BlackRock Eyes Blockchain Tokenization for Its ETFs

BlackRock is exploring tokenization of its exchange-traded funds (ETFs) on blockchain networks, following strong performance from its spot Bitcoin ETFs. The company's iShares Bitcoin Trust and iShares Ethereum Trust have attracted significant inflows, with $55 billion and $12.7 billion in cumulative inflows respectively.

The move could include funds with exposure to real-world assets and would potentially trade beyond traditional market hours. Tokenized ETF structures would also serve as collateral in DeFi applications, expanding utility beyond conventional investment vehicles.

BlackRock already manages the BUIDL fund across Ethereum, Avalanche, Aptos, and Polygon networks. The tokenized money market fund became the first such product to cross $1 billion in March 2025.
