Core Event: KOSPI Breaks 7,000 and Moves to Seventh-Largest Global Market
On May 6 2026 the KOSPI closed at 7,384.56, its first breach of the 7,000 level. Bloomberg’s tally shows Korean listed companies’ market value rose 71 % YTD to $4.59 trillion, edging past Canada’s $4.5 trillion and placing Korea seventh worldwide.
Drivers: AI Chip Demand and Semiconductor Earnings
Global AI hardware demand has pushed memory-chip makers to reallocate >90 % of advanced capacity to high-bandwidth memory, tightening supply. Samsung Electronics posted an eightfold Q1 profit rise to 57.2 trillion won, with chips accounting for 94 % of revenue, and crossed the $1 trillion market-cap mark. SK Hynix, once under $100 billion, is now near $800 billion, its shares up 10.6 % as it secures long-term supply contracts.
Market Snapshot
- KOSPI up 74-75 % YTD, 6 % on May 6.

Official Views
Eugene Asset Management’s CIO Ha Seok-Keun said the AI-led memory cycle will keep expanding Korea’s market. Kiwoom Securities’ Han Ji-young highlighted improving foreign-flow conditions after U.S. chip gains. Mirae Asset’s Seo Sang-young warned the KOSPI could reach 10,000 points if AI demand stays strong, but could fall to 4,500 if it falters. Fidelity International’s Ian Samson noted upside. Democratic Party leader Jung Cheong-rae credited market reforms for restored confidence.
Dissenting Views
Vantage Point’s CIO Nick Ferres warned that soaring valuations are “dangerous” and that a slowdown in AI funding could curb earnings. Analysts flagged the surge in margin-trading by retail “ants” as a volatility source, noting that rapid deleveraging could trigger a correction. Samsung also faces a pending union strike over bonus payouts, adding labor-relations risk.
Conflicting Data
Sources report KOSPI’s YTD gain as either 74 % or 75 %, reflecting a minor discrepancy. Bloomberg and Reuters agree on Korea’s $4.59 trillion market cap, but the timeline for sustained AI-driven demand remains unverified.
Verbatim Quotes
> “Korea’s market capitalization is likely to expand further, driven by the AI-led memory cycle, while Canada’s is more constrained given its heavy concentration in energy and financials,” — Ha Seok-Keun, CIO, Eugene Asset Management
> “After the rally of semiconductor stocks, other AI-related stocks will now have to catch up,” — Kwon Soon-kuk, office worker
> “It’s a seller’s market for AI suppliers,” — Alex Huang, chairman, Fubon Financial Holding
> “My sense is that it is getting dangerous,” — Nick Ferres, CIO, Vantage Point Asset Management
Outlook
If multi-year supply contracts hold and AI capital spending maintains its 70 % annual rise, analysts expect the KOSPI could top 10,000 points by year-end. A slowdown in AI funding or a sharp deleveraging of leveraged retail positions could pull the index toward 4,500 points. Upcoming earnings from Samsung and SK Hynix, plus any geopolitical shifts affecting oil prices, will shape market direction in the next quarter.
