Micron Hikes Capex to $25B for AI Demand

🔑 Enhanced Key Takeaways

• •Micron expects AI memory demand to outstrip supply through 2026, with HBM4 shipments starting early in the year and 1-gamma DRAM node ramping to dominate output by H2 2026[1].
• •Industry-wide DRAM and NAND shortages, described as unprecedented, are constraining production for companies like Tesla and Apple, with HBM demand rising 70% YoY in 2026 and comprising 23% of DRAM wafers[2].
• •Micron is advancing greenfield expansions like Idaho One online in mid-2027 and NAND capacity in Singapore by 2028, alongside multi-year supply agreements for customer assurance[1].
• •Memory prices are at multi-year highs due to AI pivot, causing 15-20% consumer price hikes and 7% PC market contraction, with LPDDR5X siphoned to servers[3].

🛠️ Technical Deep Dive

• •HBM4 employs hybrid bonding for denser stacks and faster data transfer speeds compared to prior generations[3].
• •Micron's 1-gamma (1γ) DRAM node provides supply into 2026, expected to represent majority of bits in H2 2026 via node transitions[1][3].
• •LPDDR systems shipping in 2026 feature triple the content vs. prior year, reducing time to first token by 98% and boosting inference[1].
• •NVL72 AI server uses 13.4TB RAM per rack, equivalent to memory for 1000 high-end smartphones[2].
