After 15 unforgettable seasons, Mark Cuban has officially said goodbye to Shark Tank. In his final episode, now streaming on Hulu, the billionaire entrepreneur raised a heartfelt toast to his fellow sharks and loyal fans.

“I’ve learned so much from all of you,” he said, addressing Barbara Corcoran, Lori Greiner, Robert Herjavec, Daymond John, and Kevin O’Leary. “I love you guys like family.”

Cuban, who cited personal and family reasons for stepping away, was met with touching words from each shark. Corcoran compared his departure to “a big brother leaving the house,” while John praised Cuban for his world-changing impact.

Even Kevin O’Leary, his frequent on-air rival, acknowledged Cuban’s influence, calling them ambassadors of the American Dream—before sneaking in a trademark jab: “Sometimes you learned a lot from me,” prompting laughter from the room.

Cuban, known for his candid style and passion for entrepreneurship, reflected on his journey: “I’ve been broke, I’ve slept on the floor—I know what it’s like.”

Though he’s stepping away from the tank, his legacy will swim on.
