MrBeast invested $250,000 for a 55% stake in Ball 2, an AI-powered toy, during his debut on Shark Tank. Created by Andrew Brown and Kevin Langdon, the ball uses sensors and a companion app to track movement and generate interactive games. While MrBeast backed its viral potential, investors Kevin O'Leary and Lori Greiner questioned consumer demand. The product's success now depends on turning online attention into lasting sales.
