JPMorgan Chase

Jamie Dimon, the CEO of JPMorgan Chase, is famous for his outspoken contempt for Bitcoin. Look a little closer, though, and youíll notice that the U.S.'s biggest bank is not only a major player in blockchain but a significant innovator. For more than a decade, JPMorgan has been experimenting with in-house cryptocurrencies and ways to integrate blockchain into the banking system. Recent initiatives include issuing debt instruments on Solana and launching deposit tokens on Base.

In April 2026, JPMorgan named former Goldman Sachs banker Oliver Harris to lead its sizable crypto operation, which it has rebranded from Onyx to Kinexys. Still, Dimon appears determined to embrace crypto on his own terms, sparring with the likes of Coinbase over crypto legislation, and reportedly joining a coalition of other big banks to introduce a system of tokenized deposits. Founded as an investment bank whose roots date to 1871, JPMorgan Chase took on its current name upon merging with banking giant Chase Manhattan Corporation in 2000.
