When discussing artificial intelligence at the G20, Nvidia's (NVDA) CEO did not focus on GPUs or the latest chips, but instead presented a more foundational framework: the AI economy is like a "five-layer cake," with energy at the bottom layer, followed in order by chips, the land and data center infrastructure hosting the systems, models, and finally the data and applications that create commercial value.

TradingKey - Investors were once concerned that artificial intelligence would disrupt traditional software business models, weakening software companies' competitive moats and pricing power. Under this logic, cybersecurity stocks were also sold off alongside the broader software sector, with both CrowdStrike (CRWD) and Palo Alto Networks (PANW) pulling back significantly from their 2025 highs.

Within the AI data center supply chain, memory and storage are irreplaceable. AI accelerators require high-bandwidth memory to transfer data, while training and inference systems rely on high-capacity DRAM and enterprise SSDs to store models, data, and intermediate results. Among key players, Micron (MU) maintains a presence across DRAM, HBM, and NAND, whereas SanDisk (SNDK) places its main bet on NAND flash memory and enterprise data center storage. While both companies benefit from AI storage demand, what investors ultimately need to determine is whether the better allocation choice is a diversified platform or a pure-play NAND cyclical stock offering higher elasticity.
