Six Kings Slam: Inside Tennis’s Richest Exhibition Tournament in Riyadh

The Six Kings Slam rewrote the financial rulebook of professional tennis the moment it was announced. Staged in Riyadh as the crown jewel of the annual Riyadh Season entertainment festival, this six-player exhibition knockout tournament offered a winner’s purse of $6 million — a figure that eclipsed the champion’s prize at every Grand Slam on the calendar. Two editions have now been played, both won by Italian world number one Jannik Sinner, and the event has become the single most lucrative date in any tennis player’s diary.

What makes the Six Kings Slam remarkable is not merely the money, although the money alone would justify the attention. It is the deliberate curation of a field that reads like a Mount Rushmore of the modern game: Novak Djokovic, Rafael Nadal, Carlos Alcaraz, Jannik Sinner, and a rotating cast of the sport’s next tier of stars. The tournament has become Saudi Arabia’s definitive statement that Riyadh intends to stand alongside Melbourne, Paris, London, and New York as a capital of world tennis — even if the event carries no ATP ranking points.

Origins and Concept

The Six Kings Slam was conceived by Saudi Arabia’s General Entertainment Authority as part of the broader Riyadh Season, an annual months-long entertainment and sports festival that has hosted everything from boxing mega-fights to Formula E races. Tennis was a natural addition. Saudi Arabia had already staged the Diriyah Tennis Cup in 2019 and 2022, the Next Gen ATP Finals in Jeddah since 2023, and had inked a three-year deal to host the WTA Finals in Riyadh beginning in 2024. The Six Kings Slam represented an escalation — not just another tournament, but the most expensive tennis event ever created.

The format is deliberately simple and television-friendly. Six players compete in a single-elimination knockout bracket over three days, with two quarterfinals on the opening day, two semifinals on the second day, and a third-place match followed by the final on the closing day. All matches are best of three sets. Two players receive first-round byes, typically the two highest-ranked or most marketable competitors in the field. A rest day is built into the schedule between the second and third days of play, in compliance with ATP regulations that prohibit players from competing in exhibition matches on three consecutive days.

Production is handled by IMG, the global sports management and media company, ensuring broadcast-quality coverage that rivals any ATP Tour event. The inaugural edition in 2024 was broadcast by DAZN internationally and T2 in the United States. By the second edition in 2025, Netflix had acquired exclusive global rights — a landmark deal that placed the Six Kings Slam alongside the streaming giant’s growing portfolio of live sports content, including its earlier Netflix Slam featuring Nadal and Alcaraz.

Prize Money: Redefining the Economics of Tennis

Every player who steps onto the court at the Six Kings Slam receives a guaranteed appearance fee of $1.5 million, regardless of result. The winner collects an additional $4.5 million on top of that guarantee, bringing the total winner’s haul to $6 million. The total prize pool across all six players is $15 million.

To appreciate the magnitude of these figures, consider the comparisons. When Sinner won the inaugural Six Kings Slam in October 2024, his $6 million prize nearly doubled the $3.8 million earned by a Grand Slam champion that year. By the 2025 edition, the US Open had raised its champion’s prize to $5 million — still $1 million less than what Sinner earned in a three-day exhibition. The Six Kings Slam winner’s purse also exceeded Djokovic’s previous record prize of $4,740,300, earned at the 2022 ATP Finals in Turin, which at the time represented the largest single payout in tennis history.

The per-minute earnings tell an even more striking story. In the 2025 edition, Alexander Zverev collected his $1.5 million guarantee after spending just 58 minutes on court before losing in the quarterfinals — earning $25,862 per minute, or $431 per second. Sinner, who played three matches totaling 212 minutes, earned $28,302 per minute and $472 per second for his $6 million haul. Even for a sport accustomed to seven-figure paydays, these are numbers without precedent.

The guaranteed appearance fee structure means that even the first-round losers leave Riyadh with $1.5 million for approximately one hour of work. This creates a compelling incentive for the world’s best players to participate despite the event carrying no ranking points and the grueling nature of the late-season schedule. As both Sinner and Taylor Fritz publicly acknowledged, the $6 million prize money “adds genuine motivation” even though the Six Kings Slam is technically classified as an exhibition.

