Strategy, the largest corporate Bitcoin holder, recorded an estimated $20.91 billion mark-to-market gain on its digital-asset holdings for the third quarter, against $1.88 billion of associated deferred tax expense. The figure reflects fair-value accounting on a position that the company grew last week to a record 848,000 BTC.

"Strategy reports a $21 billion gain on digital assets in Q3 2026. Last week, we acquired 334 $BTC and repurchased $176M of $STRC. As of 10/4/26, we hold 848,000 BTC and $5.7B of USD Assets," the company posted on X on October 5.

Between October 1 and 4, Strategy acquired 334 BTC at an aggregate $28.7 million, an average of $85,838.80 a coin. It bought nothing in the final three days of September.

Where did the larger capital allocation go?

Strategy spent more than six times as much buying back its own preferred stock as it did adding Bitcoin. The company retired 1,033,168 Stretch (STRC) shares for $102.6 million in the last days of September and a further 740,634 shares for $73.7 million in the first four days of October, $176.3 million in total.

Funding for the buyback split between $154.1 million from the USD Cash balance and $22.2 million from interest earned on cash and short-term investments. The Stretch repurchase program retains $547.2 million of authorized capacity.

STRC has traded below its $100 par value for months. The buybacks let Strategy retire preferred at a discount while deferring larger spot Bitcoin purchases that would execute above its own $75,440.70 average basis.

How is Strategy funding its activity?

The company sold 92,894 MSTR common shares for $15.7 million in net proceeds across the same windows, all of which went into Bitcoin. An additional $13 million drawn from USD Cash funded the same purchase. None of Strategy's four preferred series were sold through at-the-market programs in either window.

Dollar holdings now split across two buckets:

• USD Reserve of $4.88 billion covering preferred dividends and debt interest
• USD Cash of $833.4 million for general purposes, including Bitcoin purchases

In the week to October 4 the company drew $142.5 million from the reserve to service dividends and interest.

Why is the preferred buyback larger than the Bitcoin add?

The 334 coins bought last week cost nearly 14% more than Strategy's $75,440.70 average across the full position. The company is adding Bitcoin above its own basis in small increments while directing larger sums at a preferred stock that has priced below par.

Is the pattern limited to Strategy?

Strategy is not alone. Fellow Bitcoin treasury firm Metaplanet sold 10,000 BTC and bought back 11,000 during its own third quarter, a round trip the Japanese company staged to show credit rating agencies it could turn Bitcoin into cash on demand. Both companies now spend as much attention on the credit side of the balance sheet as on accumulation.

The contrast between the modest Bitcoin add and the larger preferred buyback will frame the next disclosure cycle. Strategy's STRC authorization continues until further board action, and any sustained recovery of the stock above $100 par would let the company reallocate the remaining $547.2 million back to spot Bitcoin.
