The BlackRock BUIDL fund has a size of nearly $3 billion, doubling in the past 90 days

ChainCatcher news, according to Cryptoslate, BlackRock's dollar institutional digital liquidity fund (BUIDL) expanded by approximately $1 billion from March 26 to June 11, accounting for about half of the $2 billion growth in the tokenized U.S. Treasury market during the same period.

As of now, according to data from rwa.xyz, the size of BUIDL has reached $2.89 billion, making it the largest tokenized money market fund, representing 40% of the $7.34 billion market. March 26 is a significant date, as on that day EthenaLabs stopped increasing its holdings in the stablecoin USDtb's fund shares. Most of the growth of BUIDL in 2025 comes from USDtb, with 90% of the reserves, totaling $1.3 billion, injected into the fund. Even without the push from Ethena, BUIDL achieved a significant 35% growth in less than three months, highlighting the strong demand for regulated high-yield cash instruments on public blockchains.

Additionally, since the fund reached $1 billion on March 13, its size has nearly tripled. However, the fund expanded to three times its original size in less than 90 days, indicating a surge in market interest in the tokenization of real-world assets (RWA), especially tokenized U.S. Treasuries.
