BlackRock’s BUIDL Fund Surges 129% in 30 Days, Reaching $1.4 Billion

BlackRock’s tokenized US Treasury fund, BUIDL, has seen a significant surge in adoption, with its assets under management (AUM) reaching nearly $1.5 billion. This growth underscores a broader trend toward real-world asset (RWA) tokenization, even as the broader crypto markets face challenges. According to data, BUIDL’s AUM has increased by almost 129% over the last 30 days, bringing it to $1.4 billion. This milestone means that it took only one year for the fund, which launched on the Securitize platform in March 2024, to cross the $1 billion mark. The majority of BUIDL’s supply—over $1 billion, or 86.46%—remains on Ethereum, indicating strong minting activity on the network. Other chains, such as Avalanche and Aptos, each hold about $56 million of the fund’s supply, or roughly 3.6%. Ethereum Layer-2 networks like Polygon, Arbitrum, and Optimism host the rest.

Investor participation has also grown. In the past month, the number of holders rose by 19%, bringing the total to 62. Market observers pointed out that these numbers highlight the growing trust in blockchain-based financial products and the rising institutional interest in tokenizing bonds and credit. This trend is further evidenced by Fidelity’s recent move into the tokenization space. Over the past week, the firm filed with the US Securities and Exchange Commission (SEC) to launch a blockchain-based version of its Treasury money market fund. The new share class, named “OnChain,” will operate using blockchain as a transfer agent and settlement layer. Fidelity’s move mirrors a broader trend where financial institutions are turning to blockchain to tokenize bonds, funds, and credit instruments. This shift offers improved efficiency, round-the-clock settlement, and better transparency.

Meanwhile, the filing comes as institutional interest in RWAs continues to rise, despite a sluggish crypto market. While Bitcoin is down 11% year-to-date, RWA tokens have seen sustainable growth in 2025. On-chain data shows the total RWA market has grown 18.29% in the past 30 days, reaching $19.23 billion. The number of RWA holders also increased by 5%, now nearing 91,000. BlackRock’s BUIDL leads the RWA space by market cap. It’s followed by Hashnote’s USDY at $784 million and Tether Gold (XAUT) at $752 million. US Treasuries make up $4.76 billion of the total, while private credit dominates with $12.2 billion.

This surge in adoption and the entry of major players like Fidelity and BlackRock into the RWA tokenization space indicate a growing acceptance and trust in blockchain-based financial products. The trend towards tokenization is driven by the benefits it offers, including improved efficiency, round-the-clock settlement, and better transparency. As more institutions enter this space, it is likely that we will see further growth and innovation in the RWA tokenization market. The increasing number of holders and the growing AUM of funds like BUIDL suggest that investors are becoming more comfortable with the idea of tokenizing real-world assets, despite the challenges faced by the broader crypto market.
