AI Spending Boom Faces Profitability Reckoning as Half of S&P Earnings Growth Hinges on Capex

What’s happening
Half of S&P 500 earnings growth is now attributable to AI-driven capital expenditure, but investors are questioning whether the billions poured into data centers will generate sufficient returns. The AI boom is entering a "gut check" phase as the market demands proof that infrastructure spending translates to revenue and margin expansion, not just balance sheet growth.
Market impact
A slowdown in AI capex or disappointing ROI metrics could trigger a sharp earnings revision across semiconductors, cloud infrastructure, and enterprise software. Valuations of AI-exposed names are now hostage to capex discipline and monetization success. Any signal that data center utilization or pricing is weakening will pressure the entire AI supply chain.
Broader implications
The AI capex cycle is becoming a macro bellwether. If returns disappoint, it could signal a broader corporate investment pullback and earnings recession. Conversely, if AI monetization accelerates, it justifies current valuations and sustains the bull case through 2025.
