According to @rovercrc, BlackRock bought $33,820,000 worth of ETH in an Aug 28, 2025 post on X (source: @rovercrc on X). The claim in the post does not cite an SEC filing, an official BlackRock issuer communication, ETF primary creation data, or an on-chain transaction hash for verification within the provided text (source: @rovercrc post content). Traders can seek confirmation by checking same-day creations/redemptions for the iShares Ethereum Trust (ETHA) and official notices from BlackRock, as well as updates on SEC EDGAR for any related disclosures (sources: BlackRock iShares website; SEC EDGAR). Until confirmed, monitor ETH spot-futures basis, funding, and open interest on CME, Binance, and OKX for unusual shifts that would be consistent with large buy programs (sources: CME Group market data; Binance and OKX public derivatives dashboards).
