The Six Kings Slam is a high-profile men’s tennis exhibition event held in Riyadh, Saudi Arabia, as part of the country’s annual Riyadh Season. It was inaugurated in October 2024 and features a small field of six of the world’s top male players, often including the reigning Grand Slam champions and top-ranked competitors. The tournament is notable for offering an unprecedented prize purse for an exhibition, with the winner of the inaugural edition taking home $6 million.
There are no ranking points or head-to-head records at stake, just pure tennis showtime. Though unofficial, the Riyadh tournament has quickly become a magnet for top players thanks to its massive payouts: Each participant banks £1.1m ($1.5m), while the winner pockets an extra £3.4m ($4.5m), taking home a staggering £4.5m
