Retailers split three ways over who handles checkout in Meta's Muse agent

Meta's case for Muse as a store rests so far on a spokesperson's statement that shopping has quickly become one of the agent's biggest usage drivers ^[1], and on the app reaching the top of Apple's free iPhone chart ^[17]. Both measure attention. Revenue depends on a narrower step. A shopper who taps the checkout button inside Muse gets an approval card with the order details ^[3], pays through Stripe's Link or Shopify's Shop Pay ^[4], and Meta takes a small fee on the transaction, Mark Zuckerberg said at Meta Connect ^[7]. Clicking a listing can also open straight to the retailer's own website ^[2], and I'd expect the split between those two paths to decide how much of Muse's shopping traffic becomes Meta revenue. CNBC's report does not give the fee rate, the payment partners' share or a count of orders ^[7]. The retailers have already chosen different paths. Walmart, Gap, Sephora, Expedia, Wayfair and Best Buy were named in the Sept. 23 slate Meta billed as an "official fast lane" for the agent, though not every connector is live ^{[8] [9]}. Ticketmaster, also in that slate, sends Muse users to its own marketplace to pay ^[10]. "Fans remain in complete control of their purchase decisions, as final purchases are all made within Ticketmaster's secure marketplace," a Ticketmaster spokesperson told CNBC ^[11]. Amazon blocked Muse from buying on its site, saying the agent breaks its terms of service and alleging that it stores customer credentials and scrapes account data ^[12]. Each choice gives something up. Amazon forgoes whatever orders Muse would have sent it and keeps shopper logins away from Meta's agent ^[12]. Ticketmaster takes the referrals and keeps the payment; of the eight partners the report names, it is the only one described as holding payment on its own site ^[1]. The connector retailers accept Meta inside the order. Meta, for its part, runs checkout on other companies' rails: two of the three payment providers it has named are live, with PayPal still pending ^[2], and Link "generates a one-time-use card so your real card details stay hidden," according to Meta ^[5]. "The real fight over Muse is between companies, and the consumer is the prize," Luca Cian, a professor at the University of Virginia's Darden School of Business, told CNBC. "Whoever owns the agent owns the relationship with the shopper, and every retailer knows it." ^[13] I think he has the direction right. The evidence on size so far is one spokesperson's usage claim ^[1]. The money can go one of three ways from here. Muse could stay mostly a referral engine, with shoppers clicking through to retailer sites and the fee touching a minority of orders. The approval card could become the default checkout, making Meta's fee a cost connector retailers build into their margins. Or Amazon's credential objections could spread to other large sellers, leaving the connector slate to retailers who need traffic more than they need the customer record. In my view Meta is building toward the second, since the approval card and the one-time card both give a shopper reasons to finish inside Muse ^{[3] [5]}. That view is wrong if the connector partners copy Ticketmaster and move payment to their own sites ^[10]. Shoppers can tell Muse exactly which brand, price and availability they want ^[19], and the agent scans retail sites for matches ^[2], so each retailer's price sits next to its rivals'. In a January Morning Consult survey, 59% of U.S. adults called price-gouging a "major concern" with AI-driven dynamic pricing ^[14]. Walmart CEO John Furner wrote in an open letter last week that the company does not use shoppers' personal information for dynamic pricing, and said he had "heard concerns about companies using that information and technology to charge you more" ^[16]. Instacart, a Muse partner, ended its AI pricing tests late last year amid pushback ^[15].
