Top 50 IT Outsourcing Companies in the World: 2026 Edition

Accenture plc is the largest company in this ranking by a wide margin. Its annual report on Form 10-K for the fiscal year ended 31 August 2026 records revenues of US$74.18 billion, more than twice the figure of the next-largest entry. The filing states that the company employed approximately 814,000 people at that date and that it works with roughly three quarters of the Fortune Global 100 and Fortune Global 500, as well as every G7 government. Accenture is incorporated in Ireland, with its principal executive office in Dublin, and its shares trade on the New York Stock Exchange. Its outsourcing work sits alongside consulting, systems integration, managed services and industry-specific operations.

NTT DATA Group Corporation is the IT services arm of the Japanese telecommunications group NTT. Its corporate profile gives consolidated net sales of ¥4,638.7 billion for the fiscal year ended 31 March 2025 and a consolidated workforce of 197,800 people. The company's disclosure archive includes a notice dated 25 September 2025 announcing the delisting of its shares, after which NTT DATA became a wholly owned subsidiary of its parent. Because it is no longer listed, this ranking uses the most recent full-year figure on the company's own profile page. That figure is one fiscal year older than the data used for most other entries. NTT DATA provides consulting, systems integration, application management, infrastructure and data-centre services across Japan, the Americas, Europe and Asia-Pacific.

Tata Consultancy Services, part of the Tata group, reported revenue of ₹2,67,021 crore for the fiscal year ended 31 March 2026, up 4.6% in rupee terms and down 2.4% in constant currency. Total contract value signed during the year was US$40.7 billion. At year end TCS employed 5,84,519 people, according to its results statement. That is 23,460 fewer than a year earlier, and the company linked part of the fall to a restructuring programme carried out during the year. Its annual revenue is about the same size as NTT DATA's. TCS publishes a US-dollar figure, but this ranking converts its rupee revenue at the Federal Reserve's 2025 average rate so that all rupee reporters are treated the same way.

Capgemini SE reported 2025 revenues of €22,465 million, up 1.7% as reported and 3.4% at constant exchange rates. Fourth-quarter growth reached 10.6%, helped by the consolidation of two acquisitions closed in that quarter, WNS and Cloud4C. The company invested €3.8 billion in acquisitions during the year, mostly for WNS, which significantly expanded its business process services. Headcount at 31 December 2025 was 423,400, up 24% year on year. About two thirds of the workforce (279,200 people) was offshore. North America accounted for 29% of group revenue.

CACI International reported revenues of US$9.57 billion for the fiscal year ended 30 June 2026.

Its work combines enterprise IT, software development and network modernisation with mission technology in intelligence, electronic warfare and space.

Atos SE reported 2025 revenue of €8,001 million, down from €9,577 million in 2024. Its operating margin doubled to €351 million, or 4.4% of revenue.

It had 4,331 employees at 31 March 2026, compared with 4,406 a year earlier. Sify is headquartered in Chennai and its American depositary shares trade on Nasdaq. Unlike most companies in this list it owns physical infrastructure. Its revenue comes from enterprise network services, colocation data centres, cloud and managed services, and digital services sold mainly to Indian enterprises and government bodies. That makes it closer to infrastructure outsourcing than to offshore application development, and it gives it a much smaller headcount relative to revenue.

CI&T was founded in Brazil in 1995. It reported 2025 revenue of US$489.7 million in its annual report on Form 20-F. The company is incorporated in the Cayman Islands and listed on the New York Stock Exchange, but its roots and much of its delivery are in Brazil. Its 20-F reports a 15.7% increase in headcount to 7,993 employees at 31 December 2025, from 6,907 a year earlier, which was the main reason personnel costs rose. CI&T provides digital product engineering, data and AI services and application modernisation, and it uses nearshore delivery from Brazil and Colombia for clients in North America, Latin America, Europe and Asia. Financial services and consumer goods companies are among its largest client groups.

Grid Dynamics Holdings reported 2025 revenue of US$411.8 million in its Form 10-K filed on 5 March 2026. The company is headquartered in San Ramon, California, and listed on Nasdaq. Grid Dynamics sells platform and product engineering, cloud migration and data and AI work, mainly to technology, retail, consumer-goods and financial-services companies in the United States. It is among the smallest companies in this ranking and has a relatively concentrated client base, so changes in spending by a few large clients have a visible effect on its results.

Mastech Digital reported 2025 revenues of US$191.4 million. It is headquartered near Pittsburgh, Pennsylvania, and the 10-K describes approximately 1,500 consultants working across many industries and in both digital and mainstream technologies. The company reports two segments, data and analytics services and IT staffing services. It began by placing offshore technology professionals in the United States and later moved to a domestic recruiting model supported by an offshore recruitment centre set up in 2003. Mastech is the smallest company in this ranking. It is included as an example of the US staffing-led IT services companies that compete with larger outsourcers for project and contract work.
