Open Real Estate: The Brokerage and Franchisors are Bringing UpstreamRE Concept Back

On Monday, AGNT Inc. (eXp Realty and NextHome), HomeServices of America, Keller Williams Realty and Real REMAX Group announced Open Real Estate, a broker-owned national listing data-sharing initiative targeted for Q1 2027. If the pitch sounds familiar, it should. The industry has heard a version of it before, under a different name: UpstreamRE. The goal of this initiative along with BLX, Ocusell and historically, UpstreamRE, is the same – to better orchestrate brokerage level listing management. Regional firms Brown Harris Stevens and Lamacchia, Windermere, and Samson Properties have also joined.

The industry is in a better position now than ever to accomplish this. Today, about 70% of MLS listing input is standardized thanks to MLS cooperation in RESO and the update API standard.

Why do brokers want this? The potential to curate a listing in the broker’s back office, order photography, order drone footage, create floor plans, order pre-inspections, order sign service, and prep the listing for the MLS then push the listing live in the MLS is closer to reality. The headline of the Open Real Estate announcement reinforces that brokers are interested in adoption of the RESO standard for MLS update. Some MLSs have offered this service for decades and about 30 offer the service to brokers today.

The friction of rolling out this system will remain with the MLS. If the MLS does not want to license the listing add/edit schema to their brokers and adopt the RESO MLS listing update standard, the dream of going back to the days of brokerage initiated MLS listing submission is not possible.

A decade ago, Patterson-Schwartz, Ebby, and Long and Foster were the last brokers to push listings directly from their brokerage to the MLS system via electronic submission. Today, Howard Hanna, BHGRE Metro Brokers, and a host of others via the Ocusell List+ program. MLSs have supported the standard too – FMLS, Georgia MLS, BrightMLS, MLSNOW and about 30 others.

Brokers are passionate about solving this important broker problem. Brokers must also respect and understand the threat these solutions may pose to MLSs. In contracting with MLSs during the pilot, UpstreamRE agreed to the terms of the MLS that they would not create an MLS system. UpstreamRE was one broker to many MLSs with no sharing among brokers using the system. OpenRE said something different – all participants having access to each other’s listings before MLS entry as long as the listing is not publicly advertised.

UpstreamRE was a concept created by The Realty Alliance mastermind group and embraced by other brokers and NAR. It was not very well embraced by more than a handful of MLSs. Coupled with technology challenges, the 2014 initiative never realized its vision. Participating large brokers in this new flurry of announcements are hopeful that digital listing contribution to the MLS will be a supported service of every MLS.

The Open Real Estate, Ocusell, BLX and historically, the UpstreamRE Objective: Address the need for pre-mls listing management

For more than a decade, the need of listing management and curation before submission into the MLS has been a stated brokerage need. The larger the brokerage, the larger the need. In 2015, UpstreamRE promised brokers a single point of entry for listing data, with the broker controlling distribution to MLSs, portals and vendors. “Today, real estate practitioners end up entering the same data over and over and over again into different systems,” UpstreamRE boardmember Craig Cheatham said at the time. “Upstream is the broker’s data management platform, and the MLS continues to serve its vital role with its original, core functions.” If you want to see his current remarks – see his Linkedin Post here.

Now read Open Real Estate’s launch materials. Listings are entered once using a few standardized fields, then shared with participating brokerages and syndicated to local MLSs, home search sites and other platforms. The platform “is designed to work alongside MLSs, which play an essential role in establishing local listing rules.” The two propositions read nearly the same. Standardized fields are the problem. MLS systems do not have native field standards, each is different.

The founding DNA overlaps too. Keller Williams, HomeServices of America and REMAX all backed UpstreamRE. All three are co-founders of Open Real Estate, joined by AGNT. The Realty Alliance, LeadingRE, and Realogy were also UpstreamRE backers. Compass was invited to join Open Real Estate as a founding member and is not one today. Compass CEO Robert Reffkin publicly congratulated OpenRE in a social media post, so we can assume that he supports the process of brokers submitting listings to the MLS electronically. Howard Hanna, operating in 19 states, has already launched their version of OpenRE.

What happened to UpstreamRE?

Upstream’s original technology vendor was a subsidiary of the National Association of Realtors. After two years of delays driven mostly by MLS friction, the platform launched in May 2018 and was defective. NAR had spent $13 million of member dues on the project before cutting ties in December 2018. This was in addition to seven or eight figures contributed directly by UpstreamRE brokers. The cost of this solution is material given the coordination with every MLS in America, and the support by NAR provided Realtor affiliated MLSs assurances that this was not a move toward a national MLS.

