Accenture Leads Global IT Service Market, Large Indian IT Firms Face Share Pressure

Overview

This report uses Gartner global IT service market share data to systematically analyze the trend changes in market position of major IT service vendors across dimensions such as global, regional, industry verticals, and service lines. The core finding is that the market shows obvious bifurcation: global leader Accenture continues to expand, while large Indian IT firms suffer share pressure, and mid-tier Indian IT vendors rise on the wave of this trend. The report aligns these trends with UBS's rating stance, giving Buy ratings to assets such as Accenture, Infosys, HCL, and Persistent.

Core views

Global Market Landscape and Competitive Dynamics Accenture has established absolute leadership in the global IT service market. As of the end of 2025, its market share reached 4.5%, the highest among all analyzed vendors. More importantly, the company achieved the most extensive share growth over the past decade, covering all major geographic regions and service lines. This indicates Accenture's sustained strong capability in adapting to market changes and developing new businesses. In contrast, Atos has become the worst-performing vendor, losing market share in all regions and industry verticals, with long-term performance being sluggish. Differentiation among Indian IT Firms The report reveals significant differentiation within Indian IT firms. Large incumbents TCS, Wipro, and TechM face significant market share pressure recently (CY25). Among them, TCS's downturn in ROW (Rest of World) is mainly attributed to the scale reduction of BSNL projects; Wipro and TechM face more widespread multi-year declines. This downward pressure suggests challenges for large enterprises in adapting to client demand changes or coping with emerging competitors. Conversely, Infosys and HCL successfully defended their share, showing stronger resilience. Even more noteworthy is that mid-tier Indian IT vendors (LTIM, Persistent, Coforge) have achieved the most stable and sustained long-term growth over the past five years, although recent growth increments are relatively moderate, the long-term trend has strong certainty. Geographic and Vertical Business Differences In terms of geography, Accenture is the most consistent share grower across regions. Americas and Europe show the strongest growth, with a five-year CAGR of approximately 8%, while Asia Pacific is only 4%, indicating developed markets are more favorable. Atos consistently loses share in all regions, while large Indian enterprises present region-specific pressures—for example, TCS downturn in ROW. Looking at industry verticals, BFSI (Banking, Financial Services, Insurance) and Manufacturing drove recent share growth for Accenture and Cognizant. However, observing from a five-year dimension, healthcare and retail showed structural decline, where even leading vendors were not spared. Manufacturing and energy utilities performed strongest, with a five-year CAGR of approx 11%, followed by BFSI and healthcare (approx 6%), while retail and communications were the weakest (3-4%). Service Line Differentiation and the Divide Between 'Operations' vs 'Change' Work In terms of service lines, Accenture is the most consistent share grower, especially dominating in application realization, AMS (Application Management Services), and infrastructure. TCS and Wipro lost share in most service lines in CY25, while Atos faced broad pressure. Five-year data reveals deeper structural changes: traditional 'operations' type work (such as parts of AMS and infrastructure) supported share growth (including Accenture and mid-tier vendors like Coforge/Persistent), while application realization and consulting-type 'change' work faces broader erosion, potentially flowing to smaller or specialist consulting firms. From industry growth speed perspective, business consulting and application realization grew fastest (15-17% CAGR), while infrastructure services lagged relatively (4-5% over 5 years).

Analysis framework

The report adopts a layered progressive analysis framework. First, at the overall global level, relative competitiveness of each vendor is judged through market share absolute values and trend changes (10 years, 5 years, YoY). Second, slices are analyzed separately along three dimensions of geography, industry verticals, and service lines to reveal structural characteristics of market dynamics. Third, short-term (YoY) and medium-to-long term (5 years, 10 years) changes are compared to distinguish between persistence and cyclicality of trends. This multi-dimensional analysis allows the report to capture both current market landscape (such as Accenture's dominant position) and identify deep structural changes (such as the 'operations' vs 'change' division in service lines and structural decline in certain verticals). The report explicitly states Gartner data as the basis but conducts independent interpretation by UBS, and maintains accuracy in data explanation by including M&A impact in disclaimer notes. Finally, the report links analysis conclusions with UBS's rating stance (Buy: Accenture, Infosys, HCL, Persistent; Neutral: Others), without making specific investment advice.

Methodology notes

• Industry Analysis FrameworkSupply and Demand Framework

  Through analyzing distribution changes of market share across different geographic regions, industry verticals, and service lines, the report implicitly adopts supply-side competitive analysis. Fluctuations in share for different vendors in specific areas reflect the degree of match between their supply capabilities (such as Accenture's cross-domain capability) relative to demand directions.

