Cotality launches Broker Listing Exchange with KW, HomeServices

Cotality has launched Broker Listing Exchange, or Cotality BLX, with Keller Williams and HomeServices of America as the first firms to implement the system, according to an announcement on Tuesday. 

Cotality BLX is an enterprise listing management and distribution platform that gives brokerages more direct control over how listings are created, standardized and syndicated across MLSs and portals, according to the announcement.

“Cotality Broker Listing Exchange provides the stable, mission-critical foundation brokerages and affiliated agents need to navigate change with confidence,” Kevin Greene, general manager of real estate solutions at Cotality, said in a statement. “We are proud to provide the rails that keep listing data moving seamlessly and securely for the entire industry.”

The Irvine, Calif.-based property data and analytics firm, which says it supports 80% of real estate transactions in North America, said Cotality BLX is designed as a single, branded environment where brokerages can manage listing data from pre-market through closing, determine which MLSs, portals and partners receive the listing and apply brokerage and channel-specific policies and professional standards at the point of data entry. The tool is powered by Cotality’s CoreAI technology and uses Real Estate Standards Organization (RESO) standards and embedded business rules to help keep data consistent and compliant throughout the listing lifecycle.

“Our priority is making sure our agents and brokerages control their listing content from the moment it’s created — not after it’s been distributed and returned to them,” said Chris Kelly, president and CEO of HomeServices of America. “As the landscape evolves, ownership, access and flexibility around listing data will define competitive advantage.”

Chris Czarnecki, the CEO and president of Keller Williams added that reducing duplicate entry across platforms and creating a more centralized experience helps agents save time and “gain greater control over their listings while creating maximum exposure opportunities for their clients.”

“We heard clearly from agents and franchise owners that managing listings across multiple platforms creates unnecessary friction in an already fast-moving business,” Czarnecki said in a statement. 

One-to-many gateway

For brokerage leaders, Cotality BLX is positioned as a “one-to-many” gateway that allows them to set and adjust listing distribution strategies in one place. The company said this can help reduce dual-entry friction and ensure that exposure is optimized across chosen channels while preserving brokerage sovereignty over listing content.

Cotality said more than 1 million agents already use its underlying technology daily, which it argues should shorten the learning curve and support faster enterprise rollout of BLX. The platform is natively integrated with all MLSs that use Cotality’s Matrix system, creating a turnkey experience for those users. Cotality also plans to work with other MLS vendors to plug BLX into their systems and maintain a standardized on-ramp for listing data industrywide.

Cotality president and CEO Patrick Dodd framed the launch as part of a broader effort to balance MLS transparency with brokerage control.

“Cotality has always believed that a healthy industry depends on a strong, transparent MLS and the sovereignty of the brokerage,” Dodd said. “With Cotality BLX, we aren’t just giving brokers a tool to operate in today’s new marketplace; we are providing a solution that enables compliance, safeguards data and helps preserve the professional standards that our industry and consumers expect.

Cotality is partially owned by Stone Point Capital, which made a strategic investment in Keller Williams in March of 2025.
