The Inflection Point: Buy vs. Build Has Tipped

For years, the retail media race was framed as a contest of engineering might — who could build the next cross-retailer network fastest.
That calculus has now flipped.

The infrastructure required to compete — scaled identity graphs, closed-loop attribution, cross-retailer integrations — has grown too costly, too slow, and too politically fraught to recreate from scratch.

Criteo has already done it:

• 235 retailers
• 4,100 brands
• Over a decade of refinement

The market’s unspoken truth: the buy-vs-build era is over.
This isn’t a race of innovation — it’s a race of acquisition.
And Criteo just declared itself in play.

The Strategic Readout: A Market Ready to Collapse Inward

Retail media is entering its Great Consolidation phase — the same cycle that crushed the once-vast field of independent DSPs a decade ago.
Back then, it was the rise of walled gardens and closed ecosystems that suffocated openness.
Now, it’s the gravitational pull of retail-first platforms — Walmart, Amazon, Target, Instacart — each building their own ad empires.

For any company that’s not yet in the game, acquiring Criteo is no longer optional; it’s existential.
To buy Criteo is to fast-forward a decade — to acquire not just infrastructure, but legitimacy.

Who’s on the hunt?

• Tech titans like Microsoft or Salesforce, seeking an instant retail media foothold.
  They need Criteo’s decade-old graph and retailer relationships to immediately compete with Amazon's data moat.
• Agency holding groups like Omnicom or Publicis, desperate to own tech rather than rent it.
  Controlling the core ad-serving technology is crucial for providing differentiating value to their brand clients.
• Retailers like Kroger or Best Buy, eager to expand their ecosystems before the window closes.
  By leveraging Criteo’s existing network, they can accelerate their own RMN growth outside their immediate store footprints.

Each has motive.
Now, they have opportunity.

The Macro Signal: From Gold Rush to Land Grab

Criteo’s maneuver marks the end of retail media’s gold rush phase.

But as the market matures, fragmentation becomes friction.
Dozens of RMNs competing for limited attention have left brands overwhelmed, measurement muddled, and margins thin.
The next phase is not proliferation — it’s platformization.

Criteo’s move to Luxembourg is the canary in this coal mine.
The era of independent middle-layer ad tech — those nimble connectors between brands and retailers — is ending.
Scale now trumps agility.
Capital now dictates capability.

The Financial Catalyst: Strong Q3, Stronger Intent

Criteo’s Q3 2025 results quietly reinforced this narrative:

• 10% retail media revenue growth
• Healthy margin expansion
• Renewed investor confidence

But numbers alone weren’t the story — timing was.
By pairing robust earnings with the legal greenlight for acquisition, Criteo didn’t just report results; it set the stage.

The market heard it loud and clear:
“We are open for business.”

The MediaAMP POV: The Great Re-Platforming Has Begun

At MediaAMP, we see this as more than a single company’s pivot — it’s the opening act of the Consolidation Wars.
Every independent player is now forced to choose:

• Align or be acquired.
• Integrate or evaporate.

The buy-side, meanwhile, is shifting strategy.
Agencies are under pressure to prove value in a world where data advantage sits behind paywalls.
Retailers are realizing that the next wave of growth won’t come from “more networks” — but from fewer, better-integrated ones.

Criteo’s redomiciling is the first domino.
Expect others — The Trade Desk, Roku, even Instacart Ads — to reassess their global structures as M&A accelerates.

The Endgame: When Independence Becomes Inefficiency

This is not a story of failure, but one of adaptation.
The complexity of cross-retailer integration is demanding a unified approach, making independent middle-ware unsustainable.

Let’s be clear: this isn’t death.
It’s metamorphosis.
Independent ad tech will not vanish — it will be absorbed.
What disappears is redundancy.

The new ecosystem will look like this:

• A handful of global retail media giants — omnichannel, interoperable, and data-rich.
• A layer of transparent measurement alliances, likely enforced by IAB or joint governance bodies.
• And a small but potent cluster of API-first connectors, focused on standardization, not scale.

Criteo, in that world, becomes the nucleus — the platform every acquirer wishes they’d built, but now simply must buy.

The Bottom Line: A Signal Disguised as a Legal Filing

Sometimes the loudest corporate moves whisper.
Criteo’s relocation wasn’t a press stunt — it was a prelude.

It tells us the market has matured past experimentation.
It tells us that independence is now inefficiency.
It tells us that the last great independent retail media network is ready to be claimed.

The next headline won’t be about a move to Luxembourg.
It will be about who writes the check — and how that single transaction reshapes the architecture of retail media itself.

The table is set. The chips are down.

The Great Consolidation has begun.
