How we checked this
Checked on October 15, 2026. The cited source supports part of this claim, but not all of it.
The release mentions both 15 J/TH efficiency and a recent fleet refresh, but in separate points; it does not say the efficiency figure follows from the refresh.
Confirmed in the source:
- IREN cites 15 J/TH efficiency as a driver of its low-cost Bitcoin production
- IREN has completed a recent mining fleet refresh
We could not confirm this from the cited source:
- IREN's 15 J/TH efficiency is a result of the recent fleet refresh
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/1878848/000187884825000047/a50ehsupdate_vff.htm) in full (18,640 characters, retrieved October 11, 2026) and checked each assertion in the claim against it.
