Cipher books its first data-center rent as bitcoin mining revenue shrinks

A company that built its business mining bitcoin now collects rent. Cipher Digital, formerly Cipher Mining, said on Monday that it "recognized its first HPC lease revenue" in the third quarter, money from tenants renting space and power for high-performance computing, the heavy-duty processing that needs dense power and cooling [2]. The amount was small. The direction is the story: the same quarter, its bitcoin mining revenue fell by more than two-thirds.

The results came in a Form 8-K filed with the Securities and Exchange Commission and accepted at 7:17 a.m. EST, with the press release attached as Exhibit 99.1 [1][3].

The mechanism

Bitcoin miners and large computing data centers want the same scarce things: large plots of land, cheap electricity and permission to connect to the power grid. A miner that already has those can stop running its own machines and lease the space to someone else, a model known as colocation, where the landlord supplies the building, power and cooling and the tenant brings the computers.

The economics differ sharply. Mining revenue moves with the bitcoin price and the network's competition. Lease revenue is set by contract for years. Cipher says its tenant at its Barber Lake site signed an amendment that "adds a second 10-year term directly with a leading AI lab," lifting "total contracted revenue at the site to approximately $9.1 billion" and "adding approximately $5.2 billion of incremental rent" [2]. That is revenue promised over two decades, not revenue earned. Across all its leases, Cipher's investor presentation, filed as Exhibit 99.2, counts "700 MW Contracted Gross HPC Capacity" and "$16.6 Bn Contracted Revenue," or $28.4 billion including extensions; Barber Lake alone is listed at 300 MW over 20 years [4].

The evidence

The quarter's statement of operations shows the handover beginning [2].

Source: Cipher Digital, Exhibit 99.1, condensed consolidated statements of operations (unaudited) [2]. Dashes mean no revenue reported.

By Le Coin's calculation, leasing made up 21.9% of quarterly revenue. Mining revenue fell 70.9% from a year earlier and total revenue fell 62.8%. The cost of the leasing revenue was $726,000, leaving $5.1 million before overhead, also our arithmetic [2].

Cipher said the rent began "following rent commencement at Black Pearl," another of its campuses, and that it "delivered first capacity at Black Pearl with additional capacity across all three campuses expected to come online in phases over the coming months" [2]. It did not name the Black Pearl tenant in the release.

Beyond the sites under construction, Cipher says its "development pipeline today totals approximately 5.9 GW," or gigawatts, a measure of power capacity; one gigawatt is roughly what a large power plant produces [2]. That pipeline includes a "conditional base load classification for 1 GW at Colchis" and "conditional studied load classifications" for "an additional 1.6 GW" through the Texas grid operator ERCOT's "Batch Zero process," plus Horizon, "a 70 MW site in Texas expected to energize in 2029" [2]. The word conditional matters: none of that pipeline is described as built or energized.

The objection

The landlord business is expensive to build, and the balance sheet shows it. Long-term borrowings were $5.45 billion at Sept. 30, up from $2.71 billion at the end of 2025, and property and equipment rose to $3.90 billion from $633.4 million [2]. Interest expense was $59.0 million in the quarter, against $1.3 million a year earlier [2]. During the quarter Cipher "completed an $850 million offering of 0.000% convertible senior notes due 2032," bonds that can turn into shares, to fund more investment in Barber Lake [2]. It also said it "equitized approximately $165.9 million of the 1.750% convertible notes due 2030," swapping that debt for shares and "retiring more than 90% of those notes" [2]. A third campus, Stingray, is still a building site: Cipher says "shell construction" is "expected to be completed in the fourth quarter" [2].

The profit line can mislead. Cipher reported net income of $31.6 million for the quarter, but the same statement shows a $127.2 million gain from the "change in fair value of warrant liability," an accounting revaluation of rights to buy its shares, and an operating loss of $71.9 million [2]. The release puts adjusted EBITDA, which Cipher calls its primary non-GAAP performance measure, at "negative $10 million" [2]. Nine-month net loss was $350.2 million [2].

And the transition leaves the company with less bitcoin. Its bitcoin holdings were valued at $25.9 million at Sept. 30, down from $125.4 million at the end of 2025 [2].

The tell (Le Coin's view)

In Le Coin's view, the line to watch is HPC leasing revenue next quarter. Cipher says multiple data halls at Black Pearl and Barber Lake are "scheduled to come online through year-end" [2]. If that happens on schedule, more of Cipher's revenue will come from long contracts rather than from mining. If halls slip, the debt arrives before the rent does.

Stop

Cipher Digital earned its first rent from computing tenants in the third quarter: $5.9 million out of $26.7 million in revenue. Mining revenue fell to $20.8 million from $71.7 million. It says one site now carries about $9.1 billion of contracted rent and that its pipeline totals about 5.9 GW, much of it conditional and none of it described as energized.
