Short answer: Marketing in 2026 is growing fastest where spend can be tied to outcomes: social, connected TV, commerce media, creator partnerships and programmatic buying. AI has become a meaningful budget item, but most organizations still lack the data, workflows and governance to scale it. Measurement across digital and traditional media remains the central constraint.

Which advertising channels are growing fastest in 2026?

IAB’s outlook puts social, connected TV and commerce media ahead of overall advertising growth. The common thread is not simply audience size; it is the ability to connect inventory with targeting, conversion signals or transaction data. Linear television remains under pressure as budgets move toward addressable and digitally measured formats.

Social advertising

Social is forecast to be the fastest-growing major U.S. channel in the IAB outlook. Growth includes short-form video, creator-led placements and increasingly automated buying. Treat the forecast as a market-growth signal, not a promise that every social campaign will produce positive return on ad spend. Results still depend on creative volume, audience quality, frequency control and a measurement approach that accounts for assisted conversions.

Connected TV

Connected TV combines television-scale video with digital distribution and, in some environments, household-level targeting. Its 2026 forecast growth reflects continued movement away from exclusively linear schedules. Before shifting budget, confirm whether a provider can provide deduplicated reach, frequency reporting, completion data and a credible way to test incremental outcomes.

Commerce media

Commerce-media networks use retailer or marketplace audiences and purchase data close to the point of sale. Their appeal is the short path from exposure to transaction, but reported return can be inflated when a network receives credit for customers who were already going to buy. Compare networks using incremental sales, new-customer share, margin and data-access terms rather than attributed revenue alone.

Programmatic buying

Programmatic represents automated buying across digital inventory and is already a large U.S. revenue category. Automation improves speed and targeting, but it also increases the importance of supply-path controls, invalid-traffic detection, privacy compliance, contextual suitability and transparent fees.

How AI is changing marketing budgets and operations

AI has moved from an experimental line item to an operating capability. Gartner reports that marketers allocate an average 15.3% of their budgets to AI, while only 30% describe their organization as mature or fully developed in AI readiness. In a separate Gartner finding, 70% identify AI leadership as a critical goal. These measures describe priority and capability, not a guaranteed productivity gain.

What the readiness gap means

Most organizations are funding tools before they have redesigned the processes around them. Gartner reports that 70% say internal processes are not mature enough to scale AI. Common blockers include fragmented customer data, unclear ownership, weak approval controls, incompatible systems and no agreed definition of acceptable model output.

Where AI budgets are most defensible

  • Content operations: briefing, variant production, translation and accessibility work with human editorial approval.
  • Audience and media analysis: segmentation, anomaly detection, forecasting and budget scenarios using governed first-party data.
  • Customer service and lifecycle marketing: response drafting, routing and next-best-action recommendations with escalation for sensitive cases.
  • Measurement support: taxonomy checks, data-quality monitoring and experiment analysis, without allowing a model to replace causal testing.

Evaluate an AI investment on data governance, workflow integration, human review, security, vendor portability and measurable lift. IAB Vice President Chris Bruderle described AI as “the connective tissue that links media, measurement, creative, and customer experience,” a useful test for whether a proposal improves the whole operating system rather than adding another isolated tool.

Additional signal from Germany

A 2026 Bitkom survey of German businesses found that 84% regard AI as the most important influence on marketing and 76% expect marketing automation to become more important. These are expectations from a national survey, not a global performance benchmark; use them to gauge direction of travel rather than to set a universal budget target.

Creator, social-video and retail-media trends across regions

Creator advertising is a substantial U.S. channel, while European data shows especially rapid expansion in social and retail media. The markets are not directly interchangeable: currency, regulation, platform availability, retail concentration and measurement conventions differ.

European segment 2025 value Year-over-year change What to examine before investing
Total digital advertising €131 billion 10.5% Country mix, format definitions and market coverage
Digital video €34.0 billion Not stated Completion quality, reach duplication and brand suitability
Social advertising €35.5 billion 19.2% Creator quality, audience context, frequency and disclosure
Retail media €13.3 billion 16.7% Incremental sales, new-customer rate, margin and data rights

For creator partnerships, assess more than follower count. Check audience relevance, view quality, disclosure compliance, rights to reuse content, exclusivity, brand-safety controls and whether sales or attention can be measured beyond a platform’s last-click report. For retail media, ask whether the network can separate genuine incremental demand from purchases that would have occurred without the ad.

