Brian Armstrong fired back at Jamie Dimon on Friday with a meme, after the JPMorgan CEO attacked him on live TV.
Summary
- Jamie Dimon appeared on Fox Business on May 29, calling Armstrong “full of sh!t” and vowing that banks will fight the Clarity Act’s stablecoin provisions.
- Armstrong responded on X with a hockey-themed meme depicting himself and Dimon facing off, while Galaxy CEO Mike Novogratz publicly backed Armstrong.
- Dimon’s core objection is that the Clarity Act lets crypto firms effectively pay interest on stablecoin deposits without bank-level oversight.
Coinbase CEO Brian Armstrong posted a hockey-themed rivalry meme on X on Friday, hours after JPMorgan Chase CEO Jamie Dimon appeared on Fox Business’s Mornings with Maria and called Armstrong “full of sh!t” over his lobbying push for the Digital Asset Market Clarity Act.
The exchange escalated a months-long public feud between Wall Street’s largest bank chief and crypto’s most prominent exchange CEO, now centred on a single sticking point: whether crypto platforms should be allowed to pay yield on stablecoin balances without submitting to bank-style regulation.
What Dimon said and what it means
Appearing on Fox Business on May 29, Dimon said: “It allows cryptocurrency firms to effectively pay interest on deposits, stablecoins or something like that, without the protection that they should have. The banks will not accept it that way.” He warned the system would “eventually blow up” if passed as written, and accused Armstrong of spending hundreds of millions of dollars in Washington to push the bill. “No one is going to bow down to this guy,” Dimon said.
Galaxy Digital CEO Mike Novogratz joined the response on X, writing: “Since when do banks get to decide on legislation?” Novogratz argued that lawmakers, not financial institutions, should determine the framework for digital assets.
The friction between Dimon and Armstrong is not new. At the World Economic Forum in Davos in January 2026, Dimon reportedly told Armstrong directly “you are full of sh!t” in a private meeting that also included former UK Prime Minister Tony Blair. Bank of America CEO Brian Moynihan also reportedly told Armstrong at Davos: “If you want to be a bank, just be a bank.” Coinbase pulled its support for the Clarity Act in January after a Senate draft included provisions that would have effectively banned yield on stablecoin balances, a withdrawal that forced Senate Banking Committee Chair Tim Scott to cancel a scheduled vote.
By May, a compromise had emerged allowing activity-based rewards while banning passive yield. As crypto.news reported, Armstrong backed the updated bill ahead of the Senate Banking Committee’s May 14 markup, which advanced the legislation 15 to 9. Despite that progress, Dimon’s Friday comments signalled that JPMorgan and allied banks intend to push back on the floor vote.
For Coinbase, the stakes are direct. Coinbase reported $1.35 billion in stablecoin revenue in 2025, making the yield provisions a revenue variable as much as a policy preference. Galaxy Research head Alex Thorn currently gives the Clarity Act 70% odds of passing before August recess, while Polymarket traders price it at 61%. Dimon’s public opposition, backed by the weight of America’s largest bank, adds institutional friction at precisely the moment the bill’s floor timeline is most compressed.