  Demand for IT service market comes from enterprise clients' digitalization, cloud computing, and business process outsourcing needs; the supply side is competed by IT service vendors with different capabilities. By tracking share changes, the report essentially observes the supply matching rate of each vendor. For example, Accenture maintaining share in high-end consulting work of 'change' type (application realization), while 'operations' type work flows to small specialists reflects the evolution of demand direction from traditional operations to high-value change work.

• Industry Analysis FrameworkVolume-price decomposition

  When analyzing market share changes, the report implicitly distinguishes between 'volume' (overall growth rate of IT service industry: past 5 years and 10 years CAGR were 7% and 6%) and 'price' (relative position change of each vendor in total volume). A vendor's share loss may originate from overall market contraction or competitors gaining more incremental shares.

  Although overall IT service market is growing, growth speeds vary by region (Americas/Europe 8% vs Asia Pacific 4%), and growth varies across verticals (consulting 15-17% vs infrastructure 4-5%). Accenture's share growth reflects both its competitive success in high-growth areas and its development of new service lines. Conversely, some vendors may bear relative pressure in low-growth verticals.

• Industry Analysis Framework

  The report implicitly adopts 'Service Line Lifecycle' analysis. By distinguishing 'operations' type work (mature, highly competitive, trending towards small or specialist vendors) and 'change' type work (high growth, high value, dominated by large comprehensive vendors), the report reflects the impact of service line maturity on vendor strategy and share performance.

  Different types of IT services (such as AMS maintenance services vs application realization consulting) are in different stages of the industry lifecycle. Mature 'operations' services are easily fragmented and shifted down to small vendors, while high-growth 'change' services remain dominated by large comprehensive vendors due to the need for full-stack capabilities and customer relationships. By analyzing this differentiation, the report implicitly conveys possible future trajectory of competitive positions for different vendors.

• Competition and Strategy FrameworkEconomies of scale / learning curve

  Accenture's continued share expansion and mid-tier Indian vendors' long-term growth reflect the trade-off between scale and specialization advantages. Accenture gains advantage through global scale and comprehensive capabilities; mid-tier vendors establish competitiveness in specific fields through focus and agility.

  Large-scale IT service providers (such as Accenture) can achieve economies of scale through global resource pools, cross-selling, process reuse, etc., suitable for large clients and complex comprehensive projects. Although mid-tier vendors are smaller in scale, they can achieve learning curve advantages through faster decision-making, stronger specialization, and keen response to emerging demands, particularly in growth areas. This explains why both Accenture and LTIM/Persistent can achieve growth in different markets.

• Event Gaming and Behavioral Finance

  The report mentions the impact of BSNL project scale reduction on TCS ROW share, and distortion of market share data by M&A. This implicitly suggests short-term shocks to individual vendor share caused by specific clients or large project events.

  Market share changes of IT service vendors not only reflect long-term competitiveness changes but are also affected by major client events (such as termination or reduction of key projects, large-scale mergers). By citing BSNL cases and M&A disclaimers, the report reminds investors to distinguish between structural trends and event-driven volatility when interpreting share data.

Impact & implications

The report's market share analysis has multi-faceted implications for IT service industry investment and strategy. First, Accenture's continued dominant position reflects the core value of scale and comprehensive capabilities in complex, high-end IT service markets, and the corresponding investment thesis is the sustainability of its growth. Second, the share pressure on large Indian IT firms suggests these enterprises face challenges in business structure adjustment, with traditional 'operations' services facing downward pressure, requiring transformation towards higher-value 'change' work. Third, the long-term growth of mid-tier Indian IT firms (LTIM, Persistent, Coforge) indicates growth opportunities exist in the mid-tier market, where these vendors achieve differentiated competition through agility and specialization. Fourth, asymmetric growth in geographic dimensions (Americas/Europe vs Asia Pacific) suggests global IT service investment should focus more on leading vendors in developed markets and specific opportunities in emerging markets. Fifth, differentiation in industry verticals and service lines indicates investors should evaluate the alignment between each vendor's client structure and service portfolio with market growth directions. Overall, the report supports the Buy ratings given by the report to Accenture, Infosys, HCL, and Persistent, because these vendors either hold market leadership and continue to expand (Accenture), or successfully defend share and achieve growth in emerging fields (the other three).
