In six weeks, a personal AI agent from Meta went from launch to more than 10 million users, and shopping became its most common use, with average purchases above US$200, according to CEO Mark Zuckerberg on the company’s third-quarter earnings call [8]. In the same stretch, Amazon cut that agent off from Amazon.com [6]. And one of the first mass-market attempts at buying inside a chatbot, OpenAI’s Instant Checkout, had already been scaled back after about five months [13].
For Jamaican and wider Caribbean brands, the lesson is not that one platform has won. It is that the rules of the shopping moment are being written now, by companies with very different commercial interests. The brands that understand those differences, and the Caribbean-specific gaps in each, will have choices. The rest will inherit whatever the platforms decide.
Three giants, three different bets
| Player | The bet | Where it is live | Takeaway for brands |
| Open protocol (Universal Commerce Protocol) with checkout inside AI Mode and Gemini; retailer stays seller of record [1][16] | Eligible products in the US, Canada and Australia; select, participating merchants [1] | Feed quality in Merchant Center is the entry ticket [1] | |
| Amazon | Its own agents (Alexa for Shopping, Buy for Me); outside agents blocked [6][12] | Amazon.com; Alexa for Shopping used by 400M+ customers in the past year, per CEO Andy Jassy [7] | Visibility is inside Amazon’s ad-funded system [12] |
| Meta | Muse, a personal agent that shops across the open web; Meta plans to take a fee from businesses on purchases [8] | US and Canada; 10M+ users six weeks in [8][10] | Shopify and Walmart are connected; Amazon is not [9][11] |
| OpenAI | Retreated from in-chat checkout in March 2026; ChatGPT now focuses on discovery [13] | Merchants’ own checkout or retailer apps [13] | Platform bets can reverse in months [13] |
Google is building around an open standard. Its Universal Commerce Protocol lets shoppers buy from eligible product listings inside AI Mode in Search and the Gemini app, using Google Pay, while the merchant remains the seller of record [1][16]. Participation runs through Merchant Center product data, and Google says the checkout feature currently applies to products eligible in the United States, Canada and Australia, for participating merchants [1]. For some Shopify stores, Google has begun enabling the checkout automatically, with an option to opt out; those merchants must be based in the US and sell to US customers [14].
Amazon wants agentic shopping to happen inside its own walls. On 20 September it blocked Meta’s Muse from shopping on Amazon.com, saying Meta had not told it Muse would access the store, that the agent does not identify itself while browsing, and that it appears to capture and store customer credentials [6]. Amazon’s own agent, Alexa for Shopping, was used by more than 400 million customers in the past year, and US users spend 50 per cent more per order than non-users, Jassy said on the 29 October earnings call. He also said external agents are not meaningfully affecting Amazon Ads, because relatively few people shop that way [7]. Total Retail notes that a third-party agent can bypass sponsored products, and that Amazon earned more than US$68 billion in advertising revenue last year [12].
Meta is taking the opposite route. Muse is a personal agent that connects to a user’s email, calendar, payments and shopping services, and where a service has no programming interface it can use the site through a browser, much as a person would [6]. Meta says it will keep Muse free for most users and take a percentage of commerce on the platform, with businesses paying the fee [8][9]. Walmart has embraced the agent [11]; Meta has also linked Muse to Shopify for small sellers [9].
OpenAI is the cautionary tale. Instant Checkout launched in September 2025, but by March 2026 the company had moved purchases to merchants’ own checkouts and retailer apps and said it would prioritise product discovery. Shopify’s president said only about a dozen Shopify merchants were using it, as reported by TechRound citing The Information and Search Engine Land [13].
The Caribbean reality check
The Caribbean has an audience for all of this. DataReportal counted 2.54 million internet users in Jamaica in October 2025 and 1.81 million social media user identities [4]; NapoleonCat’s Meta-sourced estimates put Facebook alone at about 1.72 million Jamaican users in February 2026 [5]. But the infrastructure around those shoppers has gaps that matter to an agent.
