How to buy SK Hynix stock.
SK Hynix is the leading producer of high-bandwidth memory and Nvidia's primary HBM partner for its AI GPU platforms. HBM attaches directly to accelerator packages; without it, the fastest chips cannot feed data fast enough for large-model training. Since July 2026 it trades on Nasdaq as an ADR under SKHY, priced in US dollars, so mainstream brokers can now offer it alongside its original Korea Exchange listing.

What SK Hynix does.
SK Hynix is the world's leading supplier of high-bandwidth memory and Nvidia's primary HBM partner. It was first to market with HBM3 and HBM3E, the memory used in Nvidia's H200 and Blackwell platforms, giving it an outsized share of the highest-margin corner of the memory market during the AI build-out.
Beyond HBM, SK Hynix is a top-three producer of commodity DRAM and NAND (bolstered by its Solidigm/Intel NAND acquisition). Its earnings are highly geared to the memory cycle and to AI accelerator demand, which tends to lead GPU shipments by several months.
In July 2026 it listed ADRs on Nasdaq under SKHY, raising about $26.5B in the largest US share sale ever by a foreign company. That put a dollar-denominated line on a US exchange next to the existing Korea Exchange listing, making the stock reachable through ordinary US brokers rather than only international ones. The underlying business still earns in won, so currency moves feed through to ADR holders.

Why SK Hynix is an AI stock.
SK Hynix is Nvidia's preferred HBM supplier and was first to market with HBM3E, the type used in Nvidia's H200 and Blackwell. Its fortunes track AI capex cycles closely: when labs order more GPUs, HBM demand often leads by several months.
SK Hynix is in the Memory and HBM category. High-bandwidth memory is the bottleneck alongside compute. These suppliers ride every new AI training cluster build-out.

Frequently asked questions.
How can I buy SK Hynix stock?
SK Hynix trades on Nasdaq as an American depositary receipt under the ticker SKHY, priced in US dollars. Because it is a US-listed security, mainstream brokers including eToro and Robinhood can offer it, and no special international market access is required. The company's original listing (000660) still trades on the Korea Exchange in Korean won, reachable through Interactive Brokers or DEGIRO.
What is SK Hynix's ticker symbol?
SKHY on Nasdaq for the US-listed ADR, and 000660 on the Korea Exchange for the underlying common shares. During the first days after the July 2026 debut the ADR traded under the temporary symbol SKHYV, which is no longer in use.
When did SK Hynix list on Nasdaq?
SK Hynix listed its ADRs on Nasdaq on 10 July 2026, raising roughly $26.5B in the largest US share sale ever completed by a foreign company. The ADRs were priced at $149 and opened at $170. The Nasdaq listing is a secondary listing: the Korea Exchange line continues to trade as before.
Is SK Hynix a good AI stock?
SK Hynix is the leading HBM supplier, which is a critical AI component with a small number of suppliers. It benefits directly from Nvidia GPU demand. The main risks are memory price cycles, competition from Samsung and Micron, and the fact that the ADR still tracks a won-denominated business, so the exchange rate affects your return even though you buy in dollars.
