📈 Mark Cuban—billionaire entrepreneur, Shark Tank investor, and former Dallas Mavericks owner—has been one of the most visible public figures in crypto. But his portfolio isn't static. This guide breaks down what Cuban has owned, why his views have shifted, how to evaluate crypto investments like his, and what to avoid.
For years, Mark Cuban was transparent about his crypto allocation. In multiple interviews—including a well-known 2021 appearance on The Delphi Podcast—he stated that his crypto portfolio consisted of roughly:
Cuban called Bitcoin "a better version of gold" and said its fixed supply of 21 million coins made it more trustworthy than gold.[reference:2] He also stressed that he never sold his Bitcoin—until 2026.[reference:3]
Cuban’s relationship with crypto has been anything but static. He has cycled through skepticism, enthusiasm, and—most recently—disappointment.
In 2019, Cuban famously said he would "rather have bananas" than Bitcoin.[reference:4] But by 2021, he had done a complete reversal. He revealed his 60/30/10 split and became one of the most vocal Bitcoin advocates among billionaires.[reference:5]
Cuban’s Dallas Mavericks became the first NBA team to accept Bitcoin for tickets and merchandise in 2019, later adding Dogecoin in 2021.[reference:6] He invested in more than 20 blockchain companies through Mark Cuban Companies.[reference:7][reference:8] He repeatedly endorsed Bitcoin over gold, saying he would buy it "all day, every day."[reference:9]
In May 2026, Cuban told the Front Office Sports Portfolio Players podcast that he had sold most of his Bitcoin.[reference:10][reference:11] His reasoning: Bitcoin failed to act as a safe-haven asset during the Iran conflict. While gold surged, Bitcoin dropped.[reference:12][reference:13]
He remains less disappointed in Ethereum, which he still holds.[reference:16][reference:17]
Unlike Bitcoin, Cuban has not sold his Ethereum. His reasoning centers on utility rather than store-of-value.
Cuban has called Ethereum "the closest thing to a real currency" and believes its technology has more long-term potential than Bitcoin’s "digital gold" narrative.[reference:21]
Beyond Bitcoin and Ethereum, Cuban has built a substantial presence in NFTs and blockchain startups.
Cuban owns more than 100 NFTs across Ethereum, Polygon, and Solana.[reference:22] At one point, his wallet held roughly 1,600 NFTs valued at over 1,900 ETH (around $6 million).[reference:23] He has sold some—including a Pudgy Penguin for over $30,000—but retains a large collection.[reference:24]
Cuban has invested in more than 20 blockchain companies, including:
Cuban’s approach offers a useful framework—even if you disagree with his conclusions. Here’s how to think about crypto investments the way he does.
Cuban bought Bitcoin because he believed in the "digital gold" thesis: fixed supply, decentralized, hedge against inflation.[reference:29] When the thesis failed in his view, he sold. Always know why you are buying.
Cuban separates Bitcoin (store of value) from Ethereum (utility). He values Ethereum for what it does, not just what it is. Ask yourself: does this asset have a use case beyond speculation?
Cuban’s 2026 sell-off was triggered by geopolitical conflict and Bitcoin’s price reaction.[reference:30] Pay attention to how assets behave during crises—not just during bull markets.
Cuban’s 60/30/10 split was intentional. He didn’t throw money at random tokens; he allocated based on conviction. His 10% "everything else" was for experimentation.[reference:31]
Cuban went from "bananas over Bitcoin" to "Bitcoin over gold" to "Bitcoin has lost the plot."[reference:32][reference:33][reference:34] That’s not inconsistency—it’s learning. Good investors update their views when evidence changes.
The table below summarizes Cuban’s known crypto allocations and sentiment at key points.
| Time Period | Bitcoin (BTC) | Ethereum (ETH) | Other / Meme Coins | Overall Sentiment |
|---|---|---|---|---|
| 2019 | Minimal / skeptical | Minimal | — | 😕 "Rather have bananas" |
| 2021–2024 | ~60% | ~30% | ~10% (incl. Dogecoin) | 🔥 Bullish on Bitcoin & Ethereum |
| Early 2025 | ~60% (still holding) | ~30% | ~10% | 👍 Recommends Bitcoin over gold |
| May 2026 | Sold most (~80%) | Still holds | Reduced / calls memecoins "garbage" | 😞 Disappointed in Bitcoin; favors Ethereum |

Before buying any cryptocurrency—whether it's Bitcoin, Ethereum, or a smaller token—use this checklist to make a more informed decision.
What you might do: Panic-sell your Bitcoin because a billionaire did.
What Cuban would likely advise: Don't blindly copy anyone. Cuban himself said he was disappointed, but he also acknowledged that Bitcoin rose during parts of the Iran conflict.[reference:40] He didn't sell all of it—he kept some exposure and maintained his Ethereum position.[reference:41]
A better approach: Use Cuban's move as a data point, not an instruction. Re-evaluate your own thesis. If you bought Bitcoin as a long-term store of value, ask yourself whether that thesis still holds for you.
