Amazon has spent years trying to make its logistics network the default backbone of e-commerce — not just on Amazon.com, but everywhere. The latest move might be the one that actually gets it there.

What's Being Tested

Amazon is piloting a program, first reported by Business Insider and confirmed by TheStreet, that would let shoppers on third-party websites receive Prime shipping benefits without logging into an Amazon account. The initiative, internally codenamed "Confidential Product," is being tested with a small group of merchants who already use Amazon's Multi-Channel Fulfillment (MCF) service.

The key difference from the existing Buy with Prime program: no Amazon login required. Amazon validates Prime membership in the background, and the entire checkout experience stays on the merchant's own site. The brand keeps the customer relationship. Amazon handles the boxes.

Why the Login Was the Problem

Buy with Prime launched in April 2022 and expanded to all U.S. merchants by January 2023. The pitch was compelling — offer your DTC customers the Prime shipping speed they expect, using Amazon's fulfillment network. Orders through merchant websites grew more than 45% year-over-year as of late 2024.

But adoption hit a ceiling, and the login requirement was the main culprit. Asking a customer who's already on your website to authenticate through Amazon mid-checkout created friction that undercut the program's value. As ShopiFreaks reported, many DTC brands felt that redirecting customers to Amazon's authentication flow disrupted the native experience they'd worked hard to build — and handed data to their biggest competitor.

Removing the login solves the friction problem. It also makes the program dramatically more attractive to the premium DTC brands that have historically kept Amazon at arm's length.

The Business Case Is Enormous

Amazon reportedly expects the loginless model to generate roughly $260 million in operating profit by 2027 if fully rolled out by September 2026, according to ShopiFreaks. That figure likely understates the strategic value: every merchant using Amazon MCF deepens the logistics moat that already handles more packages than UPS or FedEx in the United States.

For context, Amazon and Shopify now control approximately 50% of U.S. e-commerce. This move pushes Amazon's infrastructure even further into the Shopify half of that equation — and into any other platform where merchants want fast shipping without building their own fulfillment network.

What It Means for Shopify (and Everyone Else)

The timing is notable. Just last week, Shopify activated its Agentic Storefronts initiative, making merchant products discoverable inside ChatGPT, Gemini, and Copilot. Shopify's bet is on the discovery layer — being the platform where AI shopping agents find products. Amazon's bet is on the delivery layer — being the network that ships them, regardless of where they're sold.

These aren't directly competitive moves, and many merchants will use both. But they represent two very different visions of who owns the e-commerce value chain in an AI-mediated shopping future. Shopify wants to own the storefront. Amazon wants to own the last mile.

The Catch

There are open questions. How does Amazon verify Prime membership without a login? The technical details haven't been made public, and privacy implications of background authentication are non-trivial. Merchants also need to trust that Amazon won't use fulfillment data to compete with them directly — a concern that has dogged Buy with Prime since launch.

For now, this is a small pilot. But if the loginless model works, expect Amazon to push it aggressively. The company recently added fuel and logistics surcharges to MCF orders — a reminder that building on Amazon's infrastructure means being subject to Amazon's pricing power, especially when Hormuz-driven oil spikes hit the delivery fleet.

The pitch is seductive: give your customers Prime speed without giving up your brand. The question is whether the trade-off is worth it when the logistics partner is also the market's largest retailer.
