Key points
- SK Hynix plans to list American depositary shares on the Nasdaq under the ticker SKHY, tentatively debuting Friday, July 10, 2026, though the company itself calls that date subject to change.
- The offering could raise close to $29.4 billion, which would make it the largest ADR listing in history, bigger than Alibaba's 2014 New York debut.
- The old unsponsored OTC ticker, HXSCL, is not a live way to buy in anymore. Once SKHY starts trading, any standard US brokerage account will be able to buy it like any other US stock.
One of the biggest listings of the year hits Wall Street this week, and most American investors already know the name even though they have never been able to easily own the stock. SK Hynix, the world's second largest memory chipmaker, is preparing to list on the Nasdaq under the ticker SKHY. Here is what is actually happening and how you can buy in once it goes live.
What SK Hynix is actually doing
SK Hynix already trades in South Korea on the Korea Exchange under the ticker 000660. The stock has been on an absolute tear there, up roughly 280% so far in 2026 on soaring demand for the high bandwidth memory chips that power AI data centers. SK Hynix is not going public for the first time here. What is happening this week is a Nasdaq listing of American depositary shares, a structure that lets a foreign company's stock trade in dollars on a US exchange.
What makes this one historic is the size. SK Hynix is looking to raise somewhere around $29.4 billion by issuing new shares through the offering. That would make it the largest ADR listing ever recorded, bigger than Alibaba's $21.8 billion debut on the NYSE back in 2014 and bigger than Saudi Aramco's $25.6 billion IPO in 2019. That is a wild number for a stock most American brokerages could not even touch a month ago. The company says the money is earmarked for building out its Yongin and Cheongju chip clusters and buying the extreme ultraviolet equipment needed to keep up with AI memory demand. Read that as a growth raise, not a sign that insiders are looking to cash out.
The mechanics: ticker, ratio, and timeline
Under the current plan, each American depositary share represents one tenth of one SK Hynix common share, so 10 ADSs equal one Korean-listed share. Based on pre-offering estimates, that puts the expected price around $165 per ADR, though nothing is locked in yet. Here is how the next few days play out. Institutional bookbuilding runs from Monday, July 6. SK Hynix and its underwriters set the final price the evening of Thursday, July 9. Trading is expected to open on the Nasdaq the next morning, Friday, July 10. SK Hynix has flagged that all of these dates could still shift, and in a deal this size, they sometimes do.
This stock has also been genuinely wild lately. It fell nearly 15% one day last week and then rebounded almost 11% the next. Whatever price gets locked in on pricing night, go in knowing you are buying a stock that can swing double digits in a single session.
How to actually buy it
Here is the part that matters most if you are trying to get in. Before this Nasdaq listing, the only way most US investors could touch SK Hynix was through an unsponsored, over-the-counter ticker called HXSCL. That route is not usable right now. As of this week, HXSCL shows up as an inactive instrument on trading platforms. That is normal. OTC market makers typically pause an existing unsponsored ADR right around the time a company completes a proper sponsored listing on a major exchange like the Nasdaq.
Once SKHY begins trading, assuming the Friday timeline holds, you can buy it through any standard US brokerage account the same way you would buy Apple or Microsoft. You will not need international trading permissions or a workaround ticker. That is the whole point of a Nasdaq listing. It opens the stock up to ordinary retail brokerage accounts that could never easily hold Korean shares directly.
A few practical notes for the first days of trading. Newly listed stocks, especially ones this big and this hyped up, tend to swing hard in the first few sessions while the market figures out where it wants to price them. If SK Hynix prices its ADRs at a discount to build in demand, as many large offerings do, the stock could pop on day one, but that is never guaranteed. One more wrinkle for anyone new to ADRs: the price is set in dollars, but it tracks a stock priced in Korean won. Over time, that means the ADR reflects two things moving at once, how the business is doing and where the won sits against the dollar.
Why this listing is such a big deal
SK Hynix sits right at the center of the AI trade alongside Micron (MU), the two companies that dominate the high bandwidth memory chips used in Nvidia's AI accelerators. We already covered how Micron beat earnings by a mile and the stock fell anyway, proof of just how much of the AI memory story is already priced into these names. A Nasdaq listing gives SK Hynix a much larger pool of US investors and index funds that can now own it directly. Some analysts think the dollar listing could eventually trade at a premium to where the Korean shares sit today. If you already own Micron and have been watching the memory trade from the sidelines otherwise, this is the moment it gets a second US-listed way to play.
The bottom line
If the timeline holds, SK Hynix starts trading on the Nasdaq under SKHY this Friday, July 10, capping off the biggest ADR offering Wall Street has ever seen. The old OTC workaround is no longer usable. If you want in, the plan is simple: wait for SKHY to open for trading and buy it through your normal brokerage account like anything else on the Nasdaq. Just go in expecting real volatility. This is a hot, oversubscribed new listing, and the underlying shares have already been swinging double digits in a single day on their own.
This is not investment advice. Confirm the listing has actually happened and check the live price before placing any order, since the date and pricing are not final until SK Hynix and its underwriters lock them in.
