KEY POINTS
- SK Hynix (NASDAQ:SKHY) began trading on the Nasdaq today after raising about US$26.5 billion, the largest-ever US listing by a foreign company.
- The offering was around seven times oversubscribed, showing huge investor appetite for the AI memory leader and key Nvidia supplier.
- We see the listing as mainly about access: it lets global investors buy a stock that was previously hard to reach.
- Australians can get exposure two ways: the new US-listed shares, or the ASX-listed Global X Semiconductor ETF (SEMI), which already holds SK Hynix.
SK Hynix made its debut on the Nasdaq today, one of the biggest stock-market listings in history. (A quick note on the ticker: the shares trade under the temporary symbol SKHYV during conditional trading on Friday, switching to the permanent SKHY when regular trading begins on Monday, 13 July.)
The South Korean company raised about US$26.5 billion by selling new shares, and demand was so strong the offering was roughly seven times oversubscribed. For years, SK Hynix has been one of the most important companies in the AI boom, yet most global investors could not easily buy it. That just changed. Here is what it means, and how Australians can get in.
Why This Listing Is a Big Deal
First, why SK Hynix matters. It is the world’s second-largest memory chipmaker and the leader in high-bandwidth memory (HBM), the specialised chips that sit next to Nvidia’s processors and make AI systems work. It controls around 60% of that market, which makes it one of the most critical suppliers in the entire AI supply chain, ahead of rivals like Samsung and Micron in this key product.
Until now, its shares traded only in Seoul, in Korean won, out of reach for most foreign investors. That created what analysts call a “Korea discount”, the stock traded cheaply simply because so few global buyers could access it.
In our view, this US listing is less about the money raised and more about removing that barrier. As more investors can finally buy it, that discount could shrink, a bit like what happened when Taiwan’s TSMC listed in the US years ago.

How Australian Investors Can Buy SK Hynix
Here is the practical part for our readers. Australians have two main ways to get exposure:
First, you can buy the new US-listed shares (ticker SKHY) directly through a broker that offers US-market access, such as Stake, CommSec International, or Interactive Brokers. This gives you the purest exposure, though it involves a US tax form (a W-8BEN) and currency conversion.
Second, and often simpler, you can buy an Australian ETF that already holds SK Hynix. The Global X Semiconductor ETF (ASX:SEMI) is the standout: SK Hynix is its second-largest holding at around 9%, sitting alongside Nvidia and Micron. Because SEMI trades on the ASX, you get exposure to the AI memory giant without any US tax paperwork or currency conversion.
The Investor’s Takeaway for SKHY
So should you buy? SK Hynix is a genuine AI winner, sold out of HBM chips well into next year, and even after a huge run it trades at a lower earnings multiple than US peers like Nvidia. That is why some see it as one of the better-value ways to play AI hardware.
But there is a clear risk to respect. The memory-chip business is famously cyclical; it swings between boom and bust, and the shares are priced as though today’s boom will keep running. If AI spending slows and memory prices fall, the stock could drop quickly.
Our take: for long-term investors who believe the AI memory boom has room to run, SK Hynix is a high-quality way to play it, and for most Australians the ASX:SEMI route is the simplest entry. But given the stock’s huge rally and the cyclical risk, buying gradually on weakness makes more sense than chasing the excitement of day one.
