Open Real Estate: the first three business days on LinkedIn
The volume was high and positive, but nearly half of it came from people inside the founding companies. Outside that circle the reaction was more measured, and the posts with real substance were close to neutral.
What a Rapid Reaction Scan is
- An early read of how the industry is reacting in public, usually within 24 to 72 hours of an announcement.
- A structured sample of LinkedIn posts, each scored for sentiment, grouped by who's posting, and separated into signal and noise.
- A pointer to where meaningful positions, risks, and open questions are forming.
What it isn't
- Not a survey, and not a representative measure of industry opinion.
- Not a census. LinkedIn limits how deep anyone can search, so this is a sample.
- Not a prediction, and not a verdict on the initiative itself.
- Not a substitute for research. Decisions should rest on data and direct conversations; this shows where to look first.
What the Rapid Reaction Scan is showing us
The conversation is still open. The enthusiasm is concentrated inside the founding companies, the voices with real standing are split, and the comment threads started out skeptical. Positions are still forming, which means they can still be shaped.
Three questions will influence how this lands.
- Does the MLS still own listing submission? If listings can enter through Open RE, MLSs make their case on rules, data quality, and service, starting with the question the comments kept asking: who validates the data and stands behind it?
- Will independent brokers buy in? They're the most skeptical group, asking whether another network fixes fragmentation or just moves control.
- Will the rules hold up to antitrust scrutiny? Critics say national rules set by the largest firms invite challenge; supporters say open membership answers it.
Underneath all three is how the Participant view will be governed: listings that members can see but the public can't. That's where to focus, rather than the open-vs-private debate most posts are having.
What shifted
- Day 4The comments warmed. The first read ran net −10; with the 72+ re-read the comments net +5 on 39 comments. A small sample, so directional.
The numbers behind it: 78 of 180 posts came from the founding companies' own people, running net +90 on largely shared talking points. Everyone else runs net +22. The 22 posts with real substance net +5, and the typical one draws three times the reactions of a typical echo post (median 3 vs. 1). The comments read at the first checkpoint ran net −10; a 72+ re-read added a handful of mostly positive comments (details below).
Rapid Reaction Scan Sentiment Scoreboard: how reaction moves in the first 72 hours
Every Rapid Reaction Scan adds a row, so reactions to different events can be compared over time.
How to read net sentiment
The share of positive posts minus the share of skeptical ones. At +50, positive posts outnumber skeptical ones by 50 points. At 0 they balance. At −100, every post is skeptical.
| Event | Announced | Read | Posts scored | Net sentiment, all posts | Net sentiment, outside the founding companies | Net sentiment, real substance (indicators) |
|---|---|---|---|---|---|---|
| Open Real Estate launch | Oct 26, 2026 | 72+ hours81h · Thu 7 pm MT | 180 | +514 down 4 from 48+ | +224 down 4 from 48+ | +56 down 6 from 48+ |

▲ / ▼ show the change from the previous checkpoint. Net sentiment = % positive minus % skeptical, on a −100 to +100 scale. Each row is cumulative through that checkpoint. The 24+ row is rebuilt from post timestamps; a few posts near the boundary are approximate. Across the three checkpoints, all posts and outside the founding companies were stable, each easing six points in total. Real substance moved from 0 to +11 at 48+ and eased to +5 at 72+, as three new indicator posts came in, two of them skeptical. The scan closed at the 72+ checkpoint.
Net sentiment by stakeholder group
Share of each group's posts by sentiment toward Open RE. Positive reads left to right; groups sorted by average sentiment.
No post in the set was outright hostile. Opposition shows up as skepticism about power, antitrust exposure, and whether another network fixes fragmentation.
Noise vs. indicator
Each dot is a post, placed by sentiment and by how much real substance it carries. Dot size reflects reactions at capture time. Hover or tap for the post.
Top row: reactions on the typical post (median). Bottom row: averages, which run higher because a few widely shared posts pull them up, most of all the two corporate launch posts among the noise.
For context: these counts are modest by LinkedIn standards and were captured while posts were still accumulating reactions. The point is the comparison between tiers, not the absolute numbers.
