Overview
- SK Hynix briefly overtook Samsung on Monday when its market value reached about 2,082.5 trillion won compared with Samsung's roughly 2,081.3 trillion won, according to stock-market data.
- Shares of SK Hynix rose about 5.7% while Samsung shares climbed roughly 0.4% on the move that produced the short-lived market-cap shift.
- The rally is tied to strong orders for high-bandwidth memory from AI data-centre builds that have tightened supply, pushed up prices and helped South Korean memory firms report record profits.
- Analysts warn the re‑rating may not stick because the memory industry is cyclical and will be tested by heavy capital spending to add capacity plus upcoming earnings and factory rollouts.
- Investor exposure to SK Hynix is currently concentrated because U.S. retail access has been limited, so listings, ADR filings and ETF flows will shape how broadly this valuation change matters to global investors.
