Shares of Cipher Digital (CIFR) jumped 7.3% to $18.85 on July 20 as the company's marquee contract — a $5.5 billion, 15-year lease with Amazon Web Services — entered its delivery phase. The capacity will be delivered in two phases, expected to begin in July 2026 and complete in the fourth quarter of 2026, with rent commencing in August 2026. With crypto markets flat, the move is almost entirely a bet on Cipher's reinvention as an AI power landlord.
Rent Checks Start in August, Ending a Revenue Drought. Cipher reported Q1 2026 revenue of $35 million, down from $60 million in Q4 2025, primarily due to the planned wind-down of Bitcoin mining operations. That dip left investors sitting through a painful construction phase. The next scheduled event, "AWS lease rent begins," is set for August 1, 2026. Once rent starts flowing on 300 megawatts of air- and liquid-cooled capacity, revenue should inflect sharply — the AWS contract alone averages roughly $367 million per year over its 15-year term.
$11.4 Billion in Signed Deals Shows the Pivot Is Real. Cipher has executed three long-term data center campus leases, generating approximately $11.4 billion of contracted revenue over the base lease terms. Those clients — AWS, Google-backed Fluidstack, and a third hyperscaler — represent locked-in demand that most mid-cap infrastructure companies would envy. The agreement marks a significant shift for Cipher Mining, which has been known primarily as a Bitcoin mining company.
Heavy Debt Is the Price of Transformation. Cipher generated $223.9 million in trailing twelve-month revenue, retaining a 63.7% gross margin, but operating income reached negative $421.6 million and net income was negative $822.2 million. To fund construction, the company piled on over $3 billion in project-level bonds and convertible notes. The majority of this debt is nonrecourse and tied to contracted assets, isolating risk and aligning debt with cash flow. That structure limits contagion if one project stumbles — but the 663% debt-to-equity ratio means any construction delay could punish the stock disproportionately.
The Stock Is Still Below Recent Highs, and Short Sellers Remain Skeptical. At a roughly $7.6 billion market cap, CIFR trades at less than one times its total contracted revenue — cheap if it executes. But short interest stands at 54 million shares, or 13.7% of the float, indicating notable bearish positioning.
BTIG recently raised its price target to $35 , but the stock sits more than 45% below that level. The gap between bull and bear cases is enormous: believers see a locked-in cash-flow machine; skeptics see a debt-laden builder that has yet to prove it can operate at hyperscale. August's first rent payment will be the first real test.
