According to @rovercrc, BlackRock has accumulated approximately 2.26 million ETH since May, outpacing all other ETFs by holdings growth (source: @rovercrc on X, Aug 26, 2025). For traders, if accurate, this scale of ETF-led accumulation signals sustained net inflows and supply absorption that can support positive spot bias and a tighter ETH futures basis (source: @rovercrc on X, Aug 26, 2025). Monitor daily ETF creations/redemptions, ETH exchange balances, and price behavior around liquidity zones to validate follow-through, as the “dominance” claim currently relies on a single-source post and awaits cross-verification via issuer disclosures or official filings (source: @rovercrc on X, Aug 26, 2025).
