A Champion On and Off the Court

For millions around the world, Billie Jean King is synonymous with the fight for equality in sports. A 39-time Grand Slam champion, she dominated tennis during her playing career. Yet her greatest legacy may be the work she did away from the baseline—advocating for gender equality, racial justice, and LGBTQ+ rights at a time when speaking out carried enormous professional and personal risk. King’s journey from a working-class girl in Long Beach, California, to a global icon of social justice offers a blueprint for using athletic visibility as a platform for meaningful change. This article explores how King specifically advanced LGBTQ+ rights in sports, from her historic public coming out to her role in shaping inclusive policies and inspiring a new generation of athletes.

Early Life and the Rise of an Activist

Billie Jean Moffitt was born in 1943 in Long Beach, California. Her parents, Bill and Betty Moffitt, were both athletes—her father a firefighter and her mother a homemaker—but the family had no connection to tennis. King discovered the sport at age 11 on public courts in Long Beach, and her talent blossomed quickly. By her late teens, she was competing in junior tournaments and won the Wimbledon women's doubles title in 1961 with Karen Hantze Susman. The early 1960s saw her rise through the amateur ranks, and she claimed her first Wimbledon singles title in 1966.

What distinguished King from many of her peers was her willingness to question the status quo. Even as a young player, she was acutely aware of the disparities between male and female athletes. In the late 1960s, prize money for women's events was a fraction of what men received. For instance, at the Italian Open in 1968, the men’s champion earned $12,000 while the women’s champion earned just $600. King could not accept such inequity. She began organizing boycotts and quietly rallying other players to demand equal treatment. In 1970, she helped found the Virginia Slims Circuit, a separate professional tour for women that eventually led to the creation of the Women’s Tennis Association (WTA) in 1973. Her leadership during this period established her as an activist long before she ever publicly addressed LGBTQ+ issues.

The Battle of the Sexes and Its Broader Meaning

King’s famous 1973 “Battle of the Sexes” match against Bobby Riggs served as a watershed moment for gender equality. The match, watched by an estimated 90 million people worldwide, was not just about tennis—it was a symbolic contest over women’s capabilities. King’s decisive victory (6–4, 6–3, 6–3) shattered myths about female athletic inferiority and gave mainstream visibility to the women’s rights movement. Yet King understood that the fight for equality extended beyond gender. As she later wrote in her memoir, All In, “The Battle of the Sexes was about respect. But respect is not just about women. It’s about everyone—regardless of race, sexual orientation, or identity.”

This understanding would shape her subsequent work. Even as she fought for equal prize money in the 1970s, King was quietly forming friendships and alliances that would later inform her LGBTQ+ advocacy. She was aware of the discrimination faced by gay and lesbian athletes, but the climate of the era forced many—including herself—to stay closeted. “I knew that if I came out, I would lose endorsements, and that might hurt the fight for women’s tennis,” King later reflected. “I made a calculation. I think it was the right one for the time, but it was painful.”

The Courage to Come Out

A Landmark Revelation in 1981

In 1981, King’s life changed irrevocably when a former female lover, Marilyn Barnett, filed a palimony lawsuit against her. The legal action forced King to publicly confront her sexuality. On May 8, 1981, King held a press conference where she acknowledged the relationship, effectively coming out as gay. She later stated, “I didn’t want to come out that way. But I was not going to lie. I have nothing to hide.”

The reaction was swift and often harsh. King lost an estimated $1.5 million in endorsements almost overnight. Sponsors like Gillette, Marlboro, and Wilson distanced themselves from her. The tennis establishment was uncomfortable, and many major tournaments chose not to schedule her matches on center court. Yet King refused to retreat. In the months following her public statement, she continued playing competitive tennis and speaking out against discrimination.

The Impact of a Public Figure

At the time, King was perhaps the most famous athlete in the world to come out. Only a handful of others—such as NFL player David Kopay, who came out in 1975—had preceded her, and none with the same level of mainstream recognition. King’s openness forced the sports media to cover homosexuality as a legitimate topic. “She normalized a conversation that had been taboo,” notes historian Dr. Susan K. Cahn in her research on sexuality in sports. “By refusing to hide, Billie Jean made it possible for countless others to consider living openly.”

King’s coming out also created a template for how athletes could navigate the intersection of their public and private lives. She did not make her sexual orientation the central theme of her career, but she refused to let it be a source of shame. By simply continuing to compete and engage with fans as she always had, she demonstrated that being gay was not an impediment to excellence in sports.

Advocacy for LGBTQ+ Rights in Sports and Society

Pride, Speaking Engagements, and Visibility

Throughout the 1980s and beyond, King became a fixture at Pride parades, LGBTQ+ galas, and human rights events. She used her speaking platform to argue that sports must be a welcoming space for everyone. “I want every kid who picks up a racket or a ball to feel they can be who they are,” she often stated. King’s visibility was especially important in the AIDS crisis era, when homophobia and stigma were rampant. She visited hospitals, raised funds for research, and spoke out against the discrimination faced by people with HIV/AIDS.

King also lent her name and time to organizations working for LGBTQ+ equality, including the Human Rights Campaign, GLAAD, and the National Center for Lesbian Rights. She served as an honorary chair for the 1993 March on Washington for Lesbian, Gay, and Bi Equal Rights and Liberation. These public gestures may seem modest by today’s standards, but in the 1980s and 1990s, having a mainstream sports icon openly associate with LGBTQ+ causes was revolutionary.

