SK Hynix began trading on the Nasdaq on Friday, raising $26.5 billion [1] during its U.S. listing.

The move places one of the world's primary memory chip suppliers at the center of the artificial intelligence infrastructure boom. By securing a direct foothold in the U.S. capital markets, the company aims to fund the massive scaling of high-bandwidth memory required for AI processors.

Chey Tae-won, chairman of SK Group, said the debut was a historical moment and a dream come true. The listing pushed the company's market capitalization to approximately $1 trillion [2].

Market reaction was positive on the first day of trading. Reports on the share price increase varied slightly, with CNBC reporting a 13% rise [3] and the Financial Express noting a 14% increase [4].

Chey highlighted the critical role of memory in the current technological shift. He said that HBM demand is growing exponentially [5] and that overall demand is enormous [6]. High-bandwidth memory is essential for the high-speed data processing that powers generative AI.

To maintain this momentum, SK Group plans to invest tens of billions of dollars [7] into AI. The company is currently studying potential sites for investment within the U.S. to strengthen its strategic position and supply chain stability.

This expansion follows a period of rapid growth for the parent company, SK Group, as it pivots toward a future dominated by AI-driven hardware. The chairman said that the world has entered the AI era, which necessitates a fundamental shift in how semiconductor companies operate and invest.

"This is a historical moment and a dream come true."

The Nasdaq listing and subsequent trillion-dollar valuation signal a shift in the semiconductor landscape, where memory providers are now as critical to AI viability as logic chip designers. By raising billions in U.S. capital and planning domestic investments, SK Hynix is insulating itself against geopolitical volatility while attempting to lock in a dominant share of the high-bandwidth memory market.
