JPMorgan Chase & Co (JPM) CEO Jamie Dimon called Coinbase Global Inc (COIN) CEO Brian Armstrong “full of sh*t” on Friday, escalating a public dispute over US crypto legislation and prompting responses from executives and investors across the digital-asset industry.
Speaking in a Fox Business interview, Dimon criticized the CLARITY Act, which seeks to create a regulatory framework for digital assets in the US, arguing that it would allow stablecoin issuers to effectively pay interest on deposits without being subject to the same regulatory requirements as banks.
He said lenders, including the American Bankers Association (ABA), community banks, and credit unions, would oppose the legislation if it moves forward in its current form. Dimon explained that the CLARITY Act has “almost no legal protections,” and that “the banks will not accept it that way.”
JPMorgan’s price was down by 0.10% during after-hours trading. On Stocktwits, the retail sentiment around JPM moved to ‘neutral’ from the ‘bearish’ zone, while chatter around it stayed in the ‘normal’ levels over the past day.
Dimon also aimed at Coinbase, saying banks would not “bow down” to Armstrong or the exchange. He accused the Coinbase chief executive of spending heavily on advocacy around the legislation before calling him “full of sh*t.”
This was not their first confrontation. At the World Economic Forum in Davos, Switzerland, in January, Dimon allegedly approached Armstrong in person during a meeting with former UK PM Tony Blair and delivered the same verdict to him.
Coinbase’s price was down by 0.23% during after-hours trading. On Stocktwits, the retail sentiment around COIN remained in the ‘bearish’ zone, while chatter around it stayed in the ‘low’ levels over the past day.
Armstrong responded on X with a picture showing a “heated rivalry” between JPMorgan and Coinbase.

Despite Dimon’s attack on crypto legislation, JPMorgan has been quietly building stablecoin infrastructure, filing this month to launch a tokenized Treasury fund on Ethereum (ETH) designed specifically for stablecoin issuers. Dimon called blockchain a “legitimate technology” in the interview.
Dimon’s comments quickly drew pushback from crypto policy figures. Patrick Witt, Executive Director of the President's Council of Advisors for Digital Assets at the White House, challenged Dimon’s claims, saying the bill includes anti-money laundering (AML) provisions and restrictions on stablecoin yield payments.

Solana (SOL) co-founder Anatoly Yakovenko also joined the debate, questioning banks’ advantages from Treasury bill-related revenue.

Nate Geraci, President of NovaDius Wealth Management, meanwhile, compared banks’ opposition to crypto with “Netflix vs. Blockbuster,” saying lenders risk falling behind technological change.

The collision comes as banks, crypto companies, and lawmakers continue debating the CLARITY Act, which cleared the Senate Banking Committee in a bipartisan 15-9 vote earlier this month.
