Strategy bought no bitcoin in the week of 31 August to 7 September, its Form 8-K filed with the SEC on Monday 8 September states, one week after a $369.7 million purchase that Michael Saylor had previewed with the words “We’re Back.” The filing’s language is the standard one: “during the period between August 31, 2026 and September 7, 2026, Strategy did not sell any shares under its at-the-market offering program and did not purchase or sell any bitcoin.” Holdings are stated as “approximately 845,050 bitcoin that were acquired at an aggregate purchase price of $63.73 billion and an average purchase price of approximately $75,412 per bitcoin, inclusive of fees and expenses.” The desk set marker M1 on 31 August — a Strategy 8-K by 8 September showing at least one bitcoin bought between 31 August and 6 September — as the test of whether “back” meant a programme or a purchase. M1 fails. One tranche is a purchase.
What the company did spend money on is in the same filing. Between 31 August and 7 September Strategy repurchased 1,810,885 shares of STRC, its variable-rate preferred, for $176.3 million under what it calls its digital credit securities repurchase programme, and its board “approved an increase in the aggregate purchase price authorized” under that programme “from $1.0 billion to $2.0 billion,” leaving $1.19 billion available as of 7 September. The filing puts the USD Reserve at $5.10 billion and USD Cash at $1.44 billion at 7 September. Cointelegraph’s Monday headline was “Strategy skips Bitcoin buy to repurchase $176M of STRC preferred shares”; Yahoo Finance led with the doubling of the buyback. Both are the same fact read from opposite ends: in a week when bitcoin’s Bitstamp closes ran from $77,301.83 to $81,265.00, the company’s marginal dollar went to supporting the price of the instrument it sells to fund bitcoin purchases, not to bitcoin.
The tranche, session by session
The 4,603 coins bought at an average $80,318 in the week of 24 to 30 August — above the window’s volume-weighted price, as the desk showed on 1 September — have now had ten Bitstamp closes against them, from 31 August to 9 September. Two were above the average: 3 September’s $81,265.00, which settled marker H1, and 6 September’s $80,338.98, $20.98 above. The other eight were below, the last three consecutively: 7 September $79,090.41, 8 September $78,449.00, 9 September $78,281.65. At Wednesday’s close the tranche is $2,036.35 a coin under water, $9.37 million on the lot, and the whole holding of 845,050 coins, at an average of $75,412, is $2,869.65 a coin in profit, or about $2.42 billion — the older coins carry the newer. At the desk’s 06:10 UTC partial of $78,382.35 on Thursday the tranche gap was $1,935.65. Marker U1, set Monday, asks for Friday’s close at or above $80,318; it needs +2.60% in two sessions.
What the STRC buyback is, and why it competes with bitcoin
STRC is the perpetual preferred whose dividend rate Strategy adjusts monthly to keep it trading near par; it is the company’s largest source of new money and, as the desk noted on 18 August and again on 25 August, its issuance has run alongside weeks of zero bitcoin bought. The repurchase programme is the other side of that machine: when STRC trades below par the company buys it back, which supports the price at which it can next issue. In the week to 7 September the company bought $176.3 million of it and no bitcoin, and raised the ceiling on such purchases to $2 billion. The reading is not that Strategy has stopped buying bitcoin — one week is one week, and the $5.10 billion USD Reserve is unchanged — but that the order of operations, this week, was: defend the funding instrument first. A reader of the desk’s 8-K field manual will recognise the three numbers to carry forward: coins (845,050, unchanged), average cost ($75,412, unchanged), and cash ($1.44 billion USD Cash, $5.10 billion USD Reserve).
Elsewhere in the treasury table
CoinDesk’s Monday live coverage recorded Strive adding 1,375 BTC to reach 24,531, so the week’s corporate bitcoin buying came from a smaller balance sheet than Strategy’s. The comparison the desk keeps is to the spot ETFs, which Farside shows taking in $986.7 million in the week of 31 August to 4 September — about 12,300 coins at $80,000, or roughly 2.7 tranches the size of Strategy’s last — and then giving back $166.8 million on Tuesday and Wednesday of this week. Field Guide #38 is the desk’s method for judging whether a treasury company bought well; the question this week is the prior one, whether it bought at all.
The marker
As standing practice we mark one falsifiable claim. Z1: Strategy’s next weekly 8-K, covering the period that begins 8 September 2026 and filed on or before Tuesday 15 September, reports at least one bitcoin purchased in that period. The reasoning for: the company has $1.44 billion in USD Cash on its own account, bitcoin has closed below its last tranche for three sessions, and the programme’s stated purpose is to accumulate bitcoin, not preferred stock. The reasoning against: last week’s marginal dollar went to STRC, the buyback authorisation was doubled rather than left alone, and the company’s own pattern since mid-August has been to buy bitcoin in one week out of four. If Z1 passes, M1 was a pause; if it fails, the 24 to 30 August tranche was the exception and the buyback is the rule.
