Global leading AI chip high-bandwidth memory supplier SK Hynix has secretly filed for a U.S. listing, aiming to go public in the second half of 2026 with an estimated raise of $10 billion to $14 billion. This move is intended to narrow the valuation gap with global peers like Micron, as although SK Hynix plays a crucial role in the AI supply chain, its stock listed in Korea has traditionally been undervalued. The funds will be used for large-scale investments, including a $7.9 billion acquisition of ASML EUV lithography machines by 2027 to meet the surging memory demand driven by AI. SK Hynix's move has also prompted calls for Samsung Electronics to consider listing in the United States.
