Amazon's $220B Capex Plan Signals Tech's FCF Tension

Five earnings reports. One question sits underneath all of them: is AI capex a moat, or a liability, depending on what's backing it?

Every hyperscaler raised spending guidance. Every stock moved higher on the news. But look past the headline number, and the cash flow statements tell four different stories.

AMZN — Trainium chips sold out despite a $220B capex increase MSFT — $100B Azure run-rate keeps funding its own expansion GOOGL — 82% cloud growth, yet free cash flow turned negative NVDA — A nuclear reactor is now directly powering its Blackwell chips PLTR — Commercial revenue growth now outpaces government, without a capex race

Same AI cycle. Four different paths through it.

The market priced every one of these moves as good news. The balance sheets didn't all agree. If contracted revenue is what separates funded capex from unfunded capex, how much of this quarter's rally is pricing that difference — and how much is pricing the story around it?
