Samsung Electronics and SK Hynix Rise on AI Semiconductor Demand Expectations

Samsung Electronics and SK Hynix are both experiencing strong gains in early trading, driven by expectations of increased demand for artificial intelligence (AI) semiconductors.


According to the Korea Exchange, as of 9:23 a.m., Samsung Electronics shares rose by 10,500 won (4.11%) to 266,000 won. SK Hynix shares increased by 9,500 won (5.77%) to 1,742,000 won.


The rise in both stocks is attributed to a surge in major memory semiconductor stocks in the U.S. market.


On September 4 (local time), the Philadelphia Semiconductor Index climbed by 3.38%. Key memory stocks, including SanDisk (up 11.90%), Seagate (up 6.34%), Micron (up 6.10%), and Western Digital (up 5.86%), all saw significant increases, while SK Hynix's American Depositary Receipts (ADRs) surged by 8.14%.


The strong performance of AI-related stocks is linked to the release of OpenAI's next-generation model, 'GPT-6 Astra.' This model reportedly enhances AI agent capabilities by combining search and program utilization to autonomously perform complex tasks.


As AI models become more advanced and their applications expand, there is growing anticipation that demand for memory semiconductors, including high-bandwidth memory (HBM), DRAM, and NAND, will increase alongside the rising computational and data processing needs.


Particularly, with ongoing investments in AI data centers, the demand for high-capacity and high-performance memory is expected to rise, potentially leading to an increase in memory prices. This has resulted in a surge of buying interest in domestic memory semiconductor companies, Samsung Electronics and SK Hynix.


Meanwhile, the market is looking forward to remarks from Jensen Huang, CEO of NVIDIA, at the Goldman Sachs Technology Conference scheduled for September 10 (local time), as well as Oracle's earnings report, which will be released after the market closes on the same day. These events are anticipated to confirm the ongoing trend of increased AI investment.
