Question: What are the top 20 IT services companies in the world?

Answer:

The top IT services companies (focusing on consulting, outsourcing, digital transformation, and services for banks/big corporations, similar to Accenture/Infosys) are ranked here primarily based on Brand Finance IT Services 25 (2026) report, which measures brand value as of early 2026. This is a key industry benchmark for these firms, reflecting global perception, strength, and relevance in IT services/outsourcing.

The total brand value of the top 25 reached USD 167.2 billion in 2026 (up 2% from 2025). Indian firms hold a strong position (claiming about 36% of the total value), while Western and Japanese players lead in consulting depth.

Here are the top 20 (top 10 are explicitly detailed in sources; positions 11–20 are inferred from mentions of the top 25 and common industry leaders in this category, as full top 25 lists are partially available):

  1. Accenture (USA/Ireland) — $42.3 billion brand value — Global leader in strategy, consulting, digital, tech, and operations outsourcing; dominant in banking/finance transformations.

  10. CGI (Canada) — $4.3 billion — IT and business consulting, strong in finance, government, and utilities outsourcing.

  2. Persistent Systems (India) — Noted as fastest-growing in 2026 report

  9. Deloitte Consulting (USA) — Advisory/IT services arm
  10. Hexaware Technologies (India) — Or similar mid-tier like Atos/others in top 25.

Note: Exact positions beyond top 10 vary slightly by metric (brand value vs. revenue vs. market share). Revenue-based rankings (e.g., TCS ~$30B+, Accenture larger) often place TCS/Accenture at the top. These firms dominate large-scale outsourcing contracts for banks (core banking, payments, compliance) and corporations (ERP, cloud migration, AI/digital).

Indian players excel in cost-effective, large-scale delivery, while others lead in premium consulting/strategy.
