CB-2 delivery timeline

What the later record shows
Delivered late · happened March 31, 2026
Only 18 MW (WULF Den + CB-1) was online at 2025 year-end, so CB-2 missed Q4 2025. CB-2A was online by February 2026 (39 MW) and CB-2B was listed as delivered as of March 31, 2026.

How we checked this
Checked on October 10, 2026. The cited source supports part of this claim, but not all of it.
The document says CB-2 is on track for Q4 delivery but does not name the year. The August 2025 date of the presentation suggests 2025, but the document never states it.
Confirmed in the source:
- CB-2 is on track for Q4 delivery
We could not confirm this from the cited source:
- That the Q4 delivery target for CB-2 is specifically Q4 2025 (the document does not state the year)
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 IR page (investors.terawulf.com) (https://d1io3yog0oux5.cloudfront.net/_0c87b48cb4d1c6967968c7d0c3e5933d/terawulf/db/2396/23304/pdf/WULF_Expands_Fluidstack_Deal_August_2025.pdf) in full (11,936 characters, retrieved September 1, 2026) and checked each assertion in the claim against it.
