It may be a prominent, active language in the "market", but among Lisps it's not very mainstream, given that it lacks a lot of things that define a Lisp (which are more interactive, more dynamic, full languages, ...). I would consider it as "a Lisp" not so "mainstream", given that it is has very little backwards compatibility to earlier Lisps, is mostly a hosted language, is a blend of a not so functional language&platform (platform JVM is object-oriented) with functional datastructures, is very opinionated, is BFDL controlled, ... Clojure has also successfully spawned in the last years enough variants/tools/libraries/practice, ... , that it is now a diverse language family on its own.
