Gartner’s latest outlook frames AI as a massive capacity-investment cycle. Worldwide AI spending is forecast to reach $2.7 trillion in 2026, a 49.5% increase from 2025. Yet the forecast should not be read as evidence that most organizations have already turned AI pilots into repeatable, profitable operating models. The largest buyers are technology providers building the compute, servers and cloud capacity needed to run future workloads.22

The forecast has moved higher throughout 2026
The direction of Gartner’s revisions is as important as the headline number. Its January outlook projected $2.52 trillion in 2026 AI spending, up 44% year over year. By May, the estimate had risen to $2.59 trillion, or 47% growth. The latest reported forecast is approximately $2.7 trillion, with 49.5% annual growth.41

That sequence signals that projected demand for AI capacity has continued to outrun earlier expectations. Reported analysis of Gartner’s longer-range forecast expects total AI spending growth to remain rapid in 2027, at roughly 36%, before moderating in later years.17
Infrastructure is still the center of gravity
The bulk of spending is not primarily going to standalone AI applications. It is going to the physical and cloud foundation for training and serving models: AI-optimized infrastructure as a service, servers, network fabric, processing semiconductors and devices. In Gartner’s May forecast, AI infrastructure represented more than 45% of total worldwide AI spending.29
Technology providers account for 35% of AI spending in the latest reporting, purchasing AI-optimized servers, cloud infrastructure and chips to build, deploy and operate models and agents.22
This helps explain why memory-related price pressure has not stopped the build-out. Gartner’s position is that demand for infrastructure supporting expected workloads remains strong and relatively insensitive to those cost increases.49 In practical terms, hyperscalers and major service providers are prioritizing capacity availability over near-term component-price discipline.
Software, services and models are growing around the build-out
Infrastructure may dominate the spending mix, but it is not the only growth area. Gartner’s May outlook estimated 2026 spending of about $585.5 billion for AI services, $453.2 billion for AI software, and $64.25 billion for AI platforms and models; the latter category was forecast to grow 63.4% from 2025.38

These categories matter because usable enterprise AI depends on more than model access. Organizations need integration, data preparation, governance, workflow design, monitoring and operational support. The infrastructure boom creates the conditions for those downstream purchases, but it does not guarantee that every deployment will produce value.
Gartner also expects enterprise model use to become more specialized: by 2027, more than half of the generative AI models used by enterprises are projected to be industry- or business-function-specific, up from about 1% in 2024.12
The software mix is moving from assistants to agents
A key shift within AI software is from conversational assistants toward systems designed to complete bounded, multi-step work. Reported analysis of Gartner forecast data says spending on embedded chatbots and assistants peaks in 2027, while embedded agentic AI overtakes it that year and continues expanding afterward.45
That transition is strategically significant. Assistants can help users draft, search or summarize; agentic systems are intended to invoke tools and advance work across a workflow. But greater autonomy also increases the importance of permissions, evaluation, auditability and usage controls.
The “Trough of Disillusionment” is a warning about ROI, not a spending collapse
Gartner characterized 2026 as a period of disillusionment for AI, where early excitement meets the operational reality of implementations that fail to deliver expected results.41

That is compatible with very high spending. Infrastructure providers can invest heavily in capacity while individual enterprises remain cautious about which use cases are reliable, economical and governable enough to scale. Publicly available material in this source set does not establish a definitive Gartner-wide production deployment rate, so precise claims about how many enterprises have scaled AI should be treated carefully.
What enterprises should take from the forecast
The immediate planning implication is not simply to spend more on AI. It is to distinguish between a market-wide infrastructure race and a company’s own ability to create measurable value.
Priorities for buyers include:
- Measure economics by workflow. Track model, inference, integration and human-review costs against a defined business outcome.
- Build usage controls early. Budgets, rate limits and monitoring are especially important as agents conduct more multi-step work.
- Preserve architectural flexibility. Keep data, evaluation and orchestration layers portable where possible rather than tying the entire system to one proprietary model or cloud environment.
- Address sovereignty and exit risk in procurement. Gartner’s latest reporting specifically identifies vendor lock-in, data sovereignty and runaway costs as continuing concerns, even as buyers keep adopting proprietary capabilities.

Bottom line
Gartner’s $2.7 trillion forecast shows that AI spending is accelerating sharply into 2026 and likely remains elevated through 2027. But it is chiefly a story about the construction of global AI capacity. The crucial test for enterprises is still narrower: whether they can turn that capacity into secure, well-governed workflows with measurable unit economics and durable business results.22
