The ranking has changed over time, so the September lead should not be written as a permanent outcome. The underlying Treasury-token segment itself can expand or contract as yield and crypto collateral demand change.
Minimums Shape Who Can Subscribe
Reported access thresholds differ sharply: USYC has a $100,000 minimum for eligible non-US persons, while BUIDL's disclosed minimum is $5 million for qualified purchasers.
Those thresholds are not a like-for-like retail comparison. USYC's offshore eligibility and BUIDL's qualified-purchaser restrictions narrow the buyer pool in different ways, and actual access depends on current offering documents, intermediary onboarding and jurisdiction.
Circle describes USYC access for non-US persons; the BlackRock launch announcement stated a $5 million minimum for BUIDL.

Lower minimums can widen potential distribution, but do not guarantee greater adoption. Custody, permitted jurisdictions, investor servicing and transfer controls still determine whether eligible buyers can participate.
Yield Mechanics Affect On-Chain Use
USYC's value accrues as the token price rises with yield, a structure Circle says embeds returns in the token rather than requiring a separate distribution claim.
That can simplify accounting for applications that need a yield-bearing balance as collateral, but it does not make the token universally composable. Integrations still need a supported transfer path, a price source and legal authority to control the asset on default.
A product's collateral role also depends on where institutions can hold it. Circle announced support for USYC as off-exchange collateral for Binance institutional clients; eligibility and platform-specific terms remain material.
Market Share Is Not the Same as Addressable Demand
AUM ranking measures outstanding tokens, not unique investors, net new flows or the amount each fund can serve under its eligibility rules.
RWA.xyz's September view also placed USDY close behind at about $2.249 billion, showing that the segment is not a two-product market. Several issuers compete for different geographies, custody routes and collateral use cases.
An issuer should track assets, holders, transfer activity and collateral integrations separately. Our guide to tokenized funds as stablecoin reserve assets explains why legal classification can narrow the practical market even when a token is liquid.
Compare Funds by the Rail the Buyer Needs
For an institutional buyer, the useful comparison is not only USYC versus BUIDL AUM; it is which fund the buyer may legally acquire, custody, transfer and pledge under its operating model.
- Confirm investor eligibility, minimums and jurisdiction from current documents.
- Map where yield appears: token price, distributions or another process.
- Verify redemption and settlement timelines rather than assuming 24/7 cash access.
- Check whether intended custodians, venues and collateral counterparties support the token.
USYC's September 2026 lead over BUIDL is real for that dashboard snapshot. Its durability depends on how well each fund fits the buyer's legal and collateral rails—not on the ranking alone.
