OnlyFans, the adult-content platform, has agreed to sell a 16% stake to Architect Capital for $535 million, valuing the U.K.-based company at $3.15 billion. The deal announced Friday follows the recent death of OnlyFans owner Leo Radvinsky from cancer, ending months of investment talks.

The transaction represents a significant financial milestone for OnlyFans, which has grown into a major digital content platform. Architect Capital, typically focused on financial infrastructure investments, sees value in OnlyFans' business model despite previous challenges regarding payment processing and content moderation.

The valuation underscores OnlyFans' position as a dominant player in the creator economy, particularly within adult content. The investment provides OnlyFans with capital for expansion while potentially bringing more traditional financial infrastructure to its platform.
