Key Highlights
- Shares of SK Hynix surged more than 12% during Wednesday trading, achieving an all-time high and surpassing the $1 trillion valuation threshold
- The memory chip manufacturer becomes South Korea’s second company to achieve this milestone, following in Samsung’s footsteps
- This achievement came merely 24 hours after Micron reached the same valuation benchmark on Tuesday
- Industry-wide High-Bandwidth Memory chip supply constraints are expected to persist through the end of 2026
- Year-to-date performance shows SK Hynix shares climbing over 248% in 2026, adding to the previous year’s 200%+ gain in 2025
SK Hynix achieved a historic $1 trillion market capitalization milestone on Wednesday as shares skyrocketed over 12%, reaching an unprecedented high of 2.28 million won ($1,514.38).
The surge elevated the chipmaker’s aggregate market capitalization to approximately 1,624 trillion won, equivalent to $1.08 trillion.
This accomplishment positions SK Hynix as the second corporation from South Korea to enter the trillion-dollar territory, trailing Samsung Electronics, which reached this benchmark earlier in May.
The milestone occurred within 24 hours of Micron Technology achieving identical status on Tuesday — marking an unprecedented moment when the globe’s three dominant memory chip producers simultaneously maintain trillion-dollar market valuations.
Dan Ives, managing director at Wedbush Securities, who incorporated SK Hynix into his IVES ETF on Tuesday, put it succinctly: “They’re in the winner’s circle.”
High-Bandwidth Memory Shortage Drives Growth
The simultaneous rallies across these three industry giants share a common catalyst: High-Bandwidth Memory technology.
HBM components serve as critical elements within artificial intelligence processors, experiencing explosive demand growth as AI training and inference operations expand at unprecedented rates.
SK Hynix, Micron, and Samsung represent the limited group of manufacturers with capabilities to produce cutting-edge HBM chips at commercial volumes, with their entire production capacity already committed through late 2026.
This significant supply-demand imbalance has driven chip pricing upward, directly enhancing profitability for all three manufacturers.
Both SK Hynix and Samsung maintain strategic supply agreements with Nvidia, the leading provider of AI acceleration hardware.
Historic Month for Memory Chip Manufacturers
May 2026 has emerged as a transformative period for the memory semiconductor industry.
Samsung achieved the $1 trillion threshold first. Micron followed suit on Tuesday. SK Hynix completed this remarkable trifecta on Wednesday.
SK Hynix now stands as the third Asian-based corporation to attain a $1 trillion market value, positioning behind Samsung and TSMC, which maintains its status 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 principal catalyst behind this year’s semiconductor sector momentum, contributing significantly to pushing both the S&P 500 and Nasdaq Composite indices to new record territory.
SK Hynix shares have appreciated more than 248% year-to-date in 2026. Samsung has climbed approximately 165%, while Micron has advanced over 210% during the identical timeframe.
These impressive returns build upon an already robust 2025, when SK Hynix delivered gains exceeding 200%.
