A wholesaler buys goods in bulk from manufacturers and sells them on to other businesses, such as pharmacies, restaurants and retailers, rather than to the end consumer. Six large U.S. examples, by revenue in their latest annual reports: McKesson ($403.4 billion, fiscal year to 31 March 2026), Cencora ($321.3 billion, year to 30 September 2025), Costco ($303.2 billion, year to 30 August 2026), Cardinal Health ($254.2 billion, year to 30 June 2026), Sysco ($84.6 billion, year to 27 June 2026) and US Foods ($39.4 billion, year to 27 December 2025). The drug wholesalers are the biggest by sales but keep under 4 cents of gross profit per dollar.
How wholesalers make money
What changed in 2025-26
McKesson’s revenue rose 12% to $403.4 billion in fiscal 2026 and Cardinal Health’s rose to $254.2 billion. Cardinal Health says higher demand for GLP-1 medications lifted its revenue but did not meaningfully add to segment profit, which shows how thin the margin on a pass-through drug can be.
US Foods supplies about 250,000 customer locations and leans on its MOXē ordering platform and its Pronto delivery programme. Sysco lists club stores, online food wholesalers and competitors using AI and machine learning as sources of pressure on industry margins.
McKesson says it is in the early stages of exploring AI to improve productivity, Cencora says it is seeking to use AI to improve its operations, and Sysco calls its growing use of AI systems in operations a risk it must manage. For drug wholesalers keeping under 4 cents per dollar, small efficiency gains matter.
Rankings change with each filing. Performance Food Group, for example, reported $67.8 billion of revenue for the year to 27 June 2026, more than US Foods; tech distributors and private grocery wholesalers are also large.

What it means for you
- Brands: a wholesaler buys you reach into thousands of small buyers you could not serve alone; price in its margin and payment terms.
- Founders: in a thin-margin business, scale and logistics decide who wins; check the gross margin per dollar before you copy the model.
- Restaurant and pharmacy owners: compare distributors on delivery reliability and ordering tools, not only on list price.
- Investors: watch gross margin and mix; revenue from pass-through products like GLP-1 drugs can grow far faster than profit.
- Operators: start AI where a fraction of a cent per dollar matters most, such as routing, inventory and order entry.
Wholesale is a scale and logistics game with margins measured in cents, so the first gains from AI are likely to come in routing, inventory and ordering rather than in new products. The Business Engineer reads the 2026 filings as a reminder that revenue size and profit pool are very different things in distribution.

Visual overview and quick answers (tap to expand)
Introduction
A wholesale business purchases goods in bulk from a supplier and then sells them to other merchants in smaller quantities. The wholesaler relies on economies of scale to receive a discount price from the manufacturer and then adds mark-up before selling to the merchant. Most merchants are not the end-user of the product, but as we will discover later, there are exceptions to this rule.
Wholesalers play an important role in the market. They maintain supply-demand equilibrium by storing goods until there is merchant demand. What’s more, a wholesaler is responsible for the distribution and transportation of goods from their warehouse and bears the risks associated with product shrinkage or fluctuations in demand.
The rest of this article will be devoted to discussing some specific wholesale business examples.
Costco

Costco, also known as Costco Wholesale Corporation, is an American multinational big-box retail chain founded by James Sinegal, Jeffrey Brotman, Sol Price, and Robert Price in 1976.
Costco is a membership-only warehouse that requires consumers to purchase a membership before they can shop. The company is somewhat unusual in that it is a retailer and a wholesaler at the same time. In other words, Costco purchases wholesale products from the manufacturer and sells them to the end-user. However, the company also sells the same goods to other businesses under a more traditional wholesale business model.
