Kevin O'Leary reveals the next big thing in crypto

Kevin O'Leary has declared that the next big crypto opportunity could be the blockchain that secures adoption from at least one S&P 500 company in each of the 11 sectors. In an X post on June 1, O'Leary said the next big thing in crypto is the chain that standardizes real-world utility for S&P 500 companies. From there, Mr. Wonderful concluded that the crypto asset whose blockchain integrates with these corporations may experience parabolic growth. "So I think the next big thing in crypto is which of these chains is going to get at least one company in all 11 sectors of the S&P. Because the minute that occurs, you wanna go long that token," O'Leary stated. The investor remains bullish on Bitcoin (BTC) and Ethereum (ETH) despite their significant drawdowns from their respective all-time highs (ATH). He also believes most crypto assets are "dead," particularly after the October 2025 capitulation event. As a result, he argued that any blockchain helping an S&P 500 company manage inventory, logistics, and contracts could recover fast.

Why aren't S&P 500 companies using crypto yet? The appetite for blockchain to streamline operations remains high, O'Leary said, but legal issues continue to be a major headwind. The U.S. blockchain industry still operates in a grey area without the Clarity Act — a proposed federal regulation aimed at legalizing crypto assets. O'Leary also pointed out that major Wall Street firms continue to watch Web3 from the sidelines due to a lack of security standards. Most top blockchains, meanwhile, have yet to ship tested, reliable privacy-centric smart contracts capable of onboarding S&P 500 companies at scale.

Blockchains that roll out enhanced security standards around the passage of the Clarity Act could find themselves near the top of the "next big thing" shortlist — assuming, of course, the shortlist isn't, like most of crypto, already dead.
