    Memory has grown to nearly two-thirds of AI chip component costs

    A recent analysis indicates that memory components, particularly High Bandwidth Memory (HBM), now constitute nearly two-thirds of the total cost for AI chips. This share has significantly increased from 52% to 63% between Q1 2024 and Q4 2025. Concurrently, the cost share for advanced packaging has decreased, while logic die costs remain relatively stable. The overall expenditure on AI chip components is projected to more than double from approximately $22 billion in 2024 to $52 billion in 2025, with HBM alone driving a substantial portion of this growth. AI

    IMPACT Memory costs are becoming the dominant factor in AI chip production, potentially influencing future hardware development and supply chain strategies.

    AI is killing the cheap smartphone

    The era of increasingly powerful and affordable consumer electronics, particularly cheap smartphones, is ending due to a global memory shortage. AI's massive demand for memory has led to a reallocation of these components away from consumer devices and towards data centers. This shift is causing a significant price increase and a projected 13% drop in worldwide smartphone shipments, disproportionately affecting lower-cost models and potentially limiting internet access for developing regions. AI

    IMPACT Consumer electronics prices are rising due to AI's demand for memory, potentially limiting access to technology for lower-income populations.
