2026 IT Budget Benchmarks
Global IT spending in 2026 is projected at $6.39 trillion, up 14.5 percent year-on-year per Gartner's October 2026 forecast (revised from $6.37 trillion, up 14.2 percent, in July). Growth is driven by AI infrastructure ($879B data centre systems, +73.8 percent; $292B infrastructure-as-a-service, +31.3 percent) and GenAI software. IT services remains the largest segment at $1.56T. For 2027 Gartner forecasts $7.35 trillion, up 15.0 percent.

Five-Segment 2026 Forecast
The 14.5 percent global growth is unevenly distributed across segments. Data centre systems is growing far faster than everything else because of the AI infrastructure buildout, while device spend is lifted by memory-driven price rises. Communications services is the slowest-growing segment. The detailed forecast below is from Gartner's October 2026 release.
| Segment | 2026 Spend | Growth vs 2025 | Key Driver |
|---|---|---|---|
| Data centre systems | $879B | +73.8% | AI infrastructure: hyperscaler server and data centre buildout, high-performance compute demand. |
| Infrastructure as a service (IaaS) | $292B | +31.3% | AI-optimised cloud compute; reported as a separate line by Gartner. Fastest-growing cloud segment. |
| Devices | $847B | +7.2% | Spend lifted by rising hardware and memory costs. |
| Software | $1.46T | +15.2% | GenAI and AI-embedded SaaS. Gartner's September 2026 AI forecast has generative AI model spending up 117 percent. |
| IT services | $1.56T | +4.4% | Largest segment. Consulting, application and infrastructure implementation, managed services. |
| Communications services | $1.35T | +4.1% | Stable recurring revenue, slowest growth. Mature segment. |
Top CIO Priorities for 2026
The two survey figures below are from Gartner's October 2025 release of its 2026 CIO and Technology Executive Survey; the security figure is Gartner's security spending forecast. FinOps and technical debt are budget themes, not survey statistics.
Agentic AI
64% plan to deploy within 24 monthsGartner 2026 CIO and Technology Executive Survey, more than 2,500 respondents. Agentic AI is the shift from AI pilots to systems that carry out multi-step work, and it brings new software, inference and governance costs.
AI investment
Expected to grow 35%+ a yearFrom the same Gartner survey release, which describes this growth as happening inside a very constrained IT budget environment. In practice the AI line grows by squeezing others.
Cybersecurity
$244B worldwide in 2026Gartner's 2026 information security spending forecast. Drivers include the threat landscape and DORA / NIS2 compliance.
FinOps and cost optimisation
Board-level priorityAs AI infrastructure costs scale, finance teams demand visibility and accountability. FinOps moved from engineering discipline to CFO concern.
Technical debt remediation
Prerequisite for AILegacy systems and fragmented data slow AI adoption, so remediation work increasingly sits in front of AI projects in the budget.
What This Means for 2026 IT Budget Planning
Five Practical Implications
- !Add a named AI line item if you have not already. AI pilots are becoming production systems with real infrastructure and software costs (Copilot, Salesforce Einstein, custom LLM ops).
- !Check the security line against peers. IANS puts security at 10.9 percent of the IT budget in 2025, down from 11.9 percent in 2024, because overall IT budgets grew faster than security spend. If yours is well below that, find out why before the board does.
- !Cloud cost management has become non-negotiable. FinOps practices (tagging, showback, commitment management) belong in any budget with a material cloud line. AI workload growth makes this acute.
- !A Gartner analyst described the IT budget environment as very constrained, even as AI investment grows. Come with benchmark data (industry, size, regional) to justify the ask. The calculator on this site exists for exactly this conversation.
- !Build versus buy is shifting. More capabilities are available as AI-embedded features in existing SaaS. Custom build costs less than they did 12 months ago because of AI coding assistants.
