Cipher Mining is planning to raise $800 million through a private offering of 0.00% convertible senior notes due 2031, as it doubles down on its long-term crypto infrastructure strategy. The company, listed on Nasdaq as CIFR, also granted an option to purchase an additional $120 million in notes, bringing the potential total to $920 million.
The unsecured, zero-interest notes are convertible into cash, Cipher common stock, or a mix of both, depending on future conditions and shareholder approvals. Maturity is set for October 1, 2031, unless redeemed or converted earlier. Notably, the company has structured the deal to include capped call transactions, aimed at limiting shareholder dilution upon conversion while enhancing flexibility in settlement methods.
Proceeds from the raise are expected to support Cipher’s data center construction in Barber Lake, accelerate its high-performance computing (HPC) buildout across a 2.4 GW pipeline, and expand development across future mining sites. The company also intends to fund capped call transactions designed to hedge potential dilution linked to the conversion of the notes.
These plans are directly connected to a $3B AI hosting agreement with Fluidstack (Google-backed), making the capital raise as much about AI infrastructure as mining.
Google has reportedly committed to backstop $1.4B of lease obligations in that deal, and will receive warrants equal to ~5.4% equity.
Cipher’s debt strategy
Cipher operates industrial-scale Bitcoin mining and HPC hosting facilities, with a strategy focused on energy-efficient data centers and partnerships with large-scale computer providers. The company positions itself at the intersection of traditional infrastructure and digital assets—though in practice, it’s increasingly borrowing from Wall Street’s playbook to fuel crypto-native ambitions.
The $800 million convertible note offering follows a growing trend among miners using structured debt to tap capital markets. While the zero-coupon notes offer no yield or principal growth, they give investors leveraged exposure to Cipher’s equity, provided crypto markets cooperate.
The notes are being sold under Rule 144A to qualified buyers, with no registration planned. J. Wood Capital Advisors LLC served as Cipher’s financial advisor.
Despite the capital raise, market sentiment appears cautious as Cipher’s stock (CIFR) is down 10% today, September 25, according to TradingView.
While the company includes capped calls to limit dilution, those may not fully offset downside for existing holders if Bitcoin or AI revenue slows.
