SK Hynix is already worth over $1 trillion.
Its stock is up more than 800% in the past 12 months.
And now it wants a piece of the US market.
The Korean memory chip giant just filed plans for a $29 billion US listing - one of the biggest first-time share sales ever. The stock shot up 12% in early trading Thursday before settling around 8% higher, according to Bloomberg.
SK Hynix sits at the center of the AI supply chain. It's the leading maker of high-bandwidth memory - the kind of chips that power advanced AI systems.
That product is the reason its stock has gone vertical.
But global investors have had a hard time getting direct access. A US listing changes that.
ADRs are basically a way for foreign companies to trade on US exchanges. You buy them through a regular brokerage account, just like any American stock.
For SK Hynix, that means a whole new pool of investors who couldn't easily buy its Seoul-listed shares before.
The company plans to use the cash for more factory space and extreme ultraviolet lithography machines - the expensive equipment that prints circuits onto chips. More capacity means more high-bandwidth memory to sell into a market that can't get enough of it.

Here's the number that explains why SK Hynix wants this listing.
In Seoul, the stock trades at 7.5 times forward earnings. Samsung sits at 6.7 times. Compare that to TSMC at 21 times and Micron at 9.5 times - and you can see the discount.
A US listing could help close that gap. TSMC's ADR has traded in the US since 1997, and it commands a premium partly because American institutions can buy it easily.
More visibility, more accessibility, and more institutional ownership tend to push valuations higher.
"A liquid US listing could help reposition SK Hynix alongside global semiconductor leaders," said Aadil Ebrahim, group head of equities at Klay Group.
The ADRs are expected to start trading July 10. The real question is execution - whether SK Hynix can actually build the capacity it's promising and hit its production targets in the US.
There may be some back-and-forth between the ADR price and the Seoul-listed shares as traders arbitrage the difference. But analysts mostly see that as a positive - more liquidity and better price discovery, not dilution.
A $29 billion listing says SK Hynix is betting the AI boom has a long runway.
