a16z’s David George, Sarah Wang, Alex Immerman, and Santiago Rodriguez examine $780B hyperscaler CapEx and AI adoption’s 2% measurable impact.
a16z’s David George, Sarah Wang, Alex Immerman, and Santiago Rodriguez review 25 charts on markets, AI, and investment. They argue the market’s rise has been earnings-led, while hyperscaler CapEx is projected to reach $780 billion in 2026 and exceed $1 trillion annually from 2027 as compute demand outstrips supply. The buildout feeds chips, power, construction, and a broader $90 trillion infrastructure need through 2040. Enterprise AI is spreading, but only 2% of S&P 500 companies track its impact over time; power users can spend more than 20 times the median. The discussion covers AI’s effects on marketplaces and software, Stripe customer growth, and private-company valuations. They close with opportunities in agents, robotics, autonomous vehicles, biotech, and modernizing US infrastructure.
