YouTube star Jimmy Donaldson, known as MrBeast, is seeking to raise several hundred million dollars, valuing his company at approximately $5 billion. The funds will support a holding company for his ventures, including Feastables and Lunchly, and expand his media operations, which generated over $400 million in revenue last year. Additionally, he has launched “Beast Games” on Amazon Prime Video, the platform's most-watched unscripted series.
