Cipher Compute 2 Phase I commencement
Company: Cipher Mining - Project: Barber Lake Facility
What the later record shows
The date slipped
The 9/30/2026 Phase I commencement was replaced by per-data-hall commencement, with the first in Q4 2026 and deliveries running into Q1 2027. No single new Phase I commencement date is named.
“Rent will commence for each data hall as it is delivered, with the first rent commencement expected to occur during the fourth quarter of 2026.”

How we checked this
Checked on October 12, 2026. The cited source supports part of this claim, but not all of it.
The document lists 9/30/2026 as an assumed Phase I Commencement Date in a financial model for 'Cipher Compute', not as a firm date for starting operations. It also does not name the facility 'Cipher Compute 2'.
Confirmed in the source:
- The presentation's key model assumptions list a Phase I Commencement Date of 9/30/2026 for Cipher Compute
We could not confirm this from the cited source:
- The facility is named 'Cipher Compute 2'; the document refers to 'Cipher Compute', and the '2' appears to be a page number
- Phase I will definitely commence on September 30, 2026; the document gives this date only as a model assumption and says actual amounts may vary with the construction timeline and other factors
- The 'Commencement Date' means the start of data center operations rather than, for example, a lease commencement date
That does not mean it is false — only that this source does not establish it, as of the date above. If we find a source that settles it, we will re-check and update this page.
What we did: Read our cached copy of SEC EDGAR (8-K Ex) (https://www.sec.gov/Archives/edgar/data/1819989/000095010325015073/dp237633_ex9902.htm) in full (12,658 characters, retrieved September 25, 2026) and checked each assertion in the claim against it.
