‘Banksters Are Out To Kill Crypto,’ Tyler Winklevoss Slams JPMorgan

The debate over who should control—and pay for—access to US consumers’ banking data turned acrimonious after Gemini co‑founder Tyler Winklevoss claimed that JPMorgan Chase & Co. is “trying to kill fintech and crypto companies.” In an extended X thread posted late Sunday, Winklevoss charged that the nation’s largest bank wants “to take away your right to access your banking data for FREE via third‑party apps like Plaid and instead charge you and fintechs exorbitant fees.”

He warned that the proposed tolls would “bankrupt fintechs that help you link your bank accounts to crypto companies like Gemini, Coinbase, and Kraken so you can easily fund your account w/ fiat to buy bitcoin and crypto.”

Winklevoss’ broadside landed ten days after Bloomberg first disclosed that JPMorgan has distributed price sheets to data aggregators outlining usage‑based fees for application‑programming‑interface (API) calls that move customer data to external apps. Reuters subsequently confirmed the plan and published the bank’s initial defense: “We’ve invested significant resources creating a valuable and secure system that protects customer data. We’ve had productive conversations and are working with the entire ecosystem to ensure we’re all making the necessary investments in the infrastructure that keeps our customers safe.”

The timing is delicate. Last October the Consumer Financial Protection Bureau (CFPB) finalized its Personal Financial Data Rights Rule under Section 1033 of the Dodd‑Frank Act, requiring banks to hand over a customer’s checking and credit‑card data—at no cost—whenever the customer asks a third party to retrieve it.

Hours after the rule’s release, the Bank Policy Institute and the Kentucky Bankers Association sued the CFPB in federal court, arguing that regulators had exceeded their authority and jeopardized data security. The case is pending in Lexington, but under the Trump administration the CFPB has taken the unusual step of telling the judge that the rule it wrote “should be vacated,” a reversal that critics say emboldened JPMorgan to move ahead with a pay‑to‑play model.

JPMorgan chief executive Jamie Dimon insists the fees simply recoup infrastructure costs. “It costs a lot of money to set up the APIs and stuff like that to run the system,” he told analysts on last week’s earnings call, adding that third parties “should pay for accessing the banking system and payment rails,” according to Payments Dive.

The clash has spilled into crypto‑political circles. Winklevoss argued that the banks’ lawsuit “undercut President Trump’s mandate to make America the pro‑innovation and the crypto capital of the world.” Attorney John E. Deaton echoed the sentiment, recalling that he “put the majority of my wealth” into digital assets after Dimon called Bitcoin a fraud and labeling the JPMorgan chief “Public Enemy #1.”

Deaton also highlighted JPMorgan’s historical compliance fines, asserting that the bank “has been fined $40 billion across 281 violations since 2000.” Venture capitalist and presidential Crypto Czar David Sacks summed up the controversy in a single word: “Concerning.”

Behind the rhetoric lie concrete stakes for crypto exchanges, which rely on Plaid, MX, Yodlee and similar gateways to verify customer accounts and pull in fiat. If data aggregators absorb new fees, they are expected to pass at least part of the cost to high‑frequency users—including exchanges that automate cash sweeps—raising onboarding friction just as US regulators are inching toward clearer securities guidance for digital‑asset platforms.
