Samsung forecast to post record 106.1 trillion won Q3 operating profit on AI memory demand

Samsung's expected Q3 numbers show how strongly AI infrastructure demand now flows to the memory layer. The consensus forecast is 106.1 trillion won (about $79.1 billion) in operating profit, almost nine times the year-ago quarter. Preliminary results arrive October 8.

The driver is HBM. Every AI accelerator, from NVIDIA's Blackwell line to custom chips, needs stacked high-bandwidth memory, and supply has stayed tight. Samsung trailed SK Hynix in qualifying HBM with NVIDIA for much of the last cycle, so a record quarter would suggest it has largely closed that gap or is benefiting from broad shortages that raise prices across conventional DRAM as well.

The forecast fits a week full of compute-capital headlines. NVIDIA is nearing a $6 trillion market cap. SpaceX is reportedly seeking $40 billion to buy NVIDIA chips. AWS is warning that blocked data centers threaten the US AI lead. Memory makers are among the clearest second-order winners of that spending.

On the device side, Samsung recently said Galaxy AI should reach 800 million devices by the end of 2026, but the earnings story is overwhelmingly about data centers. Caveats: these are forecasts, not reported results, and memory is historically cyclical. Watch the October 8 preliminary figures, any HBM4 qualification commentary, and guidance on whether capex is accelerating.
