On July 21, Cipher Mining rose 5.74% in regular trading, trading at $21.94/share, with turnover of $114 million. On the news front, Hut8 and IREN announced an AI infrastructure collaboration that triggered a collective surge across bitcoin mining stocks, with Cipher Digital, CleanSpark, Hut8, and MARA all posting gains exceeding 11% earlier in the session.

The core catalyst centers on concrete commercial milestones: Hut8 signed a 15-year lease agreement valued at $9.8 billion, while IREN disclosed cloud service contracts totaling $2.8 billion. Both former bitcoin mining companies are accelerating their pivot to AI infrastructure, with IREN projecting its AI cloud business annual recurring revenue to exceed $4 billion by year-end. Cipher Digital itself has been executing a similar transformation, having previously secured an $810 million senior secured notes offering and signed a 15-year hyperscale data center campus lease. However, analysts note the industry still faces a $50 billion capital gap to achieve its AI development targets, tempering long-term enthusiasm with near-term execution risk.
