The memory-chip maker’s strong debut suggests investors are not abandoning the AI trade. They are becoming more selective about which parts of it they are willing to fund.

SK Hynix shares jumped nearly 13% in their NASDAQ debut, offering the clearest evidence yet that Wall Street’s appetite for artificial intelligence remains strong when a company controls an input the boom cannot easily do without.
The South Korean memory-chip maker’s American depositary receipts closed at $168.01 on Friday, up 12.8% from their offer price of $149, after opening at $170. The company raised $26.5 Bn in the largest US share sale by a foreign issuer, while investor orders exceeded the stock available by more than seven times. The receipts traded on a when-issued basis under the temporary ticker SKHYV, with regular trading under SKHY due to begin on Monday.
The reception matters because SK Hynix did not arrive in New York as an undiscovered AI bet. Its Seoul-listed shares had risen more than sixfold over the preceding year, driven by soaring demand for the high-bandwidth memory chips used alongside advanced AI processors. Investors were buying after an extraordinary rally, not before one.
Yet the debut showed that concerns over stretched AI valuations have not brought the broader trade to an end. Instead, capital appears to be concentrating on companies that control scarce, difficult-to-replace parts of the computing infrastructure.
SK Hynix occupies exactly such a position. Its high-bandwidth memory is a critical component in AI servers, feeding data rapidly to processors made by companies such as Nvidia. That gives investors a business whose exposure to the AI build-out can already be measured through chip shipments, pricing and earnings rather than promises of future demand.
The offering was the second-largest US share sale this year, behind SpaceX, and gives SK Hynix access to a much broader pool of American institutional capital. It could also help narrow the valuation gap with US-listed rivals such as Micron Technology, a key rationale for the overseas listing.
The strong debut does not settle the harder questions surrounding SK Hynix. Memory remains a cyclical business, Samsung Electronics and Micron are pushing to close the gap in advanced memory, and years of heavy AI spending could eventually create excess capacity. Nor does one day of when-issued trading establish whether the US-listed receipts will command a sustained premium or help rerate the company’s Seoul-listed stock.
Nevertheless, its high-bandwidth memory business is already generating measurable AI revenues. That, more than the promise of future demand, is what Wall Street now appears willing to pay a premium for.
