Sphere 3D: power sites, Bitdeer mining and a proposed AI infrastructure shift
Sphere 3D’s 2026 story is about power sites before it is about artificial intelligence. The company has combined its Bitcoin-mining background with Cathedra Bitcoin’s data-centre footprint, then begun evaluating whether those electricity-connected facilities could support high-performance computing and AI workloads as well as mining.
That is an important distinction. A powered site is not yet an AI data centre with contracted customers. It can be a starting point: a location with utility relationships, operating equipment and a history of running compute loads. Sphere 3D’s own 2026 investor material describes the next stage as a combination of co-mining, site conversion planning, potential new construction and a proposed DarkHorse Technologies rebrand.
The Cathedra combination changed the starting point
Sphere 3D completed its business combination with Cathedra Bitcoin on 1 June 2026. Cathedra became a wholly owned subsidiary of Sphere 3D in an all-share transaction. The company said the combined platform had approximately 53 megawatts of operating power capacity across several US data-centre locations, with a development pipeline of more than 100 MW of potential expansion opportunities.
Those two numbers describe different things. Operating capacity is power that the company said was already available across its sites. A development pipeline is a set of potential additions that still requires work, approvals, capital or commercial execution. Treating the pipeline as completed capacity would overstate what the combined company had in service.
Cathedra brought a different emphasis to Sphere 3D’s earlier mining operation. Sphere 3D had been focused on industrial-scale Bitcoin mining and equipment. Cathedra had developed and operated power infrastructure for high-density computing. The combination was intended to put the resulting sites, power relationships and public-company platform behind a broader digital-infrastructure strategy.
The 30 MW Bitdeer agreements keep power in use
On 25 June 2026, Sphere 3D announced co-mining agreements with Bitdeer Technologies covering 30 MW across three data-centre sites in Tennessee and Kentucky. The arrangement was designed to use existing power capacity for mining while Sphere 3D continued to evaluate AI and high-performance-computing applications for the sites.
The company described the agreements as flexible and said they had an initial one-year term, with a possible further one-year renewal. Bitdeer was to provide the mining equipment, while the parties would share net mining proceeds. The structure is significant because it does not turn the locations into AI facilities; it gives them an operating use while the company considers a different future mix of computing workloads.
Sphere 3D’s second-quarter 2026 update said it had installed the first of the three sites and expected the remaining two to be fully installed before November. The update also made clear that the co-mining arrangements were part of an evaluation period. Installed mining equipment, contracted co-mining capacity and a future AI deployment are separate stages of the company’s plan.
Why a smaller power site can still matter
Sphere 3D has described a strategy based on “power-ready” infrastructure: smaller sites where power is available and new computing equipment can be deployed in modular form. The company’s investor presentation refers to retrofitting existing mining locations, using prefabricated data-hall components and focusing on 10 MW to 50 MW facilities rather than trying to build a hyperscale campus from scratch.
The company’s argument is that an energised site has practical value because it already has a power connection, utility relationship and operating history. That can reduce one of the biggest constraints in data-centre development: waiting for a new grid connection. It does not remove the need to design the facility, obtain any required approvals, finance the equipment or secure customers.
Hopkinsville remains a development plan
In its August 2026 business update, Sphere 3D said it was planning the potential conversion of an existing approximately 15 MW facility in Hopkinsville, Kentucky, and evaluating a new 50 MW data centre. The company also proposed funding a 65 MW substation that it said could make capacity available to other local utility customers.
These are development steps, not a declaration that a new facility has opened. The company’s materials identify further conditions around the project, including utility, zoning, regulatory and construction matters. The same caution applies to any potential use for AI or high-performance computing: Sphere 3D said it was still discussing opportunities with prospective offtakers, co-tenants and other commercial counterparties.
The proposed DarkHorse identity
Sphere 3D’s board approved and recommended a proposed change of name to DarkHorse Technologies Inc. in June 2026, with the DRK ticker reserved for use once the relevant steps became effective. The company’s own subsequent investor presentation continued to describe the business as Sphere 3D Corp. doing business as DarkHorse Technologies, and said the legal name and ticker changes remained subject to further procedures and conditions.
This is why the rebrand should be described carefully. The DarkHorse name captures the intended move toward power-first digital infrastructure, but a proposed or trading identity is not the same thing as a completed legal name change. The underlying assets and commercial plans matter more than the label attached to them.
The financial position frames the execution challenge
For the quarter ended 30 June 2026, Sphere 3D reported approximately US$2.5 million in revenue, a net loss of US$13.8 million and US$2.8 million in cash and cash equivalents. Cathedra’s results were included from 1 June, rather than for the whole quarter. The company also reported bitcoin holdings valued at about US$1.2 million at quarter end.
Those figures put the strategy in context. Developing or converting a data-centre site requires more than a land option or a power agreement. It requires capital, equipment, operations and customers willing to use the capacity. Sphere 3D’s own disclosures show a company that has acquired a power footprint and is testing how to monetise it, rather than one that has already completed a large AI-infrastructure rollout.
For now, the company’s known operating base is the combination of its mining activity, Cathedra’s sites and the Bitdeer agreements. The potential AI and high-performance-computing business is the next phase being developed around that base. Progress will depend on the company converting its power-ready locations into contracted, operating computing capacity.
