Robert Shiller on SK Hynix
SK Hynix’s HBM lead remains dated and concrete, but Solidigm’s shelved listing shows how share-price conditions can interrupt the financing story built around AI demand.
SK Hynix still supplies a precipitating factor for Shiller’s feedback framework. The company dossier dates its HBM3E volume production to September 2024, before Samsung’s limited clearance in January 2025. The dossier also records Nvidia allocating most of its 2026 HBM4 demand to SK Hynix while Samsung remained in qualification. Management’s forecast that demand would exceed supply past 2030, following its warning of a shortage in 2027, faces Shiller’s new-era test: does that lead mean the memory cycle has permanently changed?
Reuters reported Solidigm IPO talks in September 2026: SK Hynix’s subsidiary was exploring a listing as early as 2027 that could raise $15 billion and value the unit at up to $150 billion. The Wall Street Journal reported the halt on October 23. SK Hynix said Solidigm had stopped reviewing a potential US IPO to fund a US chip factory, citing “market conditions and share price trends.” The October decision replaces an explored financing route, not the dossier’s dated HBM production lead. Reuters had separately attributed to sources a factory condition: Solidigm sought US approval to export chipmaking equipment to its Dalian plant before building a US factory. Reuters did not establish approval or construction.
The provider-current Seoul series records SK Hynix’s October 23 close at KRW 1,277,000, up 4.42% from KRW 1,223,000 at the previous close. TEXXR counted 55 articles about SK Hynix in 2026 Q3, its latest complete quarter, compared with 11.8 articles per quarter across the preceding eight quarters. Those figures count published coverage, not memory shipments or recruited buyers.
Shiller’s naturally occurring Ponzi process requires a fuller sequence: rising prices, contagious explanations, new buyers and another price rise. The supplied record shows price movement, coverage and a company decision tied to share-price conditions; it does not identify buyers recruited by the story. The materials also lack the decade of real earnings needed for Shiller’s cyclically adjusted valuation test. SK Hynix’s operating lead remains supported, while the permanent-cycle claim and the complete feedback loop remain unproved.
