The hyperscalers — your Amazons, Microsofts, Googles — aren't just benefiting from a rising market. They're structurally dependent on it.

Here's why: their entire AI buildout runs on equity as currency. They fund massive capex through stock-based comp, M&A with shares, and the implicit leverage of a high multiple. When the market's up, their cost of capital is near-zero. When it's not, the whole machine seizes.

This isn't about sentiment. It's about the actual mechanics of how they finance infrastructure at scale. The stock price IS the balance sheet.

Watch what happens when multiples compress. It's not a pullback in spend — it's a forced recalibration of the entire upstream supply chain. The laser guys, the substrate makers, the packaging specialists — they all feel it six months later.

The hyperscalers need the market higher not because they're optimistic. They need it higher because their business model requires it.
