Sphere 3D Plans 50 MW Kentucky Data Center as City Weighs Zoning Rules
Sphere 3D’s subsidiary North Campbell LandCo LLC plans a 50 MW data center in Hopkinsville, Kentucky, and to repurpose a 15 MW bitcoin mining site at the Hopkinsville Electric System’s Holland Substation for other computing uses, per a July 27 hearing report. North Campbell would fund an $8 million to $10 million substation. Zoning rules are under review; no approvals. Sphere reported $3.1M cash at March 31 and Q1 revenue of $1.9M. Shares closed at $2.35.
How this was made
The 30-second read
Why it matters
The city’s zoning amendment process and potential grandfathering for the existing 15 MW operation determine whether Sphere can expand compute capacity in Kentucky without substantial redesign or delays.
Market read
This is a concrete, location-specific expansion attempt tied to Sphere’s post-crypto compute strategy, but it remains contingent on zoning approval and further disclosures.
What to watch
The draft zoning rules could force design changes or setbacks, and the financing/cash burn context may limit how quickly Sphere can scale beyond the existing 53 MW operating base.
Background
Sphere 3D completed its acquisition of Cathedra Bitcoin on June 1, creating the North Campbell LandCo LLC subsidiary referenced in Hopkinsville’s public hearing.
Ticker impact
Sphere 3D’s subsidiary North Campbell is seeking zoning approval for a 50 MW Kentucky data center and a conversion of a 15 MW bitcoin site.
Near-term shares may trade on zoning/regulatory headlines and any follow-on disclosure of site, schedule, and customers; absent approvals, impact is likely incremental.
The article is a pre-approval public hearing with limited project specifics, but it ties directly to Sphere’s post-Cathedra expansion narrative and includes stated substation capex and potential grandfathering for the existing load.
Market effects
Highlights the permitting and power-supply bottlenecks for AI/HPC data center buildouts tied to crypto-to-compute transitions.
Could influence local utility planning and load flexibility programs in Hopkinsville, Kentucky.
Reinforces broader demand for grid capacity and regulatory clarity for power-intensive compute infrastructure.
Counterpoint
Because the proposals are not approved and key details (site, schedule, customers, total cost) are missing, the market may be overpricing the near-term probability of execution.