The 2024 Inaugural Edition

The first Six Kings Slam took place on October 16-17 and 19, 2024, with a rest day on October 18. The field was curated for maximum star power and narrative resonance: Jannik Sinner (seeded first), Carlos Alcaraz (second), Novak Djokovic (third), Rafael Nadal (fourth), Holger Rune (fifth), and Daniil Medvedev (sixth). Djokovic and Nadal, as the two highest seeds after Sinner and Alcaraz, received first-round byes.

The quarterfinals set the tone for Sinner’s dominance. He dismantled Medvedev 6-0, 6-3 in a performance that left little doubt about who the favorite would be. Alcaraz handled Rune with professional efficiency, winning 6-4, 6-2. Both matches were clinical rather than dramatic, the kind of one-sided affairs that occasionally happen when elite players meet a half-tier below them on a neutral court with nothing but money on the line.

The semifinals raised the stakes. Sinner defeated Djokovic to advance to the final, while Alcaraz overcame Nadal in what would prove to be one of the last competitive matches of the Spaniard’s career. The semifinal defeats set up a third-place match between Djokovic and Nadal — the 61st all-time head-to-head meeting between the two most prolific rivals in tennis history. Djokovic won 6-2, 7-6(5) in what was widely described as a farewell match, with Nadal having announced his retirement from professional tennis at the end of the 2024 season. In recognition of his legacy, organizers presented Nadal with a life-size replica solid gold racket honoring his career.

The final between Sinner and Alcaraz delivered the competitive drama the earlier rounds had lacked. Alcaraz took the first set in a tiebreak, 7-6(5), seizing the initiative with the kind of fearless shot-making that had already earned him four Grand Slam titles. But Sinner, unflappable and methodical, responded with back-to-back set victories, 6-3, 6-3, to claim the inaugural title and the largest single prize in tennis history. Sinner’s trophy was a life-size replica tennis racket made of 24-karat solid gold, weighing four kilograms.

The 2025 Second Edition

The second Six Kings Slam ran from October 15-16 and 18, 2025, maintaining the same three-day format with a rest day on October 17. The field reflected both continuity and change: Sinner and Alcaraz returned as the top draws, joined by Taylor Fritz, Novak Djokovic, Alexander Zverev, and Stefanos Tsitsipas. Tsitsipas was a late replacement for Jack Draper, who withdrew due to a season-ending arm injury. This time, Alcaraz and Djokovic received first-round byes.

Fritz dispatched Zverev 6-3, 6-4 in the quarterfinals, while Sinner handled Tsitsipas 6-2, 6-3. The semifinals saw Alcaraz reassert his clay-court artistry on a hard court, beating Fritz 6-4, 6-2, while Sinner once again proved too strong for Djokovic, winning 6-4, 6-2.

The third-place match went to Fritz over Djokovic via tiebreak, while the final was a repeat of the 2024 championship. This time, Sinner left no room for doubt, winning 6-2, 6-4 in straight sets to successfully defend his title. The comprehensive nature of the victory — Sinner dropped just one set across six matches over two editions — established him as the tournament’s defining champion.

Netflix’s exclusive global broadcast of the 2025 edition marked a significant shift in the event’s media strategy. The deal gave Netflix subscribers access at no additional cost — no pay-per-view, no premium tier — placing the Six Kings Slam in front of Netflix’s global subscriber base of over 300 million households. For Saudi organizers, the Netflix partnership represented something potentially more valuable than broadcast revenue: cultural legitimacy and mainstream global visibility.

The Players and Their Motivations

The Six Kings Slam occupies an unusual space in the tennis calendar. It is not an official tournament. It awards no ranking points. It counts toward no season statistics. And yet the world’s best players not only participate but, by their own admission, compete with genuine intensity.

The financial incentive is obvious — $1.5 million guaranteed, with the possibility of $6 million — but players have pointed to other motivations as well. The field is small enough that every match feels significant. The format rewards aggressive, attacking tennis. And the event’s position in October, between the late-season hard-court swing and the ATP Finals in November, means players arrive in peak form.

