Coinbase CEO Brian Armstrong posted a hockey-themed rivalry on X on Friday, hours after JPMorgan Chase CEO Jamie Dimon appeared on Fox Business. Morning with Maria He called Armstrong “full of shit” for his lobbying efforts for the Digital Assets Market Clarity Act.
The exchange has escalated a months-long public spat between the head of Wall Street’s biggest bank and the most prominent CEO of a cryptocurrency exchange, which now centers on one sticking point: whether crypto platforms should be allowed to pay yield on stablecoin balances without being subject to bank-style regulation.
What did Damon say and what does he mean?
Appearing on Fox Business on May 29, Damon He said: “It allows crypto companies to effectively pay interest on deposits or stablecoins or something like that, without the protection they should have. Banks won’t take it that way.” He warned that the system would “eventually explode” 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,” Damon said.
Mike Novogratz, CEO of Galaxy Digital, joined in the response to X, writing: “Since when can banks decide on regulation?” Novogratz argued that lawmakers, not financial institutions, should set the framework for digital assets.
The friction between Damon and Armstrong is not new. At the World Economic Forum in Davos in January 2026, Dimon reportedly told Armstrong directly: “You’re full of stuff!” In a private meeting that also included former UK Prime Minister Tony Blair. “If you want to be a bank, just be a bank,” Bank of America CEO Brian Moynihan reportedly told Armstrong in Davos. Coinbase withdrew its support for the Clarity Act in January after the Senate draft included provisions that would have effectively banned returns on stablecoin balances, a withdrawal that forced Senate Banking Committee Chairman Tim Scott to cancel the scheduled vote.
By May, a compromise emerged that allowed activity-based rewards while prohibiting passive returns. like crypto.news reportedArmstrong backed the updated bill ahead of a Senate Banking Committee vote on May 14, which advanced the legislation 15 to 9. Despite this progress, Dimon’s comments on Friday indicated that JPMorgan and its allied banks intend to back away from the vote.
For Coinbase, the risks are straightforward. Coinbase reported $1.35 billion in stablecoin revenue in 2025, making yield allocations as much a revenue variable as policy preferences. Galaxy Research President Alex Thorn is currently giving the Clarity Act a 70% chance of passing before the August recess, while Polymarket traders are pricing it at 61%. Dimon’s public opposition, backed by the weight of America’s largest bank, adds institutional friction precisely at the moment when the bill’s timeline becomes most compressed.
