SK Hynix Is $52 Billion Away From Becoming the World’s Next Trillion-Dollar AI Company
SK Hynix shares have surged over 200% in 2026 alone, on top of a 274% gain in 2025, pushing the South Korean chipmaker's market capitalization to approximately $948 billion.
Sixteen months ago, SK Hynix was worth less than $100 billion. Today, it is approaching the valuations of Walmart and Berkshire Hathaway. As Reuters reported, the South Korean chipmaker is nearing the $1 trillion market value milestone, a milestone Samsung Electronics crossed only weeks ago.
The global AI build-out is driving demand for high-bandwidth memory, triggering an intense AI memory squeeze that leaves neither SK Hynix nor its rivals able to manufacture hardware fast enough.
The story of how a memory chip company became one of the most valuable businesses on the planet is also the story of how AI infrastructure has become the defining investment theme of this decade.
Why HBM Is the Chip That Made This Happen
High-bandwidth memory (HBM) is not a product most people know, but it is what allows every AI accelerator, from Nvidia’s H200 and GB200 to Google’s TPU 7, to process the massive data loads required by large language models.
Unlike standard DRAM, which moves data sequentially, HBM stacks multiple memory dies vertically using through-silicon vias and places them directly beside the processor through advanced packaging.
The result is memory bandwidth up to ten times wider than conventional DRAM, a capability that makes modern AI inference at scale possible.
As Investing.com confirmed, SK Hynix controls roughly 57% to 62% of the HBM market, depending on the quarter, and has already sold out its entire 2026 production capacity.
Every Nvidia Blackwell GPU shipping this year contains SK Hynix HBM3E, while the company is preparing HBM4 for an H2 2026 ramp with advanced packaging support from TSMC.
While SK Hynix deepens its TSMC-linked AI ecosystem, Apple has reportedly held preliminary talks with Samsung to explore U.S. processor manufacturing as a backup to TSMC dependence.
The Numbers Behind the Ascent
The financial figures driving SK Hynix toward a trillion-dollar valuation are not incremental; they are structural.
As Reuters confirmed, Q1 2026 revenue surpassed 50 trillion won for the first time in company history, nearly tripling year-on-year. Operating profit rose fivefold, while operating margin reached 72%, an extraordinary figure for a capital-intensive chip manufacturer.
This margin surge is not isolated; Samsung Electronics recently mirrored the trend, reporting an eight-fold jump in Q1 2026 operating profit to 57.23 trillion won, largely driven by its memory division.
SK Group Chairman Chey Tae-won said in March 2026 that the global chip wafer shortage could persist until 2030, noting that expanding wafer capacity takes four to five years and that projected supply shortfalls may exceed 20%.
As Finimize confirmed, the broader KOSPI benchmark has surged through 2026, with IG analyst Fabien Yip describing markets as driven by “FOMO sentiments”, particularly around AI-related companies in Japan and Korea.
That optimism is tied to something tangible: Alphabet, Microsoft, Meta, and Amazon have signaled combined AI infrastructure spending above $700 billion in 2026, with memory chips forming a core part of every data center build.
The dynamic reinforces itself, the more AI infrastructure gets built, the more memory it requires, and the more companies like SK Hynix benefit.
What Comes Next and Where the Risks Are
The question is no longer whether SK Hynix will cross the trillion-dollar threshold; with HBM4 ramping in H2 2026, the remaining $52 billion gap appears manageable.
The bigger question is what happens next. Reuters noted that Samsung hit a record share price on the same day SK Hynix dipped slightly, reflecting investor rotation between the two Korean rivals.
Samsung has been rapidly closing the HBM gap after beginning HBM4 shipments to Nvidia in February 2026. Meanwhile, Micron is expanding HBM3E supply, supported by its $1.8 billion acquisition of Taiwan’s Tongluo P5 facility, giving AI chipmakers a third vendor option.
Bank of America named SK Hynix its global memory industry “Top Pick” for 2026, projecting 51% DRAM revenue growth and an HBM market worth $54.6 billion, up 58% year-on-year.
Goldman Sachs separately forecasts 82% growth in HBM demand for custom ASIC AI chips, which could account for one-third of the total market. SK Hynix’s 19 trillion won investment in a new domestic plant suggests it believes those forecasts are still conservative.
At a $948 billion valuation, SK Hynix has become one of the clearest indicators of what fully priced AI-era semiconductor demand looks like.
