Jane Street Invests Heavily in Bitcoin Mining, Boosting Stocks

Financial powerhouse Jane Street significantly expanded its crypto portfolio by disclosing stakes of 5% or more in major Bitcoin mining companies like Cipher Mining, Hut 8, and Bitfarms. This move has sent stock prices soaring. The disclosure signals a surge in institutional interest in the Bitcoin mining space, enhancing market confidence and aligning with growing trends towards AI integration in cryptocurrency infrastructure. Jane Street’s SEC Schedule 13G filings on October 24, 2025, revealed their acquisition of substantial stakes (over 5%) in these firms. This bold move reflects a substantial shift in market dynamics, according to analysts.
