SK hynix Inc. (NASDAQ:SKHY) stock rose more than 6% in Tuesday’s premarket session as investors continued to embrace the memory-chip maker’s U.S. listing and artificial intelligence narrative. Nasdaq futures gained 0.59%, while S&P 500 futures slipped 0.10%.
The gains extended the stock’s strong Nasdaq debut after the company completed a $26.5 billion U.S. listing. Market commentary suggested the ADRs priced at roughly a 3% premium to the Seoul-listed shares, a level viewed as within expectations given strong institutional demand.
While SK hynix’s U.S. debut was well received, its shares in South Korea fell sharply as investors locked in profits and weighed valuation concerns.
SK hynix ADRs Begin Regular Trading
SK hynix’s American depositary receipts began trading on the Nasdaq under the ticker SKHY on Friday, July 10, 2026.
The shares moved to regular-way trading on Monday after initially trading under the temporary ticker SKHYV.
The company priced the ADRs at $149. The stock opened about 14% higher at $170 and finished its debut session up 12.76% at $168.01, before adding another 2.43% in after-hours trading.
Meanwhile, SK hynix’s Seoul-listed shares fell 12.89% to 1.89 million South Korean won. A Reuters-cited analyst attributed the decline to profit-taking and a “correctional period” driven by the additional share issuance and valuation uncertainty.
Despite the pullback in Seoul, U.S.-listed ADRs continued to attract buyers as investors sought exposure to the company’s AI memory business. Market participants have also focused on SK hynix’s valuation relative to rivals such as Micron Technology Inc. (NASDAQ:MU).
The company is widely viewed as a leader in high-bandwidth memory (HBM), a critical technology used in AI accelerators and advanced computing systems. That positioning has helped strengthen investor interest in the new U.S.-listed shares.
Samsung Explores U.S. Listing Options
The strong reception for SK hynix’s Nasdaq debut has also fueled speculation that Samsung Electronics Co. Ltd. (OTC:SSNLF) could pursue a U.S. listing.
Bloomberg reported Tuesday that Samsung has begun preliminary discussions with banks about a potential U.S. initial public offering or ADR listing, although the company has not made a final decision.
Later Tuesday, Reuters reported that Samsung said it is not reviewing the possibility of issuing American depositary receipts, pushing back on the Bloomberg report.
