Combined market ACV up 20% in Q4, driven by 33% growth in cloud services

Managed services growth slows to less than 3%

Combined market ACV hits record $104 billion for the full year

ISG forecasts 18% growth for XaaS, 4.5% growth for managed services in 2025

Global spending on IT and business services rose by double-digits in the fourth quarter, fueled by a sharp increase in cloud demand driven by AI, according to the latest state-of-the industry report from Information Services Group (ISG) (Nasdaq: III), a leading global technology research and advisory firm.

Data from the ISG Index™, which measures commercial outsourcing contracts with annual contract value (ACV) of $5 million or more, show fourth-quarter ACV for the combined global market (both managed services and cloud-based services) at a record $28.2 billion, up 20 percent versus the prior year. It was the fourth consecutive quarter the combined market grew year over year, and the second straight quarter it established a new high for ACV.

A sharp increase in cloud spending propelled market growth this past quarter, with ACV for cloud services up 33 percent versus the prior year, to $17.7 billion. Within this segment, infrastructure-as-a-service (IaaS) soared 42 percent, to $13.4 billion, while software-as-a-service (SaaS) grew 12 percent, to $4.3 billion.

“Demand for cloud services continued its upward trajectory – a complete turnaround from the down market it faced in 2023,” said Steve Hall, president of ISG, and the firm’s chief AI officer. “We’re seeing enterprises reaccelerating their cloud migrations and looking to the cloud to power their AI ambitions. This is great news for the big three hyperscalers and their ecosystem partners, which are building more and more AI apps on hyperscaler platforms. Indeed, AI now accounts for about 6 percent of provider revenues – and climbing.”

Managed services, meanwhile, grew at a much more modest pace, up 2.6 percent in the fourth quarter, to $10.5 billion of ACV. Demand slowed sequentially, down 3 percent from the third quarter. Within this segment, IT outsourcing (ITO) was essentially flat (up 0.6 percent), at $7.9 billion, while business process outsourcing (BPO) advanced 9 percent, to $2.6 billion.

During the fourth quarter, 715 managed services contracts were awarded, up 6 percent from the prior year. Among them were 10 mega-deals (contracts with annual value of $100 million or more) with combined ACV of $1.7 billion, up 31 percent year over year. It was the first time since 2007-2008 the global market has produced at least 10 mega-deals for three consecutive quarters.

At the same time, the number of deals on the other end of the spectrum (those valued at between $5 million and $10 million) rose 14 percent from the prior year.

Full-Year Results

Combined market ACV for the full year was a record $104 billion, up 11 percent from the prior year.

The ACV of cloud-based services reached a record $62.4 billion, up 19 percent, with IaaS up 25 percent, to $46.6 billion, and SaaS up 4.6 percent, to $15.8 billion.

Managed services ACV advanced less than 2 percent, to a record $41.7 billion, as demand slowed from the average 6 percent growth of the previous two years. ITO was flat, at $30.6 billion, while BPO was up 6 percent, to $11 billion.

A total of 2,868 managed services contracts were awarded in 2024, up nearly 5 percent from the prior year, including 34 mega-deals, one less than in 2023. Meanwhile, the number of new-scope awards (1,926) and their combined ACV ($27 billion) were both up 6 percent, with new-scope ACV at a record high.

“Managed services bookings grew at a slower pace in 2024 compared with the previous two years, primarily due to continued pressure on discretionary spending, especially in the banking and manufacturing sectors, which make up nearly half of the contract value in the market,” Hall said. “That cost pressure, however, led to a second consecutive year of strong mega-deal activity as enterprises looked to move the needle on their cost profile through large-scale transformations.”

Hall said enterprise decision-making accelerated in the second half of 2024, noting an increase in the number of smaller deals in the $5 to $9 million ACV range. “This could be an indication that discretionary spending is beginning to loosen up.”

2025 Forecast

For the full year, ISG is forecasting 4.5 percent revenue growth for managed services, and 18 percent revenue growth for cloud-based services (as-a-service or XaaS).

“Looking at 2025, we expect a gradual recovery in enterprise demand for IT and business services,” Hall said. “We base our view on the likelihood the U.S. Federal Reserve will keep interest rates in restrictive territory, with at least two rate cuts expected, while the strong U.S. dollar continues to pose challenges for multinational corporations. In Europe, we are likely to see subdued growth, with the upcoming elections in Germany creating uncertainty in the market until the second half.

“At the same time, we see several macroeconomic tailwinds at play,” Hall continued. “AI spending continues to gain momentum, with hundreds of billions being spent on infrastructure, setting the stage for widespread adoption among enterprises and individuals. Productivity gains from AI are expected to be substantial, presenting a massive market opportunity. In managed services, we're seeing early signs of improvement in the BFSI [banking, financial services and insurance] sector as discretionary spending begins to pick up. Broader market demand could also improve, thanks to greater clarity on the rate-cutting cycle, enterprises acknowledging their growing technical debt, and the rapidly increasing demand for GenAI.”
