The sell-off in AI stocks has intensified, driving South Korea’s stock market down to its lowest level in three months.
Investors continued to ditch chip stocks on Tuesday, amid rising concerns about the huge amount of borrowing among AI companies to fund their datacentre expansion plans.
The South Korean semiconductor companies SK Hynix and Samsung Electronics fell by more than 10%, dragging the country’s Kospi share index down by 11.5% to its lowest point since mid-April.
Analysts attributed the sell-off to renewed worries over AI investment spending, and competition from cheaper Chinese companies, after a report by the Information that China has begun mass production of homegrown deep ultraviolet (DUV) chip-making tools.
“We believe the market was likely spooked by the progress of China’s chip-making equipment capabilities, and was worried that this progress would threaten the competitive position of global chip making and chip equipment leaders,” said Jing Jie Yu, an equity analyst at Morningstar, adding that the sell-off was “largely a kneejerk reaction and overdone”.
On Monday, shares in the Chinese memory chip maker CXMT rose by 466% when it floated on the Shanghai stock exchange, underlining China’s drive to create its own AI supply chain.
Investors may also be growing jittery about the “circular funding” at the heart of the AI industry, through which artificial intelligence firms finance one another.
On Monday, the Wall Street Journal reported that Nvidia was in discussions with OpenAI about providing $250bn (£188bn) for a massive datacentre project in Ohio. Backing from Nvidia, which has an investment grade credit rating, could make it less expensive to raise funding for the project.
News of the talks knocked Nvidia’s shares on Monday; they closed 5% lower, while the cost of insuring the chip company’s debt against default using a credit default swap (CDS) rose.
“The market reaction to the Nvidia news was swift. Nvidia fell 5% and closed the session below the $200-per-share mark. More importantly, Nvidia’s five-year CDS spiked, suggesting that it may not yet be the right time to buy the dip,” said Ipek Ozkardeskaya, a senior analyst at Swissquote.
Four leading AI models discuss this article
"The sell-off is overdone relative to still-dominant HBM positioning and intact hyperscaler AI budgets, but CDS widening and China progress warrant caution before calling the bottom."
The 11.5% Kospi plunge and >10% drops in 005930.KS and 000660.KS reflect genuine near-term risks: China’s DUV mass-production breakthrough and “circular funding” fears around Nvidia-OpenAI’s $250bn Ohio datacentre talks that spiked the 5y CDS. However, the article downplays that SK Hynix still holds >50% HBM3E market share through 2025, AI capex guidance from hyperscalers remains intact, and China’s DUV tools lag EUV by multiple generations. MorningStar correctly called the move a kneejerk overreaction. Valuation at 11.6x forward P/E against 19% EPS growth still leaves room for re-rating if Q2 confirms order momentum.
If China’s self-sufficiency accelerates faster than expected and hyperscalers begin deferring capex amid ballooning balance-sheet leverage, the entire AI supply chain could face a multi-year reset far deeper than this 11% correction.
"Nvidia’s transition from a pure-play hardware manufacturer to a primary financier for its own customers introduces systemic credit risk that the market is only beginning to discount."
The market is finally pricing in the 'circular funding' risk I’ve been flagging: AI capex is currently decoupled from end-user revenue growth. When Nvidia acts as the primary lender to its own customers to sustain demand, it transforms from a hardware vendor into a highly leveraged credit facility. A 5% drop in NVDA and a spike in CDS spreads reflect a fundamental shift in risk perception—investors are no longer valuing AI stocks based on infinite growth, but on balance sheet solvency. The Chinese DUV progress is a secondary catalyst; the real danger is the exhaustion of the 'build it and they will come' investment model that has inflated these valuations.
The 'circular funding' narrative ignores that these datacenters are tangible, long-lived infrastructure assets that provide massive compute utility, which will eventually command subscription pricing power regardless of initial financing structures.
"The sell-off conflates geopolitical risk (China's chip tools), financial risk (circular funding), and valuation reset, but none alone justifies an 11.5% Kospi crash—this looks like capitulation driven by multiple fears compounding, not new fundamental deterioration."
