Swiss tennis icon Martina Hingis remains one of the most recognizable names in the sport’s history—and her net worth in 2025 reflects both her enduring legacy and smart post-retirement moves. With a career that began in her early teens and a second wind in doubles success, Hingis has built an estimated net worth of $25 million to $30 million, according to financial reports and sports earnings databases.

Rising to prominence in the late 1990s, Hingis became the youngest Grand Slam champion of the Open Era, winning the Australian Open in 1997 at just 16 years old. She would go on to secure 5 Grand Slam singles titles, 13 Grand Slam doubles titles, and 7 mixed doubles titles, cementing her place in tennis history. Her dominance at such a young age earned her sponsorships and endorsements that were rare for teenage athletes at the time.

During her playing years, Hingis earned approximately $24 million in prize money, and millions more through endorsement deals with top-tier brands such as Fila, Rolex, Adidas, and Yonex. Even after initial retirement in the early 2000s due to injuries, her popularity remained intact, paving the way for a lucrative return to professional doubles and mixed doubles a few years later.

Off the court, Martina Hingis has remained financially active. She has invested in real estate in Switzerland, worked as a tennis coach and mentor, and appeared at global tennis exhibitions and events. Her presence in the tennis world continues, both as an ambassador for the sport and as a respected commentator in European broadcasts.

She has also lent her name to charitable efforts and youth tennis programs, helping promote the next generation of female athletes. Hingis is known for her sharp intellect and strategic approach, both on court and in managing her brand, which has helped maintain her financial success well after stepping away from the game.

With a career defined by brilliance, comebacks, and reinvention, Martina Hingis has shown that true champions don’t just win titles—they build legacies. Her wealth today reflects not just Grand Slam victories, but a lifetime of smart moves in the world of sport and beyond.

Roger Federer may have stepped away from competitive tennis, but his empire is only growing. Widely regarded as one of the greatest athletes of all time, the Swiss legend has built a financial portfolio that matches his stellar sports legacy. As of 2025, Roger Federer’s estimated net worth stands at a jaw-dropping $600 million to $700 million, according to multiple financial sources and endorsements tracking portals.

The 20-time Grand Slam champion retired from professional tennis in 2022, but unlike many athletes who fade from the spotlight, Federer’s brand has remained as powerful as ever. His wealth is the result of decades of prize money, a staggering endorsement portfolio, and savvy business investments that continue to yield results.

Federer’s on-court earnings from tournaments alone reached nearly $130 million, placing him among the highest-paid tennis players in ATP history. However, the bulk of his fortune has come from endorsements. He’s inked deals with luxury and lifestyle giants such as Rolex, Uniqlo, Credit Suisse, Wilson, LVMH, Mercedes-Benz, and Moët & Chandon. His switch from Nike to Uniqlo in 2018 alone reportedly earned him $300 million over ten years—a landmark deal in sports marketing.

In addition to his endorsement empire, Federer is also a shrewd investor. Through his firm Team8, he has backed ventures in sports management, media, and even skincare. He is also a part-owner of the Laver Cup, a tennis tournament he co-created, which has become one of the sport’s most successful post-season events.

The retired superstar also commands appearance fees and speaker engagements that rival A-list celebrities. In 2023, Federer made headlines for signing a deal with Louis Vuitton as a global ambassador, further solidifying his presence in the luxury lifestyle sector.

Federer’s brand extends beyond business and tennis. Known for his elegance, philanthropy, and composure, he also runs the Roger Federer Foundation, which has contributed millions towards education projects in Africa and his home country of Switzerland.

Despite his retirement, Federer remains a global figure in both sport and business. His net worth continues to climb, not just from past glory, but because of a keen understanding of branding, timing, and trust—qualities that made him a champion on and off the court.

Caroline Wozniacki, Denmark’s tennis icon and former world No. 1, has not only served up unforgettable moments on the court but has also built a financial legacy that ranks among the most impressive in women’s sports. As of 2025, Caroline Wozniacki’s estimated net worth stands at $40 million, according to Forbes and global sports finance outlets.

Wozniacki rose to international prominence in the late 2000s and became the first Scandinavian woman to reach world No. 1, holding the position for a total of 71 weeks. Her crowning moment came in 2018, when she finally captured her long-awaited Grand Slam title at the Australian Open, cementing her status among the sport’s elite.

Over the years, her career prize money exceeded $35 million, placing her among the top-earning female tennis players of all time. But it’s Wozniacki’s sharp eye for endorsements and business ventures that helped elevate her net worth even further.

She’s worked with Adidas, Rolex, Yonex, Babolat, Stella McCartney, and Lavazza, becoming a brand ambassador well beyond the sport. Her combination of athletic excellence, media appeal, and elegance made her a favorite for fashion campaigns and international sponsorships.

Since announcing her retirement in 2020, and later returning for selected tournaments in 2023–2024, Wozniacki has maintained a high public profile. She’s taken on broadcasting roles, appeared in sports documentaries, and even launched her own health and wellness initiatives aimed at empowering women through fitness.

She is also a strong advocate for rheumatoid arthritis awareness, using her platform to share her personal journey with the condition and inspire others facing health battles.

Married to former NBA star David Lee and a mother of two, Wozniacki has seamlessly balanced family life with her continuing influence in sport, fashion, and business.

Now at 34, Caroline Wozniacki continues to be a global role model, not just for aspiring tennis players but for athletes transitioning into life beyond competition. Her legacy is one of resilience, reinvention, and smart financial strategy—and her net worth is likely to keep growing as she expands her influence.
