CB-2 HPC Deployment Q4 2025
Company: TeraWulf - Project: Lake Mariner Anthropic AI Factory
What the later record shows
The date slipped · new target December 31, 2026
Only 18 critical IT MW were energized at year-end 2025, so the 50 MW CB-2 was not online in Q4 2025. Capacity reached 39 MW by February 2026, and the company acknowledged building timing impacts.

How we checked this
Checked on October 10, 2026. The cited source supports part of this claim, but not all of it.
The document targets CB-2 for Q4 2025 at 50 MW, but labels that figure as gross capacity. It lists the critical IT capacity as 40 MW.
Confirmed in the source:
- TeraWulf targeted Q4 2025 for the 50 MW CB-2 HPC deployment
- The 50 MW figure appears on the HPC hosting timeline
We could not confirm this from the cited source:
- The 50 MW for CB-2 is critical IT capacity (the document labels the timeline figures as gross load capacity and lists CB-2 at 40 MW critical IT)
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/2396/23301/pdf/WULF_Q1_2025_Investor_Pres_vF.pdf) in full (23,307 characters, retrieved September 1, 2026) and checked each assertion in the claim against it.
