On July 27, 2026, the Kospi attempted a rebound after plunging nearly 6% last week and breaching the 7,000-point level, powered by a massive $950 billion (approximately 1,390 trillion won) artificial intelligence (AI) partnership between South Korean and US companies. In pre-market trading on July 27, Samsung Electronics (005930) and SK Hynix (000660) surged 3-4%, with Samsung Electronics trading at 258,500 won, up 9,000 won (3.61%), and SK Hynix rising 74,000 won (4.21%) to 1,833,000 won. Both stocks had plummeted 7.59% and 8.34%, respectively, on July 24. The spark was ignited at the 'AI Summit' in San Francisco, held on the occasion of South Korean President Lee Jae-myung's visit to the United States, where Samsung Electronics and SK Group formalized supply chain cooperation with Nvidia, Broadcom, and Microsoft. Samsung Electronics signed a strategic Memorandum of Understanding (MOU) with Broadcom valued at $200 billion (approximately 290 trillion won) through 2030, a 'one-stop turnkey solution' contract encompassing advanced memory like High Bandwidth Memory (HBM), contract manufacturing of AI chips using sub-2-nanometer (nm) foundry processes, and advanced packaging.
