Three days ago the question was whether Strategy had bought well. On Thursday the market answered it, for now, in the company’s favour. The 4,603 bitcoin that Strategy disclosed on 31 August, bought between 24 and 30 August at an average of $80,318 including fees, were worth $12.10 million less than they cost at Thursday morning’s price of $77,690.09. Bitcoin then rose 5.127% on Bitstamp to close at $81,265.00 — its first close above $81,000 since 14 May — and at that print the tranche is worth $374.06 million against a cost of $369.70 million: a profit of $4.36 million, or 1.179%. The swing from Thursday morning to Thursday close is $16.46 million on a position that has existed for ten days. As of 06:10 UTC on Friday, at $81,043.98, the profit is $3.34 million.

Strategy’s common stock did what it does on a day like that, times three. MSTR closed at $144.82, up 17.56% from $123.19, on 43.87 million shares, per S&P Global Market Intelligence data via StockAnalysis; the intraday high was $144.92. It was the stock’s largest one-day gain and its highest close in the fifty sessions on the table we pulled, which runs back to 25 June; the previous best day in that span was 19 August (+12.68%) and the previous highest close 27 August ($137.40). From the 18 August close of $92.52 the stock is up 56.5% in twelve sessions. The ratio of the stock’s move to bitcoin’s on Thursday was 3.4 to 1, which is at the upper end of what the share has delivered on bitcoin’s big days in this run: on 21 August, bitcoin’s +7.283% produced +6.10% in MSTR, a ratio below one.

Own computation. Thursday-morning column from Thursday’s markers piece; close from Bitstamp BTC/USD; Friday snapshot from the partial Bitstamp daily candle at 06:10 UTC. Cost figures from the 31 August 8-K.

The constant we asked readers to carry from Tuesday’s piece is doing the work here: each $1,000 in the bitcoin price moves the value of Strategy’s holding by $845.05 million, so a $3,963 close-to-close gain revalued the position by $3.35 billion between Wednesday and Thursday. The position has been in profit throughout; the tranche had not been, and that was the point of the 1 September piece. The company paid 1.757% above the volume-weighted price of its own purchase window, $6.39 million more than the window’s average trade, and that gap has not changed — a rally does not make an execution better, it makes it matter less. Guide #38 separates the two questions for this reason: whether the price paid was good relative to the window it was paid in, and whether the asset went up afterwards, are different facts, and on Thursday the answers are still no and now yes.

H1 settled: the marker was the company’s own entry price

H1 was set on 1 September as a Bitstamp daily close at or above $80,318 on or before 30 September 2026. It was chosen because it made the marker exactly as hard as the question “did they buy well” on the company’s own terms: if bitcoin could not close above the price Strategy paid within a month, the purchase would look poor by the company’s own clock, and if it could, the desk’s criticism of the execution would have to share the page with a profit. At the 1 September print of $78,979.03 the bar required +1.695%; by Wednesday’s close it required +3.902%; Thursday delivered +5.127%. H1 settles as a pass on the 3 September close of $81,265.00, 27 days before its deadline, by a margin of 1.179%. We record it without adjustment: the piece that said the tranche was underwater was correct on its date, the marker that said the question was open was correct on its date, and the close that settled it is a public number.

What the settlement does not do is retire the criticism. The comparison that mattered in the 1 September piece was between $80,318 and the $78,930.87 volume-weighted average of the seven days Strategy was buying. That is a statement about execution inside a window, and it is as true at $81,265 as at $77,690. The 8-K also disclosed that only 61.3% of the $602.8 million raised through the at-the-market programme in the period went into bitcoin, with $151.8 million to STRC buybacks, $50.7 million to STRC dividends and $30.0 million to cash reserves. Thursday’s rally changed the value of the bitcoin; it did not change where the other 38.7% went.

The sell side moved the same day

B. Riley raised its MSTR price target to $175 from $155 on Thursday, per TheFly, two days after Alliance Global initiated coverage with a Buy and a $217 target, and eight days after Bernstein cut its target to $350 from $450. Three targets in eight days spanning $175 to $350 on a stock that closed at $144.82 is a spread of opinion about the premium, not about the bitcoin; the bitcoin is a public number times 845,050. The company also disclosed on Monday, per TheFly, a US-dollar reserve of $5.1 billion as of 30 August, which is the figure that makes this week’s open question — did it buy again — a question of choice rather than capacity. At Thursday’s close, $5.1 billion buys roughly 62,800 coins.

Two things to hold apart in Thursday’s stock move. Strategy’s share is a levered claim on the bitcoin plus a premium that expands and contracts with sentiment, and a 17.56% move on a 5.13% bitcoin day is mostly the second. The proper test, which our earnings guide sets out, is the change in the market value of the equity against the change in the value of the coins: $3.35 billion of coin revaluation between Wednesday’s and Thursday’s closes, against an equity that rose 17.56% from whatever its Wednesday capitalisation was. We do not have a verified share count as of Thursday — the company sold 4.53 million shares in the last disclosed period alone — so we are not printing a market-cap or mNAV figure this morning; a figure we could not verify would be worse than none. The stock’s after-hours print was $143.50, down 0.91% from the close.

What the calendar does next, and the marker

Strategy’s purchase disclosures come as 8-Ks on Monday mornings covering the prior week. Monday 7 September is Labor Day and US markets are closed, so the next filing window is Tuesday 8 September, and it would cover purchases between 31 August and 6 September — a week in which bitcoin has traded from $76,228.56 (Wednesday’s low) to $82,280.62 (Thursday’s high), and in which the company’s last disclosed average of $80,318 sits roughly in the middle. If the company bought, the average will again be comparable to the window’s volume-weighted price, and we will run the same seven checks. If it did not, with $5.1 billion of dollars on hand and the stock up 17.56%, that is a decision worth the same attention.

As standing practice we mark one falsifiable claim on this. M1: an 8-K filed by Strategy on or before Tuesday 8 September 2026 discloses the purchase of at least one bitcoin during the period 31 August to 6 September. No filing by the close of business on the 8th, or a filing that discloses zero purchases, settles M1 as a fail. We have no view on the outcome; the company bought once in the ten weeks between 22 June and 30 August, and the marker exists so that the pattern across tranches — the seventh of Guide #38’s checks — can be graded against filings rather than against Sunday posts. Bitcoin, for the record, was $81,043.98 on Bitstamp at 06:10 UTC, 0.272% below Thursday’s close, with the August jobs report due at 08:30 ET.
