I Asked ChatGPT About Mark Cuban's Best Advice -- and Whether It Holds Up Today

Billionaire investor and entrepreneur Mark Cuban has built a reputation for blunt, practical money advice. The longtime "Shark Tank" investor and Dallas Mavericks owner has shared countless financial tips for everyday people over the past two decades.
But does it still hold up today?
I decided to ask ChatGPT to review some of Cuban's most popular advice over the years and tell me whether the advice still holds up in 2026. Here's what it said.

Avoid Credit Card Debt at All Costs
Cuban has said many times over the years to avoid credit card debt if at all possible -- as reported by CNBC, for instance.
And if you do have credit card debt, Cuban favors paying it off first, and it provides the highest guaranteed rate of return compared to other investments. For example, if your credit card charges 20% interest, paying down that debt is essentially the same as earning a 20% return on your money.
ChatGPT confirmed that this advice still holds up today. Credit card interest rates have risen significantly in recent years, with average APRs often exceeding 25%. This confirms that prioritizing debt repayment remains one of the smartest financial moves available.
Build an Emergency Fund
Cuban has also repeatedly emphasized the importance of having cash set aside to help with unexpected expenses, as MoneyLion previously reported.
According to ChatGPT, this advice remains relevant today, especially in light of economic uncertainty, layoffs and the rising cost of living. Most financial experts recommend having at least three to six months of essential expenses set aside in a high-yield savings account.
Without an emergency fund, you are at risk of reaching for the credit card when life's unexpected emergencies arise.
Invest In Low-Cost Index Funds
Cuban is a fan of passive investing, similar to billionaires like Warren Buffett, and suggests that low-cost index funds are a better investing strategy for most vs. picking individual stocks.
ChatGPT noted that this advice still aligns with a large body of research on passive investing vs. active investing. In addition to outperformance, index funds also offer broad diversification and lower fees compared to actively managed investments.
Does Cuban's Advice Still Work?
ChatGPT agreed that Cuban's core money advice is still relevant today. It's still smart to avoid high-interest debt, keep cash for emergencies, and invest in low-cost index funds, and those principles don't seem to be going away any time soon.
But as with any financial advice, you can't just copy/paste someone else's strategy but need to adapt it to your own circumstances. This is where finding a quality fee-only financial advisor can help you put the pieces of the puzzle together.
