How we checked this
Checked on October 11, 2026. The cited source supports part of this claim, but not all of it.
The filing confirms the batch size, supplier and facility, but it presents the August 2022 operational date as something the company anticipated, not a certainty. The claim states it as a definite outcome.
Confirmed in the source:
- TeraWulf's initial batch was 3,000 S19 XP mining machines
- The machines came from previously announced purchase agreements with Bitmain Technologies Limited
- The machines were for TeraWulf's Lake Mariner facility in New York
- As of July 1, 2022, TeraWulf said it anticipated the initial batch would be operational in August 2022
We could not confirm this from the cited source:
- That the initial batch of 3,000 S19 XP machines definitely would be, or actually became, operational in August 2022 (the filing states only the company's expectation)
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 (https://www.sec.gov/Archives/edgar/data/1083301/000110465922076754/tm2220243d1_8k.htm) in full (7,344 characters, retrieved September 13, 2026) and checked each assertion in the claim against it.
