The AI Revolution in Four Phases, and What It Means for Investors — Crossroads Economy, Part 4 Ch. 14
What Phase Is AI Investing in Right Now?
Every technological revolution passes through four phases, and AI is no exception. Figuring out which phase we’re in is the starting point for an investment strategy.
Phase 1: The Infrastructure Boom (2022–2024)
The period of massive investment in data centers, GPUs, and power infrastructure. Infrastructure suppliers — Nvidia, TSMC, power companies — benefit the most in this phase.
Phase 2: Platform Competition (2024–2026, present)
Big Tech’s rivalry over AI platforms — cloud and AI services — intensifies. Winners lock in a dominant position through network effects; losers absorb massive investment losses.
Phase 3: Application Diffusion (2026–2030)
Companies that actually apply AI to their businesses see rising productivity. In this phase, traditional-industry companies that successfully adopt AI benefit too.
Phase 4: Maturity and Integration (2030+)
AI becomes as taken-for-granted as infrastructure itself. In this phase, investment returns come less from AI itself than from the business models built on top of it.
Where we stand now: at the turning point between Phase 2 and Phase 3 — a period where fears of infrastructure overinvestment coexist with optimism about application growth.
The Crossroads Economy series analyzes the structural turning points of the global economy across 18 chapters.
