Jannik Sinner successfully defended his Six Kings Slam 2025 crown, cruising to a straight-sets victory over Carlos Alcaraz (6-2, 6-4). The win secures him a massive $6 million payday, combining the $4.5 million winner’s share with his $1.5 million appearance fee. It’s easily the biggest haul of Sinner’s career and pushes his 2025 earnings to an eye-watering $18 million, up from around $12 million before Riyadh.

Meanwhile, Alcaraz has already won eight titles from ten finals this season, including the French Open and US Open, pushing his annual earnings past $16 million. And now with the addition of the appearance fee, he has earned $17.5 million.

The high-profile event, broadcast live on Netflix, brought together six of the world’s best players in a format that offered neither ranking points nor head-to-head records, but plenty of intrigue and financial reward.

Total Prize Money breakdown of the Six Kings Slam 2025

Each participant in the three-day tournament received a $1.5 million appearance fee, while the eventual champion pocketed $4.5 million (plus the appearance fee, making it $6 million). Thus, the total prize pool of the Six King Slam is $13.5 million and is distributed as explained above.

The Six Kings Slam winner’s share surpasses the $5 million earned by the US Open champion this year, highlighting Saudi Arabia’s growing influence in the sport. In comparison, winners at the other 2025 majors took home $4 million at Wimbledon, $2.9 million at Roland Garros, and $2.3 million at the Australian Open, emphasizing just how monumental the Riyadh payout is.

The knockout-style exhibition saw Stefanos Tsitsipas and Alexander Zverev exit after single-match defeats in the quarterfinals, with Novak Djokovic and Taylor Fritz contesting the third-place play-off. The latter ended abruptly when Djokovic retired after the first set due to a left leg injury.

For Zverev, even defeat came with a windfall. He earned $1.5 million for his 59-minute loss to Fritz, meaning he was paid roughly $25,000 per minute. This was about $250,000 more than he received for reaching the Australian Open final in January.

I’m an academic turned sports writer from Raipur, India, specializing in the NFL, MMA, and tennis at The Playoffs. I previously wrote for Sportskeeda and hold a B.A. and M.A. in History. My journey into sports media began far from the field, rooted in the arts and sciences. Funny enough, I didn’t grow up a sports fan; I used to see it all as just noise. But a fateful writing job introduced me to the world of sports, and what began as a gig quickly became a passion. I understood those voices aren’t noise; they’re emotions of true sports fans, and now I am one of them, writing with the same energy I once questioned.
