Ice Cold Cola Wars

Publicis choosing PepsiCo over Coca-Cola isn't so much a story about two rival drinks brands. It is a story about the increasingly uncomfortable collision between agency conflicts, holding-company economics and the industry's desperate attempt to reinvent itself around data, technology and AI.

There are moments when the advertising industry accidentally writes its own satire.

Publicis winning PepsiCo's global media account, reportedly without a formal pitch, would have been enough of a story on its own. After more than twenty years with Omnicom's OMD, PepsiCo is moving to a global model spanning media strategy, planning, activation, connected identity, data, technology and AI across more than 200 markets.

Then came the other bit.

Publicis withdrew from Coca-Cola's global media, data and technology review.

The reason is not particularly mysterious. PepsiCo and Coca-Cola are competitors in a category where the phrase "conflict of interest" sticks like sugary syrup.

Publicis already handles Coca-Cola's North American media business, having lifted it from WPP in 2025. It was now competing for the broader international relationship, as hopeful of winning the business as can be reasonably expected. Then Pepsi came along. And well, Publicis chose to go with Pepsi.

Suddenly, a global agency review became a speed dating spectacle.

This is rational. Which is precisely why it is awkward.

It is tempting to portray Publicis as having committed some spectacular act of corporate treason, but that would be lazy thinking.

From Publicis' perspective, the decision makes considerable commercial and strategic sense.

PepsiCo wasn't simply offering another media account. Its new model aligns remarkably closely with the proposition Publicis has spent years building: the convergence of media, data, identity, technology and AI into a more integrated marketing operation.

And unlike the traditional agency pitch, PepsiCo apparently didn't require Publicis to spend six months producing elaborate PowerPoint presentations to prove it could do the thing it had already demonstrated it could do.

PepsiCo saw the capability in the market, wanted the capability, then offered to purchase the capability.

There is something refreshingly brutal about that.

If you are Publicis and one of the world's largest advertisers says, effectively, "We like what you've built and we want you to provide it to us globally," walking away from a competing fractional opportunity is hardly an irrational decision.

Especially when the competing opportunity is for the other half of the world's most famous cola duopoly.

The important point is that Publicis appears to have decided that the Pepsi opportunity was worth more than continuing to compete for Coke.

A bird in the hand so to speak. That is a commercial decision.

But commercial decisions can still have consequences.

Coca-Cola is entitled to be annoyed

Put yourself in Coca-Cola's shoes.

You are running a significant global review covering media, data science and technology.

Publicis is participating.

You already have a relationship with Publicis in North America.

You are presumably evaluating which organisation can help you navigate a marketing environment increasingly defined by data, technology, automation and AI.

Then your biggest global competitor engages your prospective partner and your competitive leverage exits your pitch leaving you with zero options. Dammit, I hate it when that happens.

It is difficult to imagine a more effective way of reminding a client that, underneath all the talk of transformation, ecosystems and connected capabilities, agencies are still businesses making commercial choices.

Coca-Cola can hardly object to Publicis taking PepsiCo's money.

But it can reasonably ask what that decision says about the nature of the relationship it thought it was building.

Because this is where the traditional holding-company model starts to look rather less elegant.

The industry has spent decades explaining that competitive conflicts can be managed through organisational structures, information barriers, separate teams and confidentiality agreements.

Technically, perhaps they can. But Coke and Pepsi aren't two obscure regional B2B professional service companies.

They are Coke and Pepsi.

At some point the question stops being whether a conflict can be managed and becomes whether either client actually wants its agency managing the other side of the battlefield.

Publicis appears to have answered that question, possibly once and for all.

WPP can't be written off

The obvious narrative now is that WPP is forever the bridesmaid.

That would also be too simplistic.

WPP has been Coca-Cola's global marketing partner since 2021 and built Open X around the relationship. Coca-Cola subsequently renewed the broader partnership, citing the value WPP was delivering.

WPP also remains deeply embedded in Coke's global creative operation.

It would therefore be lazy to conclude that Publicis's withdrawal somehow proves WPP is incapable of competing in the new world.

In fact, WPP has spent enormous amounts of money and organisational energy trying to position itself precisely for this new world.

Its challenge is different.

WPP is attempting to transform a huge, complicated organisation while carrying the accumulated baggage of being a huge, complicated organisation.

That matters because when an incumbent talks about transformation, clients inevitably ask whether they are looking at genuine transformation or simply the existing machine with a fresh coat of AI paint.

That doesn't make WPP bad, it makes being an incumbent super bloody difficult.

And if Coca-Cola ultimately decides that it wants something fundamentally different from what WPP has historically provided, that will say as much about the client's changing needs as it does about WPP.

The economics behind the theatre

This is where ADOTAT's Pesach Lattin has been particularly interesting.

Lattin's reporting and commentary have focused attention on the commercial logic behind Publicis's decision rather than simply treating it as an agency soap opera.

