Plaid: Meta's AI Shoppers Move Money Like Nothing It's Seen

By Daniel Rao · October 22, 2026

For two years, "agentic commerce" has been a slide in a pitch deck — the idea that your AI assistant would one day just buy things for you. On Wednesday's earnings call, Mark Zuckerberg announced that the future tense is over. More than a quarter of the people actively using Meta's AI agent, Muse, are already shopping through it, he said, and their average purchase is over $200. Then came the line that should make every payments executive sit up: "Plaid told us that they hadn't seen activity like they're seeing with their connector on any other service before." Plaid is the plumbing behind half the fintech industry. It has seen everything. It has not, apparently, seen this.

The numbers, read carefully, are startling. In just six weeks since its early-September launch, more than 10 million people in the US and Canada have set up Muse agents, Zuckerberg said — Sensor Tower's independent estimates, published the day before the call, put it at 10.2 million US downloads in the first 40 days, making Muse only the twelfth app ever to cross 10 million US downloads that fast. About 25 per cent of the people who set it up use it on any given day, more than double Threads' retention at a comparable stage. And then the commerce figure: "The most common use case for Muse is shopping. With more than 25% of people who are using Muse engaging in this with an average purchase size of over $200."

We pulled the Motley Fool transcript of the earnings call and compared Zuckerberg's exact phrasing against the simplified versions now circulating online, and the distinction matters: it is more than a quarter of engaged users, not a quarter of all 10 million sign-ups. Several outlets have blurred that line. The precise figure is impressive enough without the blur — a $200 average ticket means people aren't asking the agent to order pizza. They're trusting it with real money, on purchases that look a lot like considered retail.

Update, Oct. 23: Muse goes global — Japan first

Two days after the earnings call, Meta took Muse international for the first time. On 23 October, Meta launched its personal AI agent Muse in Japan — its first market outside North America, Kyodo News reported. Users give instructions by text or voice through a dedicated smartphone app, with basic features free; Meta's Japan unit says connecting Muse to Gmail and Google Calendar lets it summarise unread emails and manage schedules, and integrations with the flea-market giant Mercari and personal-finance app Money Forward ME are coming soon. On the trust question, Meta is explicit: Muse seeks users' approval before sending emails or making purchases, and cannot see users' passwords or card details. Meanwhile the checkout-rail war keeps escalating: Shopify confirmed on 21 October that it is opening Shop Pay to agents for stores that are not on Shopify — the first time its checkout works off-Shopify — directly widening the 'three labs, one checkout' surface this article describes. And the resistance is widening too: the pattern is now broad enough that platform blockers — Amazon, JPMorgan Chase, Charles Schwab, Delta, United, Cloudflare's default agent block on ad-supported sites — are being tracked as a movement, not isolated incidents.

The plumbing is already groaning

The most telling detail of the call wasn't a number at all. It was an anecdote about infrastructure buckling. "In the first week, we had to work with Stripe to raise credit limits since the volumes were above what any of us expected," Zuckerberg said. Read that again: within seven days of launch, the transaction volume flowing through an AI agent's shopping feature exceeded what Meta and Stripe had modelled. Somebody's spreadsheet was wrong, and it was wrong in the direction that matters.

Muse routes its agentic shopping through a connector from Plaid, the fintech company that links payment apps to customers' bank accounts. Plaid's business is watching money move; its connector powers thousands of services. For Plaid to tell Meta it had never seen activity like this on any other service is the kind of third-party validation startups would kill for — and it landed, almost as an aside, in the middle of an earnings call. Zuckerberg framed the productivity uses — connecting the agent to email and calendars — as evidence that users trust Muse's security setup, which runs on what Meta calls a Secure VM, with a forthcoming "Confidential VM" that he says will prevent even Meta from seeing users' content. Whether users should extend that trust is a separate question, and we'll come to it.

Three labs, one checkout

Here's what makes this week genuinely historic rather than just a good earnings call: three AI labs launched shopping-capable agents within 53 days of each other, and they're all converging on the same commercial rails. Anthropic opened its Claude Duet research preview the very same day — October 21 — a proactive agent for US subscribers that makes purchases through Stripe Link and Shopify's Shop Pay, and pointedly "asks before it sends a message, makes a payment, signs a document, or deletes anything." OpenAI's Dots agents, unveiled at DevDay in late September for Pro and Business users, run on their own cloud computer with purchases gated behind user approval. Three philosophies — Muse free and frictionless, Duet cautious and permissioned, Dots expensive and gated — one shared bet: the agent becomes the storefront.

The rails matter more than the apps. Stripe Link, Shopify's Shop Pay, Plaid's connectors: the winners of agentic commerce may not be the labs at all, but the payment pipes every agent is forced to use. Shopify saw this coming — it opened checkout to browser-based AI agents in September and reported AI-driven traffic to its stores up eightfold year over year. Our September reporting on Shopify's agentic checkout bet called it the anti-Amazon play. A month later, the anti-Amazon play has 10 million users and a $200 average ticket.

