Goodbye 28 Tabs: ChatGPT Instant Checkout Just Made Online Shopping Seamless

Key Takeaways

• OpenAI launched ChatGPT Instant Checkout on Sept. 29, 2025, letting U.S. users buy directly in ChatGPT without leaving the app.
• The system is powered by the Agentic Commerce Protocol (ACP), co-developed with Stripe, designed to make AI-driven transactions secure and merchant-controlled.
• At launch, purchases work with Etsy sellers. Shopify merchants (including Glossier, SKIMS, Spanx, and Vuori) are coming soon.
• 700M people use ChatGPT weekly, making this a massive new distribution channel for businesses.
• For shoppers, it means fewer steps: Search, compare, and buy in one conversation.
• For businesses, it’s a visibility test: If you’re not showing up in AI’s curated product recommendations, you’re effectively invisible at the point of sale.

Here’s how product discovery worked for the last two decades: You searched for “comfy athletic shorts”, and Google showed you 20+ options. You opened eight tabs. You compared features, read reviews, and checked prices across sites. You made a decision based on your own research and judgment.

The shopper controlled the consideration set. The shopper did the comparison. The shopper decided which brands even deserved attention.

That era is dead, and we’ve entered the agentic shopping era. This Monday, OpenAI announced that 700 million weekly ChatGPT users can now buy products without leaving the chat interface.

No more 28 tabs of reviews and Reddit threads about shorts. ChatGPT will surface three to five highly tailored, pre-filtered recommendations ranked by what it considers relevant.

No pagination. No “see more results.” Just the AI’s top curated picks. And if a product supports Instant Checkout, users can tap “Buy,” confirm their order, and complete the purchase without ever leaving the chat.

Translation for online retailers: If your product isn’t in ChatGPT’s top handful of recommendations, you don’t just rank lower. You literally don’t exist in that purchase journey.

What is ChatGPT Instant Checkout, and how does it work?

ChatGPT Instant Checkout is OpenAI’s new feature that lets people buy products directly inside ChatGPT without leaving the app. It’s powered by the Agentic Commerce Protocol (ACP), an open standard co-developed with Stripe that allows AI agents, merchants, and customers to securely complete transactions.

At launch, U.S. users can shop from Etsy sellers, with more than a million Shopify merchants, including Glossier, SKIMS, Spanx, and Vuori, rolling out soon. For now, Instant Checkout supports single-item purchases, with multi-item carts and expanded merchant availability on the roadmap.

Here’s how it works in practice:

1. A user asks a shopping query in ChatGPT, like “best running shoes under $100.”
2. ChatGPT surfaces relevant, unsponsored product recommendations ranked by relevance.
3. If a product supports Instant Checkout, the user can tap “Buy,” confirm order, shipping, and payment details, and finish the purchase, all without leaving ChatGPT.
4. Merchants process the order through their existing systems, keeping control of payments, fulfillment, and customer relationships.

Why ChatGPT Instant Checkout is a huge win for consumers

Let’s acknowledge what OpenAI got right: This is genuinely more convenient for shoppers.

Think about the traditional ecommerce experience: Research on one platform, click through to multiple merchant sites, re-enter payment information, manage different shipping notifications, track orders across various systems. It’s friction at every step (hence the 28 tabs open on our browser during those late-night shopping binges).

ChatGPT Instant Checkout compresses the whole experience: Research, analysis…all of that. You’re already in the app asking questions. The AI understands context from your conversations. You can buy without context-switching. For consumers, this is a meaningful improvement.

I’ve shared this example before of how much better ChatGPT is at providing simple book recommendations compared to traditional search. Why? It already knows what I like and what we’ve chatted about in the past.

And unlike Google Search, which primarily surfaces what’s been optimized for search engines, ChatGPT can handle nuanced requests that traditional search struggles with:

• “Find unique end tables under $200 from local Seattle retailers”
• “Show me sustainable activewear brands with good labor practices”
• “I need wireless headphones that work well for phone calls, not just music”

The AI can carry context forward from all your conversations. If you told ChatGPT last week that you prefer minimal packaging and have wide feet, it can factor that into today’s shoe recommendations. Ultimately, it starts the ecommerce funnel with a shopping assistant instead of a search engine.

Imagine this scenario: You’re planning a camping trip. Over several conversations, you’ve discussed the location (Pacific Northwest), the season (October), your experience level (beginner), and your budget constraints. When you finally ask “what tent should I buy?”, ChatGPT doesn’t just surface generic “best tents” results. It recommends 3-season tents suitable for PNW weather, priced within your stated budget, from brands that align with preferences you’ve mentioned across weeks of conversations.

That’s genuinely useful. That’s personalization that goes beyond what cookies and browsing history can accomplish. It also presents an opportunity to buy things directly from ecommerce websites vs. through a platform like Amazon.

Amazon often wins because of the familiar UX and quick shipping. A helpful part of how the Agentic Commerce Protocol works is that it generates transactions directly through a brand’s website. You pay a fee to ChatGPT but avoid Amazon’s marketplace fees (which can reach 15-20% with FBA) and the intense competition of hundreds of sellers offering similar products.

You also get exposure to a huge, fast-growing audience.

