404K Technology Weekly: Cloud CapEx Exceeds One Trillion, Storage Enters Strong Cycle, Photonic Bottleneck Takes Over

Orders for AI infrastructure continue to accelerate, and capital expenditure has expanded from GPU procurement to storage, advanced packaging, networking, power supply, and data center construction. Storage is the first segment to translate shortages into price and profit gains, with optical communication, substrates, equipment, and power supply subsequently receiving orders or capacity verification. Platforms and software are starting to differentiate; the market is willing to pay for hard deliverable constraints, while also beginning to question debt, free cash flow, and AI product revenue.

Overall Judgment for This Week

AI trading has entered the “delivery pricing” stage.The five largest cloud providers are still raising their compute budgets; model usage, enterprise deployment, and in-house developed ASICs are all driving demand. The market’s focus has shifted from merely how many GPUs are purchased to when data centers will be powered on, whether racks can be delivered on time, whether memory and optical interconnects are sufficient, and if capital expenditure can be converted into revenue.

Storage is this week’s most evidenced strong cycle sector.DRAM, NAND, HBM, and enterprise-grade SSDs are all seeing price increases. Long-term agreements are raising the industry floor; Samsung Electronics, Nanya Technology, SK Hynix, and SanDisk have already provided verification regarding profit, financing, or contracts. Supply expansion is concentrated after 2027, so short-term pricing power remains with sellers. The risk is that high prices could stunt end-demand and that the rate of price change will peak after the second half of 2027.

Compute bottlenecks continue to spread outward.Manufacturing controversies around Nvidia’s Kyber racks have not altered the Rubin roadmap, but have exposed the engineering challenges of high-layer-count PCBs, CPO, 800V power supply, heat dissipation, and system yield. As a result, capital is simultaneously buying into mature copper interconnects, Ethernet switching, pluggable optical modules, InP lasers, ABF substrates, and testing equipment. Whoever can mass produce earlier captures revenue first.

The source of funding for capital expenditure is starting to impact valuations.Cloud providers continue to face high backlogs, and companies like Amazon, Google, Meta, Microsoft, and Oracle are pushing financing needs to the bond market. Thus, there is still room for hardware orders to be revised upwards, but platform stocks must simultaneously withstand the pressures of depreciation, interest, and free cash flow. The most important earnings question for the second half of the year will shift from “Will they keep spending?” to “How much cloud revenue, advertising revenue, and rentable compute does each dollar of investment generate?”