There is also an element of professional pride. The field is curated, not open. Being invited to the Six Kings Slam is itself a mark of status, an acknowledgment that a player belongs to the sport’s absolute elite. When Jack Draper was initially selected for the 2025 edition, it represented a coronation of sorts — recognition that the young Briton had arrived among tennis’s inner circle.

Critics have noted a tension in the players’ participation. Several competitors, including Alcaraz, have publicly criticized the ATP and WTA’s packed schedules, citing burnout and the physical toll of year-round competition. Yet those same players willingly add the Six Kings Slam to their calendars, drawn by appearance fees that dwarf their earnings from mandatory tour events. The counterargument is straightforward: players have limited earning windows, and the Six Kings Slam concentrates more prize money into three days than most tournaments offer across an entire week.

Cumulative Exhibition Earnings

The Six Kings Slam has accelerated the growth of the exhibition market, with cumulative earnings for top players reaching remarkable levels. Carlos Alcaraz is estimated to have earned over $10 million from exhibition events since the start of 2024, across the Six Kings Slam (both editions), the Netflix Slam in March 2024, and other appearances. These figures rival or exceed his official tour prize money over the same period, raising questions about the financial incentive structure of professional tennis.

The broader trend is unmistakable: Saudi Arabia has become the highest-paying exhibition destination in tennis history. The appearance fees, winner’s prizes, and ancillary benefits (luxury hospitality, private flights, and, in Nadal’s case, a solid gold racket) create a financial package that no other market can match. This has implications not only for the Six Kings Slam but for the entire ecosystem of professional tennis, as the sport grapples with the tension between official tour obligations and the lure of off-tour riches.

Venue and Atmosphere

The Six Kings Slam is staged in Riyadh as part of the broader Riyadh Season festival, which transforms Saudi Arabia’s capital into a hub of entertainment, sport, and culture. The exact venue has varied, but the tournament benefits from purpose-built or adapted arenas designed to create an intimate, high-energy atmosphere.

The Riyadh Season context matters. The festival draws millions of visitors to the city each year, and tennis events are positioned alongside concerts, theatrical productions, and other sporting events. This creates a crossover audience — attendees who might attend the Six Kings Slam as part of a broader entertainment experience rather than as dedicated tennis fans. For Saudi organizers, this is a feature, not a bug. The goal is not merely to attract existing tennis audiences but to create new ones.

The atmosphere inside the arena has been described by players as electric, particularly for the finals. Sinner noted after his 2024 victory that the crowd was engaged and vocal, a contrast to the attendance concerns that plagued the WTA Finals held in Riyadh just weeks later. The Six Kings Slam benefits from its boutique format — three days, six players, guaranteed star power — which creates a sense of exclusivity and event-ness that longer, drawn-out tournaments sometimes struggle to maintain.

Broadcast and Media Impact

The Six Kings Slam’s media trajectory tells a story of rapid escalation. The 2024 inaugural edition was broadcast by DAZN internationally and T2 in the United States — credible platforms but not mainstream household names in every market. By 2025, the event had secured exclusive global rights with Netflix, one of the most significant broadcast deals in tennis history.

The Netflix deal placed the Six Kings Slam alongside Formula 1’s “Drive to Survive,” golf’s “Full Swing,” and the platform’s earlier “Break Point” tennis docuseries as part of a broader strategy to own live and near-live sports content. For the Six Kings Slam, the Netflix partnership offered access to a global audience that traditional sports broadcasters cannot match. For Netflix, the tournament offered premium live content with guaranteed star power — Sinner versus Alcaraz is a reliable draw regardless of the tournament’s official status.

The production quality, handled by IMG, has been consistently high. Camera angles, player microphone access, and pre-match features have drawn favorable comparisons to Grand Slam coverage. The three-day format also suits the streaming model, offering a concentrated burst of content rather than the two-week sprawl of a major championship.

