a16z · x · 2026-09-30
a16z investors (David George, Sarah Wang, Alex Immerman, Santiago Rodriguez) published a State of Markets breakdown:
- Tech is the everything cycle: high-tech equipment, software, and R&D are 55% of US capital spending; the AI buildout has passed railroads as a share of GDP. The five largest hyperscalers will spend $780B on capex this year, exceeding $1T by 2027, with demand outstripping supply at every point.
- It's an earnings story: stocks up 20% while multiples compressed 20%; S&P trades under 20x earnings; market up 90% since ChatGPT on 15% earnings growth.
- AI adoption is broad and shallow: 69% of the S&P 500 has live AI deployments, 30% report quantified results, but only 2% have AI doing a job they'd notice if it stopped.
