MicroStrategy, led by Michael Saylor, reported an unrealized $17.44 billion loss in Q4 2025 due to declining Bitcoin prices, with shares dropping nearly 70% from their 2024 peak. In December, the company sold stock to raise cash, reflecting reduced investor confidence. Despite setbacks, MicroStrategy remains heavily invested in Bitcoin, holding 672,497 BTC valued at about $50.44 billion as of late December 2025.
