SK Hynix’s market value surpassed Samsung’s at 2,082.5tn won following a 340% share rally this year driven by high-bandwidth memory sales to Nvidia and Google. Memory-chip peers Micron and Western Digital also hit record highs on AI-GPU demand, underscoring potential supply constraints that could affect Nvidia’s hardware costs and margins.
SK Hynix’s market capitalization rose to 2,082.5 trillion won after a 5.7% share gain, overtaking Samsung Electronics’ 2,081.3 trillion won valuation. The chipmaker’s 340% rally this year has been fueled by sales of high-bandwidth memory to Nvidia and Alphabet’s Google.
The shift underscores Nvidia’s reliance on SK Hynix as a key HBM supplier for its AI GPUs. Supply constraints or pricing power from SK Hynix could influence Nvidia’s hardware costs and profit margins in coming quarters.
Shares of Micron and Western Digital also reached record highs on robust AI-driven data center spending. Rising memory prices and tight inventories signal potential cost pressures across the semiconductor ecosystem.
