Global IT Budgets Surge as AI Infrastructure and Cloud Investments Accelerate
AI infrastructure spending and cloud adoption are driving the strongest global IT growth in nearly three decades.
Key Takeaways:
- Global IT spending is entering its fastest growth phase in decades, led by AI-driven infrastructure demand.
- Enterprises are accelerating cloud migration, software modernization, and large-scale PC refresh cycles.
- Strong momentum is expected to continue into 2026.
Global IT spending is set to surge 14 percent in 2025, marking its fastest expansion since 1996. The acceleration reflects a full-scale tech supercycle, driven by record AI infrastructure investment alongside rapid cloud adoption and widespread enterprise software upgrades.
According to IDC’s latest Worldwide Black Book, global spending on hardware, software, and services is expected to reach $4.25 trillion. Three major factors are driving the growth in IT spending. A surge in AI infrastructure investments is leading service providers to pour resources into datacenter hardware such as servers, storage, and networking equipment, with spending in this area projected to climb by 86% to nearly $500 billion.
Cloud migration and enterprise software fuel demand
Additionally, enterprises are accelerating their cloud migration and digital transformation initiatives, which are investing heavily in software for security, analytics, and optimization. The PC refresh cycle also contributed to early momentum in 2025.
“AI is the headline of IT market performance in 2025, but most of the actual AI investment this year is concentrated in service provider infrastructure,” said Stephen Minton, Group Vice President at IDC. “This AI investment is partly supported by enterprise spending on core IT products and services, which make up the strong revenue streams of the service providers investing heavily in AI deployment. In turn, this AI investment is supporting economic growth and stability, which in turn is supporting the ability of businesses to maintain their investments in cloud services and enterprise software. As a result, we’re currently experiencing a virtuous cycle of tech-driven macroeconomic growth.”
According to IDC, enterprise IT spending saw 16% growth in the first quarter, due to front-loaded PC shipments ahead of anticipated tariffs in the second quarter of 2025. This study found that IT spending grew 11% in Q1 and 10% in Q2.
Enterprise IT spending accelerates despite risks
In 2026, most businesses are planning to increase their overall IT budgets again, and there is no sign of any slowdown. IT spending is projected to grow by 10% in 2026, which is slower than the exceptional surge in 2025 but still represents a strong performance for the industry. Analysts believe that potential risks (such as memory component shortages and tariff-related impacts) could create challenges, but a major downturn similar to the 2001 crash is highly unlikely to happen.
As IT budgets surge toward AI and cloud investments, cybersecurity is quietly emerging as another critical growth factor. Beyond traditional security tools, demand for password management and identity protection solutions is accelerating. It’s driven by the rise in remote work, multi-cloud environments, and increasingly sophisticated cyber threats.
