Market reaction
Zillow Group shares tumbled by up to 20% on Wednesday after the online real-estate marketplace released a first-quarter adjusted EBITDA forecast that did not meet analyst expectations. The drop represented Zillow’s sharpest single-session fall since 2021 and prompted investors to reprice exposure to companies tied to the housing market.
Broader selloff among real-estate-linked names
The weakness in Zillow shares coincided with a wider pullback across real-estate-related stocks. Notably, both CBRE and Rocket Companies saw their shares fall roughly 10% during the trading day, reflecting spillover effects from Zillow’s disappointing outlook.
Analyst commentary on Rocket Companies
The share decline at Rocket occurred despite positive analyst notes preceding the move. Morgan Stanley highlighted that Rocket’s 8-K filing confirmed the strongest fourth-quarter gain-on-sale margin in four years, and the bank suggested that this could point to about a 10% upside to adjusted revenue estimates. Bank of America had also reiterated a Buy rating ahead of fourth-quarter results, observing that industry data and the company’s commentary indicated meaningful upside potential for both mortgage origination volumes and gain-on-sale revenue.
Integration and portfolio context
BTIG drew attention to Rocket’s recent corporate changes, noting that its merger with Mr. Cooper closed on October 1, 2025. That timing makes the fourth quarter the first full period that reflects the combined operations. BTIG also described the pro-forma servicing portfolio, which contains nearly $1.3 trillion in unpaid principal balance of mortgage servicing rights and carries an estimated fair market value of about $19 billion.
Takeaway
The immediate market response underscores how a single company’s guidance can reverberate across related sectors. Zillow’s guidance shortfall directly pressured its own stock and appears to have amplified volatility among real-estate services and mortgage-finance names, even where analysts had highlighted potential upside.
