Deloitte ranked No. 1 consulting service provider worldwide by revenue in Gartner® Market Share report

News Release

NEW YORK, NY, USA, 12 July 2023 — For the sixth consecutive year and the eleventh time in total, Deloitte has been ranked No. 1 by revenue according to Gartner Market Share report, in its June 2023 report titled, Gartner Market Share Analysis: Consulting Services, Worldwide, 2022. Deloitte, which recently received a Strong vendor rating, the highest possible rating from Gartner in their 2023 Vendor Rating report, was also ranked first in terms of business consulting and technology consulting services for the second consecutive year.

“We believe, these recognitions demonstrate Deloitte’s success in bringing together strategic insights and technology-enabled solutions to create value and drive impact for clients,” says Heather Stockton, Deloitte Global Consulting leader. “We believe they reflect Deloitte’s continued commitment to leveraging the breadth of our multi-disciplinary capabilities and investing in the next-generation offerings and technology ecosystems to provide our clients with competitive advantage.”

Gartner reports, “The consulting market grew 14.0% in USD (20.1% in constant currency) to $266.3 billion in 2022. Consulting services experienced high demand as clients continued to accelerate their digital business transformation, while increasing their reliance on external consultants due to the talent crunch.”

According to the report, Deloitte's annual growth rate is 15.4% in 2022, reaching revenues of about US$33 billion. Fueled by growth in its technology consulting space – we feel that Deloitte’s global network IT services growth has outpaced the global IT services markets for the past six years.
