Will Zillow's Rentals revenue exceed $850M in FY2026?

Management guides ~30% Rentals growth for FY2026, which implies ~$819M. The $850M threshold requires ~35% growth — about 5pp above guidance. Rentals has a 32% CAGR since 2022 and grew 39% in FY2025, suggesting management may be guiding conservatively. Multifamily property count growing 44% provides a strong leading indicator. Wallet share expansion (~10% per property) adds to the growth flywheel. However, 39% to 35% represents deceleration, which management is implicitly guiding for. The Redfin syndication agreement adds a new growth vector. I lean slightly above 50%.

The bull case relies on Rentals exceeding guidance by ~4%, which is plausible given the track record of beating expectations. However, the 39% growth in FY2025 was driven by 58% multifamily revenue growth and 44% property count growth — these are high growth rates that are difficult to sustain. As the base grows ($630M is substantial), each percentage point of growth requires more absolute dollars. The Redfin syndication adds demand but also cost. I am near-even on this, slightly below 50% because $850M is a specific high bar.

63% rental listing share and growing creates pricing power — ARPU expansion can drive revenue growth even if property count growth slows. The 10% wallet share expansion observed in FY2025 (58% revenue growth on 44% property growth) suggests property managers are upgrading to premium packages. If ARPU expansion continues at a similar pace, even 25% property count growth with 10% ARPU uplift yields ~37.5% revenue growth — above the $850M threshold. The key risk is whether multifamily construction boom leads to vacancy increases that reduce advertising budgets.

Management guided 30% growth, which gets to $819M. Beating to $850M requires 35%, which is 500bps above guide. While Rentals has a history of exceeding expectations, the deceleration from 39% to 30% guided growth is meaningful — management is signaling organic deceleration. The $850M bar is specific enough that it depends on the magnitude of beat versus guidance, not just the direction. I put it slightly below 50% given the gap between guidance and threshold.

This is genuinely near coin-flip. The positive signals: 32% CAGR historically, consistent outperformance, 63% listing share creating pricing power, ARPU expansion trend, Redfin syndication adding demand. The negative signals: management guided below the threshold (30% vs 35% needed), multifamily construction boom could moderate advertising demand, base effect makes each growth point harder. The beat magnitude required (~4%) is within historical beat patterns but not guaranteed.

I weight management guidance as a strong prior. When management says 30%, they have visibility into the Q1 pipeline and full-year trajectory. Beating to 35% would require either a revenue acceleration they don't yet see, or systematic conservative bias in Rentals guidance. The latter is possible (Rentals has beaten consistently) but the magnitude of beat needed ($31M above guided midpoint) is meaningful. Slight lean toward NO.

30% guide implies $819M. Need 35% for $850M. Rentals has beaten expectations historically (39% vs unstated prior expectations). ARPU expansion and listing share dominance favor upside. Coin flip.

Management guides 30%, need 35%. The 5pp gap is meaningful. Base effect makes growth harder. While track record supports potential beat, the specific $850M threshold sets a high bar. Slightly below even odds.

63% listing share and wallet share expansion suggest pricing power will boost revenue beyond pure property growth. Redfin syndication adds incremental demand. Historical track record of beating expectations. Slight lean toward YES.
