OnlyFans Owner Leonid Radvinsky Dies at 43 After Battle with Cancer

​The tech and creator world is in mourning following the announcement that Leonid "Leo" Radvinsky, the billionaire owner of OnlyFans, has passed away. The company confirmed in a statement on Monday, March 23, 2026, that Radvinsky died peacefully at the age of 43.

​Radvinsky, a Ukrainian-American entrepreneur, was the driving force behind the global expansion of the subscription-based platform after acquiring it in 2018.

Leonid Radvinsky: Cause of Death

​According to the official statement from an OnlyFans spokesperson, the cause of death was a long and private battle with cancer.

​"Leo passed away peacefully after a long battle with cancer. His family has requested privacy at this difficult time," the company stated.



​While the specific cancer type was never publicly disclosed by Radvinsky during his life, he was a known donor to several medical research institutions, including the Memorial Sloan Kettering Cancer Center.

Net Worth and Legacy

​At the time of his death in March 2026, Leonid Radvinsky’s net worth was estimated by Forbes to be approximately $4.7 billion.

​His wealth was largely generated through Fenix International Ltd, the parent company of OnlyFans. Under his leadership, the platform grew from a niche site to a cultural phenomenon, boasting:

  • ​Over 300 million registered users.
  • ​More than 4 million content creators.
  • ​Annual revenues exceeding $1 billion.

Personal Life: Wife and Family

​Radvinsky was famously reclusive, rarely appearing in the media. He was married to Katie Chudnovsky, a fellow entrepreneur. The couple kept their personal life and children out of the spotlight, a practice they maintained even through his health struggles.

The Future of OnlyFans

​Following his passing, questions have been raised about the ownership of the platform. Since 2024, Radvinsky’s shares have been held in the LR Fenix Trust. The day-to-day operations of the company remain under the leadership of current CEO Keily Blair, who took over from Amrapali Gan in late 2023.
