JPMorgan's money fund grew 250% on Ethereum. Tether's free-money model looks thinner.
The size is still unclear, but the speed matters. Bank-issued yield products are learning to grow onchain before stablecoins can answer.

- →JPMorgan's JLTXX grew its onchain AUM by about 250% over the past month, according to Token Terminal data cited by The Defiant.
- →The fund launched on Ethereum on May 13, giving institutions a bank-issued yield product instead of idle stablecoins.
- →Watch whether Tether answers with a credible yield product before October, or keeps defending a model banks can copy.
- Tokenized money market fund → A traditional cash-like fund whose shares can move on a blockchain.
- Onchain AUM → The amount of assets in a product that can be tracked on a blockchain.
- Stablecoin float → The money stablecoin issuers make by investing reserves while users hold the coins.
250% is the number that matters here. JPMorgan's JLTXX grew its onchain AUM by about 250% over the past month, according to Token Terminal data cited by The Defiant. The fund, formally the OnChain Liquidity Token Money Market Fund, launched May 13 on Ethereum.
The caveat is important. We don't have an absolute AUM figure from the available brief, and the 250% number comes through one cited data source. But growth rate still tells you something. JPMorgan's bank-issued tokenized money fund is growing fast, on one chain, less than two months after launch.
That is uncomfortable for Tether. USDT works because users hold dollars that don't pay them yield, while Tether earns money on the reserves. That free-money model is huge when rates are high. It also gets weaker when banks offer a yield-bearing onchain cash product with their own name on the wrapper.
If you're holding stablecoins as working cash, the choice is getting cleaner. A tokenized money market fund is not a payment coin. It won't replace every use of USDT. But for institutions parking idle dollars, the math is simple. Yield beats no yield when access stops being painful.
The historical parallel is money market funds in the 1970s. Banks had deposits. Funds offered a better cash product when rates made the difference obvious. The old product did not vanish. It just stopped owning the whole cash relationship.
JPMorgan is not alone. BlackRock's BUIDL and Franklin Templeton's BENJI are already in the same tokenized money fund race. JLTXX matters because it shows another large bank can ship the product and grow it quickly, for now.
Tether's problem is not that JLTXX is already bigger. The brief doesn't show that. The problem is that the backing layer just got real, and bank products are moving faster than stablecoin issuers are sharing yield.
Tether is leaving idle dollars to JPMorgan and BlackRock unless it ships yield this quarter because banks can pay users.
By October 1, watch whether JLTXX adds another chain or tops 100% AUM growth from July levels.
