A $15T US distribution market where spec-driven B2B procurement is among the earliest agentic-commerce use cases.
US manufacturing and wholesale distribution sales reached $15.12T in 2025 (Digital Commerce 360, Census-based), but overall sales grew just 0.4% while the digital-commerce share of that volume expanded at a double-digit pace. Read those two numbers together: the physical business is essentially flat, and the entire growth story is channel mix, as buyers move ordering from phone, fax and EDI onto e-commerce and marketplace interfaces. That same spec-driven, repetitive buying pattern is what makes B2B procurement one of the earliest and most exposed use cases for agentic AI in the sector.
Every industrial and consumer supply chain runs through distribution, with the US, Germany and China the largest hubs. The segment fragments by category — industrial, medical, food, electronics distribution — with category-specific rollups underway in areas such as HVAC and medical supply. Distributors sit directly between manufacturers and retail or business buyers: classic middleman economics, low single-digit net margins on the physical side, heavy working-capital and logistics intensity. The digital ordering and marketplace layer built on top of that physical base carries software-like margins, and that is where the segment's real value creation concentrates.
Near-flat physical volume against double-digit digital-channel growth is the central fact of the segment right now. Distributors are not selling meaningfully more product; they are capturing more of the existing volume through a channel that costs less to serve — no field-sales visit, no phone-based order entry — so margin expansion is coming from mix, not from unit growth or pricing power. It also makes the sales-rep relationship, still the dominant channel in technical and complex categories, the asset every distributor is racing to protect or digitize on its own terms before a buyer does it for them.
Moving customers from EDI to e-commerce interfaces protects the base against Amazon Business and vertical B2B marketplaces; platform revenue layered on top of the core distribution business is where the new dollars come from.
Procurement is a natural early case for agentic commerce because B2B buying is already spec-driven and repetitive — a buyer reordering the same SKU at the same volume on a set cadence is close to an automatable transaction by design. AI purchasing agents that take over reorder and replenishment go straight at the distributor sales-rep relationship — the actual moat in this business, more than scale or catalog breadth — and compress field-sales cost structures faster than in any other segment in the sector. The dislocation is already underway in commoditized categories such as MRO and office supply; technical distribution, where product complexity still requires human judgment, is expected to follow on a 2-5 year horizon.
