As Samsung’s Quarterly Profits Soar, Shares Sink

By the Editorial Team · Wednesday, July 8, 2026

Samsung Electronics reported a nearly 20-fold increase in its second-quarter operating profit to 89.4 trillion won ($58 billion), driven by strong demand for memory chips used in AI data centers. This surge underscores the critical role of AI infrastructure in boosting semiconductor earnings, though investor concerns about market concentration and volatility led to a 7% drop in Samsung’s shares despite robust growth.

Samsung Electronics reported a surge in its second-quarter operating profit, reaching 89.4 trillion South Korean won (approximately $58 billion), nearly 20 times higher than the same period last year. The South Korean technology giant attributed the jump to strong demand for memory chips, particularly those used in data centers supporting artificial intelligence (AI) applications. Revenue for the quarter also more than doubled year-over-year, reaching about $112 billion.

The company’s results highlight the growing impact of AI-driven investments in computing infrastructure, which continue to drive earnings for memory chip manufacturers to unprecedented levels. Despite the robust financial performance, Samsung’s shares declined 7 percent in Seoul following the announcement, reflecting elevated investor expectations. Nonetheless, Samsung’s stock has more than doubled in value this year amid broader enthusiasm for AI-related technology companies.

South Korea’s benchmark stock index, the KOSPI, recently set multiple records and has outperformed major global markets. Over the past year, the index has more than doubled in value, with analysts at Goldman Sachs attributing nearly 90 percent of those gains to Samsung and SK Hynix, another leading South Korean memory chip maker. Both companies achieved market valuations exceeding $1 trillion this year. However, analysts warn that the market remains highly concentrated, increasing volatility risks linked to the semiconductor sector.

Tuesday saw the KOSPI drop 5 percent, led by losses in Samsung shares. The underlying driver of the sector’s strong performance remains the constrained supply of high-bandwidth memory chips, essential components for training advanced language models and operating energy-efficient data centers. Ongoing robust demand has allowed Samsung, SK Hynix, and other producers to raise prices while maintaining substantial profit margins.

In a related development, SK Hynix launched a U.S. share offering valued at up to $28 billion, which would rank as the second-largest share issuance in history, following SpaceX's recent $86 billion public offering. Industry observers, including Sanjeev Rana of CLSA, expect the tight supply of high-bandwidth memory chips to persist through at least 2028, when new semiconductor fabrication facilities now under construction are projected to come online and expand production capacity.

South Korea currently manufactures about 60 percent of the world’s memory chips, solidifying the country’s dominant position in the global semiconductor market. Yet concerns remain that the financial gains from this surge are concentrated among a limited number of firms, such as Samsung, with limited broader economic benefits.

Earlier this year, Samsung preemptively averted a strike in its semiconductor division by agreeing to offer employees, including assembly-line workers, a potential bonus of up to $400,000 next year, contingent upon meeting specific profit targets.
