OnTheMarket

What OnTheMarket does

OnTheMarket is a UK online residential property portal owned and operated by Agents' Mutual Limited and OnTheMarket Limited, wholly owned subsidiaries of CoStar Group (NASDAQ: CSGP) following CoStar's 2021 acquisition. Founded in 2015 and headquartered in London, the platform serves UK property buyers, renters, and investors through onthemarket.com and native mobile apps on iOS, Android, and Amazon, covering England, Scotland, Wales, and Northern Ireland. Its core product is a property search platform supporting for-sale, to-rent, new homes, commercial, student, retirement, rural, and overseas listings, augmented by a sold-price database sourced from the Land Registry and Registers of Scotland.

The platform differentiates through its "Only With Us" exclusive listings feature, where member agents advertise properties 24+ hours before they appear on Rightmove or Zoopla (averaging over 4,000 exclusive properties monthly in Jan-Aug 2024). Additional product modules include Help Me Choose, Keywords Search, Travel Time Search, Instant Online Valuation (powered by propertypriceadvice.co.uk), Property Alerts, and an Agent Directory. Commercial property listings are powered by sister CoStar platform LoopNet, and rental workflow tools are delivered through a Canopy partnership.

OnTheMarket operates a two-sided B2B2C marketplace model: the portal is free for property seekers, while revenue is generated from estate agents, letting agents, and new homes developers who pay recurring subscription/membership fees to list properties and manage their presence through the OnTheMarket Expert professional platform. The company serves a fragmented base of UK agents — ranging from enterprise brands such as Knight Frank, William H Brown, eXp UK, and Stags to mid-market and branch-level agents — and competes primarily with Rightmove and Zoopla in the UK residential portal market.

Expansion highlights5 records

Broad incumbents

• Realtor.com: US residential property portal operated by Move, Inc. (News Corp). Comparable to OnTheMarket as a property search portal monetizing real estate agent subscriptions, though it serves a different geography and competes against larger incumbents Zillow and Redfin.
• LoopNet: CoStar-owned commercial property portal that already powers OnTheMarket's commercial listings. As a sister brand within the same parent, LoopNet is a key integration partner and a comparable for commercial real estate portal economics relevant to OnTheMarket's commercial ambitions.
• Homes.com: US residential property portal operated by OnTheMarket's parent CoStar Group. While operating in a different geography, it is a sister brand within the same corporate portfolio pursuing a similar agent subscription model, making it a relevant internal comparable for strategy and product direction.
• Zillow: Largest US residential property portal. While US-focused, Zillow is the global benchmark for property portal business models, including agent subscriptions, valuation tools (Zestimate), and consumer search, providing strategic context for OnTheMarket's portal economics.

Regional players

• Idealista: Leading property portal in Spain, Portugal, and Italy. Comparable to OnTheMarket as a vertically focused property portal with subscription-based agent listings and consumer search, although it serves southern European markets.
• Immobilienscout24: Germany's largest property portal. Comparable as a residential property portal monetizing agent subscriptions with consumer-facing search and valuation features, though it operates in Germany rather than the UK.
• Property Finder: Leading property portal in the Middle East and North Africa. Comparable to OnTheMarket as a regional property portal with subscription listings, agent directories, and consumer search features, although focused on MENA markets.
• Domain Holdings: Leading Australian residential property portal. Comparable as a regional property portal business with agent subscription revenue, valuation tools, and new development listings, though it operates exclusively in Australia rather than the UK.

Direct peers

• Rightmove: UK's largest residential property portal and OnTheMarket's primary competitor. Both serve property buyers, renters, and estate agents in the UK with subscription-based listing models; Rightmove holds dominant market share while OnTheMarket positions as the #3 challenger.
• Zoopla: UK property portal operated by Zoopla Limited (owned by Silver Lake and Cox Automotive) and OnTheMarket's closest direct competitor. Both platforms monetize estate agent subscriptions, offer consumer property search, and feature valuation tools; Zoopla holds the #2 position behind Rightmove.
