Programmatic and Data-Driven Advertising: Industry Report

Summary

Programmatic and data-driven advertising is the automated buying and selling of digital audiences and inventory through demand-side platforms, supply-side platforms and ad exchanges. The latest available data show strong growth. US programmatic advertising revenue reached $162.4 billion in the latest full-year period, up 20.5% ². A compiled global forecast puts programmatic spend at $725 billion, an 18% increase, and estimates that programmatic accounts for 91.5% of worldwide digital display spending ¹. These figures come from different scopes and methods, and the source set contains no audited global total. The main constraints are media quality: fraud, brand safety, viewability and transparency are the biggest barrier to growth for 52% of European respondents ³. Buyers want more proof of performance and easier integrations ⁵. Privacy direction is unsettled: Google retired a large set of Privacy Sandbox APIs but keeps third-party cookies supported in Chrome ⁹¹⁰. AI use is high, with 86% of 50 European respondents using AI for marketing ⁴, yet buyers do not agree on the role of agentic AI ⁵. Outlook: growth is likely to continue, with more automation, pressure for transparent measurement and changing agency and platform relationships. The source set has no verified CPM, CPC, CAC, ROAS or attribution-window benchmarks.

Key findings

1. 1

   US programmatic revenue is large and still growing fast

   Programmatic advertising revenue in the United States reached $162.4 billion in the latest full-year period, a rise of $27.6 billion and 20.5% year over year, up from 18.0% in the prior comparison ².

   Confidence: High
2. 2

   Programmatic dominates digital display, but global size is uncertain

   A compiled forecast gives a global programmatic market of $725 billion, an 18% increase, and an estimated 91.5% share of worldwide digital display spending ¹. The figure is a secondary compilation, and independent global totals vary widely by scope and method.

   Confidence: Medium
3. 3

   Media quality is the main barrier to growth in Europe

   52% of European respondents cite fraud, brand safety, viewability and transparency as the biggest barrier to growth ³. Only 17% activate the majority of their campaigns across channels ³.

   Confidence: High
4. 4

   Buyers want proof of performance and easier integration

   More than four in ten US buyers want more proof of performance and easier integrations with platforms and demand-side platforms ⁵. The exact share is not given in the source.

   Confidence: Medium
5. 5

   Third-party cookie policy is changing without a single replacement

   Google retired a large set of Privacy Sandbox APIs and ended its push for a single Chrome-led replacement for third-party cookies, and it will not add a user-facing cookie choice prompt, so cookies remain supported ⁹¹⁰.

   Confidence: Medium
6. 6

   AI is widely used but its buying role is unsettled

   86% of 50 respondents in a European study use AI for marketing, while agentic buying and selling ranked lower at 38% among 29 respondents asked about advertising workflows ⁴. US buyers agree there is a role for agentic AI in programmatic, but there is no consensus on that role ⁵.

   Confidence: Qualitative

1Industry definition and scope

This report covers programmatic and data-driven advertising: the buying, selling and optimizing of digital advertising through automated systems that use audience data and auction mechanisms. Geographic scope is global, with United States and European sub-scopes used only where a source is regional or national. The reporting period is the latest available data and recent forecasts. Sources do not share one calendar period, so figures are compared only with their stated context.

Terminology needs care. Sources report different measures: S1 reports forecast spend, S2 reports revenue, and S8 reports display and connected TV (CTV) revenue or estimates ¹²⁸. These are not interchangeable. Segments covered are display, video, CTV and digital audio. Retail media and programmatic digital out-of-home figures appear only in unverified compilations and are excluded.

Metrics used in this report are defined for interpretation. Cost per thousand impressions (CPM) is the cost of 1,000 ad impressions. Cost per click (CPC) is the cost of each click. Customer acquisition cost (CAC) is the spend needed to win one customer. Return on ad spend (ROAS) is revenue attributed to advertising divided by ad spend. Conversion rate is the share of exposed or clicking users who complete a target action. Brand lift is the change in brand metrics such as awareness or consideration among exposed versus control audiences. Attribution windows are the periods after exposure within which a conversion is credited, and they vary by platform. The source set contains no verified benchmarks for these metrics.

Definitions are standard industry usage stated by the report writer, not sourced facts.

