Jannik Sinner's victory over Carlos Alcaraz at the Six Kings Slam event this past weekend saw him win the exhibition tournament for a successive year.
The Italian took down the world No. 1 6-2 6-4 in the final round in Riyadh, Saudi Arabia on Saturday (October 18), just weeks after losing to him in the US Open final.
Sinner has now won both editions of the exhibition event, which has attracted some of the world's top male tennis players due to the lucrative prize money available.
This year's two finalists along with Novak Djokovic, Alexander Zverev, Taylor Fritz and Stefanos Tsitsipas all received $1.5m for participating, while Sinner pocketed an additional $4.5m for securing the title.
The $6m total prize money Sinner took home for winning the four-day event in Riyadh is the highest prize fee in tennis currently.

Following his win at the 2025 Six Kings Slam, Sinner has now pocketed $18.4m for competing on the court this year.
The money that the world No. 2 has earned comes despite him missing three months of the season due to serving a World Anti-Doping Agency (WADA) suspension.
In addition to competing at the Six Kings Slam, the four-time major winner has entered nine ATP Tour-level events this year.
Out of the $12.4m that Sinner has earned from competitive events in 2025, the majority has come from his Grand Slam appearances.
Winning a second Australian Open title earned him $2.1m, while his first Wimbledon title saw him pick up $4m there.
Runner-up finishes at the French Open and US Open earned him $1.4m and $2.5m, respectively.
Overall, Sinner has earned a whopping $61.6m in career prize money to date from participation in both competitive and exhibition events.
