On the news front, the memory chip pricing upcycle continued to intensify. DRAM and NAND contract prices surged 20-30% quarter-over-quarter in Q3, while hyperscale customers have reportedly signed agreements accepting further price increases for Q1 next year. Bank of America raised its DRAM average selling price forecast for the next two years by 8-12% and NAND by 2-3%, projecting a global memory TAM of $2 trillion by 2030 with a 21% CAGR through the period. Meanwhile, DRAM spot prices continued strengthening in the second week of September, with DDR5 module prices rising over 2% weekly and enterprise SSD prices remaining firm.