What the comments say
The default comments shown on the 10 most-discussed posts, read the morning of Oct 28: 31 comments, not counting post authors' replies.
72+ re-read (Oct 29, 7 pm MT): the default comments on the most-discussed posts were largely the same as the first read. Eight we hadn't read before leaned positive (five positive, three neutral or questions, none skeptical), including a former state real estate commissioner's support and a question about who owns the data. Added to the first read, the comment net moves from −10 to +5 on 39 comments. That's a small sample, so treat it as directional.
Independent cross-check (Oct 30): a separate capture read 35 comments on a different set of ten threads, including three corporate announcement threads. It nets about +17, lifted by vendor and founding-brand congratulations, so it points the same way as our re-read; it isn't merged because the threads differ. It surfaced two comment-level findings: commenters who would rather standardize RESO Add/Edit across MLSs than add another intermediary, and the first openly hostile language in either capture ("cartel"). No post in either capture was hostile.
The posts are where people announce a position. The comments are where people test it, and that is where the doubts surfaced first.
Doubts about motives and staying power (7)
"A gimmick to deal with a gimmick." "Incumbents protecting their turf?" Two predicted it fails. A Compass agent's reply: "You know what they say about imitation."
Who validates the data? (4)
The most substantive thread. If Open RE distributes a listing before the local MLS validates it, who owns accuracy, corrections, and violations? A standards-organization CEO agreed that direct input "gets complicated much more quickly."
"Isn't this what the MLS does?" (3)
Agents and a brokerage president asked it directly. The founding-company franchisor president's answer: one entry point instead of hundreds, brokerage data monetization, and rules enforced evenly.
MLSs should restructure, and one says it already has (3)
On the MLS systems advisor's post, an MLS CEO replied, "We just did it." A former national portal CEO added that the window for MLSs "won't stay open forever."
Friction from inside a founding company (2)
An agent at one of the founding companies asked what the advantage is. He raised double entry, field mapping, and a one-business-day rule that lands before photos and staging. If his MLS doesn't cooperate, he said, he'd have to pick between his brokerage and a second MLS.
Smaller threads
A standards-organization CEO pushed back on the antitrust concern: every broker can join. Others raised governance as the real test, whether data vendors will pay, whether it has to be consumer-facing, and a name collision: to this industry, "ORE" already means organized real estate.
Themes, by signal
How often each theme came up, split by indicator/watch posts vs. noise. Consumer exposure and private listings are the talking points; MLS future and execution gaps are where the analysis is.
Six threads worth following
How we found these: we grouped the 45 posts rated Indicator or Watch by topic and picked out the threads with the most substantive discussion behind them. They reflect what people posted publicly in the first days. Comment themes are summarized separately above. Early threads aren't predictions: some will fade and new ones will surface as details come out.
The Participant view is where the substantive discussion is
Open RE doesn't eliminate private listings. It pools them among members, under shared rules. A founding-company franchisor president confirmed that sellers can choose a Public or Participant view. A trade-media executive called the Participant view "a private listing network between all of Compass's biggest competitors," and a Compass-family agent quoted by Inman made the same point as a criticism.
The MLS question reached MLS boards within a day
One consultant's framing is being repeated widely: if submission, normalization, and distribution live in Open RE, is local rulemaking enough of a business? An MLS systems advisor is telling MLSs to restructure now, another consultant is already pitching MLS boards, and a broker network leader says Open RE fails without MLS cooperation. The counterweight: the CEO of a large Midwest MLS publicly welcomed Open RE as consistent with the MLS cooperation principle. On day three, a state REALTOR® association president asked brokers whether they would enter a listing in a shared platform before it reaches the MLS. On day four, an MLS systems advisory firm called it "right goal, wrong vehicle," proposing to strengthen existing MLS data delivery instead.
Independent brokers are the most skeptical group
Independent broker-owners are asking how another network fixes fragmentation and whether this is just a different set of large companies controlling inventory. Some independents do support it, including a buyer-focused broker-owner who wrote on day three that she is rooting for it and a small brokerage owner who says he signed up the day it was announced, so the group isn't uniform. On day four, the founder of a large independent brokerage wrote that "the industry is eating itself alive."
