Strategy Inc. shares closed September 4, 2026, at $142.80, up about 12% from the prior Friday’s $127.31 close. The move followed a volatile week that included a 17.56% Thursday jump to $144.82 and a 1.39% Friday pullback, as Bitcoin retreated from its midweek high. The rally coincided with Bitcoin reclaiming $80,000, Strategy’s first sizable Bitcoin purchase in roughly 10 weeks and a major increase in its weighting in Fundstrat’s Granny Shots U.S. Large Cap ETF, ticker GRNY. Strategy bought 4,603 Bitcoin for about $369.7 million, averaging $80,318 per coin, lifting its holdings to 845,050 Bitcoin acquired for $63.73 billion, or approximately $75,412 each. The company sold 4,531,421 Class A shares for $602.8 million to fund the activity, with proceeds also supporting an approximately $152 million repurchase of STRC preferred stock, preferred dividends and an increase in dollar cash to about $1.61 billion at the end of August. B. Riley raised its price target to $175 while retaining a Buy rating, and Alliance Global Partners upgraded the stock to Strong Buy. Strategy remains well below its 52-week high of $365.21 and is widely viewed as a high-beta proxy for Bitcoin, meaning a stock that tends to amplify the asset’s moves. GRNY made Strategy its largest position at about 2.7% to 2.8% of assets, or 947,206 shares, after moving it from near the bottom of the portfolio to the top in about two weeks. Bloomberg ETF analyst Eric Balchunas highlighted the shift, while noting Fundstrat chairman Tom Lee’s connection to BitMine, an ether-treasury company. Strategy and Google Cloud also announced an October AI Transformation Forum series, and the company expanded a government-data partnership with Carahsoft. The week’s gains reflected several overlapping factors rather than one headline, and their durability will depend on Bitcoin’s performance, treasury activity, ETF positioning and interest-rate commentary.
