JPMorgan’s Jamie Dimon Slams Coinbase’s Brian Armstrong, Signals Opposition to Clarity Act
JPMorgan Chase CEO Jamie Dimon is making it clear he intends to fight the CLARITY Act, and he is not holding back about who is on the other side of that fight. In a Fox Business interview on Friday, Dimon vowed to fight the CLARITY Act, calling Coinbase CEO Brian Armstrong “full of sh–” over his lobbying push for the legislation.
At the heart of Jamie Dimon’s decision to fight the CLARITY Act is a single contentious provision: stablecoin yield. The CLARITY Act would allow crypto firms to reward customers for holding stablecoins, something banks argue creates direct competition without requiring the same consumer protections banks must follow. Dimon also raised concerns about the bill’s Anti-Money Laundering and Bank Secrecy Act provisions, describing them as insufficient. “It allows cryptocurrency firms to effectively pay interest on deposits, stablecoins or something like that, without the protection that they should have,” he said. “The banks will not accept it that way.”
Despite his strong opposition, Dimon said he is not against blockchain or stablecoins outright, and acknowledged their potential value in cross-border payments. His fight is specifically with the way the current legislation is structured. “It’s complicated. The government needs to do it thoughtfully. If they don’t do it thoughtfully, it will be a huge problem,” he added.
Beyond the policy fight, Dimon went after Armstrong directly, claiming the Coinbase CEO is spending hundreds of millions of dollars in Washington to push the legislation over the finish line. “No one is going to bow down to this guy,” Dimon said. The remarks follow similar comments Dimon made about Armstrong at the World Economic Forum in Davos earlier this year, indicating the tension between the two executives goes well beyond this single bill.
Armstrong fired back on social media with a hockey-themed meme that quickly drew backing from across the crypto industry. The viral exchange on Friday turned a regulatory fight over stablecoin rewards into a rallying moment for digital asset leaders pushing the bill to the Senate floor. Galaxy Digital’s Mike Novogratz argued that elected lawmakers, not banks, should be writing financial laws. Coin Center’s Peter Van Valkenburgh pushed back on Dimon’s AML framing, pointing out that roughly $3 trillion was laundered through banks in 2025.
The stakes around the CLARITY Act are rising fast. The stablecoin yield debate has become the most contested issue around the bill, with nine weeks left before the August recess creates a hard deadline. Galaxy Digital Head of Research Alex Thorn gives the bill 70% odds of passing while Polymarket traders sit at 61%. But Dimon’s decision to publicly fight the CLARITY Act adds serious institutional banking weight to the opposition at a critical moment. If banks succeed in watering down or killing the stablecoin yield provision, the direct consequences fall on crypto exchanges and stablecoin issuers who had been counting on that revenue stream.
For context, some in the crypto industry have begun drawing comparisons between Coinbase and Charles Schwab’s disruption of brokerage commissions in the late 1970s, framing the current fight as another chapter in the long battle between Wall Street incumbents and financial challengers.
