This figure has been steadily growing since 2015, and is expected to reach**** billion U.S. dollars in 2021. These values only include spending on legal services by companies with over * U.S. dollars in revenue.
One of the reasons why the U.S. has a disproportionately large legal services market, relative to the population and economy of other actors such as Europe and China, is the connection many of the global Big Law firms have with the United States. Of the largest law firms in the world in 2018, only three were not founded in the United States (Dentons, Clifford Chance and Allen & Overy). These large global firms generally base the highest portion of their workforce in the U.S. and often run any large multinational projects from their U.S. office.
