At-the-market equity programs
MSTR common ATM has $18.83B capacity left as of Oct 4, 2026; STRC program has $17.51B.
The numbers
What it is
The company sells common and preferred stock to the market on a continuing basis, through separate ATM programs for MSTR common, STRC, STRD, STRK and STRF. Proceeds fund bitcoin purchases and the USD Reserve. Remaining capacity is reported in each 8-K.
Why it matters to the stock. The ATM capacity is the company's funding pipe for new bitcoin. The remaining capacity, and whether the common ATM is used at all, shows how the market is pricing MSTR against its bitcoin holdings.
