BlackRock’s tokenized Treasury fund, BUIDL, grew its market cap by $52.1 million in just 24 hours, reinforcing its position as the dominant player in a sector that barely existed two years ago.
The fund, formally known as the BlackRock USD Institutional Digital Liquidity Fund, has become the benchmark product in the tokenized US Treasury market. That market now sits somewhere between $15 billion and $16 billion in total on-chain value, and BUIDL commands a significant chunk of it with a market cap typically ranging from $2.5 billion to $2.7 billion.
From zero to billions in under three years
BUIDL launched in March 2024 and wasted very little time finding its audience. The fund crossed $500 million in assets under management by mid-2024. By late 2025, the fund had distributed over $100 million in cumulative dividends to holders. It then continued climbing past the $2 billion mark by late 2026.
The fund maintains a net asset value of roughly $1 per token, with daily yield accrual in the 3-5% APY range. The underlying assets are short-term US Treasuries and cash equivalents, packaged into a regulated vehicle that settles on-chain around the clock.
Traditional Treasury products operate within market hours and settle on T+1 timelines. BUIDL offers instant settlement at any hour, which turns out to be exactly what institutional investors want when they’re managing liquidity across global portfolios.
Why institutions keep showing up
The $52.1 million daily increase wasn’t an anomaly. In a recent seven-day period around mid-August 2026, BUIDL added $32.5 million in market cap, suggesting the larger single-day jump represents an acceleration rather than a one-off event.
Traditional money market funds offer similar yield profiles, but they come with settlement delays, limited operating hours, and the friction of moving between on-chain and off-chain environments. BUIDL eliminates that friction by keeping the entire lifecycle on-chain, from purchase to redemption to yield distribution.
Data from Token Terminal suggests BUIDL’s growth is part of a broader surge in tokenized Treasury products.
The gap between potential and adoption
For all its growth, the tokenized Treasury sector still faces a notable constraint. Utilization of these products within DeFi lending protocols remains relatively low.
The competitive landscape is also getting more crowded. Franklin Templeton, Ondo Finance, and other issuers have launched their own tokenized Treasury products, each targeting slightly different investor profiles and chain ecosystems.
A $15-16 billion tokenized Treasury market sounds large until you compare it to the roughly $6.7 trillion US Treasury market. The on-chain version represents a fraction of a fraction.
