The funds for this increase in BTC holdings were obtained by selling stocks, specifically the sale of MSTR shares worth $519.5 million last week.

According to BlockBeats news on June 30, reported by The Block, Strategy (formerly MicroStrategy) has increased its holdings by 4,980 Bitcoins (totaling $531.9 million) funded by the proceeds from the sale of its Class A common stock MSTR, convertible preferred stock STRK, and permanent Strife preferred stock STRF through ATM (at-the-market) offerings. Last week, Strategy sold 1,354,500 shares of MSTR stock for approximately $519.5 million. The company stated that as of June 29, there is still $18.1 billion worth of MSTR stock available for issuance and sale under this plan. Strategy also sold 276,071 shares of STRK stock for about $28.9 million, with $20.5 billion worth of STRK stock still available for issuance and sale under this plan. Meanwhile, the company sold 284,225 shares of STRF stock for $29.7 million, leaving a remaining quota of $1.9 billion under this plan. Strategy's STRK and STRF perpetual preferred stocks have ATM issuance plans worth $21 billion and $2.1 billion respectively, which are supplemental to the company's "42/42" plan. The "42/42" plan aims to raise $84 billion through equity issuance and convertible notes for Bitcoin acquisitions (originally a $42 billion plan, expanded after the equity portion was exhausted), with a target completion deadline of 2027.
