Sphere 3D agrees to sell its legacy miners to fund an AI infrastructure shift
Source report: 2026-09-08 · Editorial analysis published: 2026-09-13
The September 8 review separates legacy equipment sales, revenue-share mining and proposed Kentucky development. Financing and project targets remain subject to completion and approvals.
Analysis and practical implications
This section is our analysis and illustrative calculations, separate from the source report.
A strategic review with several separate transactions
Sphere 3D, operating as DarkHorse Technologies, disclosed the outcome of a 90-day strategic review on September 8, 2026. Its plan combines selling non-core mining assets with raising capital and developing AI and high-performance computing infrastructure. The announcement is a set of agreements and proposals, not proof that every transaction has closed or that an AI campus is operating. ASIC.tools retains the original announcement date. In particular, an expected closing date does not become a confirmed closing simply because that date has passed. The distinction matters here because the company is changing the mix of assets it owns while retaining a form of Bitcoin mining exposure.
What is being sold
The company agreed to sell its Iowa site for US$1.5 million and expects roughly US$500,000 from utility deposits and related prepayments. It also agreed to sell approximately 5,500 legacy mining machines for around US$3 million. These are different sources of expected proceeds. Recovering a deposit is not the same as receiving a higher purchase price for the land or equipment. The release does not provide enough model-level information to derive a reliable market price for an individual ASIC. Dividing aggregate proceeds by the machine count would ignore fleet condition, model mix and transaction terms. We therefore do not insert such a quotient into the equipment catalogue as a retail quotation.
Mining continues through another structure
Bitdeer supplies and owns hardware at 20 MW out of the 30 MW covered by joint mining agreements, according to the release. The third site was expected online before November 2026. Sphere describes its mining exposure primarily as hosting with a share of revenue: it controls sites and power while another party owns the specified machines. Selling a legacy fleet therefore does not mean that all mining activity disappears. Operators comparing businesses should distinguish owned hashrate from electrical hosting capacity and from a contractual revenue share. The release also says termination provisions preserve the ability to reallocate capacity to AI/HPC; that flexibility is not itself a completed conversion or an AI customer contract.
A new project and an existing site are distinct
A subsidiary secured an option on approximately 20 acres in Hopkinsville, Kentucky. The proposed development would draw about 50 MW and use a new 65 MW substation, with the remaining 15 MW available to other utility customers. Sphere offered to fund the substation at an estimated US$8 million to US$10 million. Required zoning and other approvals were not all in place. Separately, the company is assessing conversion of an existing Hopkinsville operation contracted for roughly 15 MW. Readers should not merge that existing operation with the proposed new campus or treat the difference between substation capacity and data-center load as an already realized efficiency measure.
Financing is not operating revenue
The planned private placement targets approximately US$5 million in gross proceeds and was expected to close around September 11, subject to conditions. The announcement describes 1,666,661 units at US$3 each, with a share and a five-year warrant exercisable at US$3.50. Capital raised is not revenue earned from AI customers, and gross proceeds are not a construction budget net of all expenses. Potential future warrant exercise is another separate event. For a project assessment, the amount and timing of money actually received should be checked against spending commitments rather than simply added to possible asset-sale proceeds and presented as available cash. We have not independently confirmed the closing in this article.
What should be checked next
The next meaningful milestones are completed disposals and financing, regulatory approvals, construction, commissioned capacity and signed customer commitments. The release describes intended use of proceeds, not guaranteed AI utilization or profit. After the Iowa sale the company expects about 50 MW of energized capacity across four Tennessee and Kentucky sites, excluding the proposed new campus; that portfolio number should remain separate from the new project's similarly sized target. For miners, the case illustrates how ownership of equipment and control of power can move in different directions. The primary announcement is linked below.
