SK Hynix is considering an initial public offering for its U.S.-based Solidigm storage subsidiary as early as next year, according to a Reuters report cited by Stocktwits. People familiar with the discussions indicated that the business could seek a valuation as high as $150 billion and raise approximately $15 billion. The process remains preliminary, and neither the size nor the timing of an offering has been finalized.
Solidigm was created from the NAND flash memory and storage operations that SK Hynix acquired from Intel. The parent company paid $6.6 billion in December 2021 and a further $2.2 billion in March 2025, completing an $8.8 billion acquisition. Operating the acquired assets through a U.S. subsidiary gives SK Hynix a distinct enterprise-storage business alongside its broader memory operations.
A central part of Solidigm's offering is high-capacity enterprise solid-state storage. Its D5-P5336 product is marketed with capacities reaching 122.88 terabytes and uses NAND technologies including quad-level cell memory. Such products address data-center operators seeking to accommodate substantial volumes of information while limiting the physical number of storage devices required. AI and machine-learning workloads are among the applications identified in the supplied report.
A standalone public listing could give investors a direct market valuation for a NAND and enterprise-SSD operation currently held within SK Hynix. At the upper end of the reported valuation range, the offering would be unusually large for the semiconductor industry. The report compares the proposed figure with Arm's approximately $54 billion debut valuation in 2023 and Cerebras Systems' roughly $56 billion fully diluted public-market valuation in 2026. These comparisons describe reported valuations rather than establish what Solidigm will ultimately command.
The possible transaction arrives amid competition in NAND from Samsung Electronics, Kioxia, Micron and SanDisk. It also coincides with discussion of a potential Solidigm manufacturing investment in the United States. Reuters reported that upstate New York was under consideration for a NAND facility, which could diversify production beyond the company's Dalian, China operations. SK Hynix, however, said no specific plant plan had been confirmed.
The next concrete milestones would be a formal decision to pursue a listing, a disclosed offer structure and financial documentation detailing Solidigm's standalone performance. Until then, both the $150 billion valuation and the $15 billion fundraising figure should be treated as reported possibilities, not completed transactions.
