Generative AI demand is fundamentally reallocating enterprise technology budgets, shifting capital away from traditional managed services and toward massive cloud infrastructure investments. According to the latest Americas ISG Index™ report from Information Services Group (ISG), the combined technology services market reached a record $27.5 billion in annual contract value (ACV) during the third quarter. This represents a 61 percent year-over-year increase, marking the fastest growth rate ever recorded for the region. While the broader market is expanding at an unprecedented pace, the underlying data reveals a stark divergence between the explosive growth of "as-a-service" models and the continued contraction of legacy managed services contracts.
Rapid XaaS Expansion and Cloud Infrastructure Surges
The primary engine behind this market acceleration is the "as-a-service" (XaaS) segment, which saw its combined infrastructure-as-a-service (IaaS) and software-as-a-service (SaaS) ACV hit $21.6 billion. This 100 percent year-over-year increase is the fastest growth ever recorded for the XaaS category, which has now maintained double-digit growth for ten consecutive quarters. Within this segment, cloud infrastructure services—the foundational compute capacity required to run AI models—surged by 129 percent to reach $18.1 billion. This massive spike suggests that enterprises are prioritizing the raw processing power and scalable storage necessary for AI deployment over other IT expenditures.
Complementing this infrastructure boom, cloud-based software services also saw significant momentum, rising 21 percent to a record $3.4 billion. ISG notes that software demand is increasing as platforms evolve into primary distribution layers for AI capabilities. This shift is forcing hyperscalers to aggressively expand data center footprints to meet the compute capacity requirements of both frontier AI providers and large-scale enterprises. Consequently, XaaS now represents 76 percent of the combined market through the first nine months of the year, its highest share on record.
Managed Services Contraction Amid AI Budget Reallocation
While infrastructure spending is accelerating, the managed services market is experiencing a notable downturn, falling 6 percent to $6.0 billion in the third quarter. This decline marks the third time in the last four quarters that the market has contracted, a trend not seen since 2019. Within this segment, IT outsourcing (ITO) fell 7 percent to $4.8 billion, driven by a 2 percent dip in application development and maintenance (ADM) and a significant 27 percent drop in bundled ADM and infrastructure services. Business process outsourcing (BPO) also declined by 6 percent to $931 million, despite some growth in finance and accounting and facilities management.
The data suggests that enterprises are utilizing managed services as a cost-containment lever to fund their high-priority AI initiatives. ISG vice chairman Todd Lavieri indicates that while managed services remain necessary for bottom-line improvements, the "big bets" are currently being placed on cloud infrastructure. This shift is reflected in contract volumes; managed services contracts awarded fell 11 percent year-over-year to 426. Furthermore, the value of "mega-deals" (contracts exceeding $100 million) dropped 64 percent compared to the previous year. Interestingly, while new scope ACV fell 34 percent, the value of restructured deals rose 58 percent to an all-time high, suggesting a focus on optimizing existing agreements rather than launching massive new outsourcing engagements.
Key Takeaways
- The Americas technology services market reached a record $27.5 billion ACV in Q3, growing 61 percent year-over-year.
- Cloud infrastructure services demand surged 129 percent to $18.1 billion, driven by the compute requirements of AI.
- Managed services declined 6 percent to $6.0 billion, as enterprises shift spending toward XaaS and AI capabilities.
TechInsyte's Take
In our view, the ISG data confirms a structural pivot in enterprise IT spending that is moving from "keeping the lights on" to "powering the intelligence." The 129 percent surge in cloud infrastructure is not merely a cyclical uptick; it is a fundamental reallocation of capital toward the compute-heavy requirements of the generative AI era. The fact that managed services are being used as a "cost lever" to fund these AI bets suggests that CIOs are facing intense pressure to find efficiencies in legacy operations to finance the high cost of AI adoption. This creates a bifurcated market: a hyper-growth sector centered on hyperscalers and XaaS providers, and a shrinking, highly competitive landscape for traditional managed service providers. For infrastructure leaders, the challenge is no longer just about scale, but about the speed at which they can secure and deploy the compute capacity required by these rapidly evolving AI workloads.
Questions & Answers
How is AI specifically impacting the distribution of enterprise IT budgets?
AI is driving a massive shift toward cloud infrastructure and software services (XaaS), which grew 100 percent year-over-year. Conversely, enterprises are reducing spending in managed services, using those cost savings to fund the high capital requirements of building out AI capabilities and securing necessary compute capacity.
What does the decline in managed services mega-deals signal for service providers?
The 64 percent drop in mega-deal ACV, combined with a 34 percent drop in new scope ACV, suggests that enterprises are moving away from large-scale, new outsourcing commitments. Instead, the 58 percent rise in restructured deals indicates a preference for optimizing and renegotiating existing contracts to extract more value or reduce costs.
Which industries are leading the current wave of technology services spending?
Consumer packaged goods (CPG) and retail are seeing the most aggressive growth, with ACV rising 134 percent and 56 percent, respectively. Other significant gainers include media and telecoms (up 46 percent) and healthcare and pharmaceuticals (up 32 percent).
What is the long-term outlook for cloud-based XaaS according to ISG?
ISG has significantly increased its growth forecast for cloud-based XaaS to 60 percent (up from 30 percent previously). Within this segment, IaaS is expected to see an 80 percent growth rate, while SaaS is projected to grow by 12.5 percent.
