Strategy (MSTR), the largest publicly traded holder of bitcoin BTC$70,747.45, sold a record number of its perpetual preferred equity, Stretch (STRC), on Monday, using the proceeds to purchase about 1,420 bitcoin, according to data from STRC.live.

Proceeds from STRC, which debuted in July 2025, support the company’s bitcoin accumulation strategy. Monday’s session recorded nearly $300 million in total trading volume, compared with a 30-day average of $124 million, according to the company’s dashboard.

The estimates are based on a methodology that infers purchases from at-the-market (ATM) sales. The approach assumes 40% of trading volume above $100 represents ATM issuance, with a 2.5% broker commission deducted before calculating the implied bitcoin purchase.

Last week, Strategy bought roughly $1.3 billion worth of BTC, nearly 18,000 coins.

Strategy has described STRC as resembling a short-duration, high-yield savings instrument. The company recently raised the dividend rate on STRC to 11.5%. The stock pays monthly cash distributions. The dividend rate is adjusted each month to keep shares trading close to their $100 par value while limiting price volatility.

In an 8 K filing Monday, Strategy amended its Omnibus Sales Agreement to allow multiple agents to sell the same class of securities on a single trading day during pre-market or after-hours sessions. The change enables additional agents to handle early or late trades, while block sales after 4 p.m. ET remain permitted.
Strategy shares are up about 3% in pre-market trading to around $143 per share.
