Wesco's data center sales jumped 45% in Q2 as AI infrastructure demand reshapes B2B distribution

Wesco International's data center segment posted 45% sales growth in the second quarter of 2026, according to Digital Commerce 360, making it one of the fastest-growing product lines in B2B electrical and industrial distribution. The number is not incremental. It reflects what happens when enterprise AI infrastructure buildout collides with a distributor that has the supply-chain depth to fulfill large, complex orders for power, cabling, and connectivity equipment at scale.

The result lands as Wesco is simultaneously investing in its own AI capabilities, a dual posture, selling into AI-driven infrastructure demand while deploying AI internally, that is becoming a defining competitive move for distributors operating at enterprise scale.

Data centers are now a top-line driver, not a niche

For procurement and supply-chain teams sourcing electrical, networking, and power infrastructure, Wesco's Q2 figure carries a direct implication: the company is prioritizing this segment, which typically means dedicated inventory positions, specialist sales teams, and preferred supplier agreements that can benefit large buyers. Digital Commerce 360 reported the 45% growth as Wesco continues to align its go-to-market around AI and data center customers.

The broader industry context matters here. Global ecommerce is on a sustained upward trajectory, and B2B distribution is not immune to the forces reshaping how buyers source products. Distributors that can combine physical supply-chain scale with strong digital ordering capability are increasingly capturing spend that once flowed through fragmented, phone-based procurement processes.

Digital revenue share is rising across distribution

Wesco's data center surge does not stand alone. HVAC and refrigeration distributor Watsco reported 13% ecommerce sales growth in the same period, with digital revenue reaching 37% of total company sales, according to Digital Commerce 360 reporting by Beth Duckett published July 31. That figure is notable: more than a third of Watsco's revenue now flows through digital channels, a shift that took years of platform investment to achieve and that competitors are only beginning to close.

For operations and procurement leaders, the Watsco number reframes how to evaluate a distributor partner. Digital revenue share is becoming a proxy for ordering reliability, data integration capability, and the ability to connect a distributor's inventory systems to a buyer's ERP or procurement platform. At 37%, Watsco is past the point where digital is an experiment; it is the primary channel for a large portion of its customer base.

The pattern across Wesco and Watsco points to a durable shift in B2B distribution: digital investment is compounding into revenue share, and the distributors furthest along that curve are pulling ahead on both growth rate and customer stickiness.

Amazon's Q2 growth reinforces the AI and cloud spending cycle

Amazon reported 20% sales growth in Q2 2026, with AWS and Prime Day volume identified as the primary drivers, according to Digital Commerce 360's Abbas Haleem. For enterprise procurement teams, the AWS piece is the signal. It confirms that cloud infrastructure spending, the same demand wave lifting Wesco's data center business, is still accelerating rather than plateauing. Organizations expanding their AI workloads are growing their AWS footprint, and that compute demand ultimately traces back to physical infrastructure: servers, power systems, cooling, and the cabling and connectivity products Wesco distributes.

Amazon's Prime Day contribution to the Q2 number also matters for procurement and sourcing teams that use Amazon Business as a direct purchasing channel. Sustained platform growth at Amazon's scale typically correlates with expanded selection, competitive pricing pressure on suppliers, and continued investment in business-buyer features. According to Forbes, global ecommerce continues to grow as a share of total retail, a trend that applies equally to B2B procurement channels.

What operators should watch in the second half of 2026

Three dynamics are worth tracking closely. First, data center infrastructure lead times: Wesco's 45% growth rate signals that demand is outpacing what many distributors budgeted for, which can create allocation pressure on high-demand SKUs. Procurement teams building or refreshing data center capacity should reassess their sourcing timelines now rather than in Q4.

Second, digital integration depth with distributor partners. The gap between a distributor at 10% digital revenue and one at 37% is not just a sales metric; it reflects how deeply that distributor has integrated its systems with customer workflows. Evaluating a distributor's digital maturity is increasingly relevant to procurement efficiency, order accuracy, and spend visibility.

Third, the AWS growth trajectory is a leading indicator for physical infrastructure demand. If AWS revenue continues to accelerate through the back half of 2026, the downstream pull on power, connectivity, and cooling equipment will follow. Wesco's Q2 result suggests that pull is already well underway.
