Our Take
Strong media volume masks deeper structural problems: two major client losses and a 32% drop in retail media revenue suggest platform dependency risks.
Why it matters
Retail media networks face consolidation pressure as platforms like Roundel and Uber Eats reduce third-party dependencies. Ad buyers need contingency plans for vendor concentration risk.

Media buyers: audit your retail media spend concentration across vendors this week so you can identify backup channels before Q2 planning.
Criteo crosses $1B media spend despite revenue decline
Criteo processed $1 billion in media spend during Q1 2026, marking the first time the ad tech company crossed that threshold in a first quarter (company-reported). The 8% year-over-year increase, adjusted for inflation, came as total revenue dropped 9% to $425 million compared to $451 million in Q1 2025.
The revenue decline stems partly from a 32% year-over-year drop in retail media revenue, minus traffic acquisition costs (company-reported). Criteo attributed this decline to changes in relationships with Roundel and Uber Eats, first announced a year ago.
The company acknowledged that growth numbers remain affected by two major client losses, though it did not specify which clients or the timeline for these departures.
Platform consolidation squeezes third-party ad tech
The disconnect between growing media volume and shrinking revenue signals a structural shift in retail media. Platforms like Target's Roundel and Uber Eats are pulling advertising capabilities in-house rather than relying on third-party tech providers.
This consolidation trend puts mid-tier ad tech companies in a bind: they can process more media spend but capture less revenue per dollar as clients negotiate better terms or move operations internal. The 32% retail media revenue drop specifically points to reduced take rates or lost business in Criteo's fastest-growing segment.
For advertisers, this creates both opportunity and risk. Lower take rates mean more media budget reaches actual advertising, but fewer independent platforms reduces negotiating leverage and backup options.
Diversify retail media vendor exposure
Media buyers should audit current retail media spend concentration across vendors. If more than 40% of retail media budget flows through a single platform or tech provider, develop relationships with alternative channels now before they reach capacity constraints.
Procurement teams should negotiate contract terms that include migration support and data portability clauses. Criteo's client losses demonstrate how quickly large accounts can shift, leaving advertisers scrambling for replacement inventory.
For Q2 planning, allocate 15-20% of retail media budget to test alternative platforms or direct relationships with retailers. The current consolidation creates pricing pressure that benefits buyers willing to diversify.
