South Korea’s KOSPI surged 4.56% to a fresh all-time high of 8,457 on Wednesday, officially doubling year-to-date in 2026. Samsung Electronics and SK Hynix powered the move, the two chipmakers that already represent roughly half of the index.

The benchmark added around $220 billion in market value in a single session and roughly $900 billion in May alone.

The KOSPI is now up roughly 100% year-to-date, after Samsung Electronics jumped 6.5% and SK Hynix added 9.5% on Wednesday. The two chipmakers control around 42% of the index, lifted by AI memory chip demand.

“Everything memory related has gone straight vertical,” market commentator Heisenberg observed.

JPMorgan recently raised its KOSPI target to 9,000, with a bull case of 10,000.

Asian retail is doubling down. The 2x Leveraged SK Hynix ETF in Hong Kong has pulled in $1.3 billion year-to-date and tripled to $8 billion in assets in three months, the world’s largest single-stock leveraged ETF, the Kobeissi Letter reported.

A 2x Samsung ETF has matched those flows. Together, the two ETFs now eclipse comparable leveraged products on Tesla and Microsoft, with SK Hynix and Samsung accounting for nearly 50% of the $4.5 trillion KOSPI.

“Asian retail investors are rushing into leveraged chip stock bets like never before,” The Kobeissi Letter remarked.

Earlier, the same retail base used to anchor Korea’s Bitcoin (BTC) market. Upbit and Bithumb handle around 96% of Korean crypto volume.

But now, Korean crypto volumes have crashed roughly 80% as won liquidity has rotated into equities. The kimchi premium recently sat near negative 2.19%, signaling weak local demand for BTC.

Past KOSPI corrections triggered a reverse rotation back to Korean exchanges. On May 15, the KOSPI breached 8,000 intraday before crashing 8.4% in a single session. That reversal wiped roughly $370 billion in market value and briefly nudged Korean crypto volumes higher.

President Lee Jae-myung’s won-pegged stablecoin push and Bitcoin spot ETF pledge add a structural pull on the other side. A consortium of eight banks is preparing a regulated KRW stablecoin under the Digital Asset Basic Act. Kookmin, Shinhan, and Woori lead the group.

The motivation is concrete. Korean crypto exchanges sent roughly $40 billion overseas in Q1, with stablecoins making up half of that capital flight. A domestic won-backed token would let regulators keep more of that liquidity onshore.

With KOSPI now stretched 100% in five months on borrowed money, any unwind would land on a deep base. Korea counts nearly 10 million crypto investors, more than 30% of the population. A failed defense of 8,000 could change the tape fast. A pause in chip orders or a sharp won move sends retail back to Bitcoin and Korean altcoins.