An MLS vendor took over as the developer of UpstreamRE in early 2019. From 2021, Upstream rolled out narrow modules in select MLS markets–photo management, rosters and distribution–but never the full functionality. The timeline is important here – launched concept in 2014 and somewhat functional in 2019-21.

What is structurally different this time?

No trade organization, no in-house build

OpenRE is a pure brokerage and franchise consortium: no trade-organization partner, and the founders plan to buy the technology rather than build it. They say they are collecting proposals from national technology companies, expect to select one in early 2027, and are using third-party engineers. “We want to make sure this is durable and separate from all of us,” AGNT CEO Leo Pareja said on Monday’s BAM broadcast. Membership is free and open to any licensed residential brokerage or franchise and their agents. They expect launch in Q1, which is achievable given that there are production grade products in the market today.

How will it be paid for?

OpenRE plans to license the aggregated database and share proceeds with participating brokers per listing, equally, regardless of brokerage size. “Not only do we want to democratize the data, we want to democratize the monetization,” Pareja said. Revenue sharing of this kind was not part of the original UpstreamRE pitch, and how the data will actually be monetized is still undefined by OpenRE It is not clear at this point how the original build-out will be paid for, as projects of this nature generally accrue significant expenses before achieving the kind of scale that could produce meaningful revenue from data licensing. This monetization effort may compete or collaborate with MLS-supported data monetization programs like Partner InfoNet and REdistribute.

Concrete rules

OpenRE has one hard rule: members must submit a listing to the database within one business day of signing the listing agreement. At input, the broker chooses visibility: share with participants only, or syndicate widely to MLSs, portals and other sites. Local rule-making stays with local MLSs. UpstreamRE was agnostic to what brokers did or didn’t do with the data they entered into the system. OpenRE’s primary reason for existence is to enforce one, non-negotiable rule – clear cooperation. It is unclear how/if the group will address Coming Soon listings.

The context has changed too

UpstreamRE was framed as an efficiency play: stop duplicate entry, give brokers control of their data, and provide an opportunity to curate a property listing to prepare it for MLS submission, in addition to eventually becoming a near-universal platform to store and distribute all brokerage data, not just listing information. This is important. Roster management has not been discussed in OpenRE, but it was as important to UpstreamRE as listings themselves.

OpenRE arrives during the fight over private listings, as Compass battles MLSs and Zillow in court over rules that limit how brokerages can market listings before sharing them broadly, and its founders frame it in those terms: their open letter is titled “Housing Markets Must Remain Open To All.” Zillow created its own private listing network.

The visibility toggle around who can access the listings is the most interesting line in the announcement. A broker can submit a listing and keep it visible only to OpenRE participants. That sits awkwardly with the “open” branding and looks like a concession to the private-listing flexibility Compass argues for and more than have of all MLSs support today. Compass, for its part, congratulated the founders and said it looks forward to “helping build the next chapter of listing services.”

This time around, there are several products to choose from

Contrary to the UpstreamRE era, there is now a market for listing add/edit outside the traditional MLS interface. Commercial vendors and MLS-developed tools have separated listing creation and management from the system used to search and share listings. That is a meaningful difference from the environment in which UpstreamRE was conceived.

Ocusell

Ocusell is already serving brokers and MLSs across 30 MLS markets. Its listing workflow supports a complete listing entry, validation against MLS rules and distribution to multiple MLSs from one interface. Howard Hanna is a prominent customer: its HannaList initiative is powered by Ocusell, and Howard Hanna CEO Hoby Hanna describes the relationship as supporting a repeatable operating model across MLS markets. Ocusell is live, not simply a proposed solution. Born originally to enable dual listing input between neighboring MLSs, Ocusell has been a favorite for MLSs saying it will deliver listings to all the broker’s MLSs at the same time as (or before) those listings go anywhere else. This technology has been built as a complement to MLSs, addressing a core need of overlapping market disorder and has engineered the solution to seamlessly integrate with MLS systems, allowing participating MLSs to drive the execution on behalf of their brokers. This system has been live for 4 years and has already addressed several MLS and broker pain points.

MLS-developed listing management

MLSs have also developed listing-management tools separate from the traditional MLS front end, with Bright MLS serving as a prime example. In September 2025, Bright and Ocusell announced a strategic joint venture to co-develop and license listing creation and management solutions for brokers, agents, and MLSs. The partnership incorporates Ocusell’s multi-MLS listing technology (including List™ and List Plus™) into Bright Listing Manager which is part of the Bright Solutions SaaS product suite. Rather than dividing broker technology from MLS technology, the joint venture bridges both by establishing a unified “one-to-many” ingestion engine.

