삼성전자, HBM4E 첫 출하로 AI메모리 시장 주도권 확보
Samsung Electronics closed at 317,000 KRW on May 29, 2026, up 17,500 KRW (+5.84%) from the previous day. The rally was driven by Samsung's announcement of the industry's first HBM4E sample shipments to global customers on May 28 (local time), signaling a competitive edge over SK Hynix in next-generation AI memory. The company's market cap has surpassed $2 trillion, reflecting upgraded valuations, as investors closely monitor HBM4E mass production timelines and Nvidia customer validation progress.
