News Release

NEW YORK, NY, USA, 9 July 2019—Gartner, the world’s leading information technology and advisory company, ranked Deloitte as the number one worldwide consulting service provider for the second consecutive year, based on 2017 and 2018 revenues in its April 2019 report titled, Gartner Market Share Analysis: Consulting Services, Worldwide, 2018*. Of note, this is the eighth time in total that Deloitte has received the #1 ranking by revenue.

“We believe that Gartner’s independent assessment reflects Deloitte’s ability to bring together advice, insights, and technology to deliver a distinctive value proposition - enabled by Deloitte’s own assets and those created with alliance partners,” says Sam Balaji, Deloitte Global Consulting leader. “Within any market or industry, Deloitte addresses the heart of clients’ business issues across the globe, leading them on their journey to imagine, deliver and run the future. And in doing so, Deloitte is reshaping the future of the consulting market.”

According to the report, “the global consulting market grew 9.0% in constant currency in 2018, reaching $188 billion. Digital business acquisitions are a primary driver of growth among the largest providers. Robust growth among IT-focused providers indicates rising demand for technology consulting.”
