SK Hynix Subsidiary Solidigm Weighs $150 Billion US IPO and First American NAND Fab

The outcome of SK Hynix's ambitious $150 billion valuation target for its Solidigm subsidiary will be determined not by product announcements, but by the "bake-off" pitch meetings held with investment banks this week. These underwriting discussions represent the first concrete step toward a 2027 initial public offering, and they will test whether Wall Street believes the artificial intelligence storage boom can justify a price tag that would make it the largest semiconductor IPO in US history.[1][4][7]

If the company hits its target valuation and raises the projected $15 billion, it would easily surpass the recent public debuts of Arm Holdings, which listed at $54.5 billion in 2023, and Cerebras Systems, which went public at $56.4 billion earlier this year.[4][6]

The staggering valuation target rests entirely on the sudden, insatiable demand for high-capacity enterprise solid-state drives (SSDs). Solidigm currently markets drives capable of holding 122.88 terabytes of data—hardware that allows data centers to physically cram more training data into fewer server racks.[6]

Yet, a $150 billion target is a massive leap for a business SK Hynix acquired from Intel for just $8.8 billion. That multi-phase transaction began in 2021 and only fully closed in March 2025. The rapid appreciation highlights how AI infrastructure buildouts have transformed the economics of NAND flash memory, a sector that recently endured years of steep losses during a prolonged cyclical downturn.[6][7]

To justify that premium and shield its supply chain, Solidigm is simultaneously moving to secure its manufacturing footprint. The company is evaluating sites in the eastern United States to build its first American NAND flash mass-production facility.[3][5]

Currently, Solidigm operates its headquarters in Rancho Cordova, California, and maintains research and development hubs stateside, but relies on a single fabrication plant in China for its NAND production.[3][5]

A US facility would fundamentally alter that equation. It would reduce the company's dependence on overseas manufacturing while limiting its exposure to potential US tariffs and tightening export controls on advanced chipmaking equipment.[3][5]

The proposed factory project is reportedly separate from SK Hynix's ongoing discussions with Intel to produce memory chips at Intel's planned Ohio facility. The push for domestic manufacturing aligns with the US government's broader effort to reshore semiconductor production, though SK Hynix must weigh the significantly higher costs of operating a fabrication plant in the United States compared to Asia.[3][5]

However, neither the IPO nor the factory is a finalized reality. SK Hynix representatives have confirmed only that Solidigm is "reviewing various measures to strengthen business competitiveness," noting that no specific plans have been confirmed.[3][5]

Building a US fabrication plant is notoriously expensive and slow, meaning any new capacity would take years to come online and would not immediately solve near-term supply constraints. The immediate test will be whether Wall Street underwriters believe the AI storage narrative is durable enough to support a $150 billion price tag.[1][6]
