What happened
The 2026 Gartner CMO Spend Survey, which polled 401 CMOs, quantified the shift to consumption-based pricing more clearly than any prior year. Fifty-six percent of respondents increased how much of their martech budget they allocated to usage-priced tools over the past 12 months. Sixty-two percent plan to invest more in martech overall next year even as martech as a share of budget fell to a five-year low of 19.4 percent. AI as a line item now consumes 15.3 percent of the marketing budget, but only 30 percent of CMOs say their organization is ready to scale AI usage. MarketScale's follow-up analysis flagged that the collision between rising consumption-based tools and immature AI governance is producing quarterly overruns, especially in orgs that piloted an AI feature in one team and then watched adoption spread horizontally before finance caught up.

Consumption-based pricing was supposed to be the CMO-friendly model. Pay for what you use, scale up when it works, kill it if it does not. The math breaks in a specific way when AI is on the meter. AI usage tends to grow non-linearly — one team adopts, then a second team copies the workflow, then an integration lights up a background use case, and the invoice quadruples between quarters. Traditional seat-based pricing had a natural cap: the seat count. Consumption pricing does not. And because most 2026 martech budgets were built when consumption was under 40 percent of spend, forecasting models have not caught up. CMOs are entering 2027 planning without a reliable per-user AI-cost baseline, which is the number every 2027 budget conversation will require.
- Pull the last 90 days of consumption-based invoices and calculate per-user AI cost
Ask finance for every invoice tagged martech or AI where the price line varied more than 10 percent from the prior month. Divide total usage cost by weekly active users of the tool. That is your per-user AI cost baseline, and it is the number you will defend or negotiate in every 2027 budget conversation. Most CMOs do not have this number and will not survive planning without it.
- Set a hard usage cap on every consumption-priced AI tool this week
Every major consumption-priced vendor — including HubSpot Breeze, Salesforce Agentforce, and standalone AI writing tools — supports a cap or alert threshold. Set one now at 130 percent of current run rate. This does not stop growth; it stops surprise. When usage crosses the threshold, you get to decide whether to lift the cap or investigate why.
- Renegotiate any contract renewing before Q1 to include a token or usage floor
Consumption vendors will trade a lower per-unit price for a committed floor. If your usage is stable, you win on price. If your usage grows non-linearly, the floor caps your downside because you have already committed. Sixty-two percent of CMOs are increasing martech spend, so vendors are competitive on renewal terms right now.
By the numbers: Gartner puts 2026 marketing budget at 7.8 percent of revenue, with paid media at 31.4 percent, labor at 24.5 percent, martech at 19.4 percent — a five-year low — and AI at 15.3 percent. Fifty-six percent of CMOs increased consumption-based martech allocation year-over-year. AI-ready orgs are spending 21.3 percent on AI and getting 8.9 percent of revenue as budget.
What to do this week
Open your last 90 days of consumption-based martech invoices and calculate per-user AI cost across your top three vendors. Set a 130-percent-of-run-rate cap on each account before Friday. Flag any tool where the cost per user has grown more than 25 percent over the quarter — that is either a runaway workflow worth investigating or a pricing curve worth renegotiating. Bring the number to your next executive team meeting so 2027 planning starts from a real baseline.
