Coca-Cola’s North American media shift gives Omnicom a large account and a clear test of its buying power. For the advertiser, the commercial question is whether that scale can improve media returns as spending moves toward social channels.
Omnicom has secured the U.S. and Canada assignment, say two people familiar with the agreement. Coca-Cola has more to do than replace an agency: it needs the promised savings and new tools to improve campaign performance.
Social Spending Changes the Value of Agency Scale
Last year, Coke CMO Manolo Arroyo said social advertising and creator content accounted for 70% of its media spending. TV had received 75% of the budget six years earlier.
With spending shifting, marketers need to rethink how they assess agency value. Reach still has a place in negotiations, but social budgets require content decisions and paid distribution to work closely together. For acquisition teams, the test is whether those links help move consumers toward a purchase.
Omnicom brings substantial buying weight. Following its absorption of IPG, its billings total $75.6 billion, representing roughly 31% of billings managed by global marketing services groups. With that buying volume, it has leverage in negotiations with media sellers, including social platforms.
Buying leverage doesn’t, by itself, demonstrate a return on investment. Coca-Cola should judge better buying terms against its campaign goals; lower media costs alone aren’t sufficient proof.
Even a cheap impression offers little value when the audience is wrong or the creative is weak. To put the agency’s buying strength to use, the content still needs to give consumers a reason to act.
A Dedicated Team Needs a Measurable Brief
One person familiar with the discussions said Omnicom promised Coca-Cola a purpose-built team rather than personnel carried over from PepsiCo. The pitch also included senior staff, cost savings and technology improvements.
An advertiser wants to know what it will get after an account change, so those commitments address a reasonable concern. A dedicated team can give the relationship focus, but the staffing promises need to spell out responsibilities.
Coca-Cola should turn those promises into an operating brief the team can use:
- Assign responsibility for budget decisions and campaign results across the account.
- Define savings against an agreed baseline, with media quality kept in view.
- Require each proposed technology change to solve a specific buying or measurement problem.
- Set a review process that connects creative choices with paid-media results.
These are recommended controls, not reported terms of the agreement. They would help distinguish a persuasive agency pitch from an operating model that supports growth.
Work is due to begin Dec. 1. The handover needs to establish decision ownership and measurement rules before the team makes changes to campaign execution.
Account Size Is Not Evidence of Marketing Returns
The financial scale explains why this win matters to Omnicom. It does not tell Coca-Cola how well the new arrangement will perform.
COMvergence estimates place Coca-Cola’s annual U.S. and Canada media spending at $785 million. Its estimate for PepsiCo’s North American spending is roughly $780 million. On that regional comparison, the incoming business nearly matches the account Omnicom lost.
The global comparison is different. COMvergence puts the PepsiCo media billings previously handled by Omnicom at about $1.1 billion. Coca-Cola’s North American assignment therefore replaces much of that volume, without covering the full amount.
For the client, these figures describe account scale rather than campaign effectiveness. A performance review needs a separate set of questions.
| Buying question | Growth question |
|---|---|
| Did negotiated media costs fall? | Did the savings improve results against the campaign goal? |
| Did the plan secure more reach? | Did that reach include consumers the brand intended to influence? |
| Did new tools speed up execution? | Did faster decisions improve campaign performance? |
The distinction keeps procurement gains in context. Savings can support growth, but they should be assessed alongside the quality of demand created.
Regional Buying Needs Shared Measurement Rules
Coca-Cola’s agency arrangements still span several groups. WPP retains its global responsibilities except in Japan and South Korea, where Dentsu remains responsible. Mediasense managed the review.
That structure makes the North American handover a coordination task as well as a buying task. Regional teams may need different channel plans, while the advertiser needs results it can interpret across markets.
Coca-Cola should agree on common definitions for campaign goals and reported outcomes wherever comparisons are useful. Shared definitions would help prevent local reporting choices from obscuring whether a plan worked.
The aim should be consistent evaluation, with room for market-specific execution. Requiring identical tactics everywhere could weaken the value of local judgment.
Make the First Reviews About Business Outcomes
Omnicom’s win is commercially significant, especially after PepsiCo moved its account to Publicis. Coca-Cola’s priority should remain the performance of its own media investment.
The first reviews should examine whether promised savings preserved media quality and whether the new team improved campaign decisions. Social and creator spending also needs a clear account of how paid distribution supports the brand’s goals.
During the transition, Coca-Cola should set those expectations so they can guide subsequent budget choices. Agency scale then has a practical purpose: helping each campaign deliver more value, without becoming the main reason to approve it.
