Briefing
- SK Hynix posted a 13-fold rise in second-quarter net profit, confirming that AI-driven memory demand has not softened entering the second half of 2026.
- The South Korean chipmaker, the world's second-largest memory producer, said it won multiyear supply contracts with approximately 10 customers.
- The result extends what the Wall Street Journal described as a streak of record quarterly prints, suggesting pricing power in high-bandwidth memory has been sustained rather than peaking.
- Investors will watch whether rival Samsung Electronics can close the technology gap in HBM, and whether contract terms from the newly announced deals anchor pricing visibility into 2027.
Analysis
- SK Hynix's 13-fold profit jump and multiyear supply contracts with roughly 10 customers directly contradicts the demand-destruction narrative embedded in the Kospi's 10.8% sell-off from July 28, creating a sharp re-rating catalyst for HBM-exposed names. Multiyear contract terms anchor pricing visibility into 2027, compressing the bear case that HBM pricing had peaked. The divergence between the sell-off and the fundamental print is widest for SK Hynix's US-listed shares, which had already dropped below their $149 IPO offer price.
- Samsung's inability to close the HBM technology gap with SK Hynix becomes the critical swing factor for memory sector pricing into 2027. SK Hynix's streak of record quarters and new multiyear contracts suggest it is capturing a disproportionate share of AI memory wallet, structurally pressuring Samsung's blended memory ASPs. If Samsung cannot qualify HBM3E at scale for major hyperscalers within the next two quarters, its memory segment margin recovery thesis deteriorates meaningfully.
- CXMT's 471% IPO debut and SK Hynix's record profits create simultaneous but opposing pressures on Micron: the SK Hynix result validates AI HBM demand as durable, supporting Micron's own HBM ramp thesis, while CXMT's scale signals a credible future competitor for Chinese hyperscaler volumes currently inaccessible to US suppliers. Micron's AI memory premium is therefore defensible in near-term pricing but faces a structural ceiling as CXMT narrows the gap and Chinese customers diversify sourcing.
Historical Context
- 2024
SK Hynix was first to volume-ship HBM3E to Nvidia, establishing a technology and customer lead over Samsung that translated directly into pricing power and margin advantage. That lead is the foundation of the current multiyear contract momentum and the benchmark against which Samsung's catch-up attempts are being measured.
- 2021-2022
The prior memory upcycle saw SK Hynix and Samsung post record profits on DRAM demand, followed by a sharp 2022-2023 downcycle as inventory built and pricing collapsed. The current HBM cycle differs structurally in that multiyear supply contracts, absent in commodity DRAM, reduce the volatility of the demand signal and slow the inventory accumulation that triggered the prior correction.
- 2016
Samsung's dominance in 3D NAND was disrupted when competitors including SK Hynix and Micron achieved cost parity faster than Samsung anticipated, compressing its technology premium within roughly six quarters. The HBM gap Samsung faces today carries a similar dynamic: an early technology deficit that erodes pricing and contract share if not closed rapidly.

South Korea's Kospi closes 10.8% lower as AI chip sell-off sweeps Asia
The Kospi's 10.8% single-session collapse on July 28, driven by AI chip demand doubts and Chinese competition fears, saw SK Hynix fall more than 13% and its US-listed shares drop below the $149 IPO offer price. The Q2 earnings print directly refutes the demand-side rationale for that sell-off.
CXMT surges 471% on market debut in China's largest IPO since 2010
CXMT's 471% IPO debut on July 27 crystallized Chinese domestic investor conviction around AI memory at an $85 billion market cap, establishing a rival benchmark to SK Hynix's HBM franchise precisely as SK Hynix is locking in multiyear supply contracts that assume continued pricing power.
Intel posts fastest revenue growth in 15 years on AI data centre demand
Intel's fastest revenue growth in 15 years on AI data centre demand, combined with SK Hynix's 13-fold profit jump, establishes a consistent cross-company signal that AI infrastructure capex is durable and broadening rather than peaking, directly challenging the IBM-driven narrative that AI spending is cannibalizing enterprise budgets without generating sustainable revenue.
