According to @FarsideUK, BlackRock’s US Ethereum ETF recorded 639.8 million USD in daily flow on the latest reading, as reported on Farside’s Ethereum ETF flow dashboard (source: Farside Investors tweet and farside.co.uk/eth). Under the fund’s structure, creations resulting from positive flows lead the sponsor to acquire additional ETH to back new shares, increasing spot demand at the margin (source: BlackRock iShares Ethereum Trust prospectus, SEC filing). Traders monitor these ETF flow prints because creations and redemptions handled by authorized participants directly translate into underlying ETH purchases or sales for the fund, impacting spot market liquidity (source: BlackRock iShares Ethereum Trust prospectus, SEC filing).
