SK Hynix Inc. has surpassed a $1 trillion market valuation after shares soared more than 11% on Wednesday, according to latest reports. The company's stock climbed as much as 11% on Wednesday, making it the third Asian company to join the $1 trillion club after South Korean peer Samsung Electronics Co. hit the mark earlier this month. The Kospi index jumped 5% following the announcement, reflecting strong investor confidence in the memory chip sector as investors continued to pile into artificial intelligence-linked semiconductor stocks.
SK Hynix sits at the chokepoint of the global AI buildout, with memory chips emerging as a critical bottleneck determining how quickly data centers can expand capacity, as reported by Moneycontrol. Investors and analysts expect memory chip shortages to last through 2027, giving SK Hynix and rivals Samsung and Micron Technology Inc. unusual pricing power over the world's largest technology companies. In the fourth quarter of 2025, SK Hynix retained 57% of global HBM market share by revenue, with Samsung and Micron following at 22% and 21% respectively, according to Counterpoint Research's data. Micron's value also surged above $1 trillion this week, highlighting the sector's strong performance.
In April, SK Hynix reported a five-fold jump in quarterly profit, while anticipating that HBM demand will exceed supply in the next three years, according to Moneycontrol. Even with their rapid ascent this year, SK Hynix shares trade at six times one-year forward earnings, compared with 27 times for the Philadelphia Semiconductor Index. As noted by Taurus Asset Management's Cha So-Yoon, "Judging by earnings power alone, it's difficult to predict a near-term peak." Barclays analysts expect SK Hynix to remain the leader in high-bandwidth memory, with product pricing expected to remain favorable due to supply tightness.
SK Hynix has filed to list its American depositary receipts this year, which would rank among the biggest New York debuts by a foreign company, giving American investors another way to play the AI memory trade, as reported by Moneycontrol. Barclays analysts highlighted a potential US listing as a catalyst, with Barclays analysts including Simon Coles writing that "We expect SK Hynix to remain the leader on" high-bandwidth memory. "We've had an extraordinary move in semiconductor stocks since the late March lows, with memory stocks leading that surge," said Janus Henderson's Richard Clode, citing very strong AI demand driving record margins and now long-term contracts to make this cycle more durable.
