The gain capped a more than 340% rally this year, driven almost entirely by demand for high-bandwidth memory from Nvidia and other AI chip buyers. SK Hynix held 61% of the global HBM market in 2025, compared with 17% for Samsung and 21% for Micron. Samsung, for its part, contests the ranking, arguing that including preferred shares puts its cap at 2,246.4 trillion won.\n\nThe valuation flip is less a sudden upset than the payoff from a contrarian bet. SK Hynix kept investing in HBM through the 2023 memory downturn — when it posted a 7.73 trillion won annual operating loss — while Samsung reportedly ran into yield and qualification problems on its HBM3E chips that slowed Nvidia orders. Focus matters to investors too: SK Hynix makes memory and little else, whereas Samsung spans smartphones, displays, contract chipmaking, and appliances, diluting exposure to HBM's industry-leading margins.\n\nThe race is not over. Nvidia confirmed this month that all three major suppliers — Samsung, SK Hynix, and Micron — passed HBM4 certification for its Vera Rubin platform, and Samsung shipped the first 12-layer HBM4E samples in May. SK Hynix is projected to expand DRAM output by roughly 38% between 2025 and 2028 against Samsung's 17.5%, which would cut the current production gap from about 23% to under 10% — so the symbolic lead in market cap may prove easier to hold than the technical one.","[\"memory\",\"semiconductors\",\"ai\",\"hardware\"]","2026-06-23T10:30:00.000Z","2026-06-23T10:51:57.780Z","2026-06-23T10:52:07.210Z","published",null,[],"https:\u002F\u002Fcdn.xyz.onl\u002Farticle-images\u002Fsk-hynix-tops-samsung-on-south-koreas-stock-market.webp","hardware",[27,28,29,25],"memory","semiconductors","ai",[31],{"name":32,"url":33},"Tom's Hardware","https:\u002F\u002Fwww.tomshardware.com\u002Ftech-industry\u002Fsk-hynix-passes-samsung-as-south-koreas-most-valuable-company-on-hbm-demand",0,{"sections":36},[37,41,46,51,56,61,65,70,75,80,85,90,95,100],{"name":38,"slug":29,"count":39,"latest_published_at":40},"AI",499,"2026-06-23T12:40:07.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",139,"2026-06-23T08:20:08.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Deals","deals",109,"2026-06-23T13:53:51.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Policy","policy",94,"2026-06-23T13:42:39.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Consumer Tech","consumer-tech",81,"2026-06-23T13:00:00.000Z",{"name":62,"slug":25,"count":63,"latest_published_at":64},"Hardware",68,"2026-06-23T12:52:54.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",63,"2026-06-23T11:16:34.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Dev Tools","dev-tools",51,"2026-06-22T22:40:07.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Science","science",39,"2026-06-23T05:25:16.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",32,"2026-06-22T17:00:00.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"General","general",26,"2026-06-13T18:35:15.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Startups","startups",23,"2026-06-16T15:00:00.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",19,"2026-06-14T08:00:00.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
