# Seoul called SK hynix's Solidigm listing a breach, then underwrote $1.5 billion for its suppliers

> Korea's financial watchdog says the planned Solidigm float would breach overlapping-listing rules; hours later the state, SK hynix and four banks launched KRW2 trillion in supplier loan guarantees. The planned US factory, meanwhile, is conditioned on Washington's export licenses for the Dalian plant in China.

## The watchdog called the listing a breach

[SK hynix](https://theinference.org/markets/companies/sk-hynix), Korea's memory-chip maker and the leading supplier of the high-bandwidth memory that AI accelerators depend on, was told by its own regulator on October 19 that the New York listing it is considering for Solidigm would breach Korean rules. At a parliamentary audit, Financial Supervisory Service governor Lee Chan-jin said the watchdog and the Financial Services Commission had determined a US float of the NAND unit [would violate the country's overlapping-listing rules](https://finance.yahoo.com/markets/stocks/articles/korea-says-sk-hynix-solidigm-063333914.html) [1].

Those rules restrict a parent and a subsidiary both trading, because outside shareholders in a listed Solidigm would take a slice of profits that now flow to SK hynix [1]. The shares fell 2% to 1.247 million won while the KOSPI rose 0.8% [1].

Solidigm is the US NAND flash and solid-state drive unit SK hynix bought from [Intel](https://theinference.org/markets/companies/intel) for about $9 billion [2]. [Reuters reported on September 25](https://www.ksl.com/article/51628703/exclusive-sk-hynixs-solidigm-weighs-ipo-that-could-value-theunit-at-up-to-150-billion-sources-say) that an IPO as early as 2027 could raise $15 billion at a valuation of up to $150 billion, in what could be the largest-ever US semiconductor listing; TechCrunch's reporting runs smaller, near $10 billion at up to $100 billion [2][3]. [The parent trades in New York as SKHY](https://theinference.org/article/sk-hynix-fell-10-by-midday-on-an-unverified-nvidia-hbm4-rumor-the-shipment-record-contradicts), worth about $1.06 trillion, and its SEC filings show $34.9 billion of first-quarter revenue, up 191% on the year [4][5].

## Hours later, Seoul underwrote the suppliers

The same day, at SK hynix's semiconductor cluster center in Yongin south of Seoul, the company, the industry ministry, the state-run Korea Trade Insurance Corp. (K-SURE) and four commercial banks launched [up to KRW2 trillion ($1.5 billion) in loan guarantees](https://www.koreatimes.co.kr/business/companies/20261019/sk-hynix-govt-to-provide-15-bil-in-loan-guarantees-to-semiconductor-suppliers) for suppliers of semiconductor materials, parts and equipment [6][7]. SK hynix and the banks contribute a combined KRW100 billion of that; suppliers SK hynix recommends get higher loan limits, interest-rate cuts of up to 2.5 percentage points and guarantee terms extended from one year to three [6].

The scale runs past the headline number. Industry Minister Kim Jung-kwan said chip-sector support will exceed KRW5 trillion, inside roughly KRW10 trillion of state backing across industries by year-end [6]. The program is the largest single-sector package in the government's export-supply-chain push [6][7]. Seoul is closing one financing channel for SK hynix while opening another.

## The third switch sits in Washington

[On October 15 Reuters reported](https://techcrunch.com/2026/10/15/sk-hynix-bargains-for-chip-equipment-exports-to-its-china-facility-in-return-for-building-a-factory-in-us/) that Solidigm has made further US equipment licenses for SK hynix's Dalian NAND plant in China a condition of building a new US factory, with upstate New York the leading candidate site [3]. The US has since granted an annual license for sending chipmaking equipment to plants in China, after revoking the Dalian facility's special exemptions in September 2025 [3]. SK hynix says it is not expanding Dalian capacity and that the installation is authorized by the US government [3].

## The scarcity keeps the ramp worth underwriting

The shortage both governments are managing is real. [Micron](https://theinference.org/markets/companies/micron) chief executive [Sanjay Mehrotra](https://theinference.org/markets/people/sanjay-mehrotra) said last week's results came with "no line of sight to when supply and demand will return to balance" [4], Objective Analysis founder Jim Handy does not expect supply to catch demand before 2029 [8], and [Elon Musk](https://theinference.org/markets/people/elon-musk) this month called unnamed memory rivals' pricing "extortionate" [8]. Handy's caveat: the boom fades when AI spending slows, and nobody can say when [8].

## Nothing is decided, and reach is the question

SK hynix's answer is that "no matters have been determined" [9], and Lee left the rule's reach open: regulators are still reviewing whether a US subsidiary falls under Korean securities reporting rules at all, pending an authoritative interpretation from the Financial Services Commission [1]. The company's SEC disclosure promised a market update within three months of early September, so by early December [9]. The Q3 results land this month [4]. One day in Seoul produced $1.5 billion of state credit and a [question mark over up to $15 billion of equity](https://theinference.org/article/seoul-calls-solidigm-s-up-to-150-billion-nasdaq-ipo-a-rule-violation-sk-hynix-s-us-fabs-need-two-approvals).

## Takeaway

In one day Seoul both closed and opened financing doors for SK hynix: regulators called the Solidigm listing a rule breach, the state and four banks pledged $1.5 billion for suppliers, and the planned US factory still waits on Dalian export licenses.
