an agent, though that is a company figure.14

Shopping is growing faster than payments

The main reason for skepticism is that much of the industry says agents are helping people shop much more than they are paying. At a Goldman Sachs conference in September, Visa CEO Ryan McInerney said consumers use AI assistants to compare and choose, then go to the seller's website to pay. Visa sees adoption for shopping, he said, but not yet for autonomous payments.26

Stripe has a setback of its own here. Its first big consumer launch, Instant Checkout inside ChatGPT, was pulled back in March 2026. OpenAI said the first version wasn't flexible enough and moved toward product discovery and checkout run by merchants.29 One account says sales from the roughly dozen Shopify merchants that went live were close to zero.12 The protocol still exists, refocused on larger retailers, but the part where money actually changed hands didn't last.12

Other numbers point both ways. BrightEdge estimates purchases through agents are growing 43% a month and have roughly quadrupled since April. It also found that only about 3% of the e-commerce companies it works with let agents complete transactions.30 Another estimate says only 11% of small and mid-size businesses qualify as agent-ready. The same source says 93% of merchants think the AI provider should cover losses from wrong purchases.20 Consumers have doubts too. One report says 72% won't give AI their card details, which is the problem Stripe's tokenized wallet is meant to solve.14

Liability is still unresolved

Who pays when an agent buys the wrong thing remains an open question. As things stand, the merchant does. Every published protocol, including Stripe's ACP, Google's UCP, Visa's Trusted Agent Protocol and Mastercard's Agent Pay, keeps the merchant as merchant of record. Neither Visa nor Mastercard has published a liability rule or chargeback reason code for agent-initiated transactions.26 EMVCo released a draft framework on September 1 proposing a shared record of consumer intent, but it is only a draft.26 Federal Reserve Governor Christopher Waller has described the change this way: the question is no longer whether a buyer is authorized to pay, but whether an agent has the authority to pay for that buyer.30

Retailers are taking different approaches. Amazon blocks prominent outside agents, Target allows approved providers, and Walmart is working with AI companies directly.30 eBay banned third-party "buy-for-me" agents from placing orders in February.29 Some retailers are building their own assistants rather than handing discovery to outside platforms. Best Buy and Kohl's have launched their own, and Anthropic has released templates for retailers to build shopping agents. Those templates deliberately leave payment to existing checkouts.22

Several standards, with Stripe in most of them

The protocol landscape is crowded. One count lists eight protocols now live in agentic commerce.16 The most direct rival to Stripe's ACP is the Universal Commerce Protocol developed by Shopify and Google. Stripe is listed as a backer of both.16 Visa has partnered with OpenAI, and Mastercard has named Braintree and Checkout.com as its first Agent Pay acquirers.2426 Stripe also appears on Visa's Trusted Agent Protocol partner list and among American Express's launch partners for its agent purchase-protection program.2426

This explains Stripe's overall approach. One payments consultant says the agent and the wallet may eventually become the same thing.18 Stripe has mostly served merchants, not consumers. Putting Link inside the assistants people talk to gives it a direct consumer relationship, and Link would compete with Apple Pay and browser autofill for the role of default card on file.18

Our take

The September surge is probably real. The infrastructure is in place, and the Muse integration gives a plausible reason for a sudden jump. But Stripe is measuring "vertical" from a small base, in a market where a Visa CEO says autonomous payments haven't caught on, where most merchants don't allow agent checkout, and where nobody has settled who is liable for mistakes. Stripe has built the most complete toolkit and backed every competing standard, so it is well placed whichever one wins. Whether agents become a real payments channel won't be settled by a podcast remark. It will depend on Stripe publishing transaction numbers, and on card networks writing the chargeback rules that agent purchases still lack.
