Hyperscaler capital expenditure specifically on memory architecture leaps from approximately 8% of total AI capex (2023) to 30% by end-2026 — High Bandwidth Memory (HBM) and DRAM face severe structural supply constraints with DRAM prices more than doubling. | Q2 2026 memory-maker earnings

Key catalyst: Q2 2026 memory-maker earnings

Watch events: DRAMeXchange spot prices; HBM allocation; Micron/Samsung/SK Hynix quarterly guidance

HBM4 pricing, DRAM spot prices up 80%+ YoY Q4-2025 → Q1-2026; Micron/Samsung/SK Hynix record capex guidance for agent-era memory.
