Speaking at the Economic Club of Chicago two weeks ago, CEO Ron Vachris said Costco applies AI across pharmacy, fuel operations, accounting and IT as an assistive tool that has driven sales uplifts in some areas and has not been used to cut staff.
Ron Vachris, CEO of Costco, told the Economic Club of Chicago two weeks ago that the company deploys artificial intelligence to augment its roughly 341,000 employees rather than to replace them. He framed the shift as materially important to operations and results, saying AI has produced measurable benefits in specific departments while the business continues to grow.
Vachris outlined concrete uses of AI across pharmacy, gas stations, accounting and parts of the company’s IT function. He said the technology "has been extremely good for our company in an assistive nature," and noted in IT that the system "was writing some code." He also linked AI deployments to increased sales in some areas, citing pharmacy as an example of a department that has seen uplift.
On workforce effects, Vachris stressed Costco has not used AI to displace people. "We've not displaced people because now the business is growing at a faster rate," he told the audience, and he described employees who previously handled routine tasks being moved into more forward‑thinking roles. That repositioning, he argued, lets the company automate repetitive work while elevating staff into higher‑value activities.
Vachris also pushed back on handing major decisions over to machine systems. He said some decision‑making at Costco "will never be outsourced to artificial intelligence," positioning AI as a tool to improve workflows rather than to assume leadership or make core strategic calls. He added that "Everyone that we put in place has enhanced the business," attributing gains to targeted, supervised deployments rather than autonomous systems.
His remarks came amid broader labor tensions in which employees worry about job loss even as executives elsewhere sometimes cite AI as a factor in layoffs. Vachris used Costco’s experience — sales gains in parts of the business and automation in IT-as evidence that an augmentation‑first approach can coexist with workforce growth rather than immediate headcount reductions. For builders and operators, Vachris’s takeaway is operational: apply AI in assistive roles that integrate with existing systems across retail functions and monitor concrete business effects. By focusing on complementary deployments and maintaining human decision authority, the company aims to both raise employee roles and secure incremental commercial gains.
