Maybe Clojure. In 2022 it took the top spot for "Top paying technologies" in the annual StackOverflow survey [0], and in 2023 it tied with other lispy languages [1].

That said, I don't think it matters much. A developer familiar with some lispy language (and perhaps functional programming) should be able to quickly pickup any other lispy language. And the developers that make the most money have probably used a lot of programming languages, with different paradigms.

If I knew the answer to that question I'd probably have a very different job than the one I have. :)
