The Six Kings Slam has returned to Riyadh for its second edition, bringing together six of the world’s top tennis stars in a unique indoor exhibition format. From October 15 to 18, players will compete at the ANB Arena for a staggering $13.5 million prize pool, making it the most lucrative tournament in tennis. Each participant receives a $1.5 million appearance fee, while the winner takes home $6 million—over $800,000 more than Carlos Alcaraz earned by winning the US Open.
Unlike traditional ATP events, the Six Kings Slam does not offer ranking points. Its appeal lies in the elite field, knockout format, and global streaming via Netflix.
Why Djokovic and Alcaraz are seeded
Despite winning the Australian Open and Wimbledon in 2025 and being the defending champion, Jannik Sinner was not granted a seeded position. Organizers based seeding on career Grand Slam totals, giving Novak Djokovic (24 titles) and Carlos Alcaraz (6 titles) direct entry into the semifinals.
Sinner must first face Stefanos Tsitsipas, who replaced the injured Jack Draper. The Italian leads their indoor head-to-head, having won in Rotterdam and the ATP Finals in 2023, but trails 3–6 overall. Their most recent clash in Monte Carlo 2024 saw Tsitsipas win in three sets.
