Samsung Electronics hit a historic milestone Wednesday, crossing the $1 trillion market valuation threshold. Its stock surged more than 15 percent in a single trading day, riding waves of global demand for artificial intelligence chips.
It was the company's biggest single-day gain ever. Samsung now sits alongside a select group of tech giants cashing in on the worldwide AI investment frenzy.
Only TSMC, the Taiwanese chipmaker, had previously achieved a $1 trillion valuation among Asian firms. Samsung's breakthrough underscores how semiconductor makers are becoming central to the AI revolution.
The rally came on the back of blockbuster first-quarter results. Operating profit hit 57.2 trillion Korean won—more than eight times the prior year's figure.
Revenue climbed to an all-time high of 133.9 trillion won. The numbers reflect how dramatically AI demand is reshaping the global semiconductor landscape.
Much of Samsung's growth stems from surging orders for high-bandwidth memory chips. These components let AI processors rapidly shuffle and process massive datasets for training and deploying AI models.
Tech giants like Nvidia, Google, and Microsoft are pouring billions into AI data centres. That spending is creating voracious appetite for memory chips across the industry.
"There is a tremendous shortage in DRAM and NAND memory chips due to torrid AI demand," noted Yu Jing Jie, a technology equity analyst at Morningstar.
DRAM temporarily stores data during processing tasks. NAND chips provide permanent storage, and both are vital for AI servers and cloud systems.
Building new semiconductor factories takes years and costs billions of dollars. Analysts predict chip shortages will persist for several years as capacity struggles to catch up.
Samsung faces stiff competition from SK hynix in the HBM market. SK hynix controls roughly 55 percent of the sector, while Samsung commands about 25 percent.
Samsung announced earlier this year that it had begun mass-producing HBM4 chips. These represent the newest generation of memory technology designed for advanced artificial intelligence systems.
According to the company, customer shipments have already started. Samsung hasn't revealed which clients are receiving the chips.
Industry observers expect Samsung's HBM4 chips to power Nvidia's upcoming Vera Rubin AI systems. Those platforms target next-generation data centre deployments worldwide.
Investor enthusiasm also spiked following reports of Apple's discussions with Samsung and Intel. The possibility of Samsung manufacturing chips for Apple boosted market sentiment around the company's prospects.
South Korea's broader stock market benefited from the AI rally. Its Kospi index climbed above 7,000 points for the first time in history.
SK hynix shares jumped more than 10 percent on the same trading day. The surge reflects how central memory chip makers have become to global tech growth.
Artificial intelligence is fundamentally reshaping the technology sector. Chipmakers now occupy the driver's seat in an investment cycle powered by data centres, cloud infrastructure, and generative AI applications.
Analysts believe memory chip producers capable of scaling advanced manufacturing will dominate the AI boom for years ahead. Competition among these firms will likely intensify significantly as demand grows.