That distinction is seriously on point.

Publicis isn't walking away from Coca-Cola because Coke suddenly became an unattractive client. It is making a choice about which opportunity is strategically more valuable. That is a much bigger story.

The holding companies have spent decades constructing organisations designed to convince clients that they can handle pretty much anything.

Global scale.

Regional delivery.

Specialist expertise.

Integrated services.

Data.

Technology.

Creative.

Media.

AI.

Category knowledge.

Category neutrality.

And for the most part, they have become extraordinarily good at building organisational structures capable of making those claims technically true.

But there is a fundamental contradiction hiding underneath it.

You can build all the firewalls you like. You cannot firewall perception.

When the two biggest cola companies are involved, nobody really cares how beautifully the organisational chart has been designed. It’s tribal and each wants to know whose warpaint you're wearing.

Maybe, hopefully, the agency pitch may be a casualty

There is another detail in this story that deserves considerably more attention.

PepsiCo apparently didn't need a traditional pitch, it chose Publicis based on capability and strategic fit. That should make Adland profoundly uncomfortable because love it or loathe it, the pitch is one of advertising's most cherished rituals.

Agencies complain about it. Clients eyeroll their way through it. Procurement gets unreasonably excited about discounting it.

But everyone turns up and does it anyway.

Months are spent creating credentials decks, strategic frameworks, speculative creative, financial models and increasingly elaborate demonstrations of "how we think".

And after all that, clients are supposed to believe that a few hours in a conference room provides a reliable prediction of what the next five years of the relationship will look like.

It doesn't. It tells you who rehearses their pitch the most. In some cases it’s the best piece of work and the most effort that ever goes into the relationship, much like a job interview (I said in some cases).

And advertising agencies are exceptionally good at pitching.

PepsiCo appears to have done something altogether more radical.

It looked at what it wanted to build and found the organisation it believed could build it.

No tap dancing, no beauty parade required.

That is potentially a much more important development than who won the account.

The real show is the changing agency proposition

This is where the Coke and Pepsi story connects to the much bigger disruption facing the holding companies.

Both Coca-Cola and PepsiCo are increasingly looking beyond traditional media buying.

They want it all. Data. Technology. Identity. Automation. AI. Integration. Speed. Measurement. Operational efficiency. In other words, they increasingly want something that looks less like an advertising agency and more like a marketing operating system.

And yet the industry continues to buy and sell those capabilities through a process inherited from a very different era.

That contradiction is becoming harder to ignore.

The competitive advantage is no longer simply having the cleverest strategists, the hottest creatives, the biggest media buying operation or the most Titanium Lions.

It is increasingly about how effectively an organisation can get work from idea to execution time after time after time.

How quickly can it move? How much unnecessary friction sits between functional teams? How much technology is genuinely fit for purpose and integrated rather than generalist and bolted on?

How much data can actually be used? How much human effort is being wasted making the machinery work?

And, increasingly, how intelligently can AI be used without handing the keys over to the bloody thing?

That is a very different agency proposition.

So who actually got this wrong?

IMO nobody.

Publicis made a rational commercial decision.

PepsiCo made a bold procurement decision.

WPP remains a formidable competitor navigating a difficult transformation.

Coca-Cola has every right to reconsider whether an agency simultaneously serving its biggest competitor is compatible with its ambitions.

Omnicom has lost a huge global media relationship after more than 20 years, which is obviously sub optional for them.

The interesting question isn't therefore who screwed up?

It is why the industry has created a system in which these decisions are still surprising.

The holding companies have spent decades telling clients that scale creates advantage.

That they can manage complexity.

That they can put the right people in the right boxes.

That conflicts can be managed.

That vertical integration is the answer.

And perhaps all of that was true once.

Until their clients start wanting something fundamentally different.

Coke versus Pepsi is the punchline

The real story is not that Publicis chose Pepsi over Coke. The real story is that a $1.7 billion-plus global media decision can now happen without a traditional pitch, while one of the world's most established agency relationships is being forced to defend its relevance in an environment where technology, data and AI are rapidly changing what "agency" actually means.

That should concern everyone in Adland.

Because this scenario will trickle down and the next generation of client CMO’s and procurement may not care one iota about which holding company owns which agency and who they do work for.

They will care about whether the organisation can help them move faster, operate smarter and produce better work.

They may not necessarily even want another agency.

They may want infrastructure, intelligence, a better operating model.

And they may increasingly expect the technology underneath the agency relationship to be as sophisticated as the strategy sitting on top of it.

Which brings us neatly back to Coke and Pepsi.

Two giant brands. Two giant marketing machines. Two enormous agency relationships.

And one rather unfortunate reminder that when you promise clients you can be everything to everyone, eventually someone is going to ask whose warpaint you're wearing.

Now dim the lights, pass the popcorn, and make mine a Dr. Pepper.

Apparently, category conflict is as stressful as it is entertaining.
