STRC is Strategy Inc’s (NASDAQ: MSTR) Variable Rate Series A Perpetual Stretch Preferred Stock, trading on the Nasdaq Global Select Market. Each share has a $100 stated amount and pays a cumulative monthly cash dividend at a variable annual rate set by the board (currently 11.50% as of March 2026). The rate cannot be cut by more than 25 bps per month and can never fall below one-month SOFR. When STRC trades above its $100 par value, Strategy can issue new shares through an ATM program and use the net proceeds to acquire Bitcoin.

This is an independent, unofficial dashboard that estimates STRC ATM (At-The-Market) activity in real time. It tracks the volume of STRC shares traded above the $100 par value threshold — which is when the ATM program is eligible to issue new shares and use proceeds to purchase Bitcoin.

We use publicly available market data to estimate ATM proceeds. When STRC trades above $100, a portion of that volume is assumed to be ATM issuance. The "Capture Rate" slider (default 42%) lets you adjust what percentage of above-threshold volume you believe represents ATM activity. Estimated proceeds are then divided by the current BTC price to derive an equivalent Bitcoin figure.

The Capture Rate is a user-adjustable assumption for what percentage of STRC trading volume above $100 represents actual ATM share issuance. The default of 42% is a rough historical estimate. You can adjust the slider to model different scenarios. This directly affects all downstream estimates (proceeds, BTC acquired, supply %).

Market data refreshes approximately every 60 seconds during market hours. STRC price and volume data is sourced from Polygon.io (with a ~15-minute delay on the Starter tier). BTC price comes from CoinGecko. SEC filing data is based on confirmed 8-K filings and updates when new filings are published.

After the April 2024 halving, approximately 450 BTC are mined per day globally. This metric shows how the estimated BTC acquired through STRC ATM activity compares to that daily mining output. A value of 300% means the estimated daily acquisition is 3x the amount of new Bitcoin mined that day.

The heatmap includes pre-market (4:00 AM – 9:30 AM ET) and after-hours (4:00 PM – 8:00 PM ET) trading sessions, shown at reduced opacity. Extended hours volume is included in the daily totals because ATM issuance can occur during these sessions.

Confirmed BTC figures are sourced directly from Strategy's SEC 8-K filings, which disclose actual shares sold, net proceeds, and Bitcoin purchased during each reporting period. These are not estimates — they are official, audited disclosures.
