BUIDL is the largest tokenized treasury fund on-chain, at roughly $2.5B in AUM. It is also one of the most misunderstood: most of the people searching for how to buy it cannot, and the interesting question is what they should look at instead.
Key Takeaways
- BUIDL requires Qualified Purchaser status and a $5M minimum subscription through Securitize. There is no retail path to direct ownership.
- The fund holds cash, US Treasury bills, and repo, targets a stable $1 NAV, and pays yield as daily dividend accruals distributed monthly in new tokens.
- For allocators under the minimum, the tokenized treasury category now spans $7B+ across funds with materially lower entry points. The access question matters more than the brand.
Background
BlackRock launched BUIDL in March 2024 with Securitize as transfer agent and placement agent. It has since grown past $2.4B in AUM, around 40% of the tokenized treasury market, and expanded from Ethereum to multiple chains including Avalanche, Polygon, and Solana. Holdings sit in T-bills and overnight repo. The token is a share of a regulated fund, not a stablecoin, although DeFi increasingly treats it as collateral infrastructure.
Analysis
The actual purchase path
Direct subscription runs through Securitize Markets. The requirements are strict: Qualified Purchaser status under US securities law, meaning at minimum $5M in investments, a $5M minimum initial subscription, and full KYC and AML onboarding. Token transfers only settle between whitelisted addresses. There is no DEX route to compliant ownership, and wrapped or synthetic versions of BUIDL carry their own counterparty and legal questions that the fund's compliance model exists to avoid.
Who actually buys it
Crypto-native institutions parking operating treasury, market makers posting it as yield-bearing collateral, protocols backing stablecoins with it, and funds that want T-bill yield without leaving their on-chain operational stack. Ondo's OUSG, for example, holds BUIDL as a core asset and resells access at a lower minimum. That layering, funds holding funds, is how BUIDL's yield reaches most of the market.
If you are under the minimum
The category is wider than the flagship. Tokenized treasury products from Ondo, Franklin Templeton, Superstate, and others run minimums from $5K to $100K with different eligibility rules per issuer. Yields cluster near the front-end T-bill rate minus fees. The comparison that matters is eligibility, redemption mechanics, and chain support, not headline brand.

Implications
BUIDL's real significance is not as a product most allocators will buy. It is the proof that the largest asset manager in the world treats on-chain settlement as production infrastructure, and it anchors the collateral layer a lot of composable strategies are starting to build on. RWA yield as one leg, funding or basis as the other. Watching where BUIDL plugs in next tells you where that stack is going.
Risk Considerations: Tokenized fund shares are securities with issuer-level eligibility restrictions. Geofencing applies at the issuer level. Check the prospectus before sizing.
