Who is the highest paid opera singer in world today?

As of my most recent update in September 2021, the highest paid opera singer in the world is Jonas Kaufmann. He is a German operatic tenor who has performed in leading roles at the Metropolitan Opera in New York City, the Royal Opera House in London, and the Bavarian State Opera in Munich. Kaufmann has also performed in concert with some of the world's most prestigious orchestras, including the Berlin Philharmonic and the Vienna Philharmonic. His estimated annual earnings are approximately $10 million, making him one of the highest-paid classical musicians in the world.

It's important to note that the earnings of opera singers, like those of many performing artists, can vary greatly depending on factors such as their popularity, the number of performances they give, and the size of the theater or concert hall where they perform. The figures provided are estimates and may have changed since my most recent update.
