Zillow Group’s Class C shares (Z) traded lower as investors digested a fresh downgrade in Zillow’s own housing outlook. Zillow Research’s April 2026 forecast now expects typical U.S. home values (ZHVI) to rise about 0.3% by December 2026 and projects weaker existing-home sales momentum than previously modeled, reflecting a more cautious view of transaction activity and price growth.

In the April 2026 forecast, Zillow projected: (1) typical home value growth of +0.3% by December 2026, described as a downward revision from the prior month; (2) existing-home sales of 3.73 million in 2026 on Zillow’s sales-count nowcast (+0.5% year over year); and (3) an increase in NAR-measured existing-home sales to 4.13 million (+1.6% year over year). Zillow linked the softer expectations to stronger inventory growth relative to sales and upward revisions to mortgage-rate expectations driven by persistent inflation concerns.

Zillow’s core marketplace economics are closely tied to housing liquidity: more listings, tours, and closed transactions typically translate into greater lead flow and advertising demand from agents and related housing-services partners. A forecast that points to flatter home-value appreciation and slower sales growth can pressure sentiment because it implies a less supportive backdrop for near-term monetization, especially if borrowing costs stay elevated and buyers remain rate-sensitive.

Traders will likely focus on upcoming housing data releases and rate-sensitive indicators that can quickly reset expectations for spring and summer activity. Any meaningful change in mortgage-rate trends, inventory growth, or consumer confidence could influence forward views on transaction volume—and, by extension, Zillow’s near-term revenue outlook.
