Why Bitcoin Mining Stocks IREN, MARA, RIOT, HUT, CLSK Crashed Up to 23% Last Week

Five US-listed Bitcoin mining companies (IREN, MARA, CLSK, HUT, RIOT) saw significant declines (19-23%) last week due to hotter-than-expected US inflation data and AI sector concerns. IREN and MARA led the losses, with Morningstar and Cantor Fitzgerald lowering price targets. The selloff was driven by rising interest rate expectations and debt concerns in AI infrastructure.
