The AI Trade
The largest capex super-cycle in tech history is being built right now. The four biggest US hyperscalers are spending on the order of ~$700B in 2026 - roughly triple their 2024 spend - and OpenAI's Stargate alone has committed ~$450B and ~8 gigawatts. That money flows down a physical stack: accelerators and custom ASICs, the memory (HBM) and advanced packaging that feed them, the optics and switches that network them, and - increasingly the binding constraint - the power, grid and cooling to run them. The investable edge is in the picks-and-shovels: the suppliers whose order books are contracted out to 2027-2028 while the end-demand is still accelerating.

Memory / HBM
- HBM market ~$50-60B+ in 2026 (~+60% YoY); projected to exceed the entire 2024 DRAM market by 2028. BofA / SK Hynix outlook
- Demand bit-growth +130% (2025), +70% (2026); ~20% HBM3E price hike for 2026; HBM4 mass production from ~Feb 2026. TrendForce
- Share (2025-26): SK Hynix ~50-60%, Samsung ~20-35%, Micron ~11-21% (and roughly 20% of next-gen HBM4, where SK Hynix/Samsung/Micron split ~50/30/20). Counterpoint / TrendForce / Astute, 2026
Advanced packaging & semicap
- TSMC CoWoS capacity doubling yearly: ~35K (2024) to ~75K (2025) to ~120-130K wafers/month (end-2026); fully booked. TrendForce, 2025-26
- Advanced-packaging market ~$46B (2024) to ~$55-79B (2030), AI segment the fastest (~15% CAGR). Yole / Grand View
Networking & optics
- AI back-end switch spend >$100B cumulatively 2025-2029; Ethernet already 2/3+ of AI-cluster switch sales. Dell'Oro
- Optical transceivers >$23B (2025) to ~$26B (2026); 1.6T units ~1M (2025) to ~5M (2026); co-packaged optics scaling from ~2027. LightCounting, 2025-26
Power & grid
- US data-center demand ~21 GW (2024) to ~45-94 GW (2030); ~176 TWh (2023) to ~325-580 TWh (2028); global ~950 TWh by 2030. EPRI; DOE/LBNL; IEA
- GE Vernova ~100 GW combined gas backlog (44 GW firm + 56 GW non-binding reservations); lead times 5-7 years. GE Vernova Q1 2026
Cooling & electrical build
