Speculative manias, like the AI boom, function like collective hallucinations. The overwhelming belief in future demand becomes self-fulfilling, attracting capital that builds tangible infrastructure (e.g., data centers, fiber optic cables) long before cash flows appear, often leaving lasting value even after the bubble bursts.

Unlike the previous era of highly profitable, self-funding tech giants, the AI boom requires enormous capital for infrastructure. This has forced tech companies to seek complex financing from Wall Street through debt and SPVs, re-integrating the two industries after years of operating independently. Tech now needs finance to sustain its next wave of growth.

A financial flywheel, reminiscent of the pre-2008 crisis, is fueling the AI data center boom. Demand for yield-generating securities from investors incentivizes the creation of more data center projects, decoupling the financing from the actual viability or profitability of the underlying AI technology.

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.

For the first time in years, leading-edge tech is incredibly expensive. This requires structured finance and massive capital, bringing Wall Street back to the table after being sidelined by cash-rich tech giants. The chaos and expense of AI create a new, lucrative playground for financiers.

The startup landscape now operates under two different sets of rules. Non-AI companies face intense scrutiny on traditional business fundamentals like profitability. In contrast, AI companies exist in a parallel reality of 'irrational exuberance,' where compelling narratives justify sky-high valuations.

The massive investment in AI infrastructure could be a narrative designed to boost short-term valuations for tech giants, rather than a true long-term necessity. Cheaper, more efficient AI models (like inference) could render this debt-fueled build-out obsolete and financially crippling.

The AI infrastructure boom has moved beyond being funded by the free cash flow of tech giants. Now, cash-flow negative companies are taking on leverage to invest. This signals a more existential, high-stakes phase where perceived future returns justify massive upfront bets, increasing competitive intensity.

The massive capex spending on AI data centers is less about clear ROI and more about propping up the economy. Similar to how China built empty cities to fuel its GDP, tech giants are building vast digital infrastructure. This creates a bubble that keeps economic indicators positive and aligns incentives, even if the underlying business case is unproven.
