The GPU shortage is over, but a cascading series of infrastructure bottlenecks now threatens AI deployment. High-bandwidth memory is completely sold out through 2026 with prices up over fifty percent. Enterprise SSD prices have surged two hundred and fifty-seven percent. AI data centers consume four point four percent of US electricity, projected to hit twelve percent by 2028. This rapid-fire intelligence briefing dissects the cascading infrastructure crisis from memory to storage to network to power, examining why each resolved constraint exposes the next critical limitation. We cover HBM supply dynamics, proprietary accelerators from Google, Microsoft, Amazon, and Meta, the storage crunch driven by inference workloads, thirty terabit per second networking requirements, and the power grid mismatch threatening the entire stack. Essential intel for traders tracking semiconductors, cloud infrastructure, data center REITs, and energy plays positioned around the AI buildout.
