The rapid growth of AI model training and inference is driving a new wave of value re-rating across the global memory and storage industry. Unlike previous storage cycles that were primarily driven by price fluctuations, the current upcycle is being fueled by structural demand growth stemming from AI infrastructure expansion. The rising importance of high-end storage products such as High Bandwidth Memory (HBM), high-capacity DDR5, and enterprise SSDs is transforming storage from a supporting component within computing systems into a critical resource that directly impacts model performance and deployment efficiency.
Key Takeaways:
- The global memory and storage sector has experienced explosive growth in market value, with the industry's three leading players—Samsung Electronics, SK hynix, and Micron Technology—all surpassing the $1 trillion market capitalization milestone.
- Continued growth in AI model training and inference workloads is significantly increasing both the demand intensity and value contribution of storage products, including HBM, DDR5, and enterprise SSDs, within data centers.
- Micron Technology recently joined the trillion-dollar market capitalization club, becoming one of the most closely watched beneficiaries of the AI storage value-chain re-rating. According to StockAnalysis data, Micron's market capitalization reached approximately $1.17 trillion as of June 3, 2026.
- The current rally in the storage sector is not simply a traditional DRAM cycle rebound. Instead, it reflects the market's revaluation of the structural value embedded in AI servers, HBM, long-term supply agreements (LTAs), and persistent supply-demand tightness across the storage industry.
- Gate has officially launched stock trading services, allowing users to trade stocks and ETFs from major global securities markets directly using USDT. The platform has also introduced stock perpetual futures with USDT settlement and 1x–20x leverage for both long and short positions.
