Two things happened in the last few months that will determine who controls your checkout. One creates an opportunity. The other sets the rules for how far AI agents can go.
In May 2025, Perplexity selected PayPal to power agentic commerce on its platform. By summer 2025, users could check out with PayPal or Venmo directly inside Perplexity's chat interface. No browser. No separate tab. No typing in a card number. The AI found the product, the AI completed the purchase.
Then in March 2026, a U.S. federal judge issued a preliminary injunction blocking Perplexity's Comet browser from accessing Amazon's password-protected sections to make purchases for users. The court's logic was specific: user consent doesn't equal platform authorization. A customer can tell an AI agent to shop for them. That doesn't mean Amazon has to let the agent in.
That distinction matters more than the ruling itself.
If you run a Shopify store, here's what both developments mean for you and what to do about them.
1. Register Your Product Data with PayPal Store Sync
PayPal quietly launched a feature called Store Sync before the end of 2025. It makes your product catalog discoverable inside AI channels, including Perplexity. If your data isn't in there, Perplexity's agent can't surface your products when a user asks it to find something to buy. You're invisible by default. Getting into Store Sync is the fastest path to being part of agentic purchases on Perplexity before the wider rollout.
2. Audit Your Terms of Service for AI Agent Access
The Amazon Comet case drew a hard line: platforms can block AI agents even when the user has given that agent permission to act. Read your own terms of service. Are you explicitly allowing or blocking automated agent access? If you don't have a clear position, you're in the gray zone. That's where liability lives. Most Shopify stores have default terms that were written before agentic commerce existed. Update yours now.
3. Clean Up Your Product Feed Before Agent Ready Launches
PayPal's "Agent Ready" payment solution was slated for early 2026. It lets existing PayPal merchants accept payments initiated by AI agents, whether through conversational AI or browser-automated flows. It also includes fraud detection and buyer protection. The merchants who will get the most out of Agent Ready are the ones with clean, complete, structured product data. If your titles are vague, your descriptions are thin, or your product attributes are incomplete, an AI agent has no reliable way to match your item to a buyer's request. Fix the feed first.
4. Enable PayPal and Venmo Checkout on Your Store
This sounds obvious. It's not obvious to most store owners. As of June 2026, Perplexity's agentic checkout routes purchases through PayPal and Venmo. If you don't have those payment methods active on your store, you can't participate in that checkout flow. Full stop. Go into your Shopify payments settings and confirm both are enabled. It takes ten minutes. Not having them enabled is the same as locking the door before anyone can knock.
5. Track the Amazon Comet Appeals Case
The preliminary injunction is not the final word. A U.S. appeals court paused the injunction shortly after it was issued. This case is still moving. Search Engine Journal covered the initial ruling, and legal analysts at Mogin Law have tracked the broader implications. The final decision will define the legal boundaries for every AI agent that touches a product page. Watch it. When it settles, update your terms of service and your access policies accordingly.
Why Both Developments Point to the Same Problem
The Perplexity-PayPal deal is about access. If your store is set up correctly, AI agents can find you and buy from you without a human ever visiting your site. That's new revenue you didn't have to earn with ads.
The Amazon Comet ruling is about control. Platforms get to decide who can access their systems, regardless of what the user has authorized. Amazon used that principle to block Comet. You can use it too. Or you can use it to explicitly welcome agents, which is a competitive advantage most stores haven't even considered yet.
The stores that win in agentic commerce won't be the ones with the best ads. They'll be the ones whose data is clean, whose checkout is ready, and whose terms of service say "you're welcome here."
I've watched this movie before. When Facebook changed its algorithm in 2013, the stores that had already built their ad infrastructure kept growing. The ones who waited lost ground they never got back. The window to get ahead of agentic commerce is open right now. It won't stay open forever.
Frequently Asked Questions
What is the Perplexity PayPal integration and how does it affect my store?
Perplexity selected PayPal to power purchases made directly inside its AI chat interface. Users can search for a product, and Perplexity's agent can complete the checkout using PayPal or Venmo without leaving the conversation. If your store accepts PayPal and your products are discoverable in PayPal's Store Sync, you can receive orders through this channel. If not, you're excluded from it entirely.
What was the Amazon Comet ruling and why does it matter to Shopify merchants?
In March 2026, a federal judge issued a preliminary injunction blocking Perplexity's Comet AI browser from accessing Amazon's platform to make purchases on users' behalf. The ruling established that user permission doesn't automatically mean platform authorization. For independent merchants, this precedent means you get to decide whether AI agents are welcome on your store. It's a policy decision, not just a technical one.
What is PayPal's "Agent Ready" solution?
Agent Ready is PayPal's agentic payment product designed to let existing PayPal merchants accept payments initiated by AI agents. It includes fraud detection, buyer protection, and dispute resolution built specifically for AI-initiated transactions. It was targeted for early 2026 availability for PayPal merchants.
Do I need to do anything special to be eligible for agentic purchases through Perplexity?
Three things: PayPal or Venmo must be active as a checkout method on your Shopify store, your product data needs to be clean and structured enough for an AI agent to match it to buyer requests, and you should register your product catalog with PayPal's Store Sync to ensure your products are visible inside AI channels including Perplexity.
What happens if an AI agent makes a purchase on my store that goes wrong?
PayPal's Agent Ready solution includes buyer protection and dispute resolution for AI-initiated transactions. But your own terms of service matter too. If your policies are written for human buyers only, agent-initiated disputes fall into undefined territory. Update your terms to address AI agent transactions explicitly. This is both a risk management step and a signal to buyers that your store is ready for agentic commerce.
What to Do Next
Agentic commerce is not a 2027 problem. PayPal already has merchants transacting through Perplexity. The Comet ruling is being appealed. Shopify is building its own agentic infrastructure. The brands that get structured, get visible, and get their checkout ready now will have a compounding advantage over the ones who wait.
We audit Shopify stores specifically for AI commerce readiness. Structured data, product feed quality, payment compatibility, terms of service gaps. If you want to know where your store stands before the next wave hits, start there.
