Cipher Mining Inc. surged 23.27% in premarket trading following the announcement of a $5.5 billion, 15-year lease with Amazon Web Services to deliver 300 MW of AI infrastructure capacity in 2026, along with a 95% equity stake in a 1-GW West Texas joint venture. The AWS agreement, including air and liquid cooling capabilities, and the Colchis site development, underscored significant long-term revenue visibility and strategic positioning in the AI and HPC sectors. Additionally, analysts from H.C. Wainwright and Rosenblatt raised price targets to $25, citing strong Q3 Bitcoin growth and operational expansion. These developments, combined with $8.5 billion in contracted AI hosting payments and a $1.3 billion convertible note offering, reinforced investor confidence in Cipher’s capitalizing on the AI infrastructure boom.
