Now — 2028
The AI infrastructure supercycle, advanced chips, and the energy buildout that powers it.
This horizon is the most investable. Milestones are well-defined, companies are identifiable, and capital is already flowing at scale.
The Big Picture
We are in the early innings of the largest infrastructure buildout in human history. AI is the demand driver. Chips, data centres, power, and networking are the supply response. Every milestone below has named companies and stock implications.
Milestones

Investment Implications
- TSMC and ASML remain the two most irreplaceable companies in the global chip supply chain
- Power infrastructure (ETN, GEV, PWR) is the most underloved AI derivative play
- Memory (MU) enters a multi-year upcycle on HBM demand
- ARM royalty model scales with every AI server chip shipped
