Jamie Dimon runs the largest bank in the United States. He oversees $3.9 trillion in assets, employs over 300,000 people, and sits on the boards of organizations that shape global financial policy. He is, by any measure, one of the most powerful figures in American finance. And on May 29, 2026, speaking on Fox Business with Maria Bartiromo, he publicly called the CEO of a publicly traded company “full of sh!t” on national television.
The target was Brian Armstrong, CEO of Coinbase. The subject was the CLARITY Act. And the outburst was not a slip. It was the second time Dimon had said it to or about Armstrong in 2026. The first was in January at Davos, where he told Armstrong directly, face to face, in what sources described to the WSJ as a private exchange: “You are full of sh!t.” Four months later, he said it again, this time on cable television with millions watching.
What Dimon Actually Said, Word for Word
Speaking on Fox Business on May 29, Dimon was asked whether he was happy with how the CLARITY Act was shaping up. “No,” he said. “The banks will not accept it that way.” He then escalated: “It will be fought. No one is going to bow down to this guy, or that company.” When Fox Business anchor Maria Bartiromo specifically asked about Coinbase, Dimon went further: “He’s the only one… he’s spending hundreds of millions of dollars in Washington on this thing. He’s full of sh!t.”
That was the public version. The private version came earlier. During meetings at the World Economic Forum in Davos in January, Dimon told Armstrong directly: “You are full of sh!t,” according to people familiar with the exchange. That confrontation was reported by the WSJ and subsequently confirmed by multiple outlets. Armstrong had been approaching Wall Street executives at Davos to make the case against what he described as bank lobbying to kneecap crypto features in the CLARITY Act. Dimon’s response was unambiguous.
Dimon also added: “We’ll fight it. If we lose, we lose, and we’ll live. But it will be fought.”

Maria: “…well.”
Armstrong’s Response: A Hockey Meme
Hours after the Fox Business interview aired, Brian Armstrong posted a hockey-themed rivalry meme on X. No statement. No press release. No legal threat. Just a meme. Whether that reads as confidence, restraint, or strategic silence ahead of the Senate floor vote is a matter of interpretation. No formal comment from Coinbase had surfaced as of publication time.
What the Fight Is Actually About: One Word in One Clause
The dispute that produced a sitting bank CEO calling his counterpart a profanity on national television is, technically, about a single word in the CLARITY Act’s stablecoin provisions. The contested language determines whether stablecoin issuers can pay yield-like rewards on customer balances. Dimon’s argument is that if a company accepts customer funds and pays returns on them, it is functionally operating a deposit-taking institution, and it should be regulated like one, subject to the same capital requirements, AML and BSA compliance, liquidity standards, and consumer protection obligations that JPMorgan operates under.
“If he takes deposits like a bank, he should have bank rules,” Dimon said, referring to Armstrong and crypto platforms broadly. His framing presents this as a fairness argument. If banks must hold capital, maintain liquidity ratios, report suspicious transactions, and submit to quarterly examination cycles, so should anyone doing equivalent things with customer money.
Armstrong’s counter-argument is equally direct. Coinbase has framed the banking lobby’s opposition to stablecoin yields as regulatory capture: incumbent institutions using their political influence to prevent a competitive threat from reaching consumers. The CLARITY Act cleared the Senate Banking Committee on May 14 in a 15-9 vote. But Dimon’s escalation signals that clearing committee is not the same as clearing the Senate floor, where 60 votes are needed to break a filibuster and every banking lobby dollar now has a target.

What JPMorgan Is Actually Building on Ethereum While Dimon Talks
While Dimon was on Fox Business calling Armstrong names, JPMorgan’s blockchain division was processing between $5 billion and $7 billion in daily transaction volume. That is not a typo. Kinexys, formerly Onyx, JPMorgan’s permissioned blockchain platform, has grown from $2 billion per day at its November 2024 rebrand to a target of $10 billion per day, with cumulative volume since launch exceeding $3 trillion. Most of JPMorgan’s own clients have never heard of it.
Kinexys runs several products. JPM Coin enables 24/7 real-time dollar and euro transfers between institutional accounts, including weekends, eliminating the settlement delays Dimon complains about when describing legacy correspondent banking. The Tokenized Collateral Network allows institutions to move and pledge collateral in seconds rather than days. An on-chain FX product provides continuous liquidity for major currency pairs. And on May 12, one week before Dimon’s Fox Business interview, JPMorgan filed JLTXX with the SEC, its second tokenized Treasury fund on Ethereum, powered by Kinexys and explicitly designed to serve stablecoin issuers’ GENIUS Act reserve requirements.

