The impressive rally elevated the memory chip manufacturer’s overall market valuation to approximately 1,624 trillion won, equivalent to $1.08 trillion.
This achievement positions SK Hynix as South Korea’s second corporate entity to reach this prestigious valuation benchmark, trailing Samsung Electronics, which accomplished the feat earlier during the current month.
The timing proved particularly noteworthy as <a href="https://coincentral.com/micron-amd-and-marvell-rally-as-investors-look-beyond-nvidia/" rel="noopener noreferrer nofollow">Micron Technology</a> crossed the identical threshold just one day prior on Tuesday — marking an unprecedented moment where the globe’s three dominant memory chip producers simultaneously maintain trillion-dollar market valuations.
<blockquote>
 Dan Ives, managing director at Wedbush Securities, who incorporated SK Hynix into his IVES ETF on Tuesday, offered a straightforward assessment: “They’re in the winner’s circle.”

The synchronized rally among these three industry leaders stems from a singular catalyst: High-Bandwidth Memory technology.
HBM chips serve as critical components within artificial intelligence processors, with demand accelerating dramatically as AI training operations and inference workloads expand at unprecedented rates.
SK Hynix, Micron, and <a href="https://coincentral.com/samsung-stock-rises-as-workers-head-to-court-over-pay-deal/" rel="noopener noreferrer nofollow">Samsung</a> represent the limited number of manufacturers with the capability to produce cutting-edge HBM technology at industrial volumes, and their collective manufacturing capacity has been completely reserved through late 2026.
This severe supply constraint has enabled elevated pricing across the sector, directly enhancing profit margins for all three manufacturers.
Both SK Hynix and Samsung maintain strategic supply agreements with Nvidia, the market-leading provider of AI accelerator technology.
<h3 id="historic-month-for-memory-semiconductor-sector">Historic Month for Memory Semiconductor Sector</h3>
May 2026 has emerged as a watershed period for the memory chip industry.
Samsung achieved the $1 trillion valuation first. Micron reached the milestone on Tuesday. SK Hynix completed the trifecta on Wednesday.
SK Hynix now stands as the third Asian corporation to attain a $1 trillion market value, positioned behind Samsung and TSMC, which maintains its position as Asia’s most valuable enterprise with a valuation exceeding $2 trillion.
Concurrently, Micron has ascended to become the 11th-largest publicly traded corporation in the United States.
The stock has emerged as a pivotal catalyst in this year’s semiconductor sector momentum, contributing significantly to record-breaking performance in both the S&amp;P 500 and Nasdaq Composite indices.
SK Hynix shares have appreciated more than 248% year-to-date in 2026. Samsung has climbed approximately 165%, while Micron has advanced more than 210% during the identical timeframe.
These extraordinary gains follow an already impressive 2025, during which SK Hynix delivered returns exceeding 200%.
