Samsung’s Profit Surges 160% as AI Chip Demand Powers a Major Comeback

Samsung has posted a major rebound in its third-quarter results, showing that the chip slump may finally be behind it. The company reported revenue of 86.1 trillion won for the quarter ended September 30, 2025, with operating profit jumping to 12.2 trillion won. That’s about a 15.4% revenue increase quarter-on-quarter and an operating profit roughly 160% higher than the previous quarter. 

The key driver? its semiconductor division. The Device Solutions segment delivered record quarterly revenue of 33.1 trillion won and an operating profit of 7.0 trillion won thanks to soaring demand for high-bandwidth memory (HBM) chips used in AI systems. Samsung says its HBM3E is in mass production and its next-generation HBM4 is already being sampled by top clients. 

What this means is significant. Samsung’s turnaround shows just how vital memory-chip supply is to the broader AI infrastructure build-out. With companies like OpenAI, Microsoft and others ramping up compute, the holes in memory supply are starting to plug and pricing is improving. In short, Samsung is capitalising on the shift rather than being left behind.

Smartphones and consumer hardware also contributed. The Mobile eXperience division posted solid growth in revenue and profit thanks to strong flagship smartphone and foldable device launches. But clearly the semiconductor story stole the spotlight. 

Looking ahead, Samsung is optimistic. It expects demand from AI infrastructure and servers to keep its chip business strong. It plans to expand production of advanced memory products and scale the HBM4 business in 2026 and beyond. 

Still, this isn’t a signal that all is easy. The industry is competitive, supply chain and export dynamics remain complex, and sustaining this momentum will require both investment and execution. For Samsung the question now is not just “can it bounce back?” but “can it stay ahead in the AI memory race?”

Samsung’s Q3 results are a strong signal. Memory chips, long considered a commodities business, are becoming strategic differentiators. And companies that control them may be better positioned for the next wave of AI-driven growth.
