Shopify already has it. > Amazon locked Meta's agent out over credential capture. A day later Shopify opened Shop Pay, a checkout whose design keeps payment details on file, and nobody has disclosed the take-rate. [Amazon's door slammed shut](https://theinference.org/article/america-s-no-1-app-is-banned-from-america-s-biggest-store) on Sunday 20 September. Muse users shopping the site [began hitting a popup](https://www.theverge.com/tech/998078/amazon-blocks-meta-muse-ai-agent-shopping): "continued access by an unauthorized AI agent violates [Amazon](https://theinference.org/markets/companies/amazon)'s Conditions of Use, to which our customers have agreed." [1] Amazon's stated grounds: the agent browses without identifying itself, "appears to capture and store customer credentials," and scrapes account data. [1] [2] Its rules bar autonomous agents unless they identify themselves as agents and stop imitating humans. [3] [Meta's reply](https://finance.yahoo.com/markets/stocks/articles/amazon-gains-while-closing-store-131729087.html): Muse requires user approval before it buys, cannot access stored payment credentials, and pays with one-time cards through Stripe's Link. [4] ## The stakes behind the popup Amazon is defending the checkout behind $116.2 billion in second-quarter North American sales and $9.1 billion in operating income. [4] The next session repriced the other camp: [Shopify](https://theinference.org/markets/companies/shopify) closed up 7.3% at $137.92 on the deal, [Meta](https://theinference.org/markets/companies/meta) up 11.43% at $741.24 on Muse momentum. [5] Merchants did not queue for this: every eligible US store went live in agent channels by default, no setup required. [6] ## The open door is a vault The sanctioned lane is built on Shop Pay, whose [stated design](https://finance.yahoo.com/technology/ai/articles/shopify-partners-meta-muse-ai-115807895.html) "retains customers' payment and delivery details." [5] Shopify's vice president of product Rohit Mishra says agents transact on the buyer's credentials, "vetted and stored on file," each limited to a single purchase so the card number is never exposed. [7] Who pays here: the merchant, enrolled by default under terms neither company has disclosed, and the shopper, whose card now sits in the agent lane by a consent wrapper. [6] [9] The fight was never about whether your card sits on file; it is about who collects the fee for holding it. ## What is priced and what is not Deutsche Bank read the deal as AI platforms defaulting to Shopify's rails, calming investor fears of disruption. [5] [Evercore](https://theinference.org/markets/companies/evercore)'s Mark Mahaney sized the demand: 1% of Meta's 3.6 billion users paying $20 a month is roughly $8 billion, with transaction revenue share on his list of ways to monetize. [8] *Chart: **At 13 days old, Muse trails only ChatGPT** Bar chart of cumulative downloads in each app's first 13 days after launch: ChatGPT 3.1 million, Muse 2.5 million, Claude 0.4 million, Grok 0.2 million* *Cumulative downloads in each app's first 13 days after launch, in millions; Sensor Tower data reported 21 September 2026; staggered iOS and Android release dates affect totals. [2]* ## The number nobody has disclosed The take-rate is the missing number. No revenue split, no rollout timetable has been disclosed. [9] The counterweight is friction: a [9 September test of the Link path](https://finance.yahoo.com/technology/ai/articles/shopify-embraces-meta-muse-across-113401279.html) failed three basic errands, one of which took under 30 seconds by hand. [6] Barron's calls the Meta bump one to enjoy while it lasts, with chip stocks the safer AI bet. [10] Zuckerberg promised "more partnerships like this coming soon." [5] The next one needs a number attached. ## Takeaway The agentic checkout fight is not about whether your card sits on file but who collects the fee for holding it. Amazon shut Muse out; Shopify let it in, and neither company will say what the take-rate is. ## Sources 1.
