Samsung and SK Hynix Edge Toward 200T KRW Combined Profit on AI Memory Boom

The Quick Take

• Samsung and SK Hynix are expected to post combined Q3 operating profit approaching 200 trillion Korean won
• AI server demand and surging memory semiconductor prices are the primary drivers of the record earnings
• Securities analysts are raising target prices for both chipmakers as the memory supercycle gains momentum

Samsung Electronics and SK Hynix are on the verge of posting a combined quarterly operating profit approaching 200 trillion Korean won for Q3 2026, driven by explosive AI server demand and a surge in memory semiconductor prices, according to financial reporting from Korean news sources. The result would represent an 'earnings surprise' for both companies as securities analysts raise their target prices, pointing to a meaningful valuation re-rating in progress. AI infrastructure buildout — led by global hyperscalers purchasing high-bandwidth memory at premium prices — is the primary driver of the extraordinary profitability.

The combined earnings milestone for Samsung and SK Hynix represents a significant consolidation of South Korea's position at the center of the global AI chip supply chain. Both companies produce DRAM and NAND flash memory that are essential components of AI server configurations, and the pricing power they have achieved reflects the structural mismatch between explosive AI demand and constrained advanced memory supply. Korean securities firms have been raising valuations across both names, with the target-price revisions suggesting the market is beginning to price in an extended supercycle rather than a cyclical peak.

The primary forward catalyst is the formal Q3 earnings release from both Samsung and SK Hynix, where divisional breakdowns will quantify the AI chip contribution and provide forward guidance on HBM memory capacity expansion. An important contextual watchpoint is the Korean won exchange rate — the currency has declined approximately 200 won in the past three months, which creates a mixed picture for Korean export earnings: strong semiconductor revenue in USD terms may be partially offset by forex headwinds when converted to KRW. The macro variable is whether AI chip demand sustains into Q4 and 2027, as any signal of hyperscaler capex moderation would trigger swift profit-taking.
