SK Hynix Shelves Plans for a U.S. Listing of Its Solidigm Unit
SK Hynix has shelved plans for a possible U.S. listing of Solidigm, its memory-chip unit, citing market conditions, according to The Wall Street Journal, which reported the decision on October 23, 2026. The move ends, for now, a process that had been taking shape through the autumn.
Solidigm makes NAND flash, the storage used in solid-state drives (SSDs), which keep data without power. That is different from DRAM, the fast working memory that dominates the discussion around AI servers. An initial public offering (IPO) sells shares in a company to outside investors for the first time. The valuation set in that sale is the equity value buyers are willing to pay for the stake on offer.
In late September, Reuters reported that Solidigm was weighing an IPO that could value the unit at up to $150 billion and raise about $15 billion. Those two figures together imply the sale would have floated roughly a tenth of the company. The same reporting pointed to a listing as early as 2027.
The timetable then ran into a regulatory question. In mid-October, Reuters reported that South Korea had said a Solidigm listing could violate dual-listing rules. Those rules govern how a company already listed at home can also trade on a foreign exchange. They exist to keep a domestically listed business's value and governance within reach of local oversight. The specific provisions at issue were not spelled out, so the regulatory path should be treated as unresolved, not closed.
A separate thread points to the U.S. footprint. Reuters reported on October 14 that Solidigm was considering building a NAND flash chip factory in the United States. A plant and a listing are different decisions, but both would tie a Korean-owned chip business more closely to American capital and policy. The two appear to have moved in parallel, and the listing is the one now on hold.
The Wall Street Journal's account gives market conditions as the reason for the shelving. The up-to-$150 billion valuation and the $15 billion raise were reported as under consideration. They are not an expected price, and the decision attaches no new date for a listing.
In my view, the practical reading is narrower than the headlines suggest. For SK Hynix, the choice keeps Solidigm on its own balance sheet rather than turning part of it into a separately traded stock. For holders of SK Hynix and analysts tracking Korean memory names, no public price for the unit is scheduled. Anyone who wants a view on its value will have to build one from the parent's disclosures.
The broader context here is the order of events. A September valuation report, a mid-October regulatory objection and an October 23 decision to shelve form a cluster, and each step narrows the set of plausible near-term outcomes. Whether the listing returns in 2027, as the earlier reporting suggested, or later will depend on conditions and rules that the reporting has not yet resolved.