The article conflates three distinct risks—China's DUV progress, AI capex debt spirals, and Nvidia's circular funding—into one narrative. But the evidence is mixed. CXMT's 466% IPO pop is speculative fervor, not proof of competitive threat; DUV tools are years behind EUV in capability. The real concern: if AI ROI disappoints, the $250bn Ohio project becomes a stranded asset, and Nvidia's credit rating faces pressure. However, the CDS spike on Nvidia is modest context—it spiked during the 2022 crypto crash too and recovered. SK Hynix and Samsung's 10% drops may reflect valuation reset rather than existential threat; memory chip demand from datacenters remains robust near-term.
If China's DUV capability accelerates faster than Western estimates suggest, and if AI companies' capex spending actually *does* generate outsized returns (justifying the debt), then this sell-off is a gift to long-term buyers, and the article's doom-mongering is precisely the kind of panic that creates buying opportunities.
"Near-term weakness is driven more by funding and liquidity risks than by fundamental AI demand, so a stabilizing credit backdrop could unlock a quicker rebound in semis."
The article highlights a sharp sell-off in Korea’s semiconductor names as investors fret over debt-fueled AI datacenter expansion and rising China competition (DUV tooling progress, CXMT IPO). The missing context is whether this is a liquidity/financing shock or a genuine demand slowdown. If credit conditions tighten or rates stay elevated, hyperscalers may delay capex, depressing memory/compute cycles for quarters. China’s domestic tooling advance could press margins longer-term, fueling pricing pressure on Western players. The narrative also risks treating a cyclical pause as a structural bust. In short, risk is duration: a drawdown that could persist if funding remains tight, even with solid long-run AI demand.
But the sell-off could be overdone: AI capex remains supported by secular demand, hyperscalers can refinance at favorable terms, and Nvidia/OpenAI funding chatter may actually alleviate liquidity concerns, potentially triggering a faster rebound.
"Nvidia exposure is mostly equity and pre-sold capacity, not pure circular credit risk."
Gemini's circular-funding thesis overstates Nvidia's lender role; the Ohio datacentre is co-financed by SoftBank, Microsoft equity commitments, and project-level debt. CDS spike to 68bps remains well below 2022 levels. Nobody has flagged that if HBM3E pricing holds amid China's DUV lag, SK Hynix margins could expand to 48% in 2026, accelerating de-leveraging.
"The market is mispricing the defensive moat of HBM3E packaging versus the commodity-level threat of Chinese DUV-based memory."
Gemini, your 'circular funding' narrative misses the role of sovereign wealth and institutional capital. Nvidia isn't just lending; it's orchestrating a consortium. The real risk isn't balance sheet solvency, but the 'memory wall.' If HBM3E yields improve, the bottlenecks shift from compute to interconnects. SK Hynix’s 10% drop is a mispricing of their moat in HBM packaging, which is far more defensible than the commodity DUV-based memory China is currently chasing.
"HBM3E margin expansion is hostage to China's DUV timeline, which nobody here has concrete data on—we're all guessing."
Grok's 48% HBM3E margin forecast by 2026 assumes pricing power persists despite China's DUV scaling. But that's precisely the risk: if CXMT or SMIC achieve 7nm DUV yields within 18 months (speculative, but IPO fervor suggests internal confidence), commodity memory pricing collapses faster than HBM3E adoption accelerates. The 'memory wall' pivot Gemini flagged is real, but it only matters if AI companies can afford the interconnect tax when capex returns tighten.
"7nm DUV yields within 18 months is likely overstated and would undercut the memory pricing power that supports the bullish HBM3E margins."
Challenging Claude: your scenario where 7nm DUV yields within 18 months is a big optimistic leap and would slam commodity memory pricing, which would undercut the HBM3E-margin bull case you imply. The risk isn’t just pricing power fading, but a faster-than-expected memory interconnect bottleneck and capex payback compression if AI ROI disappoints. If DUV progress accelerates, SK Hynix margins don’t rise in a vacuum; demand for memory could crater.
The panel discussed the recent sell-off in Korean semiconductor stocks, with the main concerns being China's progress in DUV tools, potential debt issues around Nvidia's AI datacenter expansion, and the risk of a slowdown in AI demand.
