US Online Real Estate Platform Stocks Surge by 780 Billion Won in One Day

Shares of Zillow Group Inc. (NASDAQ: Z) surged 6.40% on the Nasdaq, closing at $45.07. In a single day, its market capitalization rose by about $580 million (roughly KRW 780 billion), bringing its total value to approximately $8.46 billion (around KRW 11.4 trillion). Trading volume reached 4.43 million shares.

On the 10th of last month, Zillow reported fourth-quarter 2025 revenue of $654 million, an 18% year-over-year increase, though its adjusted earnings per share of $0.39 slightly missed analysts’ estimates. Then, on the 5th of this month, the company approved an additional $1.25 billion (about KRW 1.7 trillion) share buyback, raising the total authorization to $1.3 billion (around KRW 1.8 trillion). Zillow also disclosed it has repurchased $626 million (approximately KRW 840 billion) of its own stock so far this year.

Founded in 2006 by former Microsoft executive Rich Barton and colleagues, Zillow is one of the United States’ leading online real-estate marketplaces, offering information on home sales, rentals and mortgage financing. Its main revenue drivers are advertising for real-estate agents, lead-generation services and fees from rental and mortgage solutions. The company has since exited its direct home-buying business to focus on its platform and fintech offerings.
