OnlyFans announced Friday that it reached a deal to sell a roughly 16% stake to Architect Capital that values the porn streaming site at $3.15 billion, after the Silicon Valley investment firm struggled to clinch backers.

Fenix International Limited, which owns OnlyFans, said the deal includes a $535 million investment that will help the revolutionary nudie site offer new financial services for its creators, “who are often underserved by traditional financial institutions and products.”

Architect Capital is set to receive backing from a special-purpose vehicle with money raised from a group of investors. James Packer, a media and casino mogul who is one of the richest people in Australia, and Sam Lessin, a venture capitalist and early investor in Venmo, are among those backing the deal, according to the Financial Times.

OnlyFans declined to comment. Architect did not immediately respond to The Post’s request for comment.

Architect Capital – a San Francisco-based investment firm known for controversial bets like the Juul vaping brand – had been angling to buy a much larger 60% stake before OnlyFans owner Leonid Radvinsky’s shocking death in March, as The Post exclusively reported.

Radvinsky died at age 43 after a secret battle with cancer. The minority stake sale to Architect will leave control of the business to a family trust led by Katie Chudnovsky, his widow.

In the wake of the reclusive owner’s death, Architect struggled to find backers for its bid to acquire OnlyFans – even as the company turned around an eye-popping $666 million in operating profit on $1.4 billion in revenue in fiscal year 2025.

Despite the platform’s staggering earnings, investors were skeptical that OnlyFans would ever be able to go public due to investing guidelines that largely restrict the porn industry.

X-rated sites typically face higher transaction fees – often 5% to 10% versus 2% to 3% – and Visa last year started enforcing stricter chargeback and fraud standards on the company.

OnlyFans was looking to address the long-running banking woes through a partnership with a financial services firm, The Post reported earlier this year.

“Our mission has always been to empower creators and fans by providing a unique set of tools to create, monetise, and engage with content online,” OnlyFans CEO Keily Blair said in a statement Friday. 

“This strategic investment reflects our success in delivering this mission, and will enable us to build additional services and features to support our creator community and enhance OnlyFans’ position in the creator economy.”

Radvinsky acquired Fenix International in 2018, about two years after OnlyFans was created, and remained a director and the company’s majority shareholder for the next eight years.

The Ukranian-American entrepreneur revolutionized the porn industry, allowing adult content creators to reach their audience directly with subscriptions and keep 80% of their revenue – with some of the site’s top workers raking in tens of millions of dollars annually.

Popular creator Sophie Rain thanked Radvinsky for changing her life in an emotional tribute after his death. She said between 2023 and 2025, she earned a jaw-dropping $95 million through OnlyFans.

The NSFW site says it has facilitated over $25 billion in payments to creators over the past 10 years. It boasts over 4 million creators and 377 million fan accounts worldwide.
