‘No BlackRock, no party’ for Bitcoin, altcoin ETF investments: K33 Research
BlackRock was the only reason Bitcoin ETF investments didn’t turn negative in 2025, raising concerns for altcoin ETF performance without the asset manager.
The long-awaited approval of altcoin exchange-traded funds (ETFs) may not bring the massive inflows investors expect without participation from asset management giant BlackRock, according to market data.
BlackRock’s iShares Bitcoin Trust ETF accounted for over $28.1 billion of the total $26.9 billion inflows to US spot Bitcoin ETFs in 2025 so far.
Without BlackRock’s fund, the spot Bitcoin ETFs recorded a cumulative net outflow of $1.27 billion year-to-date (YTD), according to K33’s head of research, Vetle Lunde.