The stores that said no

Not everyone is applauding. Amazon blocked Muse in September, citing security concerns — the agent, Amazon said, did not identify itself, appeared to hold customers' credentials with access to order history, and arrived without Meta asking. Adidas is blocking it too. And it's not just retailers: JPMorgan Chase, Bank of America and Charles Schwab are among the banks restricting outside agents from moving customer money. The resistance is rational. An agent that can spend $200 a transaction on your behalf, authenticated through connectors you barely understand, is a fraud department's nightmare — right up until it's also the channel your customers prefer.

This is the tension the next year of commerce will be fought over. Forrester principal analyst Kate Winick put the trust problem bluntly: "The more information Muse has, the more effective it can be, and overall trust in Meta remains low." She's right, and the numbers make her point uncomfortable: consumers, she noted, "almost expect to have their data mismanaged in exchange for a high level of connectivity and utility." Ten million sign-ups in six weeks for a Meta product, in the same month a New Mexico jury found the company deceived users about data privacy, suggests she has diagnosed the market exactly. People don't trust Meta. They're using Muse anyway.

What Meta wants Muse to become

Zuckerberg was explicit that this is the beginning of a monetisation story, not the end of a product story. "Now that Muse has clear product market fit, we are entering a new phase and a more operational phase that is focused on scaling it," he said. "We expect to grow Muse to serve billions of people." The plan: build commerce tools that let Meta charge businesses fees for transactions the agent facilitates — "We expect to make money from Muse by taking a small fee from transactions," as he put it at the Connect event — plus paid AI subscriptions for heavy users and enterprise offerings. Then the genuinely audacious claim: "The average revenue per American user for our existing family of apps users is several hundreds of dollars annually, and we expect that Muse will reach an even higher level over time due to the amount of commerce that we already see taking place." Read that as a declaration of intent: Meta believes one shopping agent will eventually be worth more per user than Facebook, Instagram, WhatsApp and Messenger combined.

The roadmap he sketched is pure science fiction wearing a product timeline: a "Muse network" where "your Muses can work with your friends' and your families'" agents, and buying something means "not just navigating to that business's website; it's talking to their agent." Muse arrives on Meta's smart glasses next month. "Having your personal superintelligence with you throughout the day will be the most important part of the experience," Zuckerberg said. "Billions of Muses in a network at scale will be able to get more done for people and businesses by working together." The compute bill for that vision is colossal — Muse is "very compute-intensive" today, though Zuckerberg expects 10x cost-efficiency gains within a year — which is presumably one reason Meta just minted voiceless shares to fund the buildout.

Meta Muse shopping: what we know

How does shopping through Muse actually work? You connect payment methods through Plaid's connector and, on Shopify stores, Shop Pay; the agent then completes purchases on your behalf. Meta takes no cut yet — the monetisation plan is transaction fees charged to businesses plus subscriptions for heavy users.

Is it safe to let an AI spend your money? Meta points to its Secure VM architecture and the forthcoming Confidential VM. The counter-evidence: Amazon and major banks are actively blocking or restricting agent transactions, and Meta's own history on data privacy — including a $25 billion New Mexico judgment this month — is the industry's worst. Trust the architecture, verify the company.

How does Muse compare to Claude Duet and OpenAI's Dots? All three shop; they differ on friction. Muse is free and already transacting at scale. Duet (launched the same day, US waitlist) requires explicit approval before any payment. Dots sits behind OpenAI's $100-plus Pro tier. The shared rails — Stripe, Shopify, Plaid — matter more than the brand on the app.

Is Muse available outside the US and Canada? Yes, since 23 October 2026: Meta launched Muse in Japan, its first market outside North America, with a dedicated smartphone app (text and voice), free basic features, and planned integrations with Mercari and Money Forward ME. No other countries announced yet.

Can AI agents check out on stores that aren't on Shopify? Since 21 October, Shopify has opened Shop Pay to agents for stores not on Shopify — the first time its checkout works off-platform. Combined with Muse's Plaid connector and Stripe Link, the three labs' shared checkout rails now reach well beyond each lab's own app.

Our read: the checkout wars have started

Strip away the earnings-call theatre and one fact remains, and it's the Plaid line. When the company that watches money move for a living says it has never seen anything like the volume an AI agent is pushing through its connector — six weeks after launch, with the agent available in only two countries — the debate about whether agentic commerce is real is over. What isn't over is who gets to be the checkout. Amazon and the banks are betting they can keep agents outside the walls; Shopify, Stripe and Plaid are betting the walls are coming down; and three labs are betting the agent itself is the new storefront. Zuckerberg's revenue-per-user boast sounds absurd until you do the arithmetic he did: a $200 average ticket, a quarter of engaged users shopping, fees on every transaction. The shoddy assumption in the room is that consumers will wait for perfect trust before handing agents their wallets. They won't — 10 million of them just proved it. The checkout wars have started, and the first battle was won by whoever made spending feel effortless, not whoever made it feel safe.
