Global IT spending is expected to total $5,74 trillion in 2025, what does an increase of 9 represent,3% in relation to 2024, according to the latest forecast of theGartner, Inc.
“Current expenditure onGenerative Artificial Intelligence(GenAI) has been predominantly developed by technology companies that are building the necessary infrastructure to offer GenAI, affirmsJohn-David Lovelock, Vice President and Analyst at Gartner. "The CIOs (Chief Information Officerswill start spending on GenAI, going beyond proof of concepts, starting from 2025. More money will be invested, but the expectations that CIOs have about the capabilities of GenAI will decrease. The reality of what can be achieved with the current models of this technology and the state of the data from CIOs will not meet today's high expectations.”
Server sales continue to drive the Data Center segment
Spending on Data Center systems grew by almost 35% in 2024. Although a similar leap is not expected in 2025, the segment is expected to grow by nearly US$ 50 billion next year. This significant growth is driven by server sales, that should almost triple, increasing from over US$ 134 billion in 2023 to US$ 332 billion by 2028 – including more than an estimated US$ 257 billion for 2025

| Data Center | 318.008 | 34,7 | 367.171 | 15,5 |

"GenAI will easily surpass the effects that Cloud providers and outsourcing had in previous years regarding Data Center systems", says Lovelock. "It took 20 years for Cloud and outsourcing providers to reach $67 billion a year in servers". "The demand for GenAI will help nearly triple server sales from 2023 to 2028"
Software and IT services will drive growth
Software spending is expected to increase by 14%, reaching US$ 1,23 trillion in 2025, above the growth of 11,7% that is estimated for 2024. Meanwhile, IT services are expected to grow 9,4%, reaching US$ 1,73 trillion in 2025, what does an increase of 5 represent,6% in 2024
"Software and IT services are major drivers of IT growth", Lovelock claims. "It is expected that spending in these segments will be on projects related to AI", including email and content creation. This is a market that, despite its age and having been established with a small number of participants, will add US$ 6,6 billion to global spending in 2024 and US$ 7,4 billion in 2025, partly due to products and services withGenerative Artificial Intelligence.”
Gartner predicts that $500 billion will be added to spending each year in terms of growth rates. With that in mind, global IT spending is expected to exceed $7 trillion by 2028.”
