Amazon says sales from Amazon Business, its business-to-business platform that launched in 2015, hit an annualized rate of $10B globally
- Business-to-business platform launched three years ago — Customers include schools, hospitals and corporations
Context & Ripple Effects
Three years in, Amazon Business has compounded fast: it cleared $1B+ in US sales in year one and then pushed into the UK's £96.5B online B2B market, followed by a deliberate move into medical supplies aimed at US hospitals. The $10B global annualized run rate reported here is the first confirmation that those vertical bets added up to scale beyond the core office-supply base.
What makes the number matter is who the customers are — schools, hospitals and corporations — meaning Amazon is now selling recurring, contract-like procurement, not just one-off purchases. The later trajectory bears this out: by mid-2026 the unit had reached $60B in annualized gross sales across 11M+ organizations.
First-order effects
- Amazon converts its retail logistics and marketplace infrastructure into a second revenue engine, with business purchasing now material enough to report as a distinct line alongside consumer retail.
- Hospitals and other institutional buyers gain a direct alternative to their existing supply contracts, validating the medical-supply expansion Amazon laid out earlier in 2018.
Second-order effects
- Incumbent medical-supply and office-products distributors face price and delivery-speed competition on their home turf, since Amazon is bundling its fulfillment network into institutional procurement.
- Success in the UK entry signals a repeatable playbook — replicate the US marketplace country by country — forcing regional B2B wholesalers to defend accounts Amazon has not yet entered.
Third-order effects
- If the pattern holds, B2B procurement consolidates around consumer-style marketplaces where selection, transparent pricing and fast shipping replace negotiated distributor relationships — a shift the 2026 $60B run rate confirms rather than merely predicts.
- Vertical depth (hospitals, schools) becomes the battleground: whoever owns the catalog and compliance requirements for regulated institutional buyers locks in switching costs that generalist retailers cannot easily match.
The trend: Institutional purchasing is migrating from contracted distributors to Amazon-style B2B marketplaces, with Amazon Business scaling from a $10B experiment into a multi-hundred-billion-dollar procurement layer.
