How we checked this
Checked on September 21, 2026. The cited source supports part of this claim, but not all of it.
The document confirms a $2.0Bn high-yield bond at 6.125% maturing February 2031, but describes it only as a high-yield/non-recourse bond, not explicitly as 'senior secured'.
Confirmed in the source:
- Cipher issued a $2.0 billion high-yield bond at a 6.125% coupon
- The bond has a February 2031 maturity
We could not confirm this from the cited source:
- The $2.0 billion Black Pearl notes are 'senior secured'
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/1819989/000181998926000007/cipherdigital_businessup.htm) in full (25,132 characters, retrieved September 13, 2026) and checked each assertion in the claim against it.
