Strategy Bitcoin Holdings Flat, $926M Spent on Buybacks

Strategy bitcoin holdings: flat at 845,050 BTC as buybacks keep running

Strategy — the company formerly known as MicroStrategy — holds 845,050 BTC, worth roughly $64.4 billion at Wednesday's close, against a total cost basis of $63.73 billion and an average purchase price of $75,412 per coin. Strategy bitcoin holdings did not change this week: the company's September 14 Form 8-K, covering September 8 through September 13, discloses no bitcoin purchases and no bitcoin sales — the third flat filing in the last four, with the only activity in that stretch a single 4,603 BTC purchase on August 31. Bitcoin has traded lower over the past few sessions, and the position's unrealized gain has narrowed to roughly 1% above cost, one of the thinnest cushions since Strategy's buying accelerated in 2024.

That headline — no bitcoin bought, none sold — is not the most interesting fact in the filing. Read alongside the six 8-Ks before it, the pattern underneath is that Strategy has now spent cash buying back its own preferred stock every single week since early August, in larger and more consistent amounts than it has put toward bitcoin over the same stretch.

What this week's filing actually says

Strategy's September 14 8-K (accession 0001193125-26-389858) states plainly that between September 8 and September 13, Strategy "did not sell any shares under its at-the-market offering program and did not purchase or sell any bitcoin." Holdings stand at 845,050 BTC, acquired at an aggregate cost of $63.73 billion, or $75,412 per coin — unchanged figures because nothing moved them.

What the company did do: spend $139.3 million of a pool it calls "USD Cash" repurchasing 1,420,467 shares of STRC, its Variable Rate Series A Perpetual Stretch Preferred Stock, under the company's Digital Credit Securities Repurchase Program. That program's authorization was doubled from $1.0 billion to $2.0 billion on September 8 — last Thursday's treasury piece covered that decision in detail — and $1.05 billion remains available under it after this week's purchase. Strategy also discloses a separate, entirely untouched $1.0 billion authorization for buying back MSTR common stock; no shares have been repurchased under that program in any of the filings reviewed for this piece. USD Reserve, the pool set aside for preferred dividends and debt interest, stood at $5.10 billion as of September 13, and USD Cash — the more discretionary pool that also funds bitcoin purchases when Strategy chooses to make them — stood at $1.30 billion.

Seven straight weeks, $926 million to buybacks

Widen the lens past this single filing and the buyback program looks less like a one-off and more like a standing weekly commitment, regardless of what Strategy does with bitcoin:

Summed across those seven filings, Strategy has spent $925.8 million in cash repurchasing roughly 9.67 million STRC shares — a figure that has risen every single week — against a single bitcoin purchase of $369.7 million (paid for with freshly issued stock, not cash) and two bitcoin sales that together generated $213.3 million in proceeds. Net bitcoin holdings rose by 1,275 BTC over the seven weeks; net cash spent buying back the company's own preferred stock ran to nearly a billion dollars. The MSTR common-stock buyback authorization, by contrast, has not been used once in any of these filings — the entire repurchase story so far is a preferred-stock story.

Why Strategy's biggest 2026 bitcoin sales came in below cost

Zoom out further and nearly every disclosed bitcoin sale Strategy has made in 2026 was priced below the company's own average cost basis at the time. The one exception is trivial: a 32 BTC sale on June 1, priced at $77,135 against a then-average cost of $75,699 — a rounding-sized transaction next to what came after it. The sales that actually moved the position were priced the other way: 1,363 BTC on June 29–30 at an average $59,256; 2,225 BTC on July 1–5 at $60,773; 1,638 BTC on August 3 at $63,957; and 1,690 BTC on August 10 at $64,262 — a combined 6,916 BTC for $429.3 million in proceeds, against a blended average cost basis that sat between roughly $75,400 and $75,600 across that period. Comparing each sale price to the company's own disclosed average cost at the time implies a realized loss on those coins of roughly $92.5 million — a directional figure, since the filings do not disclose which specific purchase lots were sold, but one built entirely from Strategy's own reported numbers rather than an outside estimate.

