Strategy Bitcoin Treasury Tracker

Strategy (formerly MicroStrategy) holds 848,000 BTC as of October 5, 2026 — the largest corporate Bitcoin treasury in the world. This tracker follows that stack and the weekly buying that grows it, every total reconciled against Strategy's SEC 8-K filings.

What this tracker shows

The live dashboard surfaces Strategy's current Bitcoin holdings, each week's confirmed purchases (and any sales), and the daily accumulation estimated between filings. Confirmed rows are marked SEC VERIFIED; estimates are model-derived and replaced the moment the 8-K lands. See the methodology for exactly how daily estimates are built.

How Strategy funds the treasury

Most of the recent buying is funded by STRC (Stretch Preferred), a variable-rate preferred stock Strategy sells through an at-the-market offering. Learn what STRC is and how it works, or jump to the dedicated Strategy Bitcoin holdings page.

Why reconcile to filings?

Treasury trackers that rely on announcements or round numbers drift from reality. Every confirmed figure here is parsed directly from Strategy's SEC 8-K filings on EDGAR — the primary source — so the stack you see matches what the company actually reported.
