SK Hynix's US-based storage-chip unit Solidigm is in early discussions with investment banks about a possible initial public offering (IPO) in the United States, according to a Reuters report. The listing could come as early as next year and might value the company at up to $150 billion, making it one of the largest chip debuts in recent memory.
Reuters, citing sources familiar with the matter, said Solidigm held pitch meetings with banks this week as it weighs a listing. The same sources suggested the offering could raise around $15 billion, though they cautioned that both the timing and the size could shift depending on market conditions. SK Hynix, the South Korean memory-chip giant, acquired Solidigm as part of its purchase of Intel's NAND memory business in 2020.
What is Solidigm?
Solidigm designs and sells NAND flash memory and solid-state drives (SSDs), the storage components used in data centers, personal computers, and increasingly in artificial intelligence (AI) servers. NAND memory is the non-volatile storage that retains data even when power is off, making it essential for everything from smartphones to enterprise cloud infrastructure.
The company operates as a subsidiary of SK Hynix, which is one of the world's largest memory-chip makers alongside Samsung and Micron. SK Hynix has been investing heavily in AI-related memory, including high-bandwidth memory (HBM), which is used in AI accelerators. Solidigm focuses on the storage side of that business, which has seen demand grow as AI models require massive amounts of data to be stored and retrieved quickly.
A blockbuster chip IPO
If Solidigm achieves a valuation near $150 billion, it would be a landmark for the semiconductor IPO market. For context, Arm Holdings, the British chip designer, raised about $54 billion in its 2023 Nasdaq debut, and AI-chipmaker Cerebras Systems had a fully diluted valuation of roughly $56 billion in its 2026 IPO. A Solidigm listing would dwarf both, underscoring the market's appetite for AI-related chip companies.
The potential IPO also comes at a time when the listing pipeline is showing signs of strain. As IPO jitters ripple through the listing pipeline, some companies have delayed or scaled back their plans. However, a deal of this magnitude could signal that investors are still willing to back large, profitable tech businesses, especially those tied to AI infrastructure.
Other recent listings have also drawn attention. For instance, SoftBank-backed Carro is weighing a Singapore IPO with a Nasdaq dual listing, and Lumen is moving its stock listing from the NYSE to the Nasdaq in October. These moves highlight the ongoing activity in the equity capital markets, even as some deals face headwinds.
What it means for investors
For everyday investors, a Solidigm IPO would offer a rare chance to own a piece of a major memory-chip business that is currently private. SK Hynix is already listed on the Korean exchange, but a US listing would give American investors direct access to a company that is benefiting from the AI boom.
However, the deal is still in its early stages. The company has not filed any paperwork with the US Securities and Exchange Commission, and the final valuation and timing could change. Market conditions, especially the appetite for new tech listings, will play a big role. If the IPO does happen, it could provide a clearer public price for a business that has been part of SK Hynix's broader AI strategy.
Investors should also note that memory-chip stocks are cyclical, meaning their earnings can swing with supply and demand. While AI demand has been strong, a downturn in the broader semiconductor cycle could affect Solidigm's performance. As with any IPO, there are risks, including the possibility that the stock could be volatile in its early days of trading.
For now, the news is a sign that the chip sector remains a hotbed of activity, with companies looking to capitalize on investor enthusiasm for AI. Whether Solidigm can achieve a $150 billion valuation will depend on the strength of its business and the market's mood at the time of the listing.
