No: there is no universal expiration date for either the chief data officer (CDO) or chief AI officer (CAIO). As AI becomes part of everyday business, their responsibilities may shift, overlap or be combined—but whether to keep separate leaders depends on the organization’s needs, decision rights and capacity.
Why the roles can look redundant
AI depends on data, so decisions about data quality, access, governance and risk increasingly intersect with AI strategy and deployment. That overlap can make it unclear who owns a use case, approves its data, or manages its risks.
The trend is visible in federal organizations. AI use rose from 67% in 2024 to 78% in 2025, according to the Data Foundation and Deloitte’s 2026 Federal CDO Survey. The same survey found that 30% of federal CDOs also served as CAIOs, 96% collaborated with AI leadership at least monthly, and 64% were very or completely involved in setting data-governance policies for AI use. These are federal survey findings, not estimates for all businesses. Data Foundation and Deloitte, 2026 Federal CDO Survey
Gartner reported in 2025 that 70% of chief data and analytics officers (CDAOs) had primary responsibility for building AI strategy and the operating model; 36% reported to the CEO. That suggests AI leadership is already part of many data leaders’ remit, though the figures do not establish that the roles are interchangeable. Gartner, 2025

Overlap is not the same as duplication. In the 2024 Federal CDO Survey, nearly half of CDOs cited conflicting statutory or legal authorities. Half viewed CAIO missions as highly complementary, while some reported potential redundancy. Data Foundation, 2024 Federal CDO Survey
What a CDO and a CAIO are meant to own
In federal guidance, the CDO is responsible for data strategy and assets; the CAIO coordinates AI use, innovation and risk. The Department of State describes the CAIO’s primary role as “coordination, innovation, and risk management” for an agency’s AI use, “as opposed to data or IT issues in general.” Its own Chief Data and AI Officer performs both the CAIO and CDO roles.

This distinction is useful beyond government as an organizational-design principle, but it is not a universal job description for private companies. One leader can hold both titles; the important question is whether the organization has clear accountability for the work.
Four models companies can choose
Keep the CDO and CAIO separate
This can suit an organization where data governance and AI deployment are each substantial responsibilities. It preserves dedicated attention, but requires written decision rights: who approves data policy, who authorizes AI use cases, and who handles risk exceptions and disputes.

A combined chief data and AI officer can provide one accountable owner for the path from data to AI outcomes. The trade-off is capacity: governance, risk oversight and delivery can compete for one executive’s time, creating bottlenecks or blurred priorities.
Expand the CDO role into AI enablement
Where the data foundation is mature and AI adoption is the main constraint, the CDO’s remit may shift toward enabling AI use. The organization still needs to assign responsibility for AI-specific risk and deployment decisions rather than assuming those duties follow automatically from the title.
Rank #4
Keep the CAIO as a coordinating role
This can work when experimentation is broad but technology delivery remains with the CIO and data stewardship remains with the CDO. Coordination only works if the CAIO can bring the right owners together and has a clear route to escalate unresolved decisions.
How to decide whether to combine the jobs
Compare the models against the organization’s actual workload and accountability needs, rather than choosing a title because it is becoming more common.

- Helpful in various ways
| Decision area | Separate CDO and CAIO | Combined CDAO or equivalent |
|---|---|---|
| Decision rights | Assign authority between leaders for data policy, AI use cases and risk exceptions; document escalation. | One executive can own the full chain, with explicit authority and review processes. |
| Scope | Dedicated leaders can focus on enterprise data stewardship and AI strategy or deployment respectively. | One leader spans data assets and AI strategy, governance and delivery. |
| Accountability | Define separate owners for data quality and trust, and AI safety and compliance. | One executive is accountable for both domains; supporting teams still need defined responsibilities. |
| Capacity | More dedicated leadership capacity, with coordination overhead and possible disputes. | Fewer handoffs, but a risk of overload or delayed decisions if the remit is too broad. |
| Reporting line | Set reporting lines that give both leaders access to the executives needed to resolve conflicts. | Choose a line—such as CEO, COO or CIO—that matches the combined remit and authority. |
| Outcomes | Measure data trust and governance alongside AI-related mission, revenue, productivity or risk outcomes. | Measure whether joined-up ownership improves those outcomes without weakening either function. |
There is no single best structure. A company should first identify where decisions currently stall or fall between teams, then define who has authority to make each decision and who is accountable for results. If both functions have sustained workloads, separate leaders may be warranted; if the key problem is fragmented ownership and one executive can realistically cover the scope, a combined role may make sense.

KPMG’s 2025 analysis argues that as data and AI boundaries blur, CDO responsibilities may evolve into or merge with those of a Chief AI Officer to reduce fragmentation and misalignment. That is a forecast about organizational design, not a legal requirement or timetable. KPMG, 2025
The federal Evidence Act framework established the CDO function, and the CDO Council’s 2025 survey lists the CAIO among adjacent enterprise leadership roles. The cited guidance and surveys do not establish a universal statutory sunset date, fixed tenure or mandatory replacement schedule for either title. For a company, the practical issue is whether the current structure delivers clear ownership and results as AI use expands.
