MicroStrategy Bitcoin Holdings: How Much BTC Strategy Owns and Why It Drives MSTR

Strategy’s software business has brought in between $111 million and $129 million of revenue every quarter since early 2025. Over the same stretch its net result has swung from a $12.5 billion loss to a $10 billion profit. The difference is bitcoin. Strategy, the company formerly called MicroStrategy, held 848,517 BTC as of October 18, 2026, bought for $64.02 billion at an average of $75,446 per coin. That is about 4% of the 21 million bitcoin that will ever exist.

So the MicroStrategy bitcoin position is not a side bet on the balance sheet. At the end of June, digital assets made up $49.67 billion of Strategy’s $52.56 billion in total assets. The coins are the balance sheet, and they decide both the earnings and the share price.

Strategy’s bitcoin holdings in numbers

Strategy reports its holdings every Monday in a Form 8-K filed with the SEC. The figures below come from the October 19, 2026 filing, which covers purchases through October 18.

Two numbers in that table do most of the work. At $81,854, the stack is worth about $5.4 billion more than it cost. A fall in bitcoin of roughly 8% would wipe that out and put the whole position below its average cost, which is where it sat at the end of June, when bitcoin closed at $58,559.

Strategy calls itself the largest institutional holder of bitcoin. How its stack compares with funds, governments and other companies is covered in the guide to who owns the most bitcoin.

How MicroStrategy built the position

It started as a cash-management decision. On August 11, 2020, MicroStrategy announced it had bought 21,454 BTC for $250 million and made bitcoin its primary treasury reserve asset. Michael Saylor, then chief executive and now executive chairman, called bitcoin a legitimate investment asset that could be superior to cash.

The first purchases used the company’s own cash. From December 2020 onward, the buying was funded mostly by selling securities: new MSTR shares through at-the-market (ATM) programs, convertible bonds, and from 2025 a family of perpetual preferred shares listed as STRF, STRC, STRK and STRD. In February 2025 the company started doing business as Strategy, keeping the MSTR ticker.

Look at the last three rows. In the first half of 2026 Strategy added about 173,500 BTC. Between June 30 and October 18 it added roughly 2,500, and the count actually dipped in July.

That dip is new. The Q2 2026 release describes a “BTC Monetization Program” under which the board allows bitcoin sales to fund the USD Reserve, preferred dividends, interest and buybacks. Strategy had sold about $218.4 million of bitcoin under it by July 26. The weekly 8-Ks since then show small purchases funded by MSTR share sales (250 BTC in the week to October 11, 267 in the week to October 18) alongside large repurchases of STRC preferred stock, $192.4 million in a single week in October.

The company that bought bitcoin with everything it could raise is now spending a large part of its capital on its own preferred shares. For an MSTR holder, that shift matters more than any single week’s purchase.

Why Strategy’s earnings are really a bitcoin price report

Since January 1, 2025, Strategy has applied the accounting rule ASU 2023-08, which requires it to mark its bitcoin to fair value at the end of each quarter and run the change through net income. Before that, it could only record impairments when bitcoin fell. Now every move in the bitcoin price lands in earnings, in both directions, whether or not a coin was sold.

The result is that the quarterly profit line tracks one input almost perfectly:

Net income and revenue from Strategy’s quarterly results filed with the SEC; Q3 2026 gain is the company’s unaudited estimate from its October 5 8-K. BTC change is quarter-end to quarter-end, using daily closes from Yahoo Finance.

Six reported quarters, six matches, and the Q3 2026 estimate points the same way: when bitcoin rose, Strategy made money; when it fell, Strategy lost it. In Q2 2026 the unrealized loss on bitcoin was $8.32 billion. Software revenue that quarter was $122.4 million, about 1.5% of the bitcoin swing.

This is why the usual way of reading an earnings report breaks down on MSTR. Diluted EPS, beat or miss against consensus, the price-to-earnings ratio: all of them are bitcoin’s quarter-end price wearing an accounting costume. An EPS estimate for Strategy is in effect a bitcoin forecast. For Q4 2025 the Zacks consensus called for EPS of $46.02; Strategy reported a loss of $42.93 per share after bitcoin fell 23% in the quarter.

By the time Strategy reports, the main number is already public. Anyone with a bitcoin chart and the latest 8-K can estimate the unrealized gain or loss to within a few percent. The company now even publishes that estimate itself a few days after quarter-end, as it did on October 5.

What moves MSTR: bitcoin, and the premium on top of it

If the stock were just a wrapper for bitcoin, it would move one-for-one with it. It doesn’t. From the August 10, 2020 close, the day before the first purchase, to October 19, 2026, bitcoin rose 6.9 times. MSTR rose 11 times. But from its own peak on November 20, 2024, MSTR was down 71% by October 19, while bitcoin was 34% below its October 6, 2025 record.