The detail that sharpens the irony to a fine point: JPM Coin has been issued on Base, the Ethereum Layer 2 network built by Coinbase. The man Dimon called “full of sh!t” on national television runs the company whose blockchain infrastructure JPMorgan uses to operate one of its own digital currency products.
The Hypocrisy Argument Coinbase Will Not Let Go
The banking lobby’s regulatory fairness argument would be easier to take seriously if JPMorgan were not simultaneously building its own blockchain infrastructure. Dimon acknowledged in the same Fox Business interview that blockchain is a “legitimate technology” and noted that JPMorgan already operates JPM Coin and deposit token systems aimed at institutional settlement. The bank runs Kinexys, its tokenization platform, which powered JLTXX, its GENIUS Act-compliant tokenized Treasury fund filed with the SEC on May 12. A week before calling Armstrong “full of sh!t,” JPMorgan filed to become exactly the kind of stablecoin-adjacent institution it is now claiming should face heavier regulation.
That tension is not lost on anyone watching the fight. Coinbase’s argument is essentially: JPMorgan wants the regulatory framework tight enough to block crypto companies from competing on deposit-like products, while keeping it loose enough for JPMorgan’s own blockchain products to operate. Dimon’s public broadside against Armstrong signals the banking lobby views crypto’s political machine as a genuine threat, not just a nuisance. And the numbers support that reading. Coinbase’s super PAC poured record sums into congressional races in the 2024 election cycle. The political influence gap between banks and crypto has narrowed faster than anyone in traditional finance expected.
What Dimon’s History With Bitcoin Tells You About This Fight
Jamie Dimon called Bitcoin a “fraud” in 2017. He called it a “pet rock” in 2024. He said in 2021 that he personally had no interest in it and that its value was “supported by nothing.” At the same time, JPMorgan became one of the authorized participants for BlackRock’s IBIT Bitcoin ETF, processed billions in crypto-related transactions for institutional clients, and built Kinexys, its own blockchain platform, now processing over $1 billion in daily transaction volume.
The pattern is consistent: Dimon dismisses crypto in public while JPMorgan builds crypto infrastructure in private. The public dismissals serve a regulatory purpose. If JPMorgan’s CEO is on record calling Bitcoin worthless and crypto dangerous, the bank is better positioned to argue for tighter crypto regulation that protects its existing business lines. The private buildout serves a commercial purpose. If crypto wins, JPMorgan intends to be the infrastructure layer on which it runs.
A compromise in the CLARITY Act’s May draft prohibits passive rewards, meaning interest-like payments simply for holding a stablecoin parked in a wallet, while permitting activity-based incentives tied to actually using the stablecoin for transactions or other engagement. Whether that distinction satisfies Dimon is clearly no. His Fox Business comments came after that compromise was already brokered. The banks are not fighting a specific clause. They are fighting the bill’s entire direction of travel.
What Happens Next: 60 Votes, 60 Days
The CLARITY Act cleared the Senate Banking Committee 15-9 on May 14. It now faces a Senate floor vote where 60 votes are needed to overcome a filibuster. The White House has set a July 4 target for presidential signature. Senator Gillibrand projects early August. Polymarket has signing odds at around 60%.
Dimon’s intervention matters because JPMorgan’s lobbying reach extends to senators in both parties who depend on banking industry support. The American Bankers Association, community banks, and credit unions are all aligned with Dimon’s position. That coalition covers a lot of Senate districts. Every senator who needs banking industry goodwill for their next election cycle now knows where the most powerful banker in America stands, and he said it in the most memorable way possible.
Armstrong has not publicly responded to the most recent remarks as of publication time. No comment from Coinbase has surfaced since the Fox Business interview. That silence may be strategic. The Senate floor is where this is decided, not cable television. Armstrong has already spent what Dimon estimates as hundreds of millions of dollars in Washington. The real question now is whether that spending has already locked enough votes to get to 60, or whether Dimon’s very public tantrum just reminded enough wavering senators which side the oldest money in American finance is on.
Frequently Asked Questions
What did Jamie Dimon actually say about Brian Armstrong?
Dimon made the comment twice. First at the World Economic Forum in Davos in January 2026, telling Armstrong directly in a private exchange: “You are full of sh!t,” according to sources familiar with the conversation reported by the WSJ. Second, on May 29, 2026, live on Fox Business’s Mornings with Maria, Dimon said of Armstrong: “He’s the only one… he’s spending hundreds of millions of dollars in Washington on this thing. He’s full of sh!t.” Both incidents concern Armstrong’s lobbying efforts in support of stablecoin yield provisions in the CLARITY Act.
What is Dimon’s specific objection to the CLARITY Act?
Dimon’s objection is that the CLARITY Act as written allows stablecoin issuers to effectively pay interest on customer deposits without facing the same capital requirements, AML and BSA compliance obligations, and consumer protection standards that chartered banks must meet. His argument is structural: anyone taking in customer funds and paying returns on them is functionally a deposit-taking institution and should face equivalent regulation. He also argues that without these requirements, stablecoin products offering yield could eventually fail in ways that cause systemic problems.
Is JPMorgan building its own blockchain products while fighting crypto regulation?
Yes. JPMorgan operates Kinexys, formerly Onyx, its blockchain and tokenization platform processing over $1 billion in daily institutional transaction volume. It filed the JLTXX tokenized Treasury fund with the SEC on May 12, designed specifically to comply with GENIUS Act stablecoin reserve requirements. It is an authorized participant in BlackRock’s IBIT Bitcoin ETF. Dimon’s public skepticism about crypto and private buildout of crypto infrastructure are both consistent and long-running. Critics describe it as regulatory positioning: oppose crypto rules that threaten banking margins while building blockchain products that would benefit from a framework JPMorgan helps shape.

One week before calling Armstrong “full of sh!t,” JPMorgan filed its second blockchain product with the SEC. The two moves are not contradictory. They are the same strategy.
While Dimon fights to slow crypto firms getting banking access, Augustus Bank just received an OCC full national bank charter for a stablecoin-native clearing bank. The thing Dimon says crypto can’t have is being granted by his own former regulator.
