Cipher Mining
Bitcoin miner turning power sites into AI data centers for AWS, Google, and others.
On the record
Checkpoint: Q2 2026 earnings, testing construction delivery and hunt for a fourth anchor tenant
The call
Cipher has the contracts and the power sites, but it's racing Hut 8, IREN, and TeraWulf to build fast enough before the debt and construction risk catch up.
Cipher Mining builds and operates large data centers that run artificial intelligence workloads for companies like AWS and Google, earning long-term contracts worth billions of dollars. The business is hard to copy because it requires land, cheap electricity, and fast connections to power grids, all of which take years to build, but at least eight competing companies with plenty of money are building the exact same thing right now in the same locations. The company owes about $5 billion and is still losing hundreds of millions each quarter, so if its construction projects do not finish on time and start making money by 2027, or if the shortage of available grid power suddenly eases, the company could run into serious trouble.
Why
01
AI pressure: None apparent. AI is Cipher's customer, not its predator: AWS, Fluidstack, and Google-backed leases feed the pivot, they don't threaten it. Could AI do the core job? Unlikely.
02
Bigger players: AWS, Google, Microsoft. Hyperscalers are Cipher's tenants today but could build their own power and land positions once grid queues ease, cutting Cipher out. Could a giant copy it? Yes, easily.
03
What protects it. Signed 10-15 year leases worth $11.4B plus scarce grid interconnection that takes years for anyone to replicate.
What would change this call
Barber Lake topping out and Black Pearl retrofit completion on stated 2026-2027 timeline. Shows whether Cipher can convert signed leases into cash flow without construction slippage.
Cipher signs (or fails to sign) a fourth anchor hyperscale tenant by Q2 2026 earnings. Indicates whether Cipher is still winning new capacity commitments against Hut 8 and IREN.
ERCOT interconnection approvals for pipeline sites like Reveille and Mikeska. Determines if Cipher's power position stays scarce or if peers gain equal access.

Key numbers
- $11.4B contracted revenue across three hyperscale leases
- $822M net loss in FY2025
- 907 MW live capacity, 3.3 GW in pipeline
Named risks
- High leverage across multiple debt tranches totaling billions against unproven cash flow.
- Construction delivery slippage at Barber Lake or Black Pearl could trigger lease penalties.
- Rival miners (Hut 8, IREN) signing competing mega-leases for scarce hyperscaler tenants.
- ERCOT interconnection scarcity easing could erode Cipher's time-limited power advantage.
- Only 66 employees managing multi-gigawatt builds and $11.4B in contracts.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Hut 8 | contesting | Signed $9.8B, 15-year AI lease (Beacon Point) on 2026-07-20 |
| IREN | contesting | Disclosed $2.8B in new AI cloud contracts on 2026-07-20 |
| TeraWulf | contesting | Struck comparable $3.7B Google-backed Fluidstack deal in 2025-08 |
| AWS, Google, Microsoft (hyperscalers) | gaining on | Currently Cipher's tenants but power/time-constrained from insourcing as of 2026 |
Questions people ask
- Is Cipher Mining profitable in 2026?
- No. Cipher Mining (now Cipher Digital) posted a $114 million net loss in Q1 2026 on revenue of $34.84 million, an improvement from a $734 million loss in Q4 2025, but the company remains unprofitable as it builds out AI data centers, per its May 5, 2026 earnings transcript.
- Is Cipher Mining still mining Bitcoin?
- Largely no. Cipher sold its 49% JV stakes in the Alborz, Bear, and Chief mining sites and fully decommissioned Black Pearl from mining in February 2026, renaming itself Cipher Digital Inc. as it pivots almost entirely to leasing AI/HPC data center capacity.
- Who is Cipher Mining's biggest competitor?
- Ex-Bitcoin miners turned AI landlords: Hut 8 signed a $9.8 billion, 15-year AI lease and IREN disclosed $2.8 billion in new AI cloud contracts, both on July 20, 2026, the same day as competing news on Cipher, showing direct rivalry for hyperscaler tenants.
- Could AI replace Cipher Mining?
- No, AI is Cipher's tailwind, not a threat. Cipher is a physical infrastructure landlord leasing power and land to AI companies like AWS and Google-backed Fluidstack; its $11.4 billion in contracted revenue (as of May 5, 2026) depends on AI demand growing, not on AI replacing its function.
- Who owns Cipher Mining and does Google have a stake?
- Cipher Mining trades publicly as CIFR with no single parent; institutional ownership was about 12.26% and insiders about 2.63% as of July 21, 2026. Google received warrants for roughly 5.4% pro-forma equity as part of its September 25, 2025 Fluidstack lease backstop.
- How much debt does Cipher Mining have?
- Cipher Digital carries multiple large debt tranches: a $2.0 billion senior secured bond at 6.125% (due 2031), $1.7 billion at 7.125% (due 2030), $1.3 billion in 0% convertibles (due 2031), and $173 million in 1.75% convertibles (due 2030), disclosed as of March 31, 2026.
