NVIDIA data center compute revenue declines 0.9%, showing early signs of growth plateau.

Nvidia's second quarter fiscal 2026 results reveal a significant inflection point for the chip giant: data center compute revenue declined for the first time in a decade. The drop, while modest at 0.9 percent compared with the previous quarter, marks a notable turning point after years of sustained growth in the company's core GPU and CPU business. Despite this setback, Nvidia reported record overall revenues, suggesting the company's broader diversification is offsetting weakness in its primary AI infrastructure segment.

The decline in compute sales comes amid a fundamental shift in customer spending patterns. Networking revenues tell a markedly different story, with InfiniBand networking nearly doubling and Ethernet and other interconnects showing significant gains. The combined networking segment delivered $7.25 billion in revenue during the July quarter, indicating that customers are channeling more spending into interconnects that link AI clusters at scale.

This rebalancing occurs under considerable pressure from export restrictions to China, which have already cut into expected compute sales. Chief executive Jensen Huang insisted during the earnings call that "fiscal 2026 and 2027 will still be record years," though the curve on the data center chart presents a concern. Huang has argued that 50 percent growth in data center compute can continue for years, but market realities may force slower trajectories.

A critical vulnerability underlying Nvidia's position is its dependence on a small number of customers. More than half of data center revenue now comes from just three unnamed clients, with one alone accounting for over 20 percent of sales. The most recent quarter saw $9.5 billion from Customer A, $6.6 billion from Customer B, and $5.7 billion from Customer C. While demand for Nvidia's Blackwell GPUs remains solid with supply reportedly sold out into next year, the revenue plateau hints that Nvidia's dominance may be entering a more uncertain phase.
