Zillow Offers (Zillow Group)
The algorithmic home-buying ("iBuying") programme that Zillow Group, the most visited US property website, ran from April 2018 to November 2021. Zillow used pricing models descended from its Zestimate home-value estimate to make cash offers on houses, did light repairs and resold them within months, aiming to earn a fee and a spread and to move Zillow from selling advertising to agents to owning the transaction. In 2021 it pushed volume hard — buying 9,680 homes in the third quarter alone (company) — just as house-price growth slowed. On 2 November 2021 Zillow announced it would wind the business down, took a ~$304m inventory write-down for Q3, guided to a further $240–265m of Q4 losses on homes under contract, and cut ~25% of its staff (~2,000 people). Chief executive Rich Barton wrote that Zillow had "been unable to accurately forecast future home prices". The episode is the best-known case in this companion of a model good enough to inform consumers being trusted to commit a balance sheet. Its last legal tail was settled on 28 October 2026, when Zillow agreed to pay $212.5m to resolve a shareholder class action over its statements about the business (reported; court approval pending).
