Samsung Electronics announced preliminary April-June results on Tuesday, July 7, 2026, estimating a 19-fold jump in second-quarter operating profit to 89.4 trillion won ($58.44 billion). The record performance, driven by soaring AI memory demand, contrasted with a steep slump on the Seoul stock market over sustainability concerns.
The boom in artificial intelligence infrastructure continues to fill corporate coffers in South Korea, even as public markets register severe jitters. Samsung Electronics estimated its second-quarter operating profit at 89.4 trillion won ($58.44 billion) for the period spanning April to June. That figure represents a staggering 19-fold increase compared to the same period a year earlier, easily surpassing the company’s combined earnings over the previous three years. In a regulatory filing, the company reported a profit of 4.7 trillion won a year earlier.
Record-Breaking Profit Figures and Market Expectations
The preliminary figures released in regulatory filings exceeded consensus estimates. According to data cited from Yonhap, the anticipated operating profit beat market projections by 6.2%, marking a third straight record quarterly operating profit for the technology giant. Samsung estimated the operating profit for the April-June period at approximately 89,400 billion wons (51 billion euros), representing an increase of 1,810.3% over one year. Quarterly revenue is projected to climb 129% year-on-year to 171 trillion won (98 billion euros). Other reports indicate the quarterly turnover reached 171.490 billion wons (104 billion euros), up 130% year-on-year, with net profit multiplied by 14 to reach 71.620 billion wons (43 billion euros).
Samsung is one of the most important manufacturers of high-bandwidth memory (HBM), a technology essential for the functioning of generative AI, alongside South Korean rival SK hynix and the American firm Micron. In a press release, Samsung highlighted a new “record quarter” for its memory activity, which the company explains was made possible by a proactive response to AI-related demand, particularly concerning products destined for servers. Samsung further emphasized that the continuing upward trend in prices across the sector also contributed to these record results.
Stock Market Slump and Investor Anxiety Over AI Sustainability
Despite the historic earnings report, investors wiped more than $80 billion off its market value as shares dropped by as much as 10.1% before finishing down 6.9%. Competitor SK Hynix also saw its stock end down 6%, dragging the benchmark KOSPI index down 4.9%.
Albert Yong, a managing partner at Petra Capital Management, said that Samsung’s strong earnings were widely expected and had largely been priced in after its shares rallied ahead of the results. Analysts attributed the declines to lofty market expectations and worries that spending on AI data centers may slow down. The outlook for chipmakers has been clouded by concerns that U.S. tech giants may slow their infrastructure plans and curb chip demand.
Massive Domestic Investments
At the national level, the South Korean government unveiled a massive public-private initiative on June 29. Authorities outlined a colossal plan equivalent to more than 1,000 billion euros in total over ten years to construct advanced semiconductor factories and AI data centers. Within this framework, 800,000 billion wons (455 billion euros) are designated for the construction of four new factories by Samsung Electronics and its compatriot rival SK hynix in the relatively underdeveloped southwest region of Korea.

Expert Outlook and Long-Term Uncertainties
While short-term financial returns remain exceptionally robust, industry experts provide context on the scale of these results. Kim Dae-jong, a professor of management at Sejong University, stated that this estimation represents the largest quarterly operating profit in history, surpassing Nvidia. He further predicted in declarations to the AFP that if Samsung manages to maintain this level of performance, it could become the top manufacturing company in the world.

The strong global demand for advanced memory chips used in AI data centers is serving as a boon for major South Korean manufacturers, who are chaining record profits and stimulating the economic growth of their country. To prioritize the lucrative AI sector, semiconductor manufacturers are reducing their production of less advanced chips. Detailed final results are scheduled for publication at the end of the month.