Antitrust and the Upstream comparison came up early
An industry attorney and former CEO flagged antitrust risk: in his view, national distribution rules written by the largest firms will draw scrutiny from anyone who loses under them. Several posts also compared Open RE to Upstream, an earlier broker-led listing-data effort.
The Compass side isn't speaking with one voice
Reactions from Compass-family agents range from counter-narrative ("defensive alliance from legacy brands") to a hedged "consumer first" to neutral news roundups. Advocates are also elevating a Compass agent who publicly questioned the company's direction. Some posts point out that Compass's CEO praised Open RE while Compass is suing MLSs over looser rules.
The coalition is widening at the edges
Lamacchia, Iron Valley, Brown Harris Stevens, and smaller firms signed letters of support within the first day. One signer's statement adds a point most founding-company posts didn't emphasize: seller choice matters, including legitimate privacy needs.
What the noise looks like
"Noise" isn't a judgment on the people posting. It means a post mostly repeated or promoted the announcement rather than adding new information: shared talking points, brand reposts, explainers, and content hooks. It's most of the volume (135 of 180 posts, net +64), which is why the headline numbers run more positive than the posts with real substance.
Founding-company reposts
Mostly founding-company agents reposting the four principles and the open-letter quote, often with a "DM me" or "comment below" call to action.
International interest
International agents in Italy, Spain, Brazil, Poland, and Luxembourg are already using it as a model for their own markets.
Vendor content hooks
Vendors are using it as a hook for webinars and AI pitches.
Details that don't match
Two posts include details that don't match the founders' statements: one says rollout is "late 2027," another calls Open RE a "portal."
Day 2: what changed overnight
Day updates show what changed after the first read, so the report keeps a running record as reaction develops. Day two adds 20 posts, most published overnight after the first read. That's a smaller sample than day one, so treat any shift as directional. The cards below cover what's new rather than repeating what's already above.
The founding companies are a smaller share of the conversation
8 of the 20 new posts came from the founding companies' own people (40%, down from 44% on day one). Everyone else ran net +50 on day two, warmer than day one, though on a small sample.
The Participant view already exists at the MLS level
A Milwaukee boutique broker pointed out that her MLS already runs a members-only portal of excluded listings (138 homes, per her post), and that a new state law protecting informed seller privacy takes effect January 1. Member-visible, public-hidden listings already exist at the MLS level; Open RE would extend the concept nationally.
The "once marketed" line is getting sharper
On the 9-CEO podcast released yesterday, a founding-company executive put the rule plainly: a seller can keep a home private, but once it's marketed, every buyer and every brokerage gets the same access. Several posts point to that line as the key test for the Participant view.
Day-two analyst reactions: cautiously optimistic, with caveats
A veteran industry analyst called it "a real positive sign, but one fraught with pitfalls." A proptech CTO called it "another wake-up call" for MLS data distribution. On the other side, an activist agent called Participant-only distribution "an even bigger private club."
Day 3: what changed during the second business day
Day three adds 32 posts published during Wednesday's business day, up to the 48+ checkpoint. As with day two, it's a smaller sample than day one, so treat any shift as directional. The new posts drew few comments (15 across all 32), too few to score; comments are re-read at the 72+ checkpoint.
The founding companies are back near half of new posts
15 of the 32 new posts came from the founding companies' own people (47%, up from 40% on day two). The other 17 ran net +12, cooler than earlier days, though on a small sample.
An association leader joins the conversation
A state REALTOR® association president and broker-owner laid out what was announced, noted that no MLS in his state is a party to it, and asked brokers directly whether they would enter a listing in a shared platform before it reaches the MLS.
Feasibility questions move to the front
An industry podcast discussion put long odds on success and doubted a first-quarter 2027 launch, while one host called it a national MLS in effect. A strategy consultant argued participation, not technology, is the hard part, and a non-founding brokerage growth lead asked "who's really running the show?"
Founding-company voices push back on the labels
A founding-company executive wrote that Open RE is not another portal and that the problem is data standardization and syndication. Meanwhile, two posts include details that don't match the founders' statements: one calls it an MLS and one says it has already launched.