Significance for Saudi Arabian Tennis

The Six Kings Slam is the most visible component of Saudi Arabia’s broader investment in tennis, which includes the PIF’s naming partnership with both the ATP and WTA rankings, sponsorship of Masters 1000 events globally, the WTA Finals hosting deal, the Next Gen ATP Finals in Jeddah, and the forthcoming ATP Masters 1000 tournament in Saudi Arabia from 2028 — the first expansion of the Masters 1000 category in the ATP Tour’s 35-year history.

Together, these investments position Saudi Arabia as the single most influential new force in professional tennis. The Six Kings Slam serves a specific purpose within this portfolio: it is the spectacle, the headline-grabber, the event that puts Riyadh on the front page of every sports section in the world. While the ATP Masters 1000 tournament will eventually provide official ranking-point legitimacy, the Six Kings Slam provides something arguably more valuable in the short term — cultural cachet and global name recognition.

The tournament also aligns with Saudi Arabia’s Vision 2030 strategic plan, which aims to diversify the Kingdom’s economy away from oil dependence and position Saudi Arabia as a global destination for entertainment, tourism, and sport. The Six Kings Slam contributes to all three objectives simultaneously: it attracts international visitors, generates global media coverage, and establishes Riyadh as a credible host city for premium sporting events.

Rafael Nadal’s role as ambassador to the Saudi Tennis Federation adds a layer of institutional endorsement. Having one of the most accomplished and respected athletes in history serve as the face of Saudi tennis lends credibility that money alone cannot buy. Nadal’s emotional farewell at the 2024 Six Kings Slam — his final singles match against long-time rival Djokovic — provided a genuinely historic moment that transcended the exhibition format.

Criticism and Controversy

The Six Kings Slam has not been immune to criticism. The most persistent objection is the broader charge of sportswashing — the accusation that Saudi Arabia uses sports investments to improve its international reputation and distract from its human rights record, including concerns about the treatment of women, political dissidents, labor rights, and the 2018 murder of journalist Jamal Khashoggi.

Tennis-specific criticisms have focused on the impact of lucrative exhibitions on the official tour calendar. The ATP and WTA have spent decades building structured competitive seasons, and events like the Six Kings Slam risk undermining that architecture by offering far greater financial rewards outside the official framework. If a player can earn $6 million in three days at an exhibition, the argument goes, what incentive do they have to compete at a mandatory Masters 1000 event where the winner’s prize is a fraction of that amount?

The burnout question is closely related. Players who participate in the Six Kings Slam in mid-October are adding matches to an already-packed schedule just weeks before the ATP Finals in November. For a sport that has seen increasing player complaints about scheduling demands, the willingness to accept exhibition commitments complicates the narrative.

There is also a philosophical question about what the Six Kings Slam means for competitive integrity. Without ranking points, the tournament occupies a liminal space — more than a friendly but less than an official competition. Players insist they compete at full intensity, and the match results suggest this is largely true. But the absence of formal stakes means the Six Kings Slam will never produce the kind of career-defining moments that a Grand Slam final does, no matter how much money is on the line.

Looking Ahead

The Six Kings Slam has already established patterns that suggest longevity. The Sinner-Alcaraz rivalry provides a generational narrative that could anchor the event for years. The Netflix partnership provides a global distribution platform. And Saudi Arabia’s commitment to tennis — evidenced by the forthcoming ATP Masters 1000 event and continued WTA Finals hosting — suggests the Six Kings Slam will remain a priority for organizers.

Future editions may see format adjustments. There has been speculation about expanding the field to eight players, though the “six kings” branding imposes a natural constraint. The possibility of adding a women’s component has also been discussed, though no concrete plans have been announced. What seems certain is that the prize money will remain at or above current levels — anything less would undermine the event’s core identity as the richest tournament in tennis.

The Six Kings Slam has done something that few exhibition events in any sport have managed: it has made itself essential. Not essential in the competitive sense — it awards no points, counts toward no records, and determines no rankings — but essential in the cultural sense. When the world’s best tennis players gather in Riyadh each October, the sporting world pays attention. And that, ultimately, is exactly the point.
