0:00The AI boom is usually told as a Silicon Valley story. But some of the biggest winners

0:05are thousands of miles away – in South Korea. This year, Samsung Electronics and SK Hynix have reaped

0:12the benefits of America’s AI spending surge. South Korea has two of the three hottest companies,

0:18dare I say, in the world right now as it relates to the AI trade. From January till May,

0:23South Korea's KOSPI surged almost doubled at one point, but since it's been a bit volatile.

0:30But in the grand scheme of things, the KOSPI has been one of the best performing markets. But the

0:35surprise is where some of those stock market gains are showing up next: property. In South Korea,

0:42apartments — especially in Seoul — are more than just places to live. They are one of the

0:47country’s most trusted stores of wealth. As of end-March 2025, real assets accounted for

0:5275.8% of Korean household assets, compared with 24.2% for financial assets. For high-end homes

1:00above 1.5 billion won (or about 1 million U.S. dollars), the share of purchase funds coming

1:06from stock and bond sales reportedly reached 13.2% in April 2026, after staying below 5% in

1:13previous years. Housing market has provided very stable return for very long time. Before

1:20this massive rally, housing market return was around 4% per year, but the stock market is just

1:26like 1% with really you know the high volatility. And that created a lot of the social problem as

1:34well. That creates a chain reaction: America’s AI spending helps create chip wealth in Korea.

1:40Some of that wealth flows into property. And in an already expensive housing market, that can add

1:45pressure on people who do not yet own assets. So, Korea’s AI windfall is becoming a two-sided story:

1:52corporate profits and market gains on one side – and a deepening asset divide on the other.

2:04South Korea’s place in the AI trade starts with memory. Nvidia’s processors may get most of the attention.

2:11But AI systems also depend on high-bandwidth memory, or HBM — fast, stacked memory that helps

2:17those processors move massive amounts of data. And right now, South Korean companies are among the

2:23most important suppliers. Over the last few years, Hynix has dominated the HBM market. They had

2:29around 60% market share, with the rivals Samsung and Micron, both holding around 20%. So clear

2:35dominance by SK Hynix. This was partly because Samsung suffered from yield issues, so issues in

2:42manufacturing the chips and Micron were focused on a completely different technology altogether,

2:47so they really started on a back foot. Now with HBM4, that dynamic is beginning to change.

2:54Samsung Electronics and SK Hynix now account for more than half of the KOSPI’s market value. So, when those

2:59two stocks rise, they can lift the whole index with them. This shows up in share prices — and

3:05in workers’ paychecks. SK Hynix promised their workers last year that they would pay 10% of their

3:10operating profit as bonuses, and that equates to around 700 million won, or if you round it up,

3:16half a million dollars. That's 15 times more than the average salary that an average South Korean

3:22took home. Samsung workers, specifically those in the memory chip division, they are expected

3:29to take home around 600 million won in bonuses. So that's a little less than SK Hynix, but still

3:37massively greater than what average Koreans make in one year. But the key question isn’t just who

3:43benefits from the AI trade. It’s where that new wealth goes next. For many Korean households,

3:48stock-market gains are a pathway to property. Owning a home is sort of the Korean dream for

3:54all Koreans. I think in Korea is a reflection of what people consider as their safety net,

4:01an investment destination as well as a symbol of success. Their ultimate goal in Korea is

4:07to buy housing, and the stock market is kind of their stepping stone towards the housing market.

4:14The Bank of Korea says stock-market gains are far less likely to turn into spending in Korea. There,

4:20just 1.3% of stock-market capital gains translate into consumption, compared with roughly 3 to 4%

4:26in the U.S. and Europe. For households that do not own their homes, the pattern is even

4:31clearer. About 70% of stock gains are estimated to flow into real estate. And that appears to be

4:38showing up in the market. From January to April 2026, homebuyers used about 3.7 trillion won,

4:44or roughly 2.4 billion dollars, from stocks and bond sales to fund purchases. Nearly two-thirds of

4:50those proceeds went into homes in Seoul, with the largest concentration in three affluent southern

4:55districts: Gangnam, Songpa and Seocho. Prices in Seoul are rising. Recent data from Deutsche Bank

5:02show that Seoul is the third most expensive city to buy a home after Hong Kong and Zurich. So that

5:09really just goes on to show how expensive it is to buy homes in Korea. That creates a policy problem.

5:16Korea has tried to steer household wealth away from overheated housing and into financial

5:21markets. The stock-market rally shows that part of the strategy has worked. But some of those

5:26gains appear to be making a round trip — back into property. That creates the paradox at the heart

5:32of Korea’s AI rally: the wealth is real, but its benefits are not landing evenly. The Bank of Korea

5:38calls this a form of “complex polarization”: asset inequality is deepening because of real estate,

5:44while income inequality is starting to widen again as growth concentrates in a few high-paying

5:49industries. The divide starts with ownership. The Bank of Korea tracks the wealth gap between

5:55households that own real estate and those that do not. By 2025, that gap was close to 470 million

6:02won or about 315 thousand USD. That’s more than nine times average household income. For owners,

6:09rising property prices can add to wealth. But for non-owners, those same price gains make

6:14the starting line harder to reach. This second chart compares median home prices with the net

6:20assets of households that don’t own a home. The higher the bar, the higher it is to buy in. The

6:26barrier has come down from its 2022 peak, but it remains far above where it was a decade ago. And

6:32for young non-homeowners, it’s rising again. It's something that the former Bank of Korea governor

6:39mentioned many, many times that he's seeing this K-shaped economy that's split between the tech

6:45sector and the non-tech sector, and we're seeing it spill over into sort of our more

6:50day-to-day lives. That brings Korea to another risk. The danger is not that one stock market

6:56sell off would immediately crash home prices. It’s that the same wealth channel pushing stock gains

7:01into housing depends on confidence. When chip stocks rise, investors have gains to cash out,

7:07employees expect bigger bonuses, and buyers have more money for down payments. But if those gains

7:13fade, some of that confidence can fade too. It's really long-term potential threat to the economy,

7:20not just the economy but society as a whole. Recently the government is pushing for like the

7:26mega project. So basically you know the broadening the gains from the chip sectors to other sectors,

7:33and they want to cultivate new growth engine for future growth. If we see the chip cycles declining

7:41very sharply, it can have like a massive negative impact on growth inflation and the household

7:48wealth. I think the Korean government and companies are trying to reinvest the money that

7:53they have earned into areas that that they think will be the next jackpot, and I think physical AI

7:59is one area, robotics is another, which is why we saw Jensen Huang come to Korea and sign

8:05all those agreements. So, if there is a slowdown or a downturn, Korea will inevitably be exposed,

8:12but for now, until 2028, chip demand looks to be there, and so it's something we'll have to see.