Why measurement is the biggest marketing bottleneck

Nielsen found that only 32% of global marketers measure digital and traditional media holistically. Without a common view, teams can optimize each platform’s reported performance while losing sight of total reach, duplicated exposure, marginal cost and business impact.

Build a measurement foundation

  • Use one campaign taxonomy across paid, owned and earned activity.
  • Maintain reliable first-party identifiers and document consent, retention and permitted uses.
  • Define the business outcome first: incremental revenue, qualified pipeline, retention, profit or another agreed measure.
  • Combine methods: platform reporting for operations, experiments or geo tests for incrementality, and modeled analysis where direct observation is impossible.
  • Report reach and frequency across channels where deduplication is available; label modeled or estimated values clearly.

Do not compare a platform’s attributed conversions with another channel’s incremental conversions as if they were the same unit. A credible dashboard explains the attribution window, identity method, exclusions, confidence limits and the decisions the metric is intended to support.

How to prioritize channels for a 2026 plan

Use the following framework when comparing two or more channels. Growth rate alone should never decide the allocation.

Decision dimension Questions to answer
Audience and geography Does the channel reach the required customers in the markets where you can serve them?
Objective Is the job awareness, acquisition, conversion, retention or a combination?
Incremental outcome What result is additional exposure expected to create, and how will it be tested?
Inventory and format Will the campaign use search, social, video, creator content, commerce placements or another format?
Measurement reliability Can you observe, deduplicate or experimentally estimate the result?
Data and AI requirements What first-party data, permissions, integrations and human controls are needed?
Operational maturity Can the team produce creative, manage frequency and act on results quickly enough?
Privacy and brand safety Are consent, suitability, disclosure, supply-chain and platform-governance risks acceptable?
Economics What are the fully loaded costs, contribution margin, payback period and opportunity cost?

What marketers are using, according to HubSpot’s 2026 survey

HubSpot’s 2026 survey identifies website, blog and SEO, organic social and email among the most leveraged channels. It also reports that 38% of respondents plan to increase investment in AI chatbots, while video and paid social each reach 37% in the survey’s investment signals.

These findings are directional rather than universal ROI benchmarks. HubSpot’s sample and methodology differ from the industry-revenue and executive-survey methods used by IAB, Gartner and Nielsen. A channel’s popularity in a survey does not establish that it is the best choice for your audience, business model or margin structure.

A practical 2026 marketing planning checklist

  1. Set one primary business outcome. Choose the revenue, profit, pipeline, retention or awareness measure that will govern the plan.
  2. Audit the baseline. Document current spend, reach, frequency, conversion definitions, attribution windows, data quality and fully loaded production costs.
  3. Assign channel roles. Specify which channels create demand, capture intent, close sales or retain customers; avoid giving every channel the same job.
  4. Reserve test budget. Fund geo tests, holdouts, creative experiments or other designs that can estimate incrementality before scaling a forecast.
  5. Set AI controls before deployment. Define approved data, model-risk reviews, human sign-off, logging, access rights and a rollback process.
  6. Review on a fixed cadence. Reallocate using marginal outcomes and quality-adjusted reach, not only platform-reported conversions or headline growth.

How to interpret 2026 marketing statistics responsibly

  • Separate actuals from forecasts. A reported 2025 revenue figure and a 2026 growth projection answer different questions.
  • Keep geography attached. U.S. advertising, European advertising and a German business survey cannot be combined into one global rate.
  • Distinguish market size from performance. A large or fast-growing channel can still be inefficient for a particular customer segment.
  • Check definitions. “Creator advertising,” “retail media,” “digital video” and “AI readiness” can be defined differently across studies.
  • Read survey percentages as signals. Intentions and self-assessments are not audited spend, causal lift or profitability.

Bottom line for 2026

Prioritize channels that match your objective and can demonstrate incremental business value. Social, connected TV, commerce media, creators and programmatic buying are attracting the strongest growth signals, while AI deserves investment only when data, governance and workflows can support it. The durable advantage is not choosing the trendiest channel; it is building a measurement and operating system that lets you scale what actually works.
