Mark Cuban: AI Could Bankrupt Us Into A Deep Debt Bubble!

Episode of The Diary Of A CEO with Steven Bartlett · October 26, 2026 · 1 h 31 min

Mark Cuban tells Steven Bartlett about his upbringing, sales, the Dallas Mavericks, why he thinks AI isn't smart, a possible AI debt bubble, family and Cost Plus Drugs.

Summary

Mark Cuban joined Steven Bartlett to talk about his blue-collar Pittsburgh upbringing, his early hustles selling baseball cards and garbage bags, and why he sees sales as the base of all business. He advised aspiring entrepreneurs to become great at one thing, avoid assuming they must raise money, prioritize profitability, and take any job and excel at it. He recounted founding MicroSolutions after being fired, teaching himself software, and later selling Broadcast.com to Yahoo.

On artificial intelligence, Cuban called it the biggest technology shift he had seen and a democratizer of information. He argued, though, that AI is not smart but a brute-force statistical predictor without ethics or real-time awareness, and said he was not an AI doomer. He said markets were in a bubble driven by meme-like trading, and warned that heavy borrowing by hyperscalers alongside rising US deficits and interest rates could produce a debt bubble. He described Elon Musk as a brilliant entrepreneur but fundamentally a salesman.

Cuban also described turning around the Dallas Mavericks through culture, player development, a team plane and early analytics hire Wayne Winston. He spoke about insecurity, the burdens of fame, his brother Brian's 2005 crisis and recovery (reading a letter from Brian), and how mortality and family led him to leave Shark Tank and sell the Mavericks. He closed by describing his mission to reform American healthcare through Cost Plus Drugs.

From the publisher

Are you looking to break free from the trap of a 9 to 5 job in the modern economy? Billionaire entrepreneur Mark Cuban, as he shares the raw truths about artificial intelligence, sales, and the reality of building an empire. Mark Cuban is a legendary American billionaire, investor, and former shark on ABC's Shark Tank, best known for transforming the Dallas Mavericks into NBA champions and building multi-million dollar tech enterprises like Broadcast.com and MicroSolutions. Today, he is fully dedicated to disrupting the American healthcare industry through his revolutionary online pharmacy, Cost Plus Drugs. In this episode, he explains: ■ The AI Illusion: How artificial intelligence is simply a brute force pattern matcher that lacks true human intelligence, meaning the real edge belongs to humans who leverage it to “out prepare” and “out learn” the competition. ■ The Power of Sales: Why very successful business is fundamentally built on sales, and mastering the ability to handle objections and rejection guarantees you a job for life. ■ The Danger of Quick Money: How modern social media algorithms feed youth an illusion of instant wealth, holding back a generation that refuses to put in the grueling preparation required to master a skill. ■ The Chemistry of Leadership: How turning around a failing sports franchise or a business requires ruthless commitment to team culture, hiring slowly, firing fast, and replacing ego with collective alignment. ■ The True Definition of Success: Why true wealth is ultimately about controlling your own time and destiny rather than buying luxury items, and prioritizing family above all else remains the ultimate life achievement.
