Leonid Radvinsky, the billionaire owner of OnlyFans, has died from cancer at the age of 43. His passing, which occurred on March 24, 2026, was confirmed by a spokesperson for the company.

Radvinsky’s death was not made public immediately after he passed; he had died several days earlier. Insiders were aware of his health issues for some time, but the news of his death has nonetheless come as a shock to many.

Radvinsky acquired Fenix International Limited, the parent company of OnlyFans, in 2018 and transformed the pornography industry with the platform’s subscription-based model. OnlyFans allows creators to charge directly for their content, retaining 20% of their earnings.

Under Radvinsky’s leadership, OnlyFans reportedly generated $7.4 billion in revenue, particularly seeing a surge during the pandemic when the platform added approximately 300,000 users daily. His innovative approach reshaped the economics of the adult content industry, enabling creators to reach audiences directly.

Born in Ukraine and raised in Chicago, Radvinsky studied economics at Northwestern University. He was also known for his philanthropic efforts, including a $23 million grant for cancer research supported by him and his wife, Yekaterina ‘Katie’ Chudnovsky.

Before his death, Radvinsky lived in a $19 million oceanfront condominium in Miami. His only known public photo is from a gala event in 2024, highlighting his preference for a private life despite the public nature of his business.

Andy Bachman, a close associate, remarked, “Insiders knew [Radvinsky] had been dealing with health issues for some time, and while his passing is tragic, he left behind a company that was fully prepared and resilient.”

Another industry figure, Sophie Rain, expressed gratitude for Radvinsky’s contributions, stating, “I will never forget that. That platform gave me everything. And that doesn’t happen without someone building it in the first place.”

Radvinsky’s legacy will likely continue to influence the adult content industry for years to come, as he has left a significant mark on how creators monetize their work.
