$750 billion and $1.2 million

Sequoia's David Cahn expects roughly $750 billion of hyperscaler data-center spending in 2026, and calls the lifetime revenue needed to justify it AI's $1.5 trillion question. In March, Next50 — the Denver foundation trying to organize capital markets around aging — announced its 2026 investments: $1.2 million.

Both are bets on the future. One is speculative; Cahn himself says nothing short of AGI justifies the spend. The other is a certainty with a date on it. The Census Bureau projects adults 65 and older will outnumber children by 2034, and the gap has already narrowed from 20 million to under 12 million since 2020. Behind the US number sits the global one: 2.1 billion people over 60 by 2050.

Next50's framework calls its highest tier "Age-Centered": built for the aging ecosystem, not retrofitted to it. The most valuable unpriced asset in that ecosystem is the family caregiver — 63 million Americans doing the work that makes independence possible. Capital has not noticed them yet. It will.
