Worldwide spending on Information Technology is on track for a historic 14 percent increase in 2025, marking the fastest growth since 1996, when Windows 95 and the early internet drove a tech supercycle.
According to IDC’s latest Worldwide Black Book, AI infrastructure investments are now fueling a new era of IT spending growth.
“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,” said Stephen Minton, Group Vice President at IDC.
Here are 10 key insights from IDC’s forecast:
1. IT spending to reach $4.25 trillion in 2025
Total global IT spending — including hardware, software, and IT services — is forecast to reach $4.25 trillion this year, driven largely by AI investments and enterprise digital transformation.
2. Total ICT spending to approach $7 trillion
When telecom and business services are included, overall ICT spending is projected to near $7 trillion in 2025, reflecting widespread investment across industries.
3. AI infrastructure is the main growth driver
IDC notes that the current spending surge is powered by massive AI infrastructure investments by service providers, creating a tech-driven economic supercycle.
4. Enterprise software spending surges by 14 percent
Software investment remains robust, as organizations accelerate cloud migration, security, analytics, and AI-driven optimization projects.
5. Q1 2025 IT spending posts fastest quarterly growth in 29 years
Front-loaded PC shipments ahead of anticipated tariffs helped IT spending jump 16 percent in Q1, marking the fastest quarterly growth since the early 1990s.
6. Enterprise IT spending shows steady growth
Enterprise IT budgets rose 11 percent in Q1 and 10 percent in Q2, reflecting ongoing commitment to digital transformation and infrastructure upgrades.
7. Service provider datacenter spending to soar 86 percent
Spending on servers, storage, and network equipment by service providers is expected to reach nearly $500 billion, highlighting the importance of AI deployment and cloud expansion.
8. Strong momentum continues into 2026
IDC forecasts IT spending growth of 10 percent in 2026, slightly slower than 2025 but still historically strong, indicating sustained confidence in technology investments.
9. Potential headwinds include memory shortages and PC price increases
While demand remains strong, IDC highlights risks such as memory component shortages that could increase PC prices, and ongoing global economic uncertainties.
10. Resilient tech investment even in economic slowdown
Despite macroeconomic concerns, most enterprises plan to maintain or increase IT budgets in 2026. IDC emphasizes that the likelihood of a major downturn similar to the 2001 IT crash is low.
This robust growth underscores the transformative role of AI and digital infrastructure investments, establishing IT as a key driver of global economic growth in 2025 and beyond.
