Brian Armstrong fired back at Jamie Dimon with a meme on Friday, after the JPMorgan CEO attacked him on live television.
Summary
- Jamie Dimon appeared on Fox Business on May 29, calling Armstrong “full of shit” and vowing that banks will fight against the stable provisions of the Clarity Act.
- Armstrong responded on X with a hockey-themed meme depicting himself and Dimon facing off, while Galaxy CEO Mike Novogratz publicly supported Armstrong.
- Dimon’s main objection is that the Clarity Act allows crypto companies to effectively pay interest on stablecoin deposits without bank 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. Mornings with Maria and called Armstrong “full of shit” because of his lobbying efforts for the Digital Asset Market Clarity Act.
The exchange escalated a months-long public feud between Wall Street’s top bank chief and crypto’s most high-profile exchange CEO, now centered on a single sticking point: whether crypto platforms should be allowed to pay a yield on stablecoin balances without subjecting themselves to bank-style regulation.
What Dimon Said and What It Means
Appearing on Fox Business on May 29, Dimon said: “It allows cryptocurrency companies to effectively pay interest on deposits, stablecoins or something like that, without the protection that they should have. Banks won’t accept it that way.” He warned that the system would “eventually explode” if it were passed as written, and accused Armstrong of spending hundreds of millions of dollars in Washington to get the bill passed. “No one is going to bow to this guy,” Dimon said.
Galaxy Digital CEO Mike Novogratz joined in the response on X, writing: “Since when do banks decide on legislation? Novogratz argued that lawmakers, not financial institutions, should determine the framework for digital assets.
The friction between Dimon and Armstrong is nothing new. At the World Economic Forum in Davos in January 2026, Dimon reportedly told Armstrong directly “you’re full of shit” during a private meeting also attended by former British Prime Minister Tony Blair. Bank of America CEO Brian Moynihan also reportedly told Armstrong in Davos, “If you want to be a bank, just be a bank.” Coinbase withdrew its support for the Clarity Act in January after a Senate bill included provisions that would have effectively banned stablecoin yield, a withdrawal that forced Senate Banking Committee Chairman Tim Scott to cancel a planned vote.
By May, a compromise emerged allowing activity-based rewards while prohibiting passive performance. As crypto.news reported, Armstrong supported the updated bill ahead of the Senate Banking Committee’s May 14 vote, which advanced the legislation 15 to 9. Despite this progress, Dimon’s comments on Friday indicated that JPMorgan and allied banks intend to push back the vote.
For Coinbase, the stakes are direct. Coinbase reported $1.35 billion in stable revenue in 2025, making yield provisions a revenue variable as much as a policy preference. Alex Thorn, director of Galaxy Research, currently estimates that the Clarity Act has a 70% chance of passing before the August holiday, while traders at Polymarket put it at 61%. Dimon’s public opposition, backed by the weight of America’s largest bank, adds institutional friction at precisely the moment when the bill’s floor schedule is most compressed.
