The data clean room market is experiencing fragmentation due to agency acquisitions and the rise of cloud-based alternatives, forcing publishers to manage multiple environments. To maintain advertiser relationships, publishers are advised to prioritize technical agility and interoperability over deep expertise in every individual platform.
The immediate implication is that publishers can no longer dictate the terms of data collaboration; they must instead build flexible operating models that translate identity and governance across disparate silos. This shift moves DCRs from a one-off technical integration to a core operational capability where match rates and identity resolution vary by environment. Within the broader ecosystem, the move toward agency-owned 'supergraphs' is driving a wedge between neutral cloud providers and agency-locked tools. Watch for the adoption rate of IAB Tech Lab standards to determine if the industry can successfully consolidate these fragmented workflows or if publishers will be forced to maintain costly, bespoke connections for every major buyer.
The Publicis-LiveRamp and WPP-InfoSum acquisitions represent a structural shift in how data clean rooms are governed. Publicis Groupe completed its acquisition of LiveRamp in early 2025, integrating the identity and data collaboration platform into its CoreAI division, which raised immediate concerns among publishers about whether LiveRamp's previously neutral infrastructure would remain accessible to non-Publicis buyers. WPP's parallel move to acquire InfoSum followed a similar pattern, consolidating a privacy-focused clean room under an agency holding company and prompting questions about data portability and governance standards across the ecosystem.
The IAB Tech Lab has been working to address interoperability gaps that fragmentation creates. The Data Clean Room standards working group published updated specifications in 2025 aimed at establishing common measurement and identity resolution protocols across platforms, though adoption remains uneven. Cloud-native alternatives from AWS, Google, and Snowflake have gained traction as publishers seek vendor-neutral environments that are not subject to agency ownership conflicts. AWS Clean Rooms and Google BigQuery's analytics capabilities now compete directly with specialist tools like InfoSum and LiveRamp for publisher-advertiser data collaboration workflows.
C-Centric's positioning as an independent orchestration layer reflects the market's demand for cross-platform coordination. David Barker, C-Centric's founder, has argued that publishers need abstraction layers that can translate between disparate clean room environments rather than building point-to-point integrations, a view that aligns with broader industry movement toward interoperability standards. The fragmentation problem is compounded by the fact that each cloud provider and specialist vendor uses different identity resolution methods, match-rate thresholds, and governance policies, meaning a publisher working with five advertisers may need to maintain five distinct technical and compliance workflows simultaneously.
Data clean room fragmentation is increasing as agency acquisitions like Publicis-LiveRamp and WPP-InfoSum disrupt neutral data environments. This shift forces publishers to manage multiple, disparate workflows to maintain advertiser budgets. Consequently, media owners must prioritize technical agility and cloud-native solutions over mastering individual specialist tools to ensure effective data collaboration.
Publishers fear that acquisitions like Publicis-LiveRamp and WPP-InfoSum compromise the neutrality of these platforms, potentially limiting access or data portability for non-agency buyers.
Cloud-native platforms such as AWS Clean Rooms, Google BigQuery, Snowflake, and Microsoft Azure are emerging as vendor-neutral alternatives to specialist tools.
