Samsung vs SK Hynix: Which AI Memory Stock Is the Better Bet Right Now?

TLDR

• Samsung posted record Q1 2026 revenue of KRW 133.9 trillion and operating profit of KRW 57.2 trillion
• SK Hynix reported record quarterly profit with operating profit of KRW 37.6 trillion in Q1 2026
• SK Hynix leads in high-bandwidth memory (HBM) and is most closely tied to AI chip demand
• Samsung is more diversified across memory, foundry, mobile, and consumer electronics
• Analysts rate both stocks as Strong Buy, with SK Hynix holding a slight edge in consensus

Samsung Electronics and SK Hynix are South Korea’s two biggest memory chip companies. Both are benefiting from the AI boom, but they are doing it in very different ways.

Samsung reported record results for Q1 2026. Revenue hit KRW 133.9 trillion and operating profit came in at KRW 57.2 trillion. Its chip division drove the bulk of those earnings.

Samsung Electronics Co., Ltd., SMSN.L

The company also plans to invest more than KRW 110 trillion in 2026 on research and facilities. That is a serious commitment to holding its position in AI chips.

Samsung is not just a memory company. It also operates in foundry, mobile devices, consumer electronics, and displays. That diversification gives it more protection if one part of the semiconductor market slows down.

However, that same diversification means Samsung has more risks to manage. Reuters has reported on labor tensions and potential strike risks at its chip operations. Samsung is also still working to close the gap with SK Hynix in high-bandwidth memory leadership.

SK Hynix: The Purer AI Memory Play

SK Hynix posted its own record numbers in Q1 2026. Revenue reached KRW 52.5 trillion, operating profit was KRW 37.6 trillion, and net profit came in at KRW 40.3 trillion.

The company said it expects AI chip demand to exceed its manufacturing capacity. That suggests high-bandwidth memory supply remains tight, which supports strong pricing and margins.

SK Hynix is the name most closely associated with the current HBM boom. Its stock rallied sharply after AI spending signals from major US tech companies came through.

The company is also exploring a possible US stock listing. That move would give it more capital market flexibility and access to a broader investor base.

The trade-off is concentration. SK Hynix does not have Samsung’s level of diversity. Its performance is more directly tied to memory pricing and the durability of AI-driven demand.

What Analysts Think

Analyst views are bullish on both stocks. Investing.com data shows Samsung with a Strong Buy consensus from 37 analysts, including 36 buys. The average 12-month price target is KRW 274,603.

SK Hynix also holds a Strong Buy rating from 38 analysts, with 36 buys and 2 holds. Its average price target is around KRW 1,771,866.

The margin of difference is small, but SK Hynix edges ahead on analyst consensus.

Both companies are investing heavily to stay competitive as AI infrastructure spending continues to grow across the US and Asia.

Final Thoughts

Samsung is the pick for investors who want scale and a broader semiconductor platform. SK Hynix is the pick for those who want more direct exposure to AI memory demand and the HBM supply crunch. SK Hynix posted the stronger Q1 2026 net profit relative to its size, and its capacity constraints point to continued pricing power in the near term.