2Market size, structure and value chain

Market size estimates differ widely. A compiled forecast gives $725 billion for global programmatic spend and an 18% increase, and the compilation attributes the underlying estimate to eMarketer ¹. The source set also notes that published global estimates vary widely with scope and method, and that no audited global total was retrieved. For the United States, programmatic revenue of $162.4 billion is an observed industry-association figure ². Display advertising revenue reached $81.6 billion, up 9.8% ⁸. The table below sets out the indicators by source and type. Rows should not be added together because they measure different things.

Writer's interpretation, not a sourced fact: the value chain runs from advertisers and agencies, through demand-side platforms that buy inventory, supply-side platforms that sell it for publishers, and ad exchanges that run auctions, to publishers and their audiences. Data providers and measurement partners sit across these steps. Revenue models include auction-based pricing, typically priced per thousand impressions, and fees charged by intermediaries. The pack does not quantify fee shares or the split of value among these stakeholders, so that structure is not measured here.

• US programmatic advertising revenue, latest full year 162.4US dollars billion Observed United States, Latest full-year period [2]

Value chain roles are the writer's interpretation. No sourced value chain share data was retrieved.

3Customers, demand and adoption

Customers are brand advertisers, agencies acting for them and, on the supply side, publishers. Demand is growing in the connected TV and video channels. The latest survey shows that programmatic maturity is strongest in display at 30% and video at 28%, while CTV and digital audio show more uncertainty among European respondents ³. Only 17% of respondents activate the majority of their campaigns across channels, which points to fragmented practice ³.

Purchasing criteria are shifting toward proof and control. More than four in ten US buyers want more proof of performance and easier integrations with platforms and demand-side platforms ⁵. In a survey of more than 200 brand and agency buyers, five of the six top advertiser focus areas for the period are tied to AI ⁷. Media quality remains a central concern, as discussed in the next sections.

Audience behavior and consumer attitudes are not covered by a verified source in this pack, so no claims are made about consumer engagement or attention. Privacy and consent expectations are shaped by browser and platform decisions described in the regulation section. Data gap: no verified CPM, CPC, conversion rate, CAC, ROAS or brand lift figures were retrieved, so demand cannot be measured in those terms here.

• Respondents who activate most campaigns across channels 17percent of respondents Observed Europe, Latest survey period [3]

Survey results are from industry-association studies and reflect respondent samples, not whole markets.

4Competitive landscape and key players

The market includes several provider types: demand-side platforms used by buyers, supply-side platforms used by sellers, ad exchanges, agencies, publishers, data providers and measurement partners. The source set does not profile individual demand-side platforms, supply-side platforms or publishers, and no filings from Amazon, Meta or The Trade Desk were retrieved. Their business models and market shares are therefore not compared here.

Google is the one named platform with primary evidence in the pack. Its Privacy Sandbox publications show that it retired a large set of Privacy Sandbox APIs and ended its push for a single Chrome-led replacement for third-party cookies ⁹¹⁰. Its browser decision keeps existing cookie-based tools supported, which affects how other providers can target audiences. The pack does not measure Google's share of programmatic spend, and platform concentration figures appear only in unverified compilations, so concentration cannot be quantified.

Competitive pressure comes from two directions: buyers demanding proof and integration ⁵, and AI tools that change workflows ⁷. Differentiation is therefore likely to rest on measurement transparency, integration quality and governance of automated buying, though the pack provides no direct performance comparison between providers. Sources are limited to one platform case and industry-association research, so the comparison is incomplete.

Comparable provider examples were limited in the source pack.

5Technology, operations and workforce

AI is the most visible technology shift. In a European study, 86% of 50 respondents use AI for marketing, while agentic buying and selling ranked lower at 38% among 29 respondents asked about advertising workflows ⁴. These samples are small, so the findings indicate direction rather than market-wide rates. US buyers agree there is a role for agentic AI in programmatic, but there is no consensus on that role ⁵. Operating practice is therefore moving faster than agreed standards for how AI should act on a buyer's behalf.

Operational priorities follow from buyer demands. Buyers want proof of performance and integrations that work across platforms ⁵. Five of the six top advertiser focus areas for the period are tied to AI ⁷. The pack does not provide productivity measures, cost savings or error rates from automated buying, so efficiency claims cannot be verified.

Workforce data is not covered by a verified source. Writer's interpretation, not a sourced fact: professionals in this field are likely to need skills in data analysis, platform and vendor management, measurement design and AI governance. No skills shortage, talent supply or salary data was found in the pack, so these needs are not quantified.

