Strategy (MSTR), the largest publicly traded bitcoin holder sold a record amount of its perpetual preferred stock, Stretch (STRC), on Monday, using the proceeds to buy about 1,420 bitcoins, according to data from STRC.live.
Earnings from STRC, which debuted in July 2025, support the company’s bitcoin accumulation strategy. Monday’s session saw nearly $300 million in total trading volume, compared to a 30-day average of $124 million, according to the company’s dashboard.
The estimates are based on a methodology that infers purchases from sales in the market (ATM). The approach assumes that 40% of trading volume above $100 represents ATM issuance, with a 2.5% broker fee deducted before calculating the implicit purchase of bitcoins.
Last week, Strategy bought approximately $1.3 billion worth of BTC, almost 18,000 coins.
Strategy has described the STRC as something akin to a short-duration, high-yield savings instrument. The company recently raised STRC’s dividend rate to 11.5%. The stock pays monthly cash distributions. The dividend rate is adjusted each month to keep the stock trading close to its par value of $100 while limiting price volatility.
In an 8K filing on Monday, Strategy amended its Omnibus Sales Agreement to allow multiple dealers to sell the same class of securities on a single trading day during pre-market or after-hours sessions. The change allows additional agents to handle early or late transactions, while bulk sales after 4 p.m. ET remain permitted.
Strategy shares are up about 3% in premarket trading, to around $143 per share.
