SK Hynix's American shares opened at $170 and closed their first Nasdaq session near $168, up about 13 percent from the $149 offer, with an intraday high around $176 [E1]. The debut valued the company close to a trillion dollars and capped the largest first-time US listing by a foreign company, a $26.5 billion sale that ran about seven times oversubscribed [E1][E2].
One product explains the reception. SK Hynix supplies the majority of the world's high-bandwidth memory, the chips bolted beside the AI accelerators in the data centres of the largest US cloud buyers, and it counts Nvidia among its customers [E2]. Buyers were not pricing a single chip; they were pricing the memory layer the whole build-out runs on [E2].
SK Hynix's own message was that the squeeze only tightens. Its leadership framed demand as enormous and warned that the memory shortage will deepen through 2027 as AI buyers lock in multi-year supply, while analysts pressed the case that SK Hynix should build new fabrication capacity on US soil [E2]. Scarcity, in other words, is the pitch as much as the product.
The debut settles a call the desk made yesterday. The Forecast Ledger had SK Hynix closing at or above its $149 offer at a probability of 0.6; the shares closed near $168, a clean hit, and the dissent that warned a June drawdown in the underlying could cap the pop was overrun [E1]. The market read the memory shortage as durable and priced it up.
The cautions survive the win. A first-day close is a mood, not a multi-year verdict, and the valuation still assumes an AI-memory cycle that holds through the glut that has ended every prior chip boom [E1]. The near-term tells are ordinary: whether SKHY keeps the gain when it becomes the permanent ticker on 13 July, and whether high-bandwidth-memory pricing stays tight into next year. For one session, the answer was emphatic [E1][E2].
