Amazon plans to launch Buy with Prime for all US-based merchants on January 31, letting them access Prime benefits, expanding on Fulfillment by Amazon merchants
Amazon announced this morning it's expanding its Buy with Prime service to U.S.-based merchants by the end of the month.
Context & Ripple Effects
Amazon first introduced [[a:978115|Buy with Prime as a way for third-party merchants to use its shipping and logistics network on their own sites]]. The broader U.S. rollout moves that offer beyond merchants already using Fulfillment by Amazon, extending an approach Amazon had previously tested with Prime-eligible goods shipped directly from merchants.
First-order effects
- U.S.-based merchants outside Fulfillment by Amazon can offer Prime benefits on their own storefronts, while Amazon expands the pool of sellers using its logistics network.
- Prime members gain access to Prime benefits across more merchant-owned sites rather than only through Amazon’s marketplace and existing FBA merchants.
Second-order effects
- Amazon’s fulfillment operation gains a stronger route to merchant demand even when the transaction occurs off Amazon.com, making merchants’ storefronts an additional distribution surface for Prime.
- Merchants that adopt Buy with Prime tie customer delivery expectations more closely to Amazon’s logistics service, raising the value of Amazon’s fulfillment relationship relative to operating shipping independently.
Third-order effects
- If adoption broadens, Prime can function less as a marketplace-only membership perk and more as a commerce infrastructure layer across independent storefronts.
- The rollout extends Amazon’s long-running effort to connect Prime eligibility with merchant-direct sales, potentially concentrating fulfillment influence with the provider behind the consumer benefit.
The trend: Amazon is extending Prime from an Amazon.com benefit into logistics-backed infrastructure for merchants’ own storefronts.
