We just covered the Mark Cuban Stock Portfolio: 8 Best Stocks to Buy and Amazon.com, Inc. (NASDAQ:AMZN) ranks 1st on this list.

For Mark Cuban, Amazon.com, Inc. (NASDAQ:AMZN) stock is a long-term, high-conviction buy and hold investment. This strategy has yielded massive returns for Cuban, by his own admission. During an appearance on the The David Rubenstein Show a few years ago, Cuban acknowledged that he held stock in the technology giant, even admitting that he had bought shares when it was trading at “$500 and $700 per share”, later increasing his holdings as the price jumped further. During an appearance on news platform CNBC, Cuban called Amazon “the smartest company in the universe” due to the ability to disrupt multiple industries, from retail to cloud computing and healthcare.

However, in recent years, Cuban has been publicly critical of some of the moves that Amazon.com, Inc. (NASDAQ:AMZN) has made. For example, in a recent post on social media, he has cautioned entrepreneurs against over-reliance on the platform, labeling high seller fees as “insane and unsustainable.” He views heavy dependency on Amazon as a structural risk for small businesses, noting that the cost structure of the platform can quickly erode margins. This creates a striking duality in his perspective: while he remains a major shareholder who profits from growth, he simultaneously warns that the very practices driving that growth can make the platform a dangerous partner for the startups he often mentors.

While we acknowledge the potential of AMZN as an investment, we believe certain AI stocks offer greater upside potential and carry less downside risk.
