The strongest evidence that corporate AI spending is generating real ROI is that major tech companies are not just re-ordering NVIDIA's chips, but accelerating those orders quarter over quarter. This sustained, growing demand from repeat customers validates the AI trend as a durable boom.

Unlike the dot-com bubble's speculative fiber build-out which resulted in unused "dark fiber," today's AI infrastructure boom sees immediate utilization of every GPU. This signals that the massive investment is driven by tangible, present demand for AI computation, not future speculation.

The bank asserts that the massive wave of AI and data center capital expenditure will proceed regardless of interest rate levels or overall economic growth. This suggests the demand for computing power is a powerful secular trend that transcends typical cyclical business investment patterns.

Despite huge demand for AI chips, TSMC's conservative CapEx strategy, driven by fear of a demand downturn, is creating a critical silicon supply shortage. This is causing AI companies to forego immediate revenue.

The world's most profitable companies view AI as the most critical technology of the next decade. This strategic belief fuels their willingness to sustain massive investments and stick with them, even when the ultimate return on that spending is highly uncertain. This conviction provides a durable floor for the AI capital expenditure cycle.

While energy supply is a concern, the primary constraint for the AI buildout may be semiconductor fabrication. TSMC, the leading manufacturer, is hesitant to build new fabs to meet the massive demand from hyperscalers, creating a significant bottleneck that could slow down the entire industry.

Unlike the dot-com era's speculative infrastructure buildout for non-existent users, today's AI CapEx is driven by proven demand. Profitable giants like Microsoft and Google are scrambling to meet active workloads from billions of users, indicating a compute bottleneck, not a hype cycle.

Critics like Michael Burry argue current AI investment far outpaces 'true end demand.' However, the bull case, supported by NVIDIA's earnings, is that this isn't a speculative bubble but the foundational stage of the largest infrastructure buildout in decades, with capital expenditures already contractually locked in.

Unlike railroads or telecom, where infrastructure lasts for decades, the core of AI infrastructure—semiconductor chips—becomes obsolete every 3-4 years. This creates a cycle of massive, recurring capital expenditure to maintain data centers, fundamentally changing the long-term ROI calculation for the AI arms race.
