B2B Content Marketing in 2026: 59% Rate It Effective
The Content Marketing Institute's 2026 B2B Benchmarks survey of 1,015 marketers finds 59% rate their content marketing somewhat or highly effective, while 95% now use AI-powered marketing applications and just 9% plan to grow human-resources investment in 2026. The channel still works at scale, but the budget split signals a structural reshuffle of how the work gets done.

What the report covers
The Content Marketing Institute (CMI) has run its annual B2B Content Marketing Benchmarks, Budgets, and Trends survey since 2010, in partnership with MarketingProfs. The 2026 outlook, released on 8 October 2025 with sponsorship from Storyblok, captures the state of B2B content marketing at a point where most of the practice is being recoded around AI. Fieldwork ran from 24 June to 14 August 2025, sampling 1,015 B2B marketers across in-house, agency and consulting roles, drawn predominantly from North America. The dataset is the most-cited single reference for B2B content marketing maturity, AI adoption, channel effectiveness and budget priorities in English-language B2B marketing.
Programme effectiveness has held steady at roughly six in ten marketers reporting their content marketing is somewhat or highly effective (12% highly effective, 47% somewhat effective), and 97% now operate from some form of documented or undocumented content strategy. Where 2026 diverges sharply from earlier editions is the AI distribution: 95% of respondents use AI-powered marketing applications in some part of their workflow, and 87% of those using AI for content creation report improved productivity. The B2B marketing story over the past decade has shifted from can content marketing work to how are teams running it now that AI does most of the drafting.
Three secondary readings sharpen the picture. Thought leadership is universal: 96% of respondents create thought leadership content, with LinkedIn cited by 76% as the single most effective distribution channel. First-party data collection is now table stakes at 91%, but only half of teams report governance maturity to act on it. And the 2026 budget plan inverts the historic pattern: 45% are increasing AI tool spend, 33% events and experiential, and just 9% plan to grow human-resources investment (salaries, training, headcount). Spend is moving toward platforms while the people who run the programmes get less of the increase.
What this means for UK marketers
For UK B2B marketers, three concrete reads come out of the 2026 benchmarks. First, the headline "content marketing generates three times as many leads" claim that circulated through digital-marketing handbooks for most of the 2010s was always thin on methodology. The current CMI data measures effectiveness differently and more credibly: roughly six in ten B2B marketers reporting that their programmes are somewhat or highly effective, with the strongest performers anchoring on documented strategy and clear measurement. UK B2B brands building a content marketing programme from scratch should treat 59% as the bar to clear rather than the floor to settle for, and read the 41% who rate themselves neutral or worse as the more honest cautionary signal.
Second, AI now runs through the production layer rather than sitting alongside it. With 95% of respondents using AI-powered marketing applications and 87% of content-creation users reporting productivity uplift, the operational question for UK teams has stopped being whether to adopt AI and become which steps to automate (research, outlining, first-draft, variant generation) and which to ringfence for human judgement (editorial standards, brand voice, factual verification, expert quotes). The 58% who say AI improves content quality and the 12% who say it decreases quality both have a point: teams using AI for variant generation and structured editing are seeing gains, while teams using it for unedited first-draft publication are degrading their output. The broader picture across the content marketing discipline matches this split, with editorial discipline becoming the differentiator rather than production volume.
Third, the budget split is the strongest single signal of where 2026 will go wrong for some teams. With 45% planning to increase AI tool spend and only 9% prioritising human resources, the implied bet is that platform leverage substitutes for senior editorial and strategic capacity. The CMI data on thought leadership (96% create it, but 37% report minimal employee participation) shows where this snaps: thought leadership only works when senior people contribute meaningfully, and AI cannot substitute for the named expertise LinkedIn audiences vet. UK B2B brands that hold or grow their human-resource line while increasing AI tool spend will compound both advantages; teams that swap the human investment for the platform investment will find their thought leadership flattens into generic AI output that the organic search and social distribution layer increasingly down-ranks. "Content marketing works" is no longer the headline. "Content marketing works only when staffed properly" is.
How they got the data
The Content Marketing Institute fielded the 16th annual B2B Content Marketing Benchmarks, Budgets, and Trends survey from 24 June to 14 August 2025, in partnership with MarketingProfs and sponsored by Storyblok. The final sample of 1,015 B2B marketers covers in-house, agency, consultancy and other roles across sectors including technology, professional services, manufacturing, healthcare and education, with respondents drawn predominantly from North America (United States and Canada) and a smaller international long tail. The survey covers programme effectiveness, content strategy, AI adoption and impact, thought leadership, first-party data, account-based marketing, top-performing content types, distribution channels, measurement and 2026 budget allocation, with year-on-year comparisons against the equivalent 2025 outlook.
CMI's methodology note covers sample composition, fielding period and question wording. The full report is free to download from the CMI research hub with email registration, and the public summary article on the CMI site carries the headline charts. CMI has run the survey under the same instrument family since 2010, supporting longitudinal comparisons across the discipline's maturity, with the B2C edition published separately each autumn.
