The AI vision is finally paying off. Q1 2026 reports show the AI power supply chain is in a massive growth cycle. Tech leaders like Deemly and GigaDevice are seeing profits double or more as the industry races toward high-density power, HVDC, and liquid cooling. We are now in the "payday" phase for high-end AI infrastructure.
Upstream, the chips are leading the charge. GigaDevice saw a 500% profit jump from AI power chips, while storage giants Deemly and Longsys are back in the black thanks to enterprise SSD demand. In the PCB world, Shennan and WUS profit margins surged over 60%. Even passive component makers like Fenghua are seeing steady gains as AI centers gobble up more resistors and capacitors.
Midstream, it’s all about power and cooling. Vertiv doubled its profit as Nvidia's cooling go-to, and Megmeet’s power division revenue climbed 66%. China Great Wall has hit mass production for 5500W modules. Meanwhile, Weichai is seeing 90% growth in generators for data centers, and firms like Eaglerise are testing the waters with Solid-State Transformers (SST) for future grids.
Downstream, the scale is massive. Foxconn (FII) shipped 3.8x more AI GPU cabinets, doubling its net profit. Cloud titans—Amazon, Google, Microsoft—are maintaining double-digit growth, ensuring the order books stay full. While some firms struggle with R&D costs or currency shifts, the sector as a whole is booming.
The Bottom Line: AI is no longer a side project; it is the primary engine for profit. Leading companies are seeing profits outpace revenue, proving that high-value AI gear is a margin goldmine. With new capacity expansions on the horizon and tech like HVDC becoming standard, the AI power chain is set for a long, high-growth run.
