Cipher Mining is set to issue $333 million in 7.125% senior secured notes as part of its financing strategy, raising its 2030 plan to $1.733 billion. The funds will support the expansion of its Barber Lake data center in Texas, where it plans to lease the full 300 MW capacity to Fluidstack. This 10-year hosting agreement is projected to generate $830 million in revenue, with potential to reach $2 billion if renewed. The expansion will be funded by the note issuance and a $118 million equity contribution.
