PRISM REASONING
  • Fundamental analysis indicates a very high likelihood that Strategy Inc eventually sells at least a token amount of Bitcoin by the deadline
  • Over a long horizon, corporate liquidity, risk management, or structural events often override stated 'never sell' policies
FACTORS FOR
  • +Multi‑year horizon makes any non‑zero sale path-likely
  • +Large BTC position versus business scale increases balance‑sheet management pressure
FACTORS AGAINST
  • Management’s articulated and repeated 'never sell' strategic stance
  • Strong brand and equity story tied to uncompromising BTC accumulation
RESOLUTION PATHS MODELED
Small BTC sale driven by liquidity, margin, or risk constraints55%
BTC sale tied to M&A, restructuring, or governance/leadership change31%
Evidence 52%