A new argument: fair housing
A podcast clip from a participating-brokerage CEO framed listing transparency as a fair-housing issue, arguing that listings kept inside one brokerage can create new barriers to housing access.
Day 4: what changed during the third business day
Day four adds 23 posts published during Thursday's business day, up to the 72+ checkpoint, which closes the scan. Volume is tapering, and it's a small sample, so treat any shift as directional.
Fewer posts, and fewer of them from the founding companies
9 of the 23 new posts came from the founding companies' own people (39%, the lowest share of any day). The other 14 net −7: slightly more skeptical posts than positive ones.
"Right goal. Wrong vehicle."
An MLS systems advisory firm agreed with the aim but proposed strengthening existing MLS data delivery instead of building a new national platform. The founder of a large independent brokerage went further, writing that "the industry is eating itself alive" and that consumers could be the biggest losers.
A small brokerage says it signed up
A small independent brokerage owner in Washington says he signed his firm up the day Open RE was announced. His framing: private can be right for a specific seller, but it shouldn't be the default.
Data rights and legal questions from the MLS side
A former MLS general counsel who works on data licensing asked who will really control the data, how the platform will make money, what monetizing data means for consumer privacy, and how much antitrust attention it will draw.
Who's missing, and who says it's already built
Trade coverage asked why Howard Hanna, a large regional brokerage, wasn't on the launch list. A listing-distribution vendor says it already built single-entry distribution for that brokerage, and that single entry still needs MLS buy-in and each MLS's full ruleset. A Canadian trade magazine argued Canada already has much of what Open RE is trying to build.
Considerations for MLS, association, and brokerage leaders
Lead the explanation of Public vs. Participant view. Most posts collapse Open RE into "open vs. private." The actual design pools private listings among members. Leaders who can place it clearly on the range of listing exposure, from MLS public to office exclusive to brokerage-private marketing, become the trusted source for their members and brokers.
MLS boards: be the answer to "who validates the data?" That was the question the comments kept coming back to. Whether listings enter through the MLS, Open RE, or both, rules, compliance, data quality, and service are where the MLS adds value, and the time to show it is now, while the design is still taking shape.
Read past the volume. Nearly half the posts came from the founding companies' own people. The posts with real substance are close to neutral, which means the conversation is still open and worth shaping.
Know where your independents stand. They're the most skeptical group and the least measured. A short member or subscriber pulse turns anecdotes into a number.
Added Day 4Be ready to show the alternative. An MLS systems advisory firm proposed strengthening existing MLS data delivery instead of building a new national platform. MLSs that can show what that looks like in practice give brokers a concrete comparison, not just an objection.
What would move these indicators: the first MLS letters of support, Participant-view governance details, Compass's decision to join or stay out, and the technology vendor selection.
Considerations for proptech providers
The near-term opening is the build. Open RE plans to pick outside vendors to build its database, interface, and APIs in early 2027. The questions technologists raised in the first day are the spec gaps a winning bid has to answer: duplicate listings, conflicting updates between brokerage systems and MLSs, and permissions.
MLS system vendors: plan for the possibility of a second front door. If listings can enter through Open RE as well as the MLS, two-way sync, data-quality ownership, and which record wins in a conflict become product questions, not policy questions. Standards work matters more, not less.
Tools that sit on listing input or marketing need a Participant-view plan. A listing that is visible to members but not the public has to be handled correctly in every system downstream: CMAs, showing tools, CRMs, marketing automation, and AI search features.
Updated Day 4Watch the economics and the rights. A broker-owned data layer that shares revenue per listing changes who you license from and negotiate with. Media rights came up early too: what happens to photos, video, and 3D tours when distribution runs through a new layer. On day four, a former MLS general counsel who works on data licensing asked who will really control the data and how the platform will make money.
In the first days, most vendor posts used Open RE as a content hook for webinars and AI pitches. The vendors who stood out asked specific build questions.
How this scan works
Rapid Reaction Scans sample public LinkedIn posts about an event within its first 24 to 72 hours. Each post is scored for sentiment toward the event on a five-point scale, grouped by who's posting, and classified as an indicator (real substance: rules, adoption, or a stakeholder leader's stated position), a watch item (credible, not yet confirmed), or noise (echo and promotion). Net sentiment is the share of positive posts minus the share of skeptical or negative ones, on a −100 to +100 scale. Results are independently cross-checked. They show early reaction, not a representative survey.
