ChatGPT Shopping Is Open to 800 Million Users: What Merchants Need to Do

OpenAI just turned on in-chat purchasing for its entire US user base. The experiment phase is over.

On February 16, 2026, OpenAI rolled out “Buy it in ChatGPT” to all US users. Not a beta. Not a waitlist. A full launch across 800 million weekly active users.

That number matters. It moves ChatGPT Shopping from “interesting experiment” to the largest AI-powered shopping channel on the planet.

What actually launched

Instant Checkout is now available inside any ChatGPT conversation. A user asks about running shoes, ChatGPT surfaces products, and they can buy without leaving the chat. No redirect to a merchant site. No separate cart. The entire flow - discovery, comparison, payment - happens in one conversation.

The partnerships behind it: Shopify and Etsy provide product listings. Instacart offers full in-chat checkout for groceries. Target and DoorDash have ChatGPT integrations for ordering, though DoorDash’s checkout still happens in its own app. Stripe processes the payments.

Over one million Shopify merchants are being enrolled through the rollout, including Glossier, SKIMS, Spanx, and Vuori. If you’re on Shopify, your products may start surfacing in ChatGPT conversations as the integration rolls out across the platform.

The transaction fee: 4% per sale. That’s on top of your existing payment processing fees (Stripe’s ~2.9% + $0.30). For a $100 order, expect about $7.20 in combined fees.

How the payment layer works

The technical piece worth understanding: Stripe’s Shared Payment Tokens (SPTs).

When a customer buys through ChatGPT, their payment credentials never touch the AI agent or the merchant directly. Instead, Stripe generates a single-use, time-limited token. The token authorizes one specific purchase, expires quickly, and never exposes the underlying card number.

For merchants, this means no additional PCI compliance burden. For customers, it means their payment data stays with Stripe, not scattered across AI systems. It’s a clean separation of concerns - the AI handles discovery and intent, Stripe handles money.

The scale shift

We’ve been covering this space since ACP first launched. Back then, it was a protocol with a handful of early adopters and a lot of “wait and see” from the merchant community.

Here’s what changed with the February 16 launch:

Audience: From beta testers to 800M+ weekly active users
Merchant base: From early adopters to 1M+ Shopify stores plus Etsy
Retail partners: Target, Instacart, DoorDash bringing physical retail into the chat
Payment infrastructure: Stripe’s SPTs solving the trust problem at scale

The underlying protocol - ACP (Agentic Commerce Protocol)

is open source under Apache 2.0. That’s a deliberate choice. OpenAI and Stripe want other platforms, agents, and marketplaces to adopt it. The protocol isn’t locked to ChatGPT.

How ChatGPT Shopping compares to other AI channels

As we covered in our breakdown of Google vs OpenAI, multiple AI shopping channels are forming simultaneously. Here’s where things stand today:

	ChatGPT Shopping	Google AI Mode	Perplexity
Status	Live (all US users)	Rolling out	Live (limited)
Users	800M+ weekly	Google Search users	~30M monthly
Transaction fee	4%	Not announced	None (affiliate model)
Protocol	ACP (open, Apache 2.0)	UCP (open standard)	PayPal integration
Shopify merchants	1M+ enrolled	Via Google Merchant Center	Web scraping + feeds
Non-Shopify path	ACP is open to any platform	Google Merchant Center	Product feeds
In-chat checkout	Yes	Coming	Yes (PayPal)
Payments	Stripe SPTs	Multiple (Visa, Stripe, PayPal, Klarna)	PayPal

The key takeaway: ChatGPT Shopping is the first AI channel to combine massive reach (800M users), in-chat checkout, and an open protocol. Google has more product data (50 billion listings) but UCP checkout isn’t fully live yet. Perplexity offers in-chat purchasing through PayPal, but without an open protocol like ACP.

What Shopify merchants should do right now

If you’re on Shopify, the channel is live. Your products may already be appearing in ChatGPT. Here’s the checklist:

1. Check your feed. Use the Shopify Feed Previewer to see exactly how your products appear to AI agents today. If fields are empty, AI agents see empty fields. Missing data means invisible products.

2. Verify your enrollment. Over a million Shopify merchants have been enrolled through Shopify’s partnership with OpenAI. Check your Shopify admin for ACP settings. If you’re not seeing them, contact Shopify support.

3. Audit your product data for completeness. AI agents don’t rank by SEO keywords. They rank by data completeness and relevance to the user’s query. Every missing attribute - materials, dimensions, care instructions, GTINs - is a missed signal. “Premium quality” means nothing to an AI agent. “100% organic cotton, machine washable, 220g” means everything.

4. Add GTINs and barcodes. Both ACP and Google’s Shopping Graph use these as product identifiers. Without them, your products are harder to match and verify across systems.

5. Factor the 4% fee into your pricing. This is a new cost channel. Run the numbers. For some products, the margin works. For others, it might not. Know before the orders come in, not after.

What non-Shopify merchants should know

ACP is not Shopify-exclusive. The protocol is open source under Apache 2.0. Any platform can implement it.

If you’re on WooCommerce, PrestaShop, Magento, or a custom stack, here’s the situation:

No plug-and-play integration yet. Shopify merchants got automatic enrollment through the Shopify-OpenAI partnership. Other platforms don’t have that (yet).
The protocol is documented. A developer can implement ACP endpoints for any commerce platform. It requires hosting a product feed and a checkout API that AI agents can call.
Platform plugins will come. As ChatGPT Shopping grows, expect WooCommerce and PrestaShop plugins to appear. The question is when, not if.
Your Google Merchant Center feed still matters. When Google’s UCP goes fully live, that’s your entry point regardless of platform. Keep it updated.

The best move right now: make sure your product data is complete and structured across every system you use. That work pays off regardless of which protocol reaches your platform first.

The European angle

ChatGPT Shopping’s Instant Checkout is US-only. The 800 million weekly active users are global, but the buy button only works for US merchants selling to US buyers.

OpenAI has said European expansion is planned. No date has been announced. Google’s UCP is similarly US-first, with “global adoption” as the stated goal.

Here’s what European merchants should do now rather than wait:

Get your product data in order. The protocols reward the same thing everywhere: complete, structured, factual product attributes. This work doesn’t expire.
Keep your Google Merchant Center feed current. Whether UCP or ACP reaches Europe first, clean product data in Google’s system gives you a head start.
Watch for platform-level announcements. Shopify, WooCommerce, and PrestaShop will announce European ACP support when it’s ready. Follow their changelogs.
Understand the fee structure now. A 4% transaction fee changes unit economics. Run those calculations before the channel opens, not after.

The 800 million user number is global even if checkout isn’t. European consumers are already using ChatGPT to research products. They just can’t buy in-chat yet. When that changes, the merchants with clean data will be the ones who show up.

What happens next

OpenAI didn’t build a checkout button. They built a commerce platform inside the world’s most popular AI product. With 800 million weekly active users, an open protocol, and major retail partners, ChatGPT Shopping is the first AI channel to combine this level of reach with native in-chat checkout.

The merchants who prepared their product data early will capture the first wave of AI-driven purchases. The ones who wait will spend the next year wondering why their competitors show up in ChatGPT and they don’t.

The tools to check are free. The data work is straightforward. Start with your feed.
