When Kevin O’Leary—known worldwide for his Shark Tank appearances—announced that he had sold every one of his 27 altcoin holdings, the move was more than a portfolio trim; it was a signal of where he believes the next wave of growth will occur.

In a recent interview on the Money Rehab podcast, the Canadian investor revealed that he now holds only Bitcoin (BTC), Ethereum (ETH), and Circle’s USD‑coin (USDC). He said power‑infrastructure companies have become his highest‑conviction investment.

O’Leary recalled the broader crypto market’s collapse, which he dubbed a “poo‑poo” era. An unnamed institutional analyst had shown that BTC and ETH accounted for 97 % of the market’s volatility, prompting him to pare his crypto exposure from 24 % of his portfolio down to 14 %. "I actually think the play that will outperform will be just pure power," he explained.

He outlined a strategy focused on turbine manufacturers, transmission firms, and companies that aggregate power contracts from nuclear and hydro sources. He singled out Bitzero Holdings (AIBZ) as the best crypto‑adjacent investment he has seen: a company that owns and operates data‑center‑grade power infrastructure for both AI and Bitcoin workloads. "They just have power, land, fiber, and a permit. They don't care. It's a hyperscaler. It's AI or Bitcoin," O’Leary said.

AIBZ’s stock slipped more than 3 % on Friday, and retail sentiment on Stocktwits remained bearish. The firm’s model—providing reliable, large‑scale power to meet the growing demands of AI training and cryptocurrency mining—positions it to benefit from the sector’s expanding energy needs.

O’Leary’s comments echo earlier statements he made this year when he said the correction had cleared out the “poo‑poo” coins, leaving BTC and ETH as the only institutional focus. The difference now is that he no longer regards even those two assets as his top bet; instead, he sees power infrastructure as the most valuable opportunity.

The shift reflects broader market dynamics. Bitcoin and Ethereum continue to dominate the crypto market, accounting for the majority of trading volume and market capitalization. However, the energy consumption of Bitcoin mining and the data‑center requirements of AI have intensified the need for reliable, large‑scale power supply. Companies that can provide that infrastructure—whether through renewable sources or efficient transmission—are likely to see increased demand.

O’Leary’s portfolio change also highlights a trend among some institutional investors who are moving away from speculative altcoins and focusing on assets with clearer regulatory footing and utility. BTC, ETH, and USDC remain among the few cryptocurrencies that have attracted institutional interest due to their liquidity, market depth, and, in the case of USDC, regulatory compliance.

The investor’s remarks come amid a broader conversation about the sustainability of crypto mining and the role of renewable energy. Several mining firms have announced plans to source electricity from hydroelectric and solar projects, while data‑center operators are exploring carbon‑neutral power options.

In the short term, O’Leary’s decision may influence other investors who track his moves, potentially leading to a modest shift in capital toward power‑infrastructure stocks. In the longer term, the alignment of AI and cryptocurrency demand with energy supply could accelerate investment in the sector.

As of the latest market data, Bitcoin’s price has been trading flat over the past 24 hours, and retail sentiment on Stocktwits remains bearish. Ethereum and USDC have not seen significant price swings, and O’Leary’s focus on power infrastructure suggests he is looking beyond the crypto market for growth.

The investor’s move underscores the evolving relationship between cryptocurrency and energy markets. While BTC and ETH remain the most widely held digital assets, the infrastructure that powers their operations is gaining attention as a separate investment class. O’Leary’s pivot may signal a broader trend in which energy infrastructure becomes a key component of the crypto ecosystem’s financial architecture.
