Mark Cuban dumps most Bitcoin and says it failed as a safe haven asset

Billionaire investor and entrepreneur Mark Cuban has revealed that he has sold the majority of his Bitcoin holdings. He says that the cryptocurrency has failed to perform as a reliable safe-haven asset during periods of global economic and geopolitical stress.

Cuban spent years saying Bitcoin was a better version of gold and even put 60% of his crypto portfolio into BTC. He called Bitcoin the best alternative to fiat currency and said its 21 million coins fixed supply is more trustworthy than gold.

However, speaking on the Front Office Sports podcast, Portfolio Players, Cuban said his view has shifted after observing how Bitcoin performed during recent market turmoil.

When all this shit hit the fan with the Iran war, Bitcoin was always the best alternative to fiat currency losing its value, and I always thought it was a better version of gold than gold. Well, gold just blew up… Bitcoin dropped. And every time the dollar dropped, Bitcoin should’ve gone up… and it just didn’t do that.

Why is Mark Cuban’s opinion on Bitcoin a big deal?

Mark Cuban is a billionaire investor with a net worth of roughly $10 billion, and has been one of the most publicly vocal supporters of Bitcoin and Ethereum for years.

When someone of his status makes a big move in or out of a market, it draws public attention. 

Before 2026, Cuban’s portfolio was made up of 60% Bitcoin, 30% Ethereum, and 10% everything else. He said BTC’s fixed supply and decentralized structure were the best hedge against governments printing too much money and devaluing the dollar.

However, he has since changed his opinion.

Why would anyone expect Bitcoin to act like a hedge?

Bitcoin has a fixed supply of 21 million coins, is a decentralized currency, which means no government can print more, and anyone worldwide can access it without using a bank.

That alone is why Cuban and many others believed BTC should behave like a hedge or gold during a crisis. When the dollar weakens, gold goes up, and so people thought Bitcoin would too.

However, Cuban says Bitcoin never went up during the Iran war or when the dollar fell. Instead, it dropped or stayed flat, while gold performed exactly as expected. 

According to Cuban, “The hedging effect never materialized.”

What really happened to Bitcoin and gold during the Iran conflict?

Cuban’s theory on gold makes sense because the asset set a record above $5,500 per ounce earlier this year. That is a 37% increase in the past 12 months, so gold performed as expected when the Iran war broke out.

His analysis of Bitcoin, however, does not match the reality on the ground.

That is because Bitcoin has risen more than 16% since the first signs of the US-Iran conflict emerged in late February 2026. During that same period, gold fell more than 15%.

This means Cuban may be comparing the wrong time windows.

In the past 12 months, Bitcoin has been down roughly 30%, while gold has been up 37%. But during the Iran conflict, specifically, Bitcoin outperformed gold.

So while Bitcoin did not behave as expected over the full 12-month window, it did better than gold during Cuban’s timeline of the Iran conflict. 

Does Cuban still believe in crypto?

Yes, Cuban may have exited Bitcoin, but he told the podcast that he is less disappointed in Ethereum. His reasoning is that Ethereum’s utility is more attractive than Bitcoin’s store-of-value appeal.

The billionaire is also a vocal supporter of crypto regulation. While others in the community see government involvement in crypto as a threat, he says regulation is a condition for mainstream adoption, not the enemy. 

He followed the debate over the CLARITY Act closely and said the rush to create crypto legislation through lobbying proves he was right years ago when he said regulation was inevitable and necessary.

The bigger debate Cuban has reopened

Cuban’s comments came at a time when the debate over whether Bitcoin is a digital or a speculative technology bet is still fresh.

The case for Bitcoin as digital gold rests on its fixed supply of 21 million coins, its decentralized nature, and its lack of counterparty risk. 

On the other hand, the case against Bitcoin as a hedge also makes sense because the cryptocurrency is only 16 years old, while gold has thousands of years of history as a safe haven.

BTC still trades more like a technology stock than a commodity during short-term stress events, falling when the S&P 500 falls sharply and rising when risk appetite returns. That pattern is not what a real safe-haven asset is supposed to do.

Mark Cuban landed on the skeptical side of that debate, but the wider conversation is still unsettled, and many investors remain in the other camp.
