The $5.38 Billion ETF That Just Dethroned Tesla—And Why SK Hynix Can't Say Yes Fast Enough

A South Korean memory chip maker has quietly become the hottest ticket in global markets, and the offers flooding its boardroom are unlike anything the semiconductor industry has seen before. SK Hynix's shares hit a fresh all-time high of 1,680,000 won on Friday, extending a 148 percent rally since January that has turned the company into the centerpiece of the artificial intelligence hardware boom.

The scale of investor enthusiasm is captured in a single number: $5.38 billion. That is the assets under management now held by the CSOP SK Hynix Daily 2x Leveraged ETF, which on Thursday overtook the Tesla-linked TSLL fund to become the world's largest single-stock leveraged ETF. Since its listing in October 2025, the product has delivered roughly 750 percent returns—a figure that underscores just how voracious demand has become for the high-bandwidth memory chips at the heart of AI infrastructure.

Big Tech's Unprecedented Offer

The frenzy traces directly to a production bottleneck. SK Hynix reports that its available capacity for high-bandwidth memory is effectively zero. There is simply no room to allocate additional volumes to specific customers, and the crunch extends beyond HBM into conventional DRAM as well.

That scarcity has prompted an extraordinary response from the tech giants who need these chips most. Nvidia, Google and Amazon have all approached SK Hynix with proposals to finance entire production lines—including the purchase of ASML's extreme ultraviolet lithography systems, each costing between 300 billion and 500 billion won. The offers target in particular the first fab in the company's planned Yongin semiconductor cluster, a project with a total price tag of 31 trillion won.

Should investors sell immediately? Or is it worth buying SK Hynix?

Direct customer financing of this kind is virtually unheard of in the chip industry. Normally, manufacturers bear the capital expenditure risk themselves. But with AI buildout accelerating and supply locked up, the US tech titans are effectively trying to buy their way to the front of the queue.

Why SK Hynix Is Playing Hard to Get

The management team in Seoul is listening—but not rushing. SK Hynix has been exploring contract structures that involve down payments of 30 to 40 percent of order value, yet it remains wary of ceding too much control. Accepting outside financing could force the company to pledge future production volumes as collateral to individual customers, creating a dependency that would undermine its bargaining power down the road.

The first phase of the Yongin facility is not expected to begin operations until February 2027 at the earliest. Until then, the market stays tight. And SK Hynix can afford to be patient.

Record Numbers, Record Prices

The company's first-quarter 2026 results give it plenty of leverage. Revenue hit 52.5 trillion won, while operating profit surged to 37.6 trillion won. For the full year 2025, SK Hynix posted an operating margin of 49 percent—and for the first time ever, it surpassed archrival Samsung Electronics in operating profit.

Pricing power has been extraordinary. DRAM average selling prices jumped more than 60 percent in the latest quarter, while NAND flash memory prices climbed over 70 percent. The company now sits on liquid assets of roughly 54 trillion won, giving it ample room to fund its own expansion without taking outside money.

SK Hynix at a turning point? This analysis reveals what investors need to know now.

Goldman Sachs responded to the momentum by raising its target for the KOSPI index to 9,000 points, citing sustained AI hardware demand. JPMorgan lifted its price target for SK Hynix shares to 1.8 million won, while SK Securities sees fair value as high as 3 million won based on a price-to-earnings ratio of ten.

A Market Transformed

The memory chip industry has historically been among the most cyclical corners of the technology sector, prone to brutal boom-and-bust swings. What is unfolding now looks fundamentally different. Analysts point to structural AI demand as a force that could keep the market stable for years, and even competitors like Micron acknowledge that the current supply constraints go well beyond normal fluctuations.

The technical picture reflects the intensity of the move. SK Hynix's relative strength index sits just below 69, still shy of the classic overbought threshold, but the annualized 30-day volatility has climbed above 80 percent. Anyone waiting for a pullback has so far been left watching from the sidelines.