According to Similarweb data reported by Modern Retail, ChatGPT already drives:

• 20% of Walmart’s referral traffic (up from 15% just one month prior)
• More than 20% of Etsy’s referral clicks
• 15% of Target’s referral traffic
• 10% of eBay’s incoming traffic

While referral traffic still represents less than 5% of these retailers’ total visits today, that percentage is growing every single month. Working with hundreds of businesses at WebFX, we’ve seen this pattern before: New discovery channels start small, grow exponentially, then become indispensable before most companies even develop a strategy.

So lots of excitement and genuine wins for consumers. But this personal shopping assistant comes with some big asterisks and signals that more commercialization is coming to ChatGPT.

The invisible gatekeeper problem (and why transparent ChatGPT ads are coming soon)

OpenAI states that “product results are organic and unsponsored, ranked purely on relevance to the user,” and that Instant Checkout availability “does not influence product ranking in search results”.

That’s the official line. But here’s where it gets complicated:

When ranking multiple merchants selling the same product, ChatGPT considers factors like “availability, price, quality, whether a merchant is the primary seller, and whether Instant Checkout is enabled” to optimize user experience.

Notice that last factor? Whether Instant Checkout is enabled does influence ranking when comparing merchants. OpenAI is now directly incentivized to surface products from merchants who’ve enabled Instant Checkout…because that’s how they generate revenue.

Ultimately, this is another clear step towards ChatGPT offering native ads on the platform. The reality is that clearly labeled ads might actually be better for everyone than “organic” results with hidden commercial incentives showing up in ChatGPT.

Think about it from the user perspective:

Scenario A (Traditional Ads): You see three organic results, then two clearly marked “Sponsored” listings. You know exactly which recommendations might be influenced by payment.

Scenario B (Current Model): You see five “organic” results, but you have no idea that OpenAI makes money when you buy from some of them and not others. The financial incentives are completely invisible.

Which creates more trust?

From a marketer’s perspective, transparent advertising also makes more sense. If I’m going to pay to appear in ChatGPT recommendations, I’d rather:

• Know exactly what I’m paying for (impressions, clicks, conversions)
• Understand the ranking factors and bidding mechanisms
• Optimize my spend based on clear ROI metrics
• Compete on a level playing field where everyone knows the rules

The current model, where “organic” results are influenced by undisclosed commission structures, creates uncertainty for merchants and users alike. At least with a clearly labeled ad system, we’d know which results are paid placements and could make informed decisions.

How does ChatGPT instant checkout tackle reviews?

Here’s a critical advantage that platforms like Amazon have spent two decades building: Millions of verified customer reviews.

When you search for “wireless headphones” on Amazon, you’re seeing products validated by thousands of (mostly) real customer experiences. Those reviews represent an insurmountable moat for newer platforms.

ChatGPT faces the same challenge. When it recommends products, where do the quality signals come from? Right now, it’s pulling from across the web…manufacturer descriptions, tech blog reviews, Reddit threads, scattered retailer feedback. But is that as valuable as Amazon’s concentrated, verified review database?

This is both a challenge and an opportunity:

The challenge: ChatGPT recommendations lack the social proof that drives purchase confidence. Without rich review data, how do users trust the AI’s suggestions?

The opportunity: For merchants, this levels the playing field somewhat. You’re not competing against products with 50,000 Amazon reviews. You’re competing in an environment where reputation signals are still forming.

The platforms that solve the review problem, whether through partnerships, aggregation, or new verification methods, will have a massive advantage in AI commerce. It’s one of the most important unsolved problems in this space.

What ecommerce companies should do right now

If you’re selling physical products through Shopify, Etsy, or processing payments via Stripe, here’s the pragmatic approach:

Short-term: Treat Agentic Commerce Protocol like a new distribution channel.

Think of it as discovery + checkout, similar to how you might approach TikTok Shop or Instagram Shopping. It’s another way for customers to find and purchase your products.

Implementing ACP is a low-regret pilot if you already run Stripe, Shopify, or Etsy:

• Merchants already processing payments with Stripe can enable agentic payments in as little as one line of code
• The implementation complexity is minimal
• You maintain control of fulfillment, customer service, and operations
• The downside risk is limited (just the transaction fees)
• The upside could be significant if ChatGPT commerce takes off

It’s similar to the early days of Amazon Marketplace. Not every merchant needed to join immediately, but the ones who piloted early learned the platform dynamics and built advantages that compounded over time.

Key questions to evaluate:

• Does your target customer use ChatGPT for product discovery?
• Are your margins healthy enough to absorb 3-5% platform fees?
• Can your existing systems handle orders from a new channel?
• Do you have competitors already experimenting with this?

If the answers are mostly “yes,” running a 90-day pilot makes strategic sense. If they’re mostly “no,” monitoring the space while focusing on core channels is equally valid.

What B2B and service companies need to understand

You might be thinking: “We sell enterprise software, not yoga pants. Why does this matter?”

Here’s why:

First, AI-mediated discovery affects every category. Even if your prospects never complete a purchase in ChatGPT, they’re increasingly using it to research vendors, compare solutions, and build consideration sets. When a CFO asks ChatGPT “best accounting software for mid-market manufacturing companies,” which three solutions get recommended?

Second, this is about visibility strategy, not just transactions. The companies that appear in AI agent recommendations build mindshare and credibility…even when the actual sale happens through traditional channels.

Ultimately, purchasing directly within ChatGPT is a genuine convenience win for consumers. It’s a meaningful discovery improvement over traditional search. And it’s a fundamental shift in how visibility works for marketers.
