Strategy Inc bought no bitcoin between 31 August and 7 September, leaving holdings at 845,050 coins, and spent $176.3 million of cash buying back its own variable-rate preferred stock instead. An 8-K filed on 8 September said the company also sold no shares under its at-the-market program. The stack was acquired for $63.73 billion at an average $75,412 a coin, including fees. At this week's prices near $78,400 the bag is still above cost. It is not the $80,318 lot Strategy paid for 4,603 coins the week before, when Executive Chairman Michael Saylor posted "We're back." This filing is the other half of that capital structure: a bitcoin treasury that also has to service preferred dividends. The board doubled the Digital Credit Securities Repurchase Program from $1.0 billion to $2.0 billion. As of 7 September, $1.19 billion of that capacity remained. See how last week's 4,603-coin purchase was funded with ATM equity.
The only repurchase in the window was STRC, the Variable Rate Series A Perpetual Stretch Preferred Stock. Strategy bought 1,810,885 STRC shares for $176.3 million. STRF, STRK, STRD, and Class A common, ticker MSTR, were untouched. The $1.0 billion MSTR buyback authorization is still fully available. USD Cash fell to $1.44 billion from $1.61 billion on 30 August, matching the STRC spend. The USD Reserve, earmarked for preferred dividends and interest, stayed at $5.10 billion. That reserve is the reason the company can pause coin purchases without skipping a coupon. It is also why a week of zero bitcoin buying is not a liquidation. Metaplanet made the same point when it moved 4,800 BTC to Coinbase Prime. Custody and capital management are not sales. The market still has to believe the next 8-K.
A $2 billion preferred cap is a statement about the coupon, not the coin
Strategy raised STRC's annual dividend to 12% in June. Buying the paper back with cash reduces the future coupon load. Doubling the authorization says the board wants more of that option, not more ATM dilution this week. It also says bitcoin at $78,000 was not cheap enough, or not urgent enough, to compete with STRC trading below the level the company wanted on the books. Last week $369.7 million went to coins and $151.8 million went to STRC. This week the coins got nothing. That mix can flip again the moment the ATM is reopened. Until then, treat 845,050 as a round number that did not move, and $1.44 billion of USD Cash as dry powder that can buy either paper or bitcoin after Friday's CPI.
Corporate treasuries are not the ETF bid
U.S. spot Bitcoin ETFs took in $3.8 billion over three weeks while Strategy stood still. IBIT is a creation machine. Strategy is a leveraged equity with a preferred stack. One green ETF week does not force Saylor to print MSTR. One red STRC week does not force a bitcoin sale. The 8-K is the source, not a social post. For the tape, the tell remains whether IBIT keeps creating into the FOMC, not whether Tysons Corner writes another purchase line. For MSTR holders, the tell is whether USD Cash goes back into coins or into more STRC.
