BlackRock's BUIDL Reclaims Top Spot for Tokenized Treasuries, Bolstering RWA Market

BlackRock’s USD Institutional Digital Liquidity Fund (BUIDL) has reclaimed its position as the largest tokenized U.S. Treasury fund, reaching a market capitalization of approximately $2.8 billion. Data from Token Terminal indicates that BUIDL now commands roughly 18.5% of the $15.1 billion total tokenized Treasury market. This shift follows a brief period where Circle’s USYC fund held the lead, having grown from $600 million to nearly $3 billion over the past year. The rapid exchange of the top spot between these two major products highlights intense institutional competition and active product evaluation within the sector. By utilizing blockchain technology, these funds enable 24/7 settlement for short-term government debt, offering a significant efficiency upgrade over traditional multi-day bond market cycles. This ongoing rivalry suggests that the tokenized Treasury market is maturing beyond its early-mover phase into a highly contested financial category. The sustained growth in these assets signals a broader institutional appetite for on-chain yield-bearing collateral that may eventually expand into other asset classes.
