Strategy Inc. heads into the final trading week of 2025 with U.S. stock markets shut for the weekend, leaving investors to handicap Monday’s open using two main inputs: Bitcoin’s weekend tape and year-end equity positioning. Shares of Strategy last closed at $158.81 on Friday, Dec. 26, before slipping in after-hours trading to $158.14. Meanwhile, Bitcoin changed hands around $87,881 Sunday morning, a level that matters disproportionately for Strategy because its equity often trades like a high-beta proxy for BTC—sometimes magnifying both rallies and drawdowns.
