Samsung Electronics reported a dramatic surge in profits for the fourth quarter of 2025, driven overwhelmingly by demand for AI-related memory chips, a shift that could have ripple effects across the smartphone market. The Korean giant’s operating profit for Q4 reached around 20 trillion won ($14 billion) more than three times what it earned in the same quarter a year earlier.
The jump in earnings came as prices and demand for DRAM, NAND flash, and high-bandwidth memory (HBM) surged, largely due to AI infrastructure buildouts around the world. AI servers require large quantities of memory with high bandwidth, and Samsung, as one of the world’s largest producers of these chips, has seen its memory business outperform all other divisions by a wide margin.
In particular, the memory division saw more than fivefold profit growth year-over-year, far outstripping Samsung’s smartphone and display units, which actually experienced shrinking margins amid rising component costs.
The AI memory boom means Samsung and other memory makers are prioritizing production for high-margin AI chips used in data centers and AI servers. With wafer space at a premium, this limits capacity available for more traditional memory products used in smartphones, PCs, and other consumer electronics.
Tighter supply and strong pricing for memory chips will likely keep component costs elevated into 2026, which could translate into higher prices for future smartphones. Even if manufacturers like Samsung want to absorb some of the cost rise, elevated prices for DRAM and NAND still push up the bill of materials (BoM) for new devices.
Analysts and industry observers note that memory chip prices have climbed sharply because AI infrastructure, especially HBM used for large models and server workloads, has become a premium product with limited supply. This has the indirect effect of squeezing supply for consumer markets while boosting profit margins for memory producers.
The current market environment means smartphone makers may face higher component costs, especially for memory and storage, which are key parts of flagship device pricing. Some reports already suggest that memory modules that cost around $25–$29 a year ago could now approach $70 or more for equivalent products, forcing makers to rethink pricing or specifications.
For companies like Samsung, Apple, and major Chinese brands, rising memory costs could push retail prices upward, particularly on premium models that demand the fastest memory and highest capacities from flagship Galaxy phones to next-gen iPhones and flagship devices across brands.
Samsung has also indicated that these conditions could persist into 2026, even as it prepares next-generation products like HBM4 memory and next-stage foundry technologies to cement its position in the AI chip market.
