Strategy (MSTR) Stock Soars 32% Over Three Days as Bitcoin Surges Past $70K

Strategy (MSTR) shares jumped more than 32% over three days as Bitcoin surged past $70,000 for the first time since June 2026. The rally lifted MSTR by over 10% in Friday’s pre-market on Aug. 21, rising from Thursday’s close of $112.39 to $124.60, and adding strength even as Bitcoin climbed roughly 8% in a 24-hour period. The move was linked to U.S. Treasury plans to expand bond buyback programs and a White House digital-asset summit featuring President Trump. Bitcoin’s jump triggered about $1.44 billion in short liquidations across crypto venues. Strategy holds 840,447 BTC bought for $63.36 billion, now valued near $65.04 billion.
