Pre-Market Listings Are Reshaping How US Homebuyers Access Property

United States | September 18, 2026: The growing battle over pre-market property listings is changing how homes can reach buyers before they officially enter the broader market. As major brokerages and portals build competing early-access networks, the size of those networks could increasingly influence where buyers find homes and how sellers choose to market them.

The shift is creating a new layer of competition in the U.S. housing market, with Compass pursuing a multi-phase marketing strategy while Zillow, Realtor.com and other industry players develop broader distribution models.

Why Pre-Market Listings Are Becoming More Important

Pre-market listings allow homes to be marketed to potential buyers before they receive wider exposure through the traditional marketplace.

According to RealScout CEO and co-founder Andrew Flachner, whose views are featured in the original Industry Decoded column, the growing importance of these listings is driven by a network effect.

The basic idea is that more listings can attract more buyers, while greater buyer activity can generate more demand data and encourage additional agents and sellers to participate.

As participation grows, the network can become increasingly valuable to its members.

How the Network Effect Works in Real Estate

The emerging model can broadly be divided into three stages.

Inventory: A brokerage accumulates homes available before a broader market launch.

Distribution: Those homes are presented to buyers through websites, agent relationships and other consumer channels.

Data: Buyer searches, saves, rejections and conversations can generate information about demand.

More inventory can attract more buyers. More buyers can generate more data, while stronger buyer demand can make the network more attractive to agents and sellers.

This cycle is central to the argument made by Flachner in the column.

 

Compass Has Put Private Inventory at the Centre of Its Strategy

Compass has increasingly incorporated private and pre-market inventory into its three-phase marketing strategy.

The company's acquisition of Anywhere has also expanded its agent and listing footprint, giving Compass a larger network through which to implement its approach.

The strategy creates a potential competitive advantage if buyers and sellers begin valuing access to inventory that is not immediately available through the wider market.

However, the extent of that advantage depends on how much inventory, buyer demand and agent participation the network can continue to attract.

Why Zillow and Other Portals Are Responding

The growing use of pre-market listings has also pushed competitors to develop alternative models.

Redfin now distributes Compass Coming Soon inventory, while Zillow introduced Preview, allowing participating brokerages to distribute pre-market properties through a broader portal network.

Zillow and Realtor.com have also recently expanded their cooperation, with Zillow Preview listings becoming visible on Realtor.com.

For buyers, this creates an important distinction between a closed brokerage network and an open distribution network.

A closed system concentrates inventory within one brokerage ecosystem, while an open model can potentially combine listings from multiple participating brokerages.

The Scale Problem for Smaller Brokerages

One of the biggest challenges for smaller brokerages is scale.

A brokerage with limited market share may not have enough pre-market inventory or consumer traffic to create the same network effect as a much larger organisation.

That creates two potential paths: build an individual private network or participate in a broader platform that aggregates inventory from multiple brokerages.

The second approach could give smaller firms access to a larger pool of potential buyers without having to build the entire consumer network themselves.

 

What This Means for Homebuyers and Sellers

For homebuyers, the growing pre-market ecosystem could provide earlier visibility into properties, but it may also make the search process more fragmented if different brokerages control different inventories.

For sellers, the choice could increasingly involve a trade-off between broad exposure and early access to targeted buyers.

For agents, access to inventory and the ability to connect sellers with buyers could become an increasingly important part of brokerage competition.

The practical question for consumers will be whether a property receives broader exposure quickly or is first marketed through a specific pre-market network.

Open Networks vs Private Property Access

The industry debate is ultimately about how much property inventory should be visible to the broader market.

Supporters of open distribution argue that wider visibility gives more buyers an opportunity to discover homes and gives sellers access to a larger audience.

Private-network strategies can instead emphasise controlled marketing and early access through specific brokerage relationships.

Neither model guarantees a particular outcome for an individual seller or buyer. The impact will depend on the property's location, demand, pricing, agent strategy and the reach of the distribution network.

What Happens Next

The competition over pre-market inventory is likely to remain an important issue for U.S. residential real estate as brokerages and portals expand their respective networks.

The key factor to watch will be scale — how much inventory each network can attract, how many buyers it reaches and how many agents and sellers participate.

For homebuyers, that could make monitoring multiple property platforms increasingly important. For sellers and agents, the choice of where and when to expose a property could become a more significant part of the overall marketing strategy.
