In a surprising move, Amazon has announced the reopening of its Seller-Fulfilled Prime (SFP) program, allowing sellers to maintain their Prime badge without relying on Amazon's Fulfillment by Amazon (FBA) warehouses. The program, previously halted due to compliance concerns, is set to return with stricter enforcement measures.

One feature in the latest Shopify Editions release was "Shop Promise." It is a way for Shopify to let buyers know when an item will arrive, thus boosting conversion rates.

Here’s the TL;DR — It's not a Prime competitor and won't be soon. But if you compare yourself to Prime ("no subscription fees!") you had better be prepared for the comparison.
