Cipher Digital booked its first data-centre lease revenue in the third quarter, $5.9 million, and only $0.7 million of it went to cost of revenue, according to the results it filed with the SEC on Monday, 2 November. That left about 88% of the rent before other costs, by our arithmetic, against about 30% on the bitcoin it mined in the same quarter.
Cipher calls the new line high-performance computing (HPC) leasing. Its chief executive, Tyler Page, said the company’s “relationships with leading hyperscalers and AI labs are deepening”. Total revenue for the quarter was $26.7 million, down from $71.7 million a year earlier, when all of it came from bitcoin mining.
The key insight: Cipher Digital’s first quarter of data-centre rent brought in $5.9 million with $0.7 million of cost of revenue, leaving about 88% before other costs by our arithmetic, against about 30% on its bitcoin mining in the same quarter.
Cipher reported HPC leasing revenue of $5,852 thousand and HPC cost of revenue of $726 thousand for the quarter. That leaves $5,126 thousand, or 87.6% of the segment’s revenue, by our arithmetic.
Bitcoin mining brought in $20,849 thousand, with cost of revenue of $14,638 thousand. That leaves $6,211 thousand, or 29.8%, by our arithmetic. Put another way, cost of revenue took about 12 cents of each HPC dollar and about 70 cents of each mining dollar.
Both figures leave out depreciation and amortization, compensation and general and administrative costs, which Cipher reports on separate lines. HPC leasing made up 21.9% of total revenue in the quarter, by our arithmetic.

Where the Rent Comes From
The company said it “recognized its first HPC lease revenue following rent commencement at Black Pearl”. In its update on the hyperscaler-leased campuses, the shareholder presentation says first data-centre capacity was delivered in August, ahead of schedule, with 18 MW of critical IT capacity delivered to the tenant to date.
Cipher also highlighted an amendment to its Barber Lake lease that adds a second 10-year term “directly with a leading AI lab”. The amendment raises total contracted revenue at the site to approximately $9.1 billion, adding approximately $5.2 billion of incremental rent, the release says. The new rent is about 57% of the site’s total, by our arithmetic.
Across three campuses, Cipher’s presentation lists 700 MW of contracted capacity, a 17.3-year weighted average lease term, $16.6 billion of contracted revenue over the base terms and $28.4 billion including extensions. Its development pipeline totals approximately 5.9 GW, the release says.
How the Build Is Financed
The presentation lists $4,543 million of secured debt at the project companies as of 30 September: 7.125% senior secured notes at Cipher Compute LLC, 6.125% notes at Black Pearl Compute LLC and 6.000% notes at Stingray Compute LLC. Total debt was $6,700 million and net debt $3,079 million, on a basis that is pro forma for a later convertible issue.
After the quarter, Cipher completed an $850 million offering of 0.000% convertible senior notes due 2032, which funded additional equity investment into Barber Lake in connection with the lease expansion, the release says.
Business Pill · Gross Margin
A FourWeekMBA explainer on gross margin: what a company keeps from each dollar of revenue after the direct cost of delivering it.
Cipher’s presentation says it prioritizes “a long-term colocation model that delivers attractive risk-adjusted returns and durable cashflows”. What is new today is the first quarter of its own numbers on what that rent leaves after direct costs.
The Structural Read
As we read the release and presentation together, Cipher’s rent and its mining sit on very different cost lines: cost of revenue took about 12 cents of each HPC dollar and about 70 cents of each mining dollar in the quarter, by our arithmetic.
As we read the capital structure slide, the leases are financed at the project level, with senior secured notes at 6.000% to 7.125% across three subsidiaries, while the parent issued a 0.000% convertible due 2032.

Three Implications
FOR NEOCLOUD AND DATA-CENTRE INVESTORS Cipher lists 700 MW of contracted capacity, a 17.3-year weighted average lease term and $16.6 billion of contracted revenue over the base terms, according to its presentation.
FOR BITCOIN MINERS MOVING INTO AI Cipher’s quarter shows both lines side by side: $20.8 million of mining revenue and $5.9 million of HPC leasing revenue, with very different cost of revenue, according to its statement of operations.
FOR LENDERS TO THE BUILD-OUT The presentation lists $4,543 million of secured notes at three project companies, at 6.000%, 6.125% and 7.125%, as of 30 September.
The framework argues: “The $1T capex cycle is being underwritten by a $1T concentrated demand commitment from two counterparties whose combined free cash flow is deeply negative.”
As we read it, Cipher sits one step below that commitment: it builds and leases the data centres, and its Barber Lake amendment is directly with a leading AI lab, according to its release. The framework is the owner’s argument and does not discuss Cipher.
The 88% and 30% figures are revenue less cost of revenue only, not operating margins, and the HPC figure covers the first quarter of rent from a partial delivery. The margins are our arithmetic from Cipher’s statement of operations, not figures the company presents as margins.

This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
Cipher’s first quarter of data-centre rent brought in $5.9 million, with about 88% left after cost of revenue, by our arithmetic, against about 30% on bitcoin mining. The company lists $16.6 billion of contracted revenue across 700 MW of leases.