Policy Changes and Institutional Impact

King’s influence extended beyond symbolic appearances. She worked behind the scenes to push sports organizations to adopt nondiscrimination policies. In 1985, she helped shape the United States Tennis Association’s (USTA) first policy statement on sexual orientation, which affirmed that the organization would not discriminate based on “race, color, religion, sex, or sexual orientation.” It was one of the first such policies in professional sports.

King also lobbied the International Tennis Federation (ITF) and the Women’s Tennis Association to ensure their anti-discrimination policies explicitly covered sexual orientation and gender identity. She advocated for transgender inclusion long before it became a mainstream issue. In 2019, the WTA updated its medical and safety guidelines to include specific protections for transgender athletes, a move that King publicly supported.

Off the tennis court, King played a role in the creation of the Billie Jean King Leadership Initiative (BJKLI), which she co-founded in 2014. The initiative focuses on diversity, equity, and inclusion in the workplace, with particular attention to LGBTQ+ issues. The BJKLI works with corporations, universities, and nonprofits to develop strategies for creating inclusive cultures.

King’s influence reached the highest levels of the U.S. legal system. In 2020, she was part of a coalition of athletes and advocates who filed an amicus brief in Bostock v. Clayton County, Georgia, the landmark Supreme Court case that established that Title VII of the Civil Rights Act protects employees from discrimination based on sexual orientation or gender identity. King’s brief argued that discrimination against LGBTQ+ people in sports and other workplaces was incompatible with the nation’s founding principles. The Court’s 6–3 decision in favor of the employees was a significant victory, and King called it “a step forward for all of us.”

Intersectional Advocacy: Gender, Race, and Sexuality

King understood early that discrimination does not exist in isolated categories. Her advocacy for LGBTQ+ rights has always been intertwined with her work for gender equality and racial justice. In the 1970s, she was an early supporter of the Women’s Equal Rights Amendment and spoke out against racism in tennis. She frequently credited Black tennis pioneers like Althea Gibson and Arthur Ashe with inspiring her own activism.

This intersectional approach informed King’s work with LGBTQ+ athletes of color. She partnered with organizations like the National Center for Lesbian Rights to support athletes who faced multiple forms of discrimination (e.g., Black lesbian athletes or transgender women of color). King has repeatedly stated that “the fight for equality is indivisible—you can’t separate gender, race, or sexuality. They are all part of the same struggle.”

Legacy: Changing the Landscape of Sports

Inspiring a Generation of LGBTQ+ Athletes

King’s courage did more than change policies—it changed lives. Countless athletes have cited her as a pivotal influence in their own decisions to live openly. Tennis star Martina Navratilova, who came out in 1981 shortly after King, has called her “the greatest pioneer for LGBTQ+ rights in sports.” In recent years, a wave of openly gay athletes across multiple sports—from soccer’s Megan Rapinoe to basketball’s Sue Bird to figure skater Adam Rippon—have credited King with paving the way.

King has also been a vocal supporter of transgender athletes, particularly as debates over transgender participation in sports have intensified. She has consistently argued that inclusion is a fundamental value, stating, “We have to stand up and make sure that everyone, regardless of who they are, gets to play.” Her stance has sometimes drawn criticism, but King does not waver. She points to her own experience as a woman who was told she didn’t belong in tennis as evidence that exclusion harms everyone.

Institutional Recognition and Honors

King’s contributions have been recognized by major sports organizations and LGBTQ+ advocacy groups. In 2009, President Barack Obama awarded her the Presidential Medal of Freedom, the nation’s highest civilian honor, citing her activism for “gender equality and human rights for all people.” In 2021, the USTA dedicated a statue of King at the Billie Jean King National Tennis Center in Flushing, New York—the first statue of a woman on the grounds of the U.S. Open. The statue depicts King in motion, racket in hand, with her backhand ready to strike. It is a fitting tribute to a woman who transformed the sport both on and off the court.

In 2023, the International Tennis Hall of Fame inducted King for a second time—this time in a special category recognizing her humanitarian work. She has also received the Arthur Ashe Courage Award and the National Gay and Lesbian Hall of Fame recognition.

Challenges and Continuing the Fight

Despite the progress, King is the first to acknowledge that the fight is far from over. LGBTQ+ athletes still face discrimination, harassment, and exclusion—especially transgender athletes, who are currently the target of legislative attacks in multiple U.S. states. King has called for sports organizations to adopt uniform inclusive policies and has urged professional leagues to speak out against anti-LGBTQ+ legislation. “You can’t be neutral on a moving train,” she has said. “Silence is complicity.”

King has also been active in efforts to address ongoing disparities in funding for women’s sports and in safeguarding LGBTQ+ youth players. She supports the work of the Out on the Fields initiative, which studies homophobia in sports and develops educational resources. “The next generation has to feel safe,” King says. “They have to know that the locker room and the field belong to them, too.”

Conclusion

Billie Jean King’s advocacy for LGBTQ+ rights in sports is a testament to the power of courage, persistence, and strategic action. From her groundbreaking coming out in 1981 to her ongoing work for transgender inclusion, she has used her platform to challenge the notion that sports belong only to certain people. Her legacy is visible in the athletes who now live openly, in the policies that protect them, and in the growing recognition that inclusion enhances the game for everyone. As King herself often says, “You have to see it to be it.” By refusing to hide, she helped millions of people see a future in which they, too, could belong.
