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 past speculative bubbles, the current AI frenzy has near-universal, top-down support. The government wants domestic investment, tech giants are in a competitive spending arms race, and financial markets profit from the growth narrative. This rare alignment of interests from all major actors creates a powerful, self-reinforcing mandate for the bubble to continue expanding.

The AI boom is fueled by 'club deals' where large companies invest in startups with the expectation that the funds will be spent on the investor's own products. This creates a circular, self-reinforcing valuation bubble that is highly vulnerable to collapse, as the failure of one company can trigger a cascading failure across the entire interconnected system.

According to author Bernd Hobart, bubbles aren't just irrational speculation. Sky-high valuations signal to all players—from power plants to chip fabs to software developers—that the "time is now." This encourages massive, parallel investments that might otherwise be too risky, effectively manufacturing the future just in time.

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.

The current AI investment surge is a dangerous "resource grab" phase, not a typical bubble. Companies are desperately securing scarce resources—power, chips, and top scientists—driven by existential fear of being left behind. This isn't a normal CapEx cycle; the spending is almost guaranteed until a dead-end is proven.

The current AI investment frenzy is a powerful feedback loop. Silicon Valley labs promote a grand narrative to justify huge capital needs. Simultaneously, Wall Street firms earn massive fees by financing this buildout, creating a shared, bi-coastal incentive to keep the 'super cycle' narrative going, independent of immediate profitability.

For the first time, investors can trace a direct line from dollars to outcomes. Capital invested in compute predictably enhances model capabilities due to scaling laws. This creates a powerful feedback loop where improved capabilities drive demand, justifying further investment.

A circular economy is forming in AI, where capital flows between major players. NVIDIA invests $100B in OpenAI, which uses the funds to buy compute from Oracle, who in turn buys GPUs from NVIDIA. This self-reinforcing loop concentrates capital and drives up valuations across the ecosystem.