There is deep history behind this approach. In January 2014, MRIS (which later merged to form Bright MLS) rolled out its Keystone listing-input system nationwide. MRIS developed, owned, and operated Keystone to provide tools for maintaining listings and scheduling their submission or edits into the MLS. At the time, MRIS was one of the few MLSs building and managing its own listing-input layer, a pioneering operational model that predated industry efforts like Upstream.

REcore has an add/edit solution available to MLSs that was developed in partnership with Northstar MLS and California Regional MLS.

Cotality BLX

In May 2026, Cotality announced BLX, the Broker Listing Exchange, with HomeServices of America and Keller Williams as launch partners. Similar to Open Real Estate, the announcement for BLX explained the system is designed for brokerage-controlled listing entry and management before distribution to MLSs and portals, with native integrations into Cotality’s Matrix platform and other MLS platforms. Cotality knows listing add/edit very well, and serves half of the real estate industry today in this capacity along with distribution though Trestle and data protection though Trestle Defender. Cotality recently released Trestle MCP to support AI connectivity. The latter was not mentioned at all in the OpenRE conversation, but you must expect that AI connectivity will play a major role.

My understanding is that the BLX payload to the MLS covers about 50% of the listing input required by most MLSs. So the listing must be completed, finalized, and compliance checked inside the MLS. This gives the brokers the basic payload they need, but expands the listing inside the MLS for completing the listing, which partially defeats the single point of entry/listing management.

Zillow’s Bridge Interactive

Zillow also has listing add/edit technology through Bridge Interactive, acquired in 2016. Bridge continues to market Bridge Listing Input as a data syndication platform and secondarily, as a single-point-of-entry tool for MLS members. Its existence belongs in this discussion, even though the public materials reviewed for this article do not establish its current adoption at scale.

One national operating system, many local rulebooks

The distinction is between a national brand or franchise network and a nationally operated brokerage seeking one operating system across its business. The newer nationally operated brokerage model and significant brokerage consolidations, brings the question into focus: can a firm run a consistent listing workflow across many local MLS environments? That is a different operating challenge from putting independently run brokerages under a shared brand. It is not a claim that multistate brokerage operations were absent when Upstream was conceived.

National brokerage operations put this friction in sharper perspective. RESO counted 484 U.S. MLS systems as of August 2026, a useful measure of the fragmented environment, though not a count of distinct geographic markets. More than 200 MLSs have yet to be certified on the current RESO standards for data distribution, which is a huge problem. Even fewer MLSs have adopted the RESO data dictionary in the MLS system natively or the RESO update standard. What comes out of the MLS is different from what is input by the agent though the Add/Edit process. As I highlighted above, many MLSs do not ingest standardized data, they each have unique listing input schema and that is their intellectual property. And many of the largest MLS systems and MLS organizations still use RETS, a system that was built more than 30 years ago and, of course, never anticipated AI or other modern data distribution needs.

HomeServices said that it works across more than 250 MLS relationships. A national firm does not need to participate in every MLS to feel the cost of that fragmentation. I am pretty sure that RE/MAX brokers are in every MLS market in the nation. Even small brokers operating in 3 or 4 MLSs feel the pain to normalize information to prepare a listing to launch publicly.

Different local rules and enforcement processes can become impediments to a national operating system without MLS support. A brokerage may want a consistent listing workflow, training program and compliance process, while each MLS still requires its own workflows and policies to be honored. Standardizing the data fields is only part of the job. The brokerage must also manage the local conditions under which a listing is accepted, corrected and maintained.

That helps explain why national firms want more control at the point of entry. But a national interface does not create a national rulebook. Open Real Estate’s commitment to retain local MLS governance means its operating model must accommodate those differences through cooperation, rather than assume they disappear when a broker chooses new software.

A great starting point might be to create a standard MLS listing input payload where the listing would be completed in the MLS for 70% or more of local MLS fields. RESO has one.

Buying add/edit is not buying MLS cooperation

MLS cooperation is Open Real Estate’s, BLX and any other broker-centric listing initiation processes’ biggest hurdle. A vendor can supply listing-input software. It cannot, by itself, supply an MLS’s agreement to accept that input.

The listing-input process is more than a form. It embodies the MLS’s organization and coordination of data: field definitions, relationships, validation, cleaning, compliance, local business rules and the processes that keep records consistent. Our understanding is that this represents intellectual capital MLSs have developed and maintained at great expense over many years. That is distinct from a blanket legal claim that every field, rule or workflow is proprietary; specific intellectual-property and licensing rights depend on the contracts and materials involved. Open Real Estate will need a license from each MLS to use its intellectual property copyright for the organization and assembly of a listing contributed to the MLS.