Two forces sit between the coin and the share.

• The premium (mNAV). Strategy’s market capitalization can be higher or lower than the value of the bitcoin it holds. The ratio between the two, which Strategy publishes on its website as mNAV, expands when investors pay up for Saylor’s ability to raise capital and buy more coins, and shrinks when that appetite fades. In Q3 2025 bitcoin rose 6.5% and Strategy kept adding coins, yet MSTR fell 20.3%. The gap came from the price the market was willing to pay for each bitcoin Strategy held, not from the coins.
• Dilution and leverage. Every ATM sale of MSTR stock adds shares. If the premium is above 1, selling stock to buy bitcoin raises the bitcoin held per share, which is the logic behind the whole model. If the premium falls toward or below 1, issuing stock stops adding bitcoin per share. Debt and preferred stock work the other way: they are fixed claims ahead of common shareholders, so they amplify bitcoin’s moves in the stock.

The quarterly prices show both forces at once. In four of the last seven quarters MSTR moved further than bitcoin in the same direction: +40.2% against +29.8% in Q2 2025, -52.8% against -23.3% in Q4 2025, -30.3% against -14.2% in Q2 2026 and +76.1% against +42.7% in Q3 2026. In Q1 2025 and Q1 2026 it fell less than bitcoin, and in Q3 2025 it went the other way. The amplification is real, but the premium can cancel it or reverse it.

For a trader, MSTR is a position in bitcoin plus a position in the premium. The second one has no chart of its own on most screens, which is why it catches people out.

Where Strategy’s earnings still matter

Earnings are secondary to the bitcoin price for the headline result. They are not irrelevant. The report and the call are where the company explains how it will pay for the structure it has built, and that is what drives the premium.

Four items carry information the 8-Ks don’t:

• The cost of capital. Preferred dividends were $400.7 million in Q2 2026 alone. STRC pays 12% a year, and the company has said it will hold that rate until STRC trades near its $100 stated value.
• Cash coverage. The USD Reserve stood at $4.83 billion on October 18, set aside for dividends and interest. In July management put the coverage at more than 2.1 years; each report updates that figure and says whether bitcoin sales are funding it.
• Debt. Convertible notes outstanding fell to $6.71 billion after a $1.5 billion repurchase in May 2026.
• Buybacks. The board lifted the preferred repurchase authorization from $2 billion to $3 billion in October. A $1 billion MSTR buyback program also exists, unused as of the October 19 filing.

A shareholder vote also lands right before the next report: a special meeting on October 28, 2026 on proposed changes to how Strategy’s preferred dividends are paid. Q3 results follow after the US close on Thursday, October 29. The date, the webinar time and how the stock has reacted on past report days are covered on the MSTR earnings date page.

Even the biggest report-day move fits the pattern. MSTR jumped 26.1% the day after the Q4 2025 results in February 2026, a quarter with a $12.4 billion loss; bitcoin rose 12.5% the same day.

How to read MSTR against bitcoin

Before taking a view on the stock, a short routine puts the two prices in context:

1. Start with the BTC/USD chart. Much of MSTR’s daily move starts there. If bitcoin is flat and MSTR moves 8%, look for news about the premium or the capital structure.
2. Check Monday’s 8-K. It shows how many coins were bought or sold, how the purchases were funded and how many new shares were sold. Heavy MSTR issuance with a falling premium is a warning; small purchases funded mostly by preferred sales point to different priorities.
3. Compare price to the stack. Holdings times the bitcoin price, divided by shares outstanding, gives the bitcoin backing per share. The gap between that and the share price is the premium you are paying, before counting debt and preferred stock that rank ahead of common shares.
4. Mark the dates. Quarter-end decides the reported profit; the report itself mostly adds funding news. The earnings season guide explains why the whole market’s reaction to numbers can differ from the numbers themselves, and earnings trading strategies covers ways to position around a report.
5. Size for both legs. MSTR has often amplified bitcoin’s quarterly moves, up and down. A position sized like a normal stock is in practice a larger bitcoin position than it looks.

Trading Strategy and bitcoin on PrimeXBT

PrimeXBT offers Strategy (MSTR) as a share CFD and bitcoin as a crypto instrument, so both sides of this relationship can be watched and traded from one account. CFDs let a trader go long or short without owning the shares, which suits a stock where the view is often about the gap between MSTR and bitcoin rather than the direction of either. How CFD trading works covers margin and the risks of trading on borrowed exposure.

Saylor’s company once announced its bitcoin buys as a statement of conviction. Today the most telling line in its weekly filing may be the one about the STRC shares it bought back.
