CIFR Stock Data Center Analysis
Cipher's complete named site portfolio, including Apollo, initial Black Pearl rent, contracted campuses and the remaining grid and generation pipeline.
In this article
Cipher Digital's data center portfolio now spans operating Bitcoin infrastructure, three contracted HPC campuses and a much larger development pipeline. The important change is that the first contracted HPC capacity has started earning rent. The important remaining distinction is that most of the advertised megawatts are still future projects.
This guide covers all eleven named sites in Cipher's August 2026 portfolio, including Apollo, plus the three former joint-venture sites. Use the Cipher Data Center Tracker to compare locations, evidence dates and development stages alongside this overview.
The complete named portfolio
The following inventory follows Cipher's August 4 portfolio presentation. Capacity is gross electrical capacity. Future dates are management targets, and the Texas pipeline remains subject to the applicable grid process.
Site | Gross capacity | Reported stage or target |
|---|---|---|
300 MW | First HPC capacity delivered; later phases under construction | |
300 MW | Tenant beneficial use; initial delivery targeted September 2026 | |
Stingray | 100 MW | Contracted; delivery targeted H1 2027 |
Odessa | 207 MW | Bitcoin mining; HPC discussions |
Reveille | 70 MW | Substation development; Q3 2027 target |
Ulysses, Ohio | 200 MW | Substation development; Q4 2027 target |
Colchis | 1,000 MW | Grid development; 2028 target |
Mikeska | 500 MW | Grid development; 2028 target |
McLennan | 500 MW | Grid development; 2028 target |
Milsing | 500 MW | Grid development; 2030+ target |
Apollo | Up to 900 MW | Site option; 2030+ target |
The same presentation identifies potential additions at Barber Lake and Stingray. These are expansions of existing locations, so counting them as separate campuses would overstate the site count. The inventory deliberately keeps one row per named site.
What has changed at the contracted sites
Cipher's second-quarter update reported initial Black Pearl delivery in August and commencement of rent. That supersedes the older October start expectation for the first capacity. It does not establish delivery of the whole campus.
Stingray is now an identified, financed project. The same update reported completion of its $810 million financing, intended to fund development through substantial completion. Treating the site as a guess about an unnamed third lease is obsolete.
The three projects still need to be followed separately. A tenant's early access, partial occupancy, rack installation and rent commencement can occur at different milestones. Combining them into one company-wide label such as "operational" hides the most useful information.
September's generation development
On September 3, Cipher announced lateral gas-pipeline development intended to support up to 2.5 GW of on-site electricity generation across multiple locations, with new power targeted before the end of 2027. Power providers would develop and operate the generation infrastructure.
That is a development programme, not an announcement that 2.5 GW is already energized. It also cannot simply be added to every grid-connected site. An allocation needs evidence identifying the location, generation capacity and overlap with existing plans.
There is a disclosure reconciliation still to resolve: the August deck describes roughly 4.4 GW of grid pipeline, while the September release's company description uses roughly 3.4 GW. This guide retains the dated site inventory rather than silently choosing a new aggregate. A revised site schedule would be stronger evidence than interpreting a shorter corporate description as a cancellation notice.
Former sites and ownership
Cipher's June-quarter filing records the February 19 sale of its 49% interests in Alborz, Bear and Chief Mountain. Those names belong in the company's history, not in today's owned development inventory.
Ownership matters throughout the portfolio. A site option is different from a completed purchase, and control of a development is different from ownership of the tenant's GPUs. Cipher's operating model centres on delivering the physical campus and its contracted services.
How to read the next update
The useful sequence is site control, usable power, construction, tenant acceptance and revenue. A lease reduces demand uncertainty, but leaves delivery and financing obligations. A financing announcement improves the funding position, but does not make the customer ready to pay.
The site studies above explain those dependencies at Black Pearl and Barber Lake. For the broader business model and research archive, see Cipher Digital coverage.
