Let me say the quiet part out loud.
That shift is real, it is deliberate, and the industry needs to understand it clearly; not to condemn it, but to navigate
it.
What LiveRamp Actually Is
For those outside the plumbing of digital advertising, here's what you need to know. LiveRamp is (or was) the neutral data spine of the open
internet. Its RampID identity graph connects brands, publishers, retailers, and ad tech platforms in a shared language of privacy-safe audience identity. Its Authenticated Traffic Solution (ATS) sits
on roughly 80% of the top comScore publishers, converting logged-in readers and viewers into addressable inventory.

Its Safe Haven clean room technology powers the data collaboration between
brands and the largest commerce media networks in the world: Target's Roundel, Albertsons Media Collective, Walgreens Advertising Group, and dozens more.
LiveRamp's market value and its
credibility rested on one thing: neutrality. It was the Switzerland of data. It could sit in the middle of a transaction between a brand and a publisher, or between an agency and a retail media
network, precisely because it had no horse in any race.
After this acquisition, that neutrality changes.
The Publicis Stack, Assembled Piece by Piece
This
acquisition didn't happen in isolation. To understand it, you have to see the full architecture Publicis has been deliberately building—layer by layer, year by year—in response to a
constellation of forces reshaping the marketing industry: the collapse of third-party cookies, the arms race around first-party data and identity graphs, increasing privacy regulation, the demand for
greater advertising accountability, and the need to build technology infrastructure that creates durable competitive advantage beyond labor-based services.
- Epsilon (2019, $4.4B):
Deterministic identity and CRM activation; 2.3 billion consumer profiles.
- CitrusAd (2021): Retail media technology; the ad serving stack powering major retailer sites.
- Profitero (2022): Commerce intelligence and e-commerce analytics.
- Lotame (2025): 1.6 billion additional global identifiers and DMP capabilities.
- LiveRamp (2026, $2.2B): Open-web identity infrastructure, 25,000+ publisher relationships, the leading clean room platform.
Add Publicis Sapient for engineering, Marcel as
the internal AI activation layer, CoreAI as the operating system, and a deep Nvidia partnership, and you have something that no longer resembles a traditional advertising agency. It looks like a data
and technology company that also manages advertising.
Combined, Publicis now claims approximately 4 billion consumer profiles covering roughly 91% of adult internet users globally. That is a
footprint that rivals the major technology platforms and it is controlled by a company that also decides where billions of dollars in client media budgets flow every year.
Now, I want to be
clear about something: I am not against this direction. The industry has debated principal media and the broader shift toward proprietary data and owned technology platforms at length. There are
legitimate tensions.
There are also real benefits: scale, efficiency, identity resolution, and measurement precision that some clients genuinely value and cannot easily replicate elsewhere.
The question is not whether this model is good or bad. The question is whether clients understand the difference between this model and one grounded in true neutrality—and whether they are
choosing accordingly.
The Neutrality Shift Is Now Infrastructure-Level
What makes LiveRamp categorically different from prior Publicis acquisitions is its position in
the ecosystem. Epsilon was a Publicis asset from the moment it was acquired. The market understood that. LiveRamp is infrastructure that the entire industry, including Publicis's competitors, their
clients, and the publishers serving both, was built around.
Publishers embedded LiveRamp because it was a shared, trusted layer. Retail media networks built their clean rooms on it because it
was independent. Brands shared sensitive first-party data through Safe Haven because the platform had no agency parent with a stake in the measurement outcomes.
That architecture now has a new
owner, and the implications are concrete.
Premium CTV and streaming publishers such as NBCU, Disney, Paramount, Netflix, and others have embedded ATS and LiveRamp's clean room into their
cookieless monetization infrastructure. Those same publishers negotiate annual deals against Publicis's buying agencies on behalf of major advertisers. They now share their most valuable asset --
logged-in subscriber identity -- through infrastructure owned by their negotiating counterpart.
Publicis has pledged that LiveRamp will remain a neutral, interoperable platform. That pledge
deserves credit. But the history of similar assurances post-acquisition suggests the market will remain skeptical, and rightly so.
Retail media networks like Target's Roundel, Albertsons Media
Collective, Walgreens Advertising Group, and others built their commerce media businesses on the premise that independent measurement is the value proposition to supplier-advertisers. When the clean
room connecting a CPG brand's campaign to purchase data is owned by the same holding company managing that CPG's media, the measurement independence claim has an asterisk regardless of contractual
language.
Brands and CMOs everywhere should be auditing their data collaboration arrangements. Where does your first-party data live? Who has access to your clean room outputs? If your agency
owns the measurement infrastructure, what governance and transparency standards apply?
The Bigger Strategic Picture
I genuinely respect what Publicis has built. The
strategic coherence behind the Epsilon– CitrusAd–Profitero–Lotame–LiveRamp sequence is impressive. Arthur Sadoun has been executing against a clearly articulated vision, and
the financial results, including sector-leading organic growth and record new business performance, validate the thesis.
But it is worth naming what the thesis is: Publicis is building a
business transformation and technology company, not a modern integrated advertising agency. Advertising is increasingly the distribution channel for a platform play, not the core product.
That
is a legitimate and, for the right clients, compelling model. Large enterprise brands with complex, global marketing operations may find that an integrated partner with proprietary identity, commerce
intelligence, AI infrastructure, and media execution delivers more value than independent specialists operating at arm's length.
But not every brand is a global enterprise. And not every brand
wants or can afford an integrated model where the same partner owns the data, executes the media, measures the results, and earns margins at multiple layers of the stack.
The Door This
Opens
As the major holding companies -- Publicis, Omnicom post-IPG, and WPP -- consolidate proprietary data assets and build vertically integrated stacks, they are simultaneously
vacating a different kind of market position: the trusted, neutral advisor.
There is a growing segment of sophisticated brands that actively values independence. That wants an agency partner
whose counsel is not shaped by proprietary data investments, principal media programs, or owned technology platforms generating margin at multiple points in the supply chain. That wants to know that
the recommendation to use Platform A over Platform B is grounded in what is best for the brand, not what is best for the holding company's P&L.
Independent agencies and advisory firms that
can credibly offer that posture will find the market increasingly receptive. Not because they are cheaper, but because they offer something the scaled holdcos are structurally less able to provide:
genuine neutrality, transparent economics, and counsel that is fully aligned with the client's interests.
The end of the neutral middle at the infrastructure level does not have
to mean the end of neutral counsel at the client level. It does mean that the gap between the two models: integrated and proprietary versus independent and transparent, will widen, and the choice
between them will matter more than it ever has.
The Publicis–LiveRamp deal is not an indictment. It is a strategy—audacious, well-executed, and internally
consistent—that will serve a specific kind of client very well.
But strategy has consequences for the ecosystem around it. The neutral infrastructure layer that publishers, brands, and
competing agencies relied on has been absorbed into one of the three largest holding companies on earth. That changes the math for everyone — on data governance, on measurement trust, on how you
choose an agency partner, and on what kind of partner you need.
The neutral middle is gone at the infrastructure level. The question now is who fills the advisory gap it potentially leaves
behind.
