Now that SK Hynix (NASDAQ: SKHY) trades on the Nasdaq stock exchange, U.S. investors have a front-row seat to one of the most commanding positions in the entire artificial intelligence supply chain.
The South Korean company makes more than half of the world’s high-bandwidth memory — the specialized chips that Nvidia (NASDAQ: NVDA) needs to make its AI accelerators work
That kind of market grip is rare, and understanding it is the key to understanding why this stock matters. SK Hynix’s debut made it the largest first-time U.S. listing ever by a foreign company, after investor demand exceeded the shares available by more than seven times. The landmark IPO gives U.S. investors an easy way to buy one of the world’s leading AI memory chipmakers, but the stock’s strong debut doesn’t eliminate the need to evaluate its long-term investment prospects.
Why Nvidia can’t build AI chips without this memory Start with what high-bandwidth memory, or HBM, actually does. An Nvidia AI accelerator is only as fast as the data you can feed it, and ordinary memory can’t keep up. HBM solves that by stacking memory vertically and placing it right beside the processor, so information flows almost instantly.
