SK Hynix American depositary receipts (ADRs) are trading at a 50% premium to South Korean shares. The surge follows a record-setting $26.5 billion U.S. listing. This gap expanded significantly from the 3% difference recorded at the time of pricing.
Intense U.S. investor demand for the AI memory chipmaker is driving the price surge. Structural restrictions on converting Seoul-listed shares into ADRs prevent arbitrage traders from narrowing the price gap. The launch of U.S. options trading has further increased volatility and upward price pressure.
Analysts describe the price difference as a scarcity premium reflecting high demand for AI infrastructure chips. The market activity draws comparisons to the dot-com era due to intense appetite for key technology stocks. This persistent premium signals strong bullish sentiment from global investors who previously lacked direct access to the company.
