Samsung Electronics posted a record 89.5 trillion won ($62 billion) in operating profit for the June quarter, a more than 19-fold increase from a year earlier, as insatiable demand for AI memory chips powered the company's semiconductor division to carry the rest of its business.
The semiconductor engine
Revenue hit an all-time high of 171.5 trillion won ($119 billion). The chip division benefited from rising prices and higher shipments of high-bandwidth memory used in AI servers, offsetting an operating loss in mobile, TV and home appliances where component costs squeezed margins.
The market didn't cheer
Shares fell in Seoul this week alongside rival SK Hynix, which also reported record revenue of 60.5 trillion won ($42 billion) but missed profit expectations. Retail-driven volatility amplified the slide, but the deeper worry is whether the industry's aggressive capacity expansion, 800 trillion won ($554 billion) combined for a new chip hub announced last month, will ever earn its keep.
China's shadow looms
Pressure intensified on reports that a state-backed Beijing firm has begun mass-producing advanced immersion DUV lithography machines domestically, while ChangXin Memory Technologies' strong debut signaled rising Chinese competition. The two Korean giants currently supply roughly two-thirds of global memory chips.
What to watch
Samsung expects robust memory demand through year-end driven by AI infrastructure buildout and agentic AI adoption, with the market staying undersupplied. But the real test is whether the hundreds of billions in US partnerships unveiled during President Lee Jae Myung's San Francisco trip, spanning OpenAI, Anthropic, Nvidia and Broadcom, translate into durable pricing power or just another capacity cycle.
