On February 6, 2025, we entered into a partnership with Redfin Corporation (“Redfin”), making Zillow the exclusive provider of multifamily (properties with 25 or more units) rental listings on Redfin and its sites, including Rent.com and ApartmentGuide.com (together, “Redfin Rental Network”). Pursuant to this rentals partnership, Zillow made a $100 million payment to Redfin that is included in customer relationships in the table above and is being amortized over the estimated useful life of nine years. Zillow also pays Redfin for leads generated through the Redfin Rental Network for an initial period of five years with two optional two-year extensions, subject to the terms of the underlying agreements.

Amortization expense recorded for intangible assets was $22 million and $20 million for the three months ended September 30, 2025 and 2024, respectively, and $64 million and $58 million for the nine months ended September 30, 2025 and 2024, respectively. We did not record any impairment costs related to intangible assets for the three or nine months ended September 30, 2025 or 2024.
