Novak Djokovic is already the only tennis player in ATP or WTA history to surpass $140 million and $150 million in career prize money, and he’s about to break yet another barrier.

By winning his first round robin match at the ATP Finals on Monday, defeating Stefanos Tsitsipas, 6-4, 7-6 (4), Djokovic guaranteed he will surpass $160 million in career prize money next Monday.

The Serb currently has $159,951,008. Just by taking the court for his first match at the ATP Finals he earned a $160,000 participation fee, and by winning it he earned $383,300—so even if he were to stop here, he would already be well past the $160 million mark.

Players can earn up to $4,740,300 if they win the season-ending championships undefeated, so Djokovic could leave Turin almost halfway to the $170 million mark should he do that.

  • $159,951,008: Novak Djokovic
