Tennis Antitrust Lawsuit Survives Dismissal Attempts by ATP, WTA and Grand Slams
A major legal battle over the future of professional tennis has taken another important step after a U.S. federal judge refused attempts by the ATP, WTA and three Grand Slam tournaments to have an antitrust lawsuit thrown out.
The case was brought by the Professional Tennis Players Association (PTPA) and a group of current and former players. The lawsuit argues that the organizations controlling professional tennis have created a system that restricts competition, limits players' earning opportunities and places excessive demands on their careers.
Judge Margaret M. Garnett of the U.S. District Court for the Southern District of New York rejected six separate motions connected to the case in a 66-page decision issued on September 30, 2026. The ruling means the lawsuit can continue into the discovery phase rather than being dismissed at the early stage.
The decision does not mean the players have won the lawsuit. Instead, the judge determined that the allegations were sufficiently plausible to move forward. At the dismissal stage, the court generally has to treat the allegations in the complaint as true for the purpose of deciding whether the case can proceed.
The PTPA claims that professional tennis operates through interconnected structures involving the ATP, WTA and Grand Slam tournaments. According to the lawsuit, those structures restrict competition for players' services and affect areas such as prize money, rankings, tournament scheduling and player freedom.
One of the central arguments concerns player compensation. The PTPA says tennis players receive a significantly smaller share of the sport's revenues than athletes in several other major professional sports. It also argues that lower-ranked players can struggle financially because travel, coaching and other professional expenses can consume much of their tournament earnings.
The lawsuit also challenges the structure of the tennis calendar. Players are independent contractors rather than traditional employees, yet the PTPA argues that mandatory events, ranking requirements and penalties can limit their ability to decide when and where they compete.
Player welfare is another major part of the case. The PTPA argues that an extremely demanding calendar can contribute to physical problems while simultaneously making it difficult for players to take sufficient breaks without suffering ranking or financial consequences.
The Grand Slam tournaments attempted to distance themselves from the allegations, arguing that the complaint did not establish a sufficient connection between the individual majors and the alleged conspiracy. However, Judge Garnett identified several agreements and governing structures that, at this stage, were enough for the claims involving the French Open, Wimbledon and U.S. Open to remain in the case.
The ATP also attempted to have the men's claims moved to Delaware based on a provision in its bylaws. The judge rejected that request, reasoning that separating the case could result in essentially the same allegations being litigated in different courts and could create the possibility of conflicting decisions.
The WTA and U.S. Tennis Association also sought arbitration in an effort to move the dispute away from the federal court proceedings. Those attempts were rejected as well. The PTPA said the ruling allows the case to remain together rather than being divided, relocated or sent into private arbitration.
The composition of the case has changed since it was first filed in March 2025. The original lawsuit named the ATP, WTA, International Tennis Federation and International Tennis Integrity Agency as defendants while describing the four Grand Slams as co-conspirators. Later, the PTPA removed the ITF and ITIA and formally added the Grand Slam organizations as defendants.
Tennis Australia, the organization behind the Australian Open, eventually reached an undisclosed settlement with the PTPA and was removed from the case. The remaining Grand Slam defendants are the organizations behind the French Open, Wimbledon and U.S. Open.
The lawsuit has also continued despite Novak Djokovic's departure from the PTPA. Djokovic, who helped establish the organization alongside Vasek Pospisil in 2020, announced in January 2026 that he was leaving because of concerns about transparency, governance and the way his voice and image were being represented. His departure does not automatically end the legal action because the lawsuit is being pursued collectively by the PTPA and named players.
For the tennis world, the next stage could be particularly significant. With the dismissal attempts unsuccessful, the parties can now face discovery, a process in which evidence and internal documents can become part of the legal proceedings. The case could eventually lead to settlement negotiations, further court battles or a trial.
The PTPA is seeking changes to the way professional tennis is structured and compensated, while the governing bodies have strongly rejected the allegations. The ATP previously described the lawsuit as without merit, while the WTA also defended its record and said the claims were baseless.
For now, the most important development is that the lawsuit has survived its first major legal challenge. The court has not ruled that the PTPA's allegations are proven, but it has determined that they are substantial enough to deserve further examination.
That could make the coming stages of the case one of the most consequential legal battles in modern professional tennis, with the potential to influence how tournaments are organized, how players are compensated and how much control athletes have over their own careers.
