What happened
Forrester's 2026 spend research tracks a sharp divergence. 83 percent of B2B marketing decision-makers say they expect marketing investments to grow this year, with 40 percent expecting increases of 5 percent or more. The share expecting overall agency budget increases fell 13 percentage points year over year, and nearly half of respondents now expect agency spend to stay flat. Gartner's parallel CMO Spend Survey puts the median B2B marketing budget at 9.1 percent of revenue, with software at 11.4 percent. Where is the money going instead? Forrester names ABM, intent data, AI tooling, and senior strategic talent, with CMOs pulling dollars out of broad-reach demand generation and unfocused content production.
Why the B2B agency budget squeeze matters now

Two founder-side questions come out of the same data. First, if you sell agency services, the ask has changed. Buyers now expect measurable AI leverage, senior strategist attached to the account, and pricing that reflects outcomes rather than headcount. Retainers billed for junior labor on generic content are the exact spend Forrester says is being cut. Second, if you buy agency services, this is the moment your leverage is highest. Agencies that lost their expected budget lift are more open to trials, outcome-based pricing, and narrower scopes than they were twelve months ago.
- Reprice around senior labor and AI outputIf you run an agency, retire your junior-heavy retainer and package around one senior operator plus AI tooling. Buyers who cut generic content spend are still buying strategy, differentiation, and speed. That is the offer 83 percent of marketers expecting to grow will still fund, and it defends against the trend that just cut agency budget expectations by 13 points.
- Renegotiate every retainer this quarterIf you buy agency services, use the Forrester data in your next renewal conversation. Ask your agency directly which line items they can retire, replace with AI-assisted output, or restructure around outcomes. Half of your peers are freezing agency spend, so your agency has a real reason to keep you and less pricing leverage than they had last cycle.
- Move the freed budget into intent data or ABMForrester names ABM, intent data, AI tooling, and senior strategic talent as the winners of this reallocation. Do not cut agency spend and pocket it. Route the freed money into one of those categories that your team already has enough context to run, and tie the shift to a specific pipeline number so the reallocation is measurable inside a quarter.
What to do this week
Open your marketing budget spreadsheet and split agency line items into two columns: senior strategic work and everything else. Add up the everything-else column, then ask what would happen if that dollar amount moved to ABM, intent tooling, or a senior in-house hire. Send that comparison to your CFO before your next planning conversation. You will either free budget or force a much clearer agency conversation. Either outcome puts you ahead of half the market that is just freezing spend passively this quarter. Time the conversation ahead of your next quarterly planning cycle so any change lands cleanly in the budget instead of getting revisited mid-quarter. The reallocation happens fastest when it starts with numbers a CFO already trusts.
