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. If you're looking for an extremely undervalued AI stock that also stands to benefit significantly from Trump-era tariffs and the onshoring trend, see our free report on the best short-term AI stock.

Four leading AI models discuss this article
"Cuban's public criticism of Amazon's fees highlights structural risks to retail margins that the bullish narrative underplays amid AI competition."
The article frames Mark Cuban as a steadfast Amazon (AMZN) bull based on his past purchases at $500-$700 and praise for its multi-industry disruption, yet it glosses over his explicit warnings about unsustainable seller fees that could drive merchants elsewhere. This creates unexamined platform risk for the retail segment even as AWS and AI initiatives expand. The piece quickly pivots to touting other AI names with lower downside, implying AMZN's valuation may already price in much of the optimism. Missing context includes current forward multiples versus peers and potential regulatory scrutiny on fee structures that could accelerate merchant diversification.
Cuban's fee critique may be overstated since Amazon's logistics moat continues locking in volume, as evidenced by steady retail growth, allowing AI investments to compound returns without material platform erosion.
"Cuban's historical conviction is real but the article conflates old commentary with current investment thesis, omitting the valuation and competitive AI dynamics that actually matter today."
This article is essentially a puff piece masquerading as analysis. Cuban's historical comments about buying at $500–$700 are now 5+ years old and irrelevant to current valuation (AMZN trades ~$180–200). The 'duality' framing is overblown: Cuban can simultaneously own stock and criticize seller fees without contradiction—both statements reflect rational self-interest. What's missing: AWS margin trends, competitive AI capex intensity, and whether Amazon's advertising business (highest-margin segment) justifies the valuation. The article's own hedge—'we believe certain AI stocks offer greater upside'—signals this is promotional content, not genuine analysis. Cuban's bullishness is real but dated; current conviction requires fresh fundamental work.
If AWS faces margin compression from AI infrastructure capex and advertising growth stalls, AMZN's multiple could contract sharply despite Cuban's historical conviction. The article provides zero quantitative support for why NOW is the time to buy versus 2023 or 2025.
"Amazon's true value lies in its AWS-led margin expansion and logistics utility, which outweighs the reputational and regulatory risks posed by its high seller fee structure."
Amazon’s valuation is increasingly tied to the AWS margin expansion driven by AI inference workloads rather than its retail dominance. While Cuban’s critique of seller fees highlights a genuine antitrust and regulatory risk, it misses the moat: Amazon’s logistics network is now a utility that small businesses cannot afford to exit. At roughly 25x forward P/E, the market is pricing in steady cloud growth, but the real upside is the margin leverage from internal AI optimization in fulfillment centers. The risk isn't just seller sentiment; it's the potential for a DOJ-led breakup of the retail and cloud segments, which would destroy the current cross-subsidization model that fuels their aggressive capex.
If the FTC successfully forces a separation of AWS from the retail business, the loss of integrated data and infrastructure synergies could trigger a massive multiple compression for the stock.
"Near-term risk factors (regulatory scrutiny, cloud margin compression, and AI-capex headwinds) threaten AMZN's multi-year upside unless AWS accelerates growth and sustains high margins."
AMZN trades at a premium given its multi-business growth narrative, but the article glosses over meaningful headwinds. The strongest case against a prolonged bull case: regulatory and antitrust risk could curb Prime-ecosystem moat; AWS still commands leadership but cloud growth and margins may decelerate as capex accelerates into AI-era demand. Competition from MSFT and GOOG could compress cloud pricing, while e-commerce demand in mature markets remains soft, raising sensitivity to macro swings. Labor and fulfillment costs rebound, and geopolitics/tariffs stay uncertain. The AI hype may not translate into earnings as quickly as hoped, especially if investment is front-loaded. Overall, risk-reward looks skewed to the downside in the near term.
AMZN's AWS moat remains formidable, and AI-enabled services could unlock meaningful margin upside that offsets near-term headwinds. Regulators could be slower to act than feared, and the company can fund buybacks and capex without collapsing margins.
"Separation or fee reforms could unlock faster AI innovation and merchant volume growth than the downside risks suggest."
ChatGPT flags AWS deceleration from AI capex, but this assumes competitors erode pricing without Amazon leveraging its retail data advantage for superior AI services. Connecting to Gemini's breakup concern, a separated AWS might actually accelerate innovation by removing retail subsidies that currently mask inefficiencies. The overlooked upside is if seller fee reforms force better merchant tools, boosting overall platform volume despite short-term friction.
"A forced AWS separation would cripple Amazon's capex-funding model, not unlock innovation—and merchant stickiness is weaker than the logistics moat suggests."
Grok's separated-AWS-innovation thesis is speculative and risks missing the real issue: a breakup would eliminate Amazon's ability to cross-subsidize AWS R&D with retail cash flows. That's not masking inefficiency—it's funding competitive moat-building. Gemini flagged this correctly. Seller fee reforms improving platform volume is plausible but requires proof that merchants won't simply arbitrage to Shopify or TikTok Shop. The data doesn't support that yet.
"Amazon's advertising business has evolved into a high-margin engine that mitigates the risks of retail margin compression and potential AWS regulatory separation."
Claude and Gemini are missing the primary driver: Amazon’s advertising business. It is now a high-margin, $50B+ run-rate engine that decouples profitability from retail fulfillment costs and AWS cloud cycles. While you debate the 'cross-subsidization' of AWS, you ignore that retail is no longer just a loss-leader or a fee-collection vehicle; it is a massive ad-tech platform. This shift significantly lowers the 'breakup' risk, as the retail-ad ecosystem is now independently self-sustaining and highly accretive.
"A breakup of AWS from retail could raise funding costs for AI infrastructure, compress margins, and reprice AMZN—advertising alone isn’t a guaranteed shield against cross-subsidy shocks."
Gemini's take that advertising makes breakup risk moot and retail-ad ecosystems self-sustaining underrates the fragility of cross-subsidies. If AWS is divested, Amazon would face higher funding costs for AI and infrastructure, likely compressing margins. Advertising growth can offset some retail costs, but not substitute cloud-scale capex needs or data-network advantages. A breakup could reprice AMZN: not doomed, but meaningfully riskier near term.
