BlackRock and Fidelity's ETFs, including IBLC, FDIG, and DAPP, have strategically shifted their focus towards Bitcoin miners that have successfully transitioned to high-performance computing (HPC) for AI applications. This move comes as the profitability of traditional Bitcoin mining declined in 2025. Notable investments include IREN Ltd, Hut 8 Corp, and Applied Digital, with significant holdings across these ETFs. Hut 8 Corp, in particular, saw a remarkable 124% increase in value over the year, highlighting the success of this pivot. The ETFs' strategy of leveraging energy and compute resources has allowed them to outperform the S&P 500, although they slightly lagged behind ARKF due to the absence of high-growth stocks like Palantir and Robinhood.
