Samsung, SK Hynix Forecast Record Q3 Profits on AI Memory Boom; KRW a Risk

The Quick Take

• Samsung Electronics and SK Hynix both expected to post record Q3 operating profits as AI-driven memory demand surges
• Samsung Q3 operating profit forecast above 100 trillion won, topping Q2's record of 89.5 trillion won
• SK Hynix Q3 operating profit estimated above 70 trillion won, exceeding its own Q2 record of 60.5 trillion won
• Won-dollar exchange rate decline flagged as a key risk that could partially offset both companies' earnings gains

Samsung Electronics and SK Hynix are both on track for record-breaking third quarter operating profits, according to industry consensus estimates, driven by the continued expansion of AI memory demand from hyperscale cloud operators and AI infrastructure buildout globally. Samsung's Q3 operating profit is projected to exceed 100 trillion won, surpassing its prior record of 89.5 trillion won set in Q2, while SK Hynix is expected to deliver approximately 70 trillion won in Q3, above its Q2 record of 60.5 trillion won. The AI-driven memory semiconductor supercycle is now in its third consecutive quarter of record performance for both companies, reflecting sustained demand for high-bandwidth memory products used in AI accelerator systems.

The broader AI memory ecosystem — including DRAM suppliers, HBM stack assemblers, and substrate manufacturers — stands to benefit from the sustained earnings strength at Samsung and SK Hynix, as their record results validate demand assumptions that underpin capital expenditure plans across the semiconductor supply chain. A parallel development — an antitrust lawsuit filed against major AI companies including OpenAI, Anthropic, Google, and SpaceXAI for allegedly colluding to slow AI development — introduces a regulatory risk variable that, if successful, could constrain the pace of AI infrastructure investment and consequently moderate memory demand growth beyond the current record cycle. The AI electricity demand debate in Korea also signals an infrastructure cost overhang.

The primary forward signal for Samsung and SK Hynix is the price trajectory of high-bandwidth memory and DDR5 server DRAM in Q4, which will determine whether the record earnings cycle extends into 2027. The key risk variable explicitly identified by analysts is the won-dollar exchange rate: a stronger won reduces the Korean-won value of USD-denominated semiconductor revenues, partially offsetting volume gains. Any deterioration in hyperscaler AI capex guidance — from Microsoft, Amazon, Google, or Meta — in upcoming earnings calls would be the most consequential leading indicator of whether AI memory demand sustains the current record trajectory through year-end.