Broker ownership of listing content does not, by itself, settle rights to use MLS-developed tools or the terms under which an outside system can submit data. MLSs may want to negotiate those terms rather than simply turn over the work behind their listing-input process. The practical questions include permission to implement local rules, maintaining changes, handling corrections, assigning responsibility for compliance and paying for integration and support.

This is not a hypothetical lesson invented for Open Real Estate. In its historical Upstream explainer, MRED said Upstream would need to fully implement MRED’s listing-input business rules and processes, and coordinate future rule changes. MRED would remain responsible for policing data and correcting fields. Its staffing burden would depend on how well the systems integrated. That is an operating relationship, not merely a data feed.

Open Real Estate says it will work alongside MLSs and leave local rule-making to all 484 of them. HousingWire reports that engaging the MLS community is among the founders’ next steps. Those statements describe an intention to cooperate, not a completed agreement. Giving MLSs a seat at the table is where the technology proposition becomes a negotiated operating model.

Without that cooperation in a given market, Open Real Estate could still operate as a separate broker data-sharing system and even become an MLS. If agents still have to maintain the listing separately in the MLS, the promised single point of entry remains unfinished. Existing production products improve the technical options; they do not make MLS participation automatic.

The BLX wrinkle remains

Two of Open Real Estate’s four founders are already BLX launch partners. Whether Open Real Estate complements BLX or competes with it remains an open question. Cotality, Ocusell, Bridge and MLS-developed tools illustrate the available technology landscape; naming them is not a claim that any has bid for Open Real Estate or agreed to participate. When we work with brokers or MLSs on vendor selection, the answer resolves to a single fulcrum, will the MLS accept the data from this source in the markets that matter to your business?

One question worth watching is whether MLS system developers bid to power Open Real Estate. Another is whether the founders select one platform or assemble services from more than one provider. The vendor decision should be judged on demonstrated coverage and operating performance, not merely on familiar names.

One last point. The vendors like Cotality, ICE, Rapattoni, Flex, etc. may expect to be paid for the burden of managing direct listing input from Open Real Estate and potentially others. It’s hard work, especially when you are running compliance on every listing submitted and updated.

What we will be watching

Negotiated MLS cooperation. Which MLSs have agreed to accept input, on what terms, and with what responsibilities for local rules, corrections and support? Without MLS support, Open Real Estate risks remaining a separate system rather than eliminating duplicate entries.
The vendor pick, expected in early 2027. Ask each candidate to demonstrate production add/edit, named MLS integrations, rule synchronization and support for broker-controlled distribution. Existing technology is an advantage only where it works for the intended participants.
The buildout – Today, Ocusell is live and operational around the country, but BLX and OpenRE are little more than press releases at this point. What technology will they choose, how long will it take to build out, how will it anticipate AI and how will it seamlessly integrate with MLS platforms?
The monetization mechanics. Proceeds shared equally per listing is a principle, not yet a model.
Compass. Invited, supportive in public, uncommitted. Its posture will shape whether Open Real Estate becomes industry infrastructure or a factional platform. In many markets, CIH brands carry ⅓ of the listings.
Large Independents – there’s no mention yet of powerful, regional independent brands that are key influencers in their markets as well.
There are over 80,000 brokers in America, but only about half operate in more than one MLS. I do not see the value yet for a broker who only operates in one MLS market. This group represents the largest body of participants in the MLS and it is not clear how they are served by Open Real Estate. It’s a question that has not been answered yet.

What this means for MLSs and brokers

The technology choices are better than they were in Upstream’s early days. The decisive question is whether MLSs become operating partners, not merely downstream destinations.

The structure is genuinely different from Upstream’s: no trade-organization partner, no in-house build, and founders who say they are prepared to invest significant capital. Structure alone, however, does not move an agent’s listing workflow onto a new system, and the announcements do not yet name MLSs committed to accept its input. Those are the proof points to watch between now and the Q1 2027 target.

For MLSs, the practical move is to engage early and define what cooperation requires, including the use and maintenance of their listing-input work. The founders are explicitly leaving local rule-making to local MLSs, which is both an invitation and a test. For brokers, the questions to ask at every presentation between now and Q1 2027 are practical: show us the production workflow, show us the integration, and show us which MLSs have said yes. If an MLS says yes to Open Real Estate, do they need to say yes to every broker who wants to build a competitive system to OpenRE.
