Kevin O’Leary said Bitcoin and Ethereum remain the only crypto assets institutions really need, warning that most smaller tokens have failed to justify their place in serious portfolios.
The Shark Tank investor said large institutions are preparing for index-style crypto exposure, but that process is concentrating attention around BTC and ETH rather than the wider altcoin market.
“Meanwhile, the tragedy since last October on all of the old coins, and I call them ‘poopy coins,’ they got slaughtered because the large institutions are preparing for indexing,” O’Leary said.
He added that he believes institutional investors can capture most of the crypto market’s relevant exposure through just Bitcoin and Ethereum.
“I figured out that 97% of the entire value of the entire market is simply BTC and ETH,” O’Leary said. “That’s all you need to own. You don’t need to own anything else.”
The remarks expand on O’Leary’s recent public position that most altcoins lack staying power as institutional capital reshapes the market. In an April 22 Fox Business appearance, O’Leary said investors only need Bitcoin and Ethereum to capture most of the volatility from smaller tokens, while thousands of altcoins failed to recover after last October’s downturn.
O’Leary says altcoins lost the institutional race
O’Leary framed the altcoin selloff not as a short-term market correction, but as a structural shift driven by institutional due diligence.
His argument is that large allocators are not preparing to buy hundreds of tokens. Instead, they are looking for indexable exposure, liquidity, regulatory clarity and assets that can survive institutional scrutiny.
That puts Bitcoin and Ethereum in a different category from smaller tokens, according to O’Leary. Bitcoin already receives constant mainstream market visibility, while Ethereum remains the second crypto asset most commonly recognized by institutional investors.
“Think about the ticker you see on any business cable channel or anything online,” he said. “You see BTC quoted every morning, and they get that for free worldwide.”
He added that Ethereum appears far less often, while most other tokens get no mainstream visibility at all. For smaller chains, he said, gaining that level of recognition would require massive marketing budgets that many foundations no longer have after deep treasury losses.
The real blockchain opportunity is still enterprise adoption
O’Leary said the next major crypto opportunity will not come from another speculative token cycle, but from a blockchain network that can prove real adoption by major public companies.
He said the greenfield opportunity is still the same one the industry has discussed for years: bringing blockchain infrastructure into the S&P 500.
“The one greenfield, the one monster opportunity, and nobody’s been able to figure it out yet, is we’ve been talking about blockchain and the S&P 500 for almost 15 years,” O’Leary said.
He argued that the winning chain will be the one that can show major companies standardizing on its technology for use cases such as contract management, logistics and inventory management.
“You see this S&P 500 company that just standardized on my chain? Oh, here’s another one. Here’s another one. Here’s another one,” he said. “We’re becoming the standard for the S&P 500.”
According to O’Leary, that kind of adoption would create a real moat because it would be tied to productivity and margin improvement, not just token speculation.
AI is putting pressure on blockchain software narratives
O’Leary also warned that blockchain projects are competing in a tougher software environment because artificial intelligence has already pressured the enterprise software market.
He said AI has “slaughtered” parts of enterprise software over the past 12 months because it may replace some traditional software functions. That makes it harder for blockchain platforms to claim value unless they can show real enterprise adoption.
“If the thesis is that blockchain is just software, that’s putting additional pressure,” O’Leary said.
In that environment, he argued, only platforms that can demonstrate measurable corporate adoption will stand out. Without that proof, smaller tokens risk remaining speculative assets with weak institutional demand.
Tokenization still needs regulatory infrastructure
O’Leary still said he believes in tokenization, but he argued that institutional adoption will not happen until digital assets become fully compliant under a clear U.S. regulatory framework.
“I believe in tokenization, and I have for the last 10 years,” he said. “Here’s the problem… tokenization will never be adopted by institutional indexes ever. Neither will Bitcoin, which is still a fringe asset to the big guys.”
Consensus Miami 2026 has positioned institutional integration as one of its core themes, with allocators, asset managers, banks and service providers focused on frameworks that can bring crypto into traditional finance.
O’Leary said stablecoins show what happens when regulation gives institutions enough comfort to use blockchain rails. He pointed to USDC, while disclosing that he is a Circle shareholder, and said stablecoins are already improving cross-border transactions by moving value in minutes at lower cost than traditional settlement systems.
Power and AI data centers become O’Leary’s picks-and-shovels bet
Beyond tokens, O’Leary said he is more interested in the infrastructure needed to power crypto, AI and data centers.
“My thesis about investing in digital technology in crypto and the adoption of all this was how can I invest in the picks and shovels?” he said.
He said every major blockchain and AI platform needs data centers, power, permits, dark fiber and reliable jurisdictions. Instead of betting on which token or technology stack wins, O’Leary said he prefers companies with low-cost power contracts and access to sustainable energy sources such as hydro, nuclear and natural gas.
The comments come as O’Leary has been linked to major U.S. data-center expansion plans. Recent reports said his Utah project could span 40,000 acres and require up to 9 gigawatts of power.
For crypto markets, however, his core message was clear: institutional adoption is no longer a broad altcoin story. In O’Leary’s view, the market is narrowing around Bitcoin, Ethereum and the infrastructure needed to support the next phase of digital finance.
