Summary
Business Insider argues that the massive AI-related capex boom is inflating reported S&P 500 earnings, masking an uncomfortable truth: much of the profit growth comes from the spending itself rather than genuine end demand. The piece questions whether index earnings could fall sharply once capex growth slows.
Bubble analysis
This speaks directly to a core bubble mechanism: enormous AI capex is running far ahead of AI revenue, and accounting effects (long depreciation schedules, profits recycled to suppliers) are artificially propping up index earnings. If profit growth depends on spending rather than earning, then a capex peak would hit both earnings and valuations — exactly the circularity bubble skeptics warn about.
