South Korea’s booming stock market is attracting millions of first-time investors, marking a significant shift in a country where real estate has traditionally been the preferred avenue for building wealth.
The surge in market participation comes amid a historic rally that has transformed South Korea into one of the world’s best-performing stock markets, driven largely by strong demand for artificial intelligence-related technologies and sweeping market reforms.
Among the new investors is Kim Ha-young, an office worker in Seoul who entered the stock market for the first time after receiving extra funds following a housing deposit payment.
With little knowledge of investing, Kim purchased shares in major technology companies Samsung Electronics and SK Hynix, betting on familiar household names. As demand for AI-related memory chips surged, the value of her investments more than doubled within months.
What began as a small experiment soon became part of a broader trend reshaping South Korea’s investment landscape.
Millions Join the Market
According to financial industry data, the number of South Koreans owning stocks has risen dramatically over recent years, growing from approximately six million in 2019 to more than 14.5 million by the end of 2025.
The figure is believed to have increased further as the benchmark Kospi index continued its record-breaking rise during the first half of 2026.
The number of active trading accounts has also expanded sharply, reflecting growing enthusiasm among retail investors seeking alternatives to traditional savings and property investments.
Reforms Help Change Investor Sentiment
For decades, South Korea’s stock market struggled with what analysts referred to as the “Korea discount” — a term describing the relatively low valuation of Korean companies compared with global competitors.
Despite producing global brands such as Samsung and Hyundai, investors often criticised Korean corporations for weak governance structures and limited returns for minority shareholders.
The administration of President Lee Jae-myung has introduced reforms aimed at improving transparency and strengthening shareholder rights.
Among the measures introduced are changes that give minority shareholders greater influence in corporate board elections and increased protections for retail investors.
The government hopes these reforms will encourage more citizens to invest in productive businesses rather than relying heavily on property ownership as a primary store of wealth.
AI Boom Drives Market Rally
Much of the market’s recent growth has been fuelled by soaring global demand for artificial intelligence infrastructure.
South Korea’s leading semiconductor manufacturers, Samsung Electronics and SK Hynix, have reported record profits as technology companies worldwide race to secure advanced memory chips required for AI applications.
The strong performance of these companies has helped lift the broader market and attract new investors eager to benefit from the technology boom.
Many younger professionals view stock investing as an increasingly attractive option amid concerns about housing affordability and limited opportunities for wealth creation through traditional means.
Risks Remain Despite Strong Gains
While investor optimism remains high, analysts caution that the rally has also been accompanied by significant volatility.
Recent sharp declines in the Kospi index have highlighted concerns about the sustainability of the market’s rapid growth, particularly if global technology companies reduce spending on artificial intelligence infrastructure.
Experts note that much of the rally has been concentrated in a small number of technology firms, leaving many profitable companies in other sectors largely overlooked.
Nevertheless, market observers remain cautiously optimistic about the long-term outlook, citing continued reforms and the potential for broader participation across industries.
For investors like Kim Ha-young, the experience has reinforced the importance of patience and long-term planning.
Rather than chasing short-term gains, she now hopes her investments will help fund future goals such as home ownership and retirement, reflecting a growing shift in how many South Koreans view wealth creation in a changing economy.