The filings are explicit about where the money went: proceeds from the June/July sales funded preferred-stock dividends and replenished the USD Reserve; the August sales funded both dividends and STRC buybacks directly. Strategy's own accounting confirms the sales were not a rounding error. For the quarter ended June 30, 2026, the company reported an $8.32 billion loss on digital assets, $8.31 billion of it unrealized, and disclosed that because the cost basis of its bitcoin exceeded fair value at quarter-end, it recorded a full valuation allowance against the related deferred tax benefit and deferred tax asset. An earlier treasury piece covers the pause-then-reversal arc around these sales week by week; the point relevant here is that selling below cost to fund cash needs elsewhere has become a repeated feature of 2026, not an isolated event, even as the company has also bought back in since.

How thin is the cushion now?

With holdings unchanged, the position's value moves only with bitcoin's price. Bitcoin closed at $76,180 on Wednesday, September 16 — bryptoflows' most recent complete session — putting the 845,050 BTC position at approximately $64.38 billion against the $63.73 billion cost basis. That is an unrealized gain of roughly $649 million, or about 1.0% above cost. That cushion has been shrinking through the month: this column's September 10 piece put it at 3.8% using a $78,275 close, and Wednesday's macro brief cited a live price of $75,877 that implied a cushion of just 0.6%. Wednesday's own close recovered part of that. The point is not any single reading — it is that a position holding steady at 845,050 BTC has swung from a multi-billion-dollar cushion to something close to breakeven purely on price, without a single share of the underlying position changing.

Financing capacity: $44.3 billion undrawn, unchanged since August 31

Strategy's at-the-market equity and preferred-stock offering programs — the capital it could raise by issuing new securities — still show $44.34 billion of undrawn capacity across five programs, per bryptoflows' financing dataset, unchanged since the August 31 filing because no new shares have been sold under any ATM program in the two filings since. Set against the position's roughly $64.38 billion current value, that is about 69% of the entire bitcoin holding in additional capacity Strategy could, in principle, deploy without new shareholder authorization. That figure is a separate pool from the $1.05 billion left under the Digital Credit Securities Repurchase Program and the untouched $1.0 billion MSTR buyback authorization discussed above — three distinct levers on different parts of the balance sheet, not one combined number.

Corporate treasury demand vs. the ETF channel

Over the trailing 20 trading sessions through September 16, bryptoflows' own institutional-analytics feed puts US spot bitcoin ETF net flow at roughly $2.29 billion. Strategy's own treasury contribution over a comparable stretch — the trailing four weekly filings — is a single 4,603 BTC purchase worth $369.7 million, and zero in three of those four weeks, including this one. On bryptoflows' composite institutional score, the treasury-accumulation component reads 17.96 out of 100 this week, contributing just 2.5 of the composite's 25.6 total, in a period the model classifies as "moderate accumulation" with low component agreement — consistent with a corporate treasury channel that has gone mostly quiet while directing its cash elsewhere. Two other public companies run comparable treasury strategies in other assets, BitMine (BMNR) in ether and Hyperliquid Strategies (PURR/HYPE), each with its own coverage on this site; this piece is Strategy-only.

Risks and open questions the filings don't resolve

A few things are worth stating plainly. Strategy's bitcoin position is unhedged and marked to a price that moves daily; a filing accurate as of September 13 says nothing about September 17, and the swing in this piece's own cushion estimate over the past week shows how quickly that number moves. The company's preferred-stock buyback program is now running at a faster and more consistent cash pace than its bitcoin-buying program, funded from a cash pool (USD Cash) that management could just as easily direct toward bitcoin in a future week — nothing in the filings commits it either way. The MSCI consultation on whether Strategy's index classification changes given its bitcoin concentration remains open, with comments due September 30 and a decision expected October 16; nothing in this week's filing moves that forward. And the broader macro backdrop turned tighter this week — the Federal Reserve raised its target rate 25 basis points to 3.75%–4.00% on Wednesday, its first hike since 2023 — a shift Wednesday's macro brief covers in full and that this piece flags only because it is the environment this week's near-breakeven cushion sits in.

None of the above is investment advice or a recommendation about MSTR stock.
