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 21-month window and the October 22, 2020 IPO closing, which together put the deadline at July 22, 2022. However, the deadline belongs to Good Works Acquisition Corp., not to Cipher Mining as the claim states.
Confirmed in the source:
- Good Works Acquisition Corp. has 21 months from the closing of its Public Offering to complete a Business Combination (the 'Combination Period')
- Good Works' Public Offering closed on October 22, 2020
- 21 months from October 22, 2020 is July 22, 2022, though the filing never states that date
We could not confirm this from the cited source:
- That the 21-month deadline is an obligation of Cipher Mining; the filing places it on Good Works Acquisition Corp. (the SPAC), with Cipher Mining Technologies as its merger target
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/1819989/000121390021041397/f10q0621_goodworks.htm) in full (117,489 characters, retrieved September 13, 2026) and checked each assertion in the claim against it.