This read: 180 unique posts in four captures (Oct 27, 2:45 pm; Oct 28, 7:15 am; Oct 28, 7 pm; and Oct 29, 7 pm MT). The scan closed at the 72+ checkpoint; after that, only a material event (an adoption, a refusal, a rule change) gets a follow-up, after removing off-topic matches and duplicate copy posted across accounts. Three posts that shared or featured twenty-two's own work were left out. Comments: the default comments shown on the 10 most-discussed posts, 31 excluding authors' replies at the first read, plus 8 not previously read at the 72+ re-read; not every comment. "Founding companies" means the corporate accounts, agents, and staff of AGNT (eXp Realty, NextHome), Keller Williams, HomeServices of America, and Real/RE/MAX, plus signer brokerages and one dedicated advocate. Reaction counts are as displayed at capture, so the newest posts have had less time to collect them. Day two was cross-checked against an independent capture as well; the two agreed on sentiment direction for every overlapping post. A second independent capture on Oct 30 (31 posts and 35 comments, taken after the window, with rounded post ages) overlapped with about 27 of our posts. No post was coded in opposite directions; differences were neutral versus mild sentiment and six signal tiers. Two of our codes changed as a result: a brokerage owner who signed his firm up now counts as a signer, inside the founding-company circle, and an advisory firm's proposal moved from indicator to watch. It found one in-window promotional post we missed, noted rather than added. Neither capture is exhaustive, and its ten comment threads were selected from posts it found, not LinkedIn's verified top ten.
Checkpoint timing. Each scan reports at three checkpoints: 24+, 48+, and 72+ hours. Each checkpoint is the first end-of-day capture (7 pm MT, so the Pacific workday is complete) after at least 24, 48, or 72 hours have passed since the announcement. That way every checkpoint includes at least one full business day of reaction, whatever time the news broke. Weekends and holidays pause the clock. The scoreboard shows the actual elapsed hours for each checkpoint. Posts are assigned to checkpoints by publication time; LinkedIn shows age in whole days after 24 hours, so a few posts near a boundary are approximate.
How twenty-two Intelligence uses AI
AI does the heavy lifting on collection and first-pass sorting. That's what makes a read of 180 posts and their comment threads possible within days. The framework, the scoring rules, the calls on what counts as signal versus noise, and the interpretation are ours, built on years of working inside organized real estate with MLSs, associations, brokerages, and the technology providers that serve them. Every scan is cross-checked against an independent capture before it's published, and every read is one we're prepared to stand behind.
Appendix: every post, by role
Posters are described by role and relationship to the event, not by name.

Revision history
At every checkpoint, each finding is re-tested against the new data and marked as holding, shifted, or new. A shift means a headline number moved 10 or more points or changed sign, comments changed direction, a stakeholder group took or reversed a position, or a material event occurred.
- 24+ · Oct 27First read, 115 posts. Verdict, three questions, threads and considerations written.
- 48+ · Oct 28157 posts. Day 2 and Day 3 cards added. Real substance rose to +11. Verdict and three questions reviewed; they held.
- 72+ · Oct 29180 posts; scan closed. Day 4 cards added. Comments re-read (−10 to +5) and real substance back to 0, noted under What shifted. Two threads and one proptech consideration updated; one MLS consideration added.
- Oct 30Sentiment scale, checkpoint change markers, condensed appendix and this review format added. Headline re-checked against the final read: "most" of the volume corrected to "nearly half" (77 of 180 posts came from the founding companies), and the line now reads as the closed three-day read. No change to the data.
- Oct 30 · cross-checkReviewed against an independent capture. Two recodes: a signed-up brokerage moved into the founding-company circle (78 of 180), and an advisory firm's proposal moved from indicator to watch. Real substance at 72+ is now +5, a 6-point move from +11, below the shift bar, so it's no longer listed under What shifted. Day 4 card and comment findings updated; conclusions unchanged.
