A memory maker's giant listing
SK Hynix plans a U.S. IPO that could raise $25 billion to $28 billion. If it hits the top of that range, it would rank as the second largest ever, behind SpaceX, then Saudi Aramco and Alibaba. The offering is seven times oversubscribed. Pricing points to about $149 a share, even though the stock has slipped into bear market territory.
The pattern here matches the earlier SpaceX IPO: strong, steady demand from investors for the leading companies pushing AI forward. Money keeps flowing to firms that build AI infrastructure, and there aren't many easy ways to invest in that build-out.
Why the demand is so hot
The spending numbers behind AI are enormous. Goldman Sachs recently estimated that over $1 trillion could go to AI capex next year. SemiAnalysis put out even bigger figures this week. On top of that, OpenAI announced new models the same day, and use cases keep growing on both the consumer and enterprise side. The core question is simple: how do you meet this demand, and which companies get the purchase orders needed to fill it?
There's a timing problem baked in. Raising, say, $26 billion has to turn into real, physical capacity later. Because building takes time, everyone has to invest now to serve demand that shows up in the future. That lag means more players will keep entering the field.
Capacity is tight across the whole data center stack. A year ago the talk was about needing more GPUs, and shortages there still exist. Nvidia remains the clear market leader, but buyers are broadening away from it. One example is Tensoray, a "neo cloud" data center company built around AMD chips instead of Nvidia. Wherever there are capacity limits, new suppliers and alternatives step in to fill them.
Where SK Hynix sits
Memory has become the new strategic asset inside the data center rack. SK Hynix holds 30% of a data center memory market that is expected to reach $1 trillion in spending this year on its own. The supplier shares: Samsung 34%, SK Hynix 30%, Micron nearly 18%. Everyone else holds 4% or less, a group that includes SanDisk.
The memory field keeps changing, moving from standard DRAM into high bandwidth memory, and looking ahead toward high bandwidth flash. SK Hynix has to prove it will lead that innovation while challengers push in from several directions and across categories, both in conventional DRAM and in flash storage. A fresh DRAM challenger, CXMT, is one to watch. Others coming up include Kioxia and SanDisk.
Every extra billion SK Hynix earns can be turned into new fab capacity and new product development. The memory build-out drives growth well beyond the chipmaker itself, feeding demand for fab equipment and advanced packaging. Proceeds from the listing would flow into fab investment that benefits partners like Applied Materials, which has an announced R&D partnership with SK Hynix. Recent reports also suggest SK Hynix may expand its packaging work beyond TSMC to include Intel.
Pricing power on its products is high. The open questions are how much more it can build, and where the new fab capacity will come online.
The volatility around it
The group has swung hard. Western Digital is down 8% this month. SanDisk has also sold off over the same stretch. The excitement earlier came from SK Hynix and Samsung working with South Korea, which put money in for AI growth. Then came worry that AI was priced to perfection. Even after Samsung posted strong numbers, investors stepped back.
