OnlyFans Owner Leonid Radvinsky Dies at 43 After Cancer Battle

Leonid Radvinsky, the Ukrainian-born billionaire owner of the adult content site OnlyFans, has died at the age of 43 after a long battle with cancer, according to multiple media reports.

Radvinsky “passed away peacefully” following a prolonged illness, Bloomberg cited an emailed statement from the London-based company as saying on Monday. His illness had not been publicly disclosed.

According to Forbes, Radvinsky’s net worth stood at $4.7 billion as of Monday. OnlyFans reported $1.4 billion in revenue in 2024, with users spending a record $7.2 billion on the platform. Radvinsky paid himself $1.8 billion in dividends between 2021 and early 2025.

In his early years, Radvinsky ran websites advertising access to “hacked” passwords to porn sites, which generated revenue via referrals and clicks. In 2004 he was sued by Microsoft over alleged spam emails, although the case was ultimately dismissed.

In 2022, OnlyFans was accused of sabotaging social media accounts of adult entertainers working for rival platforms by placing their content in a terrorism database.

More recently, leaked internal documents from the American Israel Public Affairs Committee (AIPAC), a pro-Israel lobbying group, reported by independent investigative news outlet The Lever, Radvinsky and his wife were listed as having pledged $11 million to the organization in 2023 – a sum that would make him a major donor – although he denied making the donation.

Born into a Jewish family in the Ukrainian city of Odessa in 1982, Radvinsky emigrated to the United States as a child.

He bought a majority stake in OnlyFans’ parent company in 2018. The platform gained prominence by hosting explicit content largely restricted on mainstream social media. Its popularity surged during the pandemic, as many adult performers and sex workers moved online in search of alternative income streams.

Debates around the platform have played out in Ukraine. Last year, a senior lawmaker said Kiev was missing out on around one billion hryvnas ($24 million) annually in tax revenue due to the country’s ban on pornography, despite thousands of Ukrainian OnlyFans creators generating an estimated $120 million in 2023.
