According to a survey by Real Estate R114 on January 6, the market capitalization of apartments in Seoul stood at 1,832.3154 trillion won as of December 25, 2025.

Compared to December 2024 (1,624.6959 trillion won), this represents an increase of 207.6195 trillion won, or 12.8%, over the course of one year.

The surge in apartment prices, particularly in the "Hangang Belt" areas such as Gangnam and Mayongseong (Mapo, Yongsan, Seongdong), which are adjacent to the Han River, significantly boosted the overall market capitalization.

By district, Gangnam-gu (331.4293 trillion won), Songpa-gu (236.1034 trillion won), Seocho-gu (222.1736 trillion won), Yangcheon-gu (97.4448 trillion won), Gangdong-gu (86.7928 trillion won), and Seongdong-gu (82.5934 trillion won) recorded the highest market capitalizations.

The market capitalization of Seoul apartments is calculated by aggregating the market value of approximately 1.7 million units available for sale.
