How we checked this
Checked on October 15, 2026. The cited source supports part of this claim, but not all of it.
The document confirms Core42's 72.5 MW gross lease at Lake Mariner and schedules it for 2025, but it only says the capacity was planned for 2025, not that it was delivered.
Confirmed in the source:
- Core42 leases 72.5 MW at Lake Mariner
- The 72.5 MW is gross contracted HPC hosting capacity
- The capacity overview lists Core42's 72.5 MW for 2025
We could not confirm this from the cited source:
- That the full 72.5 MW was actually delivered in 2025 (the August 2025 document shows only planned 2025 deployment, with CB-2 still pending Q4 delivery)
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/_513c80c486e62e4bdb70115ded3782f5/terawulf/db/2396/23302/pdf/WULF_Q2_2025_Investor_Update_%28Aug_2025%29vF.pdf) in full (17,599 characters, retrieved October 13, 2026) and checked each assertion in the claim against it.
