OnlyFans Owner Leonid Radvinsky Dies of Cancer at 43 After Building Multi-Billion Empire

Leonid Radvinsky, the Ukrainian-American billionaire owner of the adult content subscription platform OnlyFans, died of cancer at the age of 43, the company announced on Monday, March 23, 2026. An OnlyFans spokesperson confirmed his death in a statement, saying he had passed away after a prolonged illness. „We are deeply saddened to announce the death of Leo Radvinsky. Leo passed away peacefully after a long battle with cancer. His family have requested privacy at this difficult time.” — OnlyFans spokesperson via Reuters Radvinsky, who was born in Odessa, Ukraine, and raised in the United States including in Chicago, was known for his extreme discretion and rarely gave interviews. He had also run Leo, a venture capital fund he founded in 2009 that focused on technology investments. According to Forbes, his net worth reached $4.7 billion at the time of his death, placing him 869th among the richest people in the world and 181st on the Forbes 400 list of the wealthiest Americans in 2025.

A £10,000 bet that became a multi-billion empire Radvinsky acquired Fenix International Limited, the parent company of OnlyFans, in 2018 and served as its director and majority shareholder. His initial investment at the time of acquisition was reported at 10,000 pounds. OnlyFans had been founded two years earlier, in 2016, by British entrepreneur Tim Stokely. Under Radvinsky's ownership, the platform's popularity surged dramatically during the COVID-19 pandemic, as lockdowns drove both creators and consumers online in large numbers. The platform transformed from a niche subscription service into a mainstream and globally recognized source of income for content creators. By 2024, the total number of creator accounts on the platform had grown by 13% to 4.6 million, according to company figures reported by Sky News.

Dividends of £522 million and a potential $8 billion sale The platform's financial performance generated substantial personal wealth for Radvinsky in the years before his death. In 2024 alone, he was paid £522 million in dividends, and by the beginning of 2025 he had collected a total of $1.8 billion in dividends from the company. OnlyFans reported $1.4 billion in revenue in 2024, with users spending $7.2 billion across the platform that year. Forbes calculated that the platform was generating approximately $1.9 million per day for Radvinsky in 2024. Reports indicated that Radvinsky had been in discussions to sell OnlyFans in a deal that would have valued the company at $8 billion, according to Forbes. In January 2026, Reuters had separately reported that OnlyFans was exploring the sale of a majority stake to investment firm Architect Capital in a deal valuing the company at approximately $5.5 billion, including debt.

A private man with a controversial early career Despite his enormous wealth, Radvinsky remained a deeply private figure throughout his life and was rarely seen in public or media settings. According to his personal website, his interests included programming, charitable work, literature, and chess, and he had reportedly planned to obtain a helicopter pilot's license. His early career was marked by controversy: before OnlyFans, he had created websites that claimed to direct users to pornographic content involving minors or bestiality, though Forbes magazine found no evidence that those sites actually hosted or redirected to such material, with Radvinsky instead earning money from each click. Forbes first named him a billionaire in 2021, and his net worth more than doubled in the years that followed, reaching $4.7 billion by the time of his death. OnlyFans was founded in 2016 by British entrepreneur Tim Stokely as a subscription-based content platform. The service gained significant mainstream attention during the COVID-19 pandemic beginning in 2020, when widespread lockdowns accelerated its growth. Radvinsky had also previously founded MyFreeCams, a webcam site, through his holding company MFCXY, Inc., prior to his acquisition of OnlyFans. No information on the cause of his specific cancer diagnosis or the timeline of his illness was made available by the company or his family, in keeping with the family's request for privacy.
