Amazon Business, Amazon's B2B procurement marketplace, has reached a $60 billion annualized sales run-rate, with artificial intelligence and computer vision identified as the technologies reshaping business-to-business ecommerce in 2026, according to reporting from MarketScale.

The $60 billion figure converts the platform's most recent sales pace into a yearly equivalent — a measurement that captures momentum at a point in time rather than a closed annual total. The number matters because it puts a single platform at scale inside a B2B distribution market that trade estimates place in the hundreds of billions of dollars across office products, janitorial, industrial MRO, and lab supplies.

How does the run-rate compare to traditional B2B distribution?

Amazon Business has historically grown by capturing tail-spend — the long tail of low-dollar, high-frequency purchases that traditional distributors have found uneconomical to service through inside sales coverage. The cost-to-serve gap drives the shift: a business buyer sourcing gloves, toner, or wipers through the marketplace skips the quote, the purchase order, and the field rep visit that a distributor's economics would require.

That gap does not just shift volume. It resets the margin ceiling a distributor can defend on the SKUs where Amazon Business competes. A marketplace operating at low take rates, set against a distributor running an inside sales team, establishes a price the distributor cannot match on tail spend without losing money on the order.

What do AI and computer vision actually do here?

MarketScale's reporting points to two technology layers. Computer vision handles product matching, catalog quality, and inspection at a scale that human review cannot match. Generative AI shapes the discovery and search experience, allowing buyers to describe a requirement in natural language and receive a matched SKU, a price, and a delivery date.

The operational effect is a compressed procurement cycle. What once required a phone call, a rep, and a paper purchase order now resolves in a desktop or mobile session. Distributors that cannot match that latency on the same SKUs will continue to see share migrate, transaction by transaction, in the categories where Amazon Business is already a default option.

What is at stake for distributor gross margin

Office products distributors have already absorbed margin compression as Amazon Business captured the small-order tail in their core category. Janitorial, break-room, and basic MRO follow the same pattern. The next wave — industrial MRO and lab supplies — sits inside accounts that pay distributors higher gross margin than office and janitorial ever did.

The remaining margin pool for traditional distribution sits in configured products, regulated categories, integrated supply, vending programs, and on-site service — work that a marketplace fulfillment operation does not perform. Distributors leaning into kitting, labeling, regulatory documentation, and on-site replenishment defend the customer relationship even as Amazon Business owns the digital shelf for the long tail.

What to watch through 2026

MarketScale frames 2026 as the year AI-driven procurement moves from pilot deployment to default behavior. If Amazon Business extends the velocity it has shown in office and janitorial into industrial MRO and lab categories, the $60 billion run-rate marks an intermediate data point rather than a destination — and the pressure on traditional distributor gross margin in those adjacent categories continues to compound.
