Strategy

Not bitcoin. You own equity in a listed company whose balance sheet holds 843,775 bitcoin, and those are different instruments with different risks. There is no redemption mechanism: you cannot exchange shares for coins, and nothing forces the share price to track the holdings.

In practice it usually trades above the value of the bitcoin it holds, sometimes far above. That premium is the thing to understand, because it is what the whole structure runs on. Strategy issues shares at the elevated price and buys more bitcoin with the proceeds, which adds bitcoin per share and justifies the premium that made the issuance worth doing. It works while the premium persists.

It also runs in reverse. If the shares trade below the value of the holdings, issuing equity destroys bitcoin per share instead of creating it, and the mechanism that drove accumulation stops. The reflexivity is symmetrical; only the upward half tends to get modelled.

A spot bitcoin ETF gives exposure without any of this — no premium, no debt, no corporate structure, and a redemption mechanism that holds the price to the asset. The case for MSTR over an ETF is a bet on that premium and on the management that sustains it, which is a different bet from a bet on bitcoin.

The bitcoin was largely bought with borrowed money — convertible notes, plus continuous at-the-market equity issuance. Leverage explains both the scale of the position and the risk attached to it.

Convertible debt is the gentler form. It converts to equity if the share price is high enough, which in a rising market dilutes rather than demands repayment. In a falling market it becomes debt with a maturity date, against an asset that has fallen too, and the company faces that repayment without the option of issuing equity cheaply to meet it.

The preferred series — STRF, STRC, STRK, STRD — add obligations senior to common stock, meaning holders of MSTR sit behind them if anything has to be paid.

Nothing here says the structure fails. It has been maintained through drawdowns that would have broken a less deliberate execution. What it says is that the position is leveraged, the leverage is why the returns have outpaced bitcoin, and the same arithmetic works in the other direction with nothing to arrest it.