• Survey respondents using AI for marketing 86percent of respondents (50 respondents) Observed Europe, Latest survey period [4]

Workforce and skills conclusions are interpretation, not sourced findings.

6Regulation, standards, risk and sustainability

The source pack contains no statute, regulator publication or binding rule on programmatic advertising, so no binding legal requirement is reported here. Practitioners should check the rules in their own jurisdiction. Privacy developments reported in the pack are browser and platform decisions rather than laws: Google retired Privacy Sandbox APIs and will keep third-party cookies supported in Chrome without a user-facing choice prompt ⁹¹⁰. These are company policies, not regulation, and they may change again.

Brand safety, fraud and viewability are the main quality risks. 52% of European respondents cite these issues and transparency as the biggest barrier to growth ³. The pack does not include verified fraud or brand safety rates, and reports from specialist verification providers were referenced only indirectly. Measurement standards from industry bodies on attribution windows and view-through conversion were not retrieved, so this report cannot state a standard.

Ethics and governance of AI are a rising risk. A news report titled around whether AI is changing programmatic buying faster than control over it notes that control lags adoption ⁴. Sustainability and environmental factors are not covered by a verified source in the pack, so no claims are made. Operational risks include dependence on a few platforms, opaque automated decisions and inconsistent definitions of spend, revenue and reach.

Risk discussion combines sourced survey findings with the writer's interpretation.

7Challenges, opportunities and case examples

The main constraint is trust in media quality. Fraud, brand safety, viewability and transparency concern 52% of European respondents ³. Buyers want stronger proof of performance and easier integration ⁵. Fragmented activation, with only 17% running most campaigns across channels, limits the benefit of automation ³.

Opportunities are concentrated in CTV and video. A global forecast puts programmatic CTV spend at $42 billion, a 38% increase ¹. IAB estimates US connected TV ad spend at $29.3 billion, up 11% from the prior estimate ⁸. Estimates differ by scope, so these are growth signals rather than a single market size. AI is a leading buyer priority ⁷, which creates demand for tools that improve planning and measurement, though buyer consensus on agentic roles is still missing ⁵.

Case example one is Google's Privacy Sandbox. Google retired a large set of Privacy Sandbox APIs and dropped its push for a single Chrome-led replacement for third-party cookies ⁹¹⁰. For advertisers and ad-tech providers, this means cookie-based targeting remains available in Chrome, but the pack does not measure the effect on campaign results. Case example two is the IAB buyer research: buyers across the US want proof of performance and integrations ⁵. Comparable examples were limited: the pack contains no primary filings or case results from Amazon, Meta, The Trade Desk or publishers.

Comparable company examples were limited to Google and industry-association research.

8Outlook and strategic implications

The near-term outlook is growth. Programmatic revenue in the United States rose 20.5% in the latest full-year period ², and US ad spend is projected to grow 9.5%, with digital growing faster than the wider market ⁷. Forecasts for global programmatic spend and CTV are higher still ¹. These are forecasts and industry estimates, so they carry uncertainty about scope and method.

Medium-term uncertainty centers on privacy and AI. Cookie-based targeting remains supported in Chrome, but the long-term path is not settled ⁹¹⁰. AI will change workflows, but agreement on the role of agentic buying is absent ⁵. Scenarios: in a continued-growth case, automation and CTV expand while buyers demand proof; in a constrained case, quality problems and fragmented activation slow adoption. The pack does not quantify either scenario.

Implications for stakeholders: advertisers should set proof-of-performance requirements and test integrations before scaling automation; agencies should build governance and measurement skills and clarify how AI-driven buying is supervised; platforms and ad-tech providers should improve integration and transparency; publishers should watch quality metrics and CTV demand. Measurement providers should document attribution windows and methods. Regulators should consider the privacy shift as a platform policy matter for now, and no binding rules are identified here.

Outlook combines forecasts from industry sources with the writer's interpretation.

9Conclusion

Programmatic and data-driven advertising is large and growing, with the latest available figures showing strong US revenue growth ². The most defensible takeaways are that media quality and proof of performance limit growth ³⁵, that privacy direction is still changing ⁹¹⁰, and that AI adoption is ahead of agreed roles ⁴⁵. Global size estimates remain uncertain.
