When South Korean billionaire Chey Tae-won rang the opening bell at the Nasdaq, it wasn’t just a celebration of a historic $26.5 billion U.S. market debut—it was the ultimate vindication of a 14-year gamble that almost everyone told him not to take.
By listing its American Depositary Receipts (ADRs) at $149 per share, the South Korean semiconductor giant pulled off the world’s second-largest share sale in U.S. history, trailing only SpaceX’s record-breaking IPO. For Chey, the chairman of SK Group, it marks a stunning transformation for a company that was once the underdog of the tech world.
The Long-Shot Bet on a Money Loser
To understand how massive this moment is, you have to look back to 2012. When SK Group first acquired Hynix, the move was met with heavy skepticism, even within Chey’s own conglomerate. At the time, Hynix was bleeding cash, weighed down by debt, and trailing far behind its domestic rival, Samsung Electronics, in both market share and technology. Memory chips were widely viewed as a brutal, capital-intensive industry prone to harsh boom-and-bust cycles.
But Chey had a different vision. Desperate to find a competitive edge, he and his newly appointed leadership team doubled down on an unproven, niche technology: High-Bandwidth Memory (HBM).
For over a decade, SK Hynix quietly poured massive amounts of capital into HBM, refusing to give up even when board members questioned the heavy spending.
Becoming the “Picks and Shovels” of the AI Gold Rush
That stubborn persistence paid off spectacularly when generative artificial intelligence exploded onto the scene. It turned out that the high-speed data processing required by AI-focused graphics processing units (GPUs)—like those made by Nvidia—desperately needed the exact HBM architecture SK Hynix had spent years perfecting.
Almost overnight, the niche chip became a scarce commodity. SK Hynix emerged as the world’s leading producer of HBM, effectively becoming the indispensable hardware supplier fueling the global AI boom. The partnership is so critical that Nvidia CEO Jensen Huang recently noted that the modern AI industry simply could not have developed without SK Hynix.
The Bittersweet Reality of Success
While Wall Street embraces the company’s New York listing to gain pure-play exposure to the AI hardware theme, the road ahead holds unique hurdles for both the company and its architect.
-
Oversupply Worries: Memory chips remain highly cyclical. With both SK Hynix and Samsung pledging hundreds of billions to construct new domestic chip plants, some market analysts fear the industry could eventually run into an oversupply glut if Big Tech pulls back on infrastructure spending.
-
Personal Turmoil: Behind the corporate triumph, Chey is currently locked in an acrimonious, multi-million-dollar divorce settlement lawsuit. The outcome of the legal battle has high stakes, with the potential to impact ownership structures within SK Group, South Korea’s second-largest conglomerate.
Yet, despite the looming industry cycles and personal legal battles, Chey’s legacy is firmly cemented. The businessman once publicly criticized for buying a struggling, debt-laden chipmaker has engineered one of the most spectacularly successful contrarian bets in modern corporate history.
