Publicis's LiveRamp deal makes agency neutrality harder to sell

Publicis wants to own a data connector used by companies it competes with. Today it can beat those companies in a pitch. If the LiveRamp deal closes, it could also control part of what it costs them to serve the client. That is an awkward position for an agency group selling independent advice.

Publicis has offered $2.167 billion enterprise value for LiveRamp, a business that reported $813 million in FY2026 revenue. The offer is about 2.7 times revenue. Publicis paid $4.4 billion cash for Epsilon in 2019.

Publicis paid to own Epsilon and has made another offer for data infrastructure. The proposed deal would put the group across the data that helps find a customer, the agency that recommends where the media budget goes, and the connector that lets outside companies exchange information. It would put the agency group across both the decision and the infrastructure behind it.

I have sold media plans and bought media for a brand. An agency’s recommendation moves money. The platforms selling that media also shape the audience, auction and measurement inside their own systems. We treat that integration as normal product design. When an agency buys the shared connector other agencies depend on, the neutrality question becomes urgent.

LiveRamp sits upstream of the media pitch

The FTC’s October 19 complaint lays out why the transaction reaches beyond one company’s client list. It separates media agency services, audience data services and data connectivity services into three markets. Publicis works in the first two through its agencies and Epsilon. LiveRamp works in the third.

That third market matters because the FTC calls LiveRamp the leading US provider, says it has the largest scale and a full range of connectivity services, and says some competing providers rely on its infrastructure. Building a replacement at similar scale would be difficult and costly, the complaint says.

This is where the commercial risk starts. A brand may hire WPP or Dentsu to buy media, use a data supplier outside Epsilon, then need LiveRamp to connect the audience information to the media system. If Publicis owns the connector, the company that competes for the agency account also controls part of a rival’s route to do the work.

The FTC alleges that Publicis could use confidential client or competitor information to win agency business, or deny or degrade access and raise rival data providers’ costs. A rival agency could lose an account through a service disadvantage before it gets to defend its media recommendation. Its offer could become slower, more expensive or less complete because its critical connector belongs to the competitor that wants the client.

Owning an ad placement gives a seller control over its own inventory. A shared connector can affect the cost of service for rival agencies before a media recommendation is even made. Rebuilding audience connections and measurement paths takes work, and the FTC says LiveRamp’s scale makes entry difficult.

Platforms sell inside their own systems too

Google’s Customer Match and Meta Custom Audiences let advertisers use customer records to reach people within each company’s media products. Amazon’s advertising platform combines sponsored ads and programmatic campaigns around shared signals and measurement. The platform owns the buying interface and sells the inventory. It is both a media choice and the place where some of the evidence about that choice is produced.

The scale is not subtle. In 2025, Google reported $294.7 billion in advertising revenue, Meta $196.2 billion and Amazon $68.6 billion. Each has a direct financial interest in making its advertising system work. A platform sells the media and the tools needed to target and measure it under one roof. Buyers accept that as the product. The same buyer data can move through an agency, a data firm and a platform, yet the neutrality question usually lands first on the agency.

Platforms have faced rules where control over connected systems created competitive advantages. In September 2026, the US Department of Justice said a federal court ordered Google to integrate AdX and DFP with Prebid and rival publisher ad servers, let publishers access and export their own data, and stop AdWords from bidding preferentially into Google-owned ad-tech tools. A monitor and technical committee will oversee compliance for six years, according to the DOJ’s account of the judgment.

Europe’s Digital Markets Act also gives advertisers and publishers rights to access the tools and data needed to verify ad performance. The European Commission’s business-user guidance explains those access and measurement rights. In 2025, the Commission fined Meta €200 million over its EU choice between cross-service personalized ads and a monthly fee. That consumer-data case differs from an agency’s use of campaign data, but it shows Meta’s data combinations are regulated too. Amazon has accepted a separate Commission commitment not to use non-public marketplace seller data in its own competing retail business, under the Commission’s binding decision. That case concerns marketplace sellers. It shows the same conflict: an intermediary sees business data while competing with the businesses it serves.

Platform rules already exist. Google has been required to open parts of its ad-tech stack to rivals and let customers take data with them. The gap is in how buyers talk about integration. A platform’s ownership of the auction, audience and report is described as convenience. An agency’s ownership of the connector becomes a competition issue because rival agencies depend on it.

A grocery campaign shows what a connector is worth

When Mondelēz wanted to measure a Triscuit campaign, Pinterest had the ad exposure, Albertsons had purchase records, and off-site display ran through Google’s DV360. LiveRamp’s published case study says the six-week campaign connected those views and reported 16% incremental sales and units, with 19% more buyers.

That is the CPG problem in plain terms. Pinterest can tell a brand who saw an ad. A grocery retailer can tell what its shoppers bought. Neither has the full answer. The brand needs the connector to see whether its media moved the product.

The value is in joining evidence held by companies with separate interests. The same connection can tell an agency how a campaign performed, help a data provider build audiences, and help the brand decide where its next dollar goes. The company controlling that connection gains a view of the market beyond its own media placements.

That is why the Epsilon history matters. Publicis paid $4.4 billion cash for a company whose loyalty software served 600 million accounts. It now proposes to buy a connector used across other agencies and data providers. A client’s media plan, audience source and sales measurement can converge inside one holding company, while the rivals who serve that client need the same connector to compete.

The loss shows up in the next agency pitch

Publicis says the acquisition will help clients connect data across publishers and technology partners. That is a real benefit. A brand gets less value from scattered data that cannot be matched or measured. But the value of the network depends on rivals continuing to use it, and the value to a buyer depends on being able to move its work if the service or price stops making sense.

If competitors leave LiveRamp because they cannot trust an owner that also competes for their accounts, the network gets less useful to everyone. If they stay, they share a crucial input with their largest rival. Either way, Publicis gains a strategic advantage in pitches: it can offer agency services, audience data and the connective path that makes the campaign measurable, while competing agencies must explain why the shared system remains neutral.

That is the commercial asymmetry. Google, Meta and Amazon sell media through their own systems and face rules when control of those systems distorts competition. Publicis would own infrastructure that helps other sellers work across the market. If a rival agency gets slower service, a higher price or a thinner measurement path, the brand’s next pitch is tilted before the agency recommends a single placement. The owner of the connector has already changed who can compete for the account.