- Google’s shopping feeds do not list Jamaica. Google’s Merchant Center table of supported Shopping ads and free-listing countries, checked on 2 November 2026, does not include Jamaica or any other Caribbean country [2]. That table governs the feeds behind Google’s shopping surfaces; it does not mean a Jamaican business cannot be mentioned by an AI answer, but it does mean the structured route is not open in the usual way.
- Muse is a US and Canada product for now. Meta’s figures cover users in the US and Canada, and Zuckerberg said Muse is very compute-intensive to run [8][10].
- The payments rails are a hurdle. Stripe, whose technology underpins Muse’s checkout, does not list Jamaica among its supported countries; it offers Atlas, a service for incorporating a US company, as the route for businesses elsewhere [3]. The Gleaner reported in 2024 that PayPal was still largely absent from Jamaica for linking with local bank accounts [15], and Businessuite has not re-verified that status for this article.
In practical terms, the first Caribbean brands to meet an AI shopper are likely to be those selling to the diaspora in the US and Canada, where the agents and checkouts are actually live, or those already on platforms such as Shopify that sit between the merchant and several agents at once.
Five questions every Caribbean marketer must now answer
1. Can an agent find us, read us and trust us?
Agents cannot buy what they cannot parse. Google’s checkout depends on structured product data in Merchant Center [1], and a browser-driven agent like Muse reads pages as a person would [6]. Possible answer: make prices, sizes, stock and delivery terms available as plain text on the brand’s own site, not only in images, PDFs or social posts, and keep them consistent across the website, Google Business Profile and social pages. This is Businessuite’s reading of how the systems work, not a published platform requirement.
2. Where do we want to appear, and on whose terms?
Amazon blocks outside agents while Walmart welcomes them [11][12], and Shopify lets merchants switch off Google’s direct checkout while remaining discoverable [14]. Access is now a policy choice. Possible answer: decide, brand by brand, which agents may browse and buy, set that in the site’s terms and technical controls, and review it quarterly.
3. Who owns the customer after the sale?
Under Google’s model the retailer stays the seller of record, handling settlement and post-purchase [16]. Meta intends to take a cut of purchases [8]. Possible answer: keep order data, service and loyalty in the brand’s own hands, and treat the agent as a sales channel rather than the relationship.
4. How will we take payment and get paid?
Several agent checkouts assume US-style payment accounts [3][14]. Possible answer: map the options with a banker and an adviser before a platform asks. Local gateways, a US entity for diaspora sales, or selling through an established marketplace each carry legal, tax and cost consequences that should be checked professionally.
5. What does advertising mean when software chooses?
Google is adding ad formats to AI Mode and has expanded Shopping campaigns with AI Max, while Amazon has made Sponsored Prompts in its assistant billable per click [20]. Muse, by contrast, earns from transaction fees [8]. Possible answer: keep funding the paid channels that still work, but add a monthly check of how each major assistant describes and recommends the brand, and track visits and sales that arrive from AI referrals.
Top priorities for the brands you manage
- Clean the product data. One accurate, text-based source of truth for prices, availability and delivery.
- Choose your ecosystems deliberately. Do not bet on one. The OpenAI reversal and the Amazon block show how quickly the ground moves [6][13].
- Sort out payments first. Without a payment route, agent access is academic [3].
- Start with the diaspora. The US and Canada are where checkout and agents are live [1][8].
- Protect the customer relationship. Own the data, the service and the loyalty programme.
- Measure what the assistants say. Review how AI tools describe your brand, and fix the sources they rely on.
A note of caution
This is early. Jassy argues agent shopping is a small share of Amazon’s volume [7], one trade report says checkout inside AI tools is still mostly a US offer [19], and Meta’s Muse faced security and reliability questions before launch [6]. The practical stance for Caribbean brands is preparation without panic: make the data and the payments ready, and let the platforms show where the customers actually are.
