The Current Size of the Interpreting Market

We estimate the market for interpreting services in 2019 at USD 7.6 billion.

This includes core services such as onsite interpreting, over-the-phone interpreting (OPI), video remote interpreting (VRI), video relay services (VRS), sign language interpreting, conference interpreting, equipment rental for interpreting, and related services.

Interpreting providers should calculate the addressable market for their services at 60 percent of the total figure. This is because not all interpreting services are outsourced to LSPs. Large institutions like the European Union and Hospital Systems employ staff interpreters as well as freelancers, rather than working with agencies.

Top companies concentrate 33.2% of industry revenue

Although M&A, and centralizations via government contracts are on the rise, the interpreting industry is still largely run by many small companies. All companies included in The Nimdzi Interpreting Index accounted for 33.2% of the interpreting industry in 2018.
