An initial public offering (IPO) by SK Hynix is expected to give US investors a larger stake in the memory market, which is currently experiencing shortages. The IPO has reportedly been oversubscribed, with some outlets suggesting it could be valued at around $26-28 billion. However, there are also reports of a slump in SK Hynix's value ahead of its US listing, potentially due to a downturn in the AI chip market.
