Coinbase CEO Brian Armstrong posted a hockey-themed competition meme to X on Friday, hours after JPMorgan Chase CEO Jamie Dimon appeared on Fox Business. morning with maria Called Armstrong “full of shit” for his lobbying efforts on the Digital Asset Market Clarity Act.
The exchange escalated a months-long public feud between the heads of Wall Street’s biggest banks and the CEOs of cryptocurrency’s most prominent exchanges, now focused on a single sticking issue: whether cryptocurrency platforms should be allowed to pay yields on stablecoin balances without being subject to bank-style regulation.
What Dimon Said and What It Means
“It effectively allows cryptocurrency companies to pay interest on deposits, stablecoins or something like that without the protection they deserve. Banks are not going to take it that way,” Dimon said during a May 29 appearance on Fox Business. He warned that if passed as written, the system would “eventually implode” and accused Armstrong of spending hundreds of millions of dollars in Washington to push the bill. “No one will bow to this man,” Dimon said.
Galaxy Digital CEO Mike Novogratz joined the response to Novogratz argued that lawmakers, not financial institutions, should decide the framework for digital assets.
Friction between Dimon and Armstrong is nothing new. At the World Economic Forum in Davos in January 2026, Dimon reportedly told Armstrong directly, “You are full of shit,” during a closed-door meeting that also included former British Prime Minister Tony Blair. Bank of America CEO Brian Moynihan also reportedly told Armstrong at Davos: “If you want to be a bank, be a bank.” Coinbase withdrew its support for the Clarity Act in January after a Senate draft included a provision that would effectively ban yields on stablecoin balances, prompting Senate Banking Committee Chairman Tim Scott to cancel a planned vote.
In May, a compromise emerged that would allow activity-based rewards and ban passive revenue. As crypto.news reported, Armstrong supported the updated bill ahead of its May 14 markup by the Senate Banking Committee, which advanced the bill 15-9. Despite these developments, Dimon’s comments Friday signaled that JPMorgan and allied banks intend to withdraw the primary vote.
For Coinbase, the stake is direct. Coinbase reported $1.35 billion in stablecoin revenue in 2025, making yield regulation as much a revenue variable as a policy preference. Alex Thorn, head of Galaxy Research, currently gives the Clarity Act a 70% chance of passing before the August recess, while Polymarket traders give it a 61% chance. Dimon’s public opposition, which bolsters the influence of America’s largest bank, is adding to institutional friction at the very moment when the bill’s deadline is at its shortest.
