Twelve months ago BUIDL was a $500M experiment. Today it's the most-collateralised tokenised treasury on the planet, dwarfing Ondo, Franklin and Hashnote combined.
BlackRock's BUIDL — the firm's tokenised US-treasury fund launched in March 2024 — has crossed 2.4 billion dollars in assets under management. The fund has roughly quintupled in twelve months, growing 18 percent month-over-month for the last quarter, and is now larger than every other tokenised treasury programme on the planet combined.
How the gap got this wide
Three reasons. First, BUIDL is the only tokenised treasury that institutional counterparties can post as collateral inside the largest DeFi venues — Aave, Maker, Sky — without bespoke onboarding. Second, BlackRock built distribution into the wrapper from day one: Coinbase, Circle and Securitize routes mean an allocator can mint or burn from almost any treasury workflow. Third, the yield is competitive with the underlying bills, after fees, which simply has not been true of most tokenised wrappers.
Ondo's OUSG, Franklin's BENJI, and Hashnote's USYC together hold roughly 600 million dollars. BUIDL alone is four times the rest of the field. That is not a tokenisation winner-take-all dynamic — it is a BlackRock-being-BlackRock dynamic. Distribution wins, and BlackRock distributes everything better than anyone.
The interesting number is not the 2.4 billion. It is the 18 percent monthly growth in the most boring asset class in finance.
What it pulls in next
The institutional treasury management market is roughly 5 trillion dollars in the US alone. Even a single-digit share of that flow rotating to a tokenised wrapper would put BUIDL at over a hundred billion. The yield differential to legacy treasury sweeps is not large, but the operational delta — 24/7 settlement, instant collateral mobility, programmable distributions — is decisive for the corporates that have already crossed the technology comfort line.
BUIDL passing 2.4 billion is no longer news because of the size. It is news because the growth rate is accelerating into a category that historically grows by single percentage points a year. Tokenised treasuries are inheriting the corporate-cash market in real time.
