Samsung shares fell more than 7% after CXMT announced a 4F2 DDR5 RDIMM for servers due by the end of 2026. The Galaxy S26 line's prices rose in October, and Samsung Display panels are what some Chinese iPhone buyers say they prefer.
Three stories from October 2026 put Samsung in different positions. The most recent is the sharpest: after CXMT said its first 4F2 architecture product would be a server DDR5 RDIMM due by the end of 2026, Samsung and SK hynix shares fell more than 7%. CXMT's vertical-transistor design cuts each memory cell's footprint by about one-third on paper and could fit 50% more cells, and no speeds or capacities were disclosed. The move puts CXMT into server DRAM rather than the consumer memory it has focused on.
The same cost pressure shows up in Samsung's phone pricing. The Galaxy S26 went from 136,400 yen to 155,800 yen on Samsung's official online store, and the S26+ and S26 Ultra were raised as well. The Pixel 10a rose at the same time, from 79,900 yen for 128GB to 92,800 yen. Carrier switching programs can still bring both devices down to a 33-yen burden.
Samsung Display sits on the other side of the ledger. A leaker's post describes Chinese iPhone buyers checking each year whether their display came from Samsung or LG, with some returning units until they get a Samsung panel. His rough user tier list for the iPhone 18 Pro series released September 18 placed Samsung's G9N and G9P above rival panels, while noting the rankings are impressions that vary by unit. Supply figures put Samsung and LG panels close in volume.

KB Securities analyst Kim Dong-won, in an October 20 report, said Samsung Electronics has locked in five-year supply contracts for about 70% of its general-purpose memory production for 2027, and full annual HBM output. Total contracted memory comes to roughly 80% of 2027 production. The report projects HBM average selling prices up 100 to 150% year on year in 2027 and DRAM prices up a double-digit percentage in the first quarter.
