Samsung made billions of dollars and regained its top spot in this market

2025, the second half in particular, has been great for Samsung's bottom line. The company has benefitted immensely from the rise in memory chip prices and demand.

It had been lagging behind its biggest rival but as its fortunes turned, not only did the company make billions of dollars, it also ended up retaking the top spot in the global DRAM market.

Samsung provided a bonkers earnings guidance for Q4 2025 today. The company estimates revenue for the quarter to cross $64 billion with profits reaching $13.8 billion. The turnaround in the memory segment is thus on track to deliver a 3x jump in its profits compared to Q4 2025.

The latest data from Counterpoint Research shows that Samsung's memory chip sales jumped 34% in Q4 2025 compared to the same period last year, hitting $25.9 billion, split into $19.2 billion for DRAM and $6.7 billion for NAND memory chips. Analysts estimate that nearly 40% of Samsung's projected $64 billion Q4 2025 revenue was generated by memory chips.

This stellar performance has enabled Samsung to regain the top spot in the global DRAM market. It lost this spot to SK Hynix in Q4 2024 for the first time in 30 years. SK Hynix came in second place behind Samsung in Q4 2025, with total memory chip sales of $22.4 billion.
