SK Hynix, a memory maker, is reportedly going public in the US, with its initial public offering (IPO) valued at around $28-29 billion. This listing is expected to give US investors access to the company, which is seen as benefiting from the current AI boom. The development comes amid a surge in valuations of memory chip giants, including SK Hynix and Micron, which have crossed a $1 trillion valuation, although labor unrest at a competitor may impact memory chip supply.
