The Science and Technology Innovation Chip ETF rose by 4.73%, the Integrated Circuit ETF by 3.82%, the Chip ETF by 3.71%, and the Semiconductor Equipment ETF by 3.48% [2][3] AI and Storage Market Dynamics - Due to the AI demand, major overseas manufacturers are shifting their production capacity towards DDR5 and HBM, leading to a supply-demand mismatch and price increases for DDR4 and other products. From Q2 2025, mainstream storage product prices have been rising quarter-on-quarter, with NAND Flash prices also increasing. The price hikes are expected to continue due to sustained AI demand, potentially exacerbating the tight supply situation through 2026 [6][8] Electric Grid Sector Opportunities - The electric grid sector is poised for historical opportunities, driven by the increasing power demand from AI data centers. The U.S. is projected to face a power shortfall of approximately 73.2 GW from 2025 to 2030, which could rise to 201 GW if data center growth exceeds expectations. This situation may lead to new opportunities for domestic electric grid companies, particularly in the context of power exports [11][12]
