Strategy Bitcoin Holdings Hit 845,050 BTC as Buying Resumes

Strategy bitcoin holdings: how much does the company own, and what did it just do?

Strategy — the company formerly known as MicroStrategy — held 845,050 BTC as of August 30, 2026, putting Strategy bitcoin holdings at roughly $65.3 billion in current value at bitcoin's prior close, against a total cost basis of $63.73 billion and an average purchase price of $75,412 per coin. The company's August 31 8-K, covering the week of August 24-30, discloses that Strategy bought 4,603 BTC for $369.7 million at an average price of $80,318 — its first disclosed bitcoin purchase since June 22, and the filing that ends a run of nine straight weekly filings with no purchase, three of which were outright sales. The buying was funded entirely by fresh stock sales, not by the cash reserves Strategy had spent the prior weeks building up.

That resumption is the whole story this week, and it is worth stating plainly before anything else: after selling bitcoin below its own cost basis twice in early August, Strategy went back into the market and bought at a price roughly 26-29% above where it had just sold. Both facts are in the same filing, and both matter for reading Strategy bitcoin holdings and MSTR bitcoin treasury data going forward — this is no longer a company that only accumulates.

A note on sourcing before the rest of this piece: bryptoflows' own treasury dataset was still showing the August 24 filing — direction "none," holdings unchanged at 840,447 BTC — when this article was written, a lag of roughly ten days against the most recent 8-K. The financing side of the same dataset had already ingested the August 31 filing's ATM figures, which is what surfaced the gap. Every bitcoin-holdings figure in this piece for the August 24-30 period is therefore read directly from the primary filing — accession number 0001193125-26-375463, filed August 31, 2026, covering the period August 24 through August 30 — rather than from bryptoflows' own materialized API, and cross-checked against reporting from The Block, crypto.news and FinanceFeeds. Figures for the financing programs, share structure and the historical filing series below do come from bryptoflows' own API, which is current.

Nine weeks of no purchases, then a reversal

The filing history is unambiguous about the shape of the pause. Strategy's last disclosed acquisition before this week was June 22 (+520 BTC). Every weekly filing after that through August 24 reported either no bitcoin transaction or a sale:

Net effect: holdings fell from 847,363 BTC on June 22 to 840,447 BTC on August 24, a reduction of 6,916 BTC over nine filings, entirely from the two August sales plus the July 6 sale. Both August sales were realized losses against the company's own average cost basis at the time — proceeds of roughly $64,000 per coin against a cost basis in the mid-$75,000s. That pattern, not steady accumulation, is what the August 31 filing interrupted.

The reversal was telegraphed a day early: Strategy executive chairman Michael Saylor posted "We're ₿ack" on X on August 30, and the 8-K followed on schedule. The Block reported the purchase and holdings figures matching the filing, and FinanceFeeds, crypto.news and Invezz each covered it as the end of a roughly two-month pause. bryptoflows' own filing history counts nine weekly 8-Ks without a purchase, June 29 through August 24.

The purchase price problem: buying 26-29% above where it just sold

The most specific, checkable finding in this filing is a mismatch in execution price. Strategy sold bitcoin at $63,957 (August 3) and $64,262 (August 10), then bought at $80,318 (August 31) — a price 25.6% and 25.0% above those two sales, respectively. Reported outside coverage puts the gap at closer to 29% against the lower end of the company's recent sale range. Whichever comparison is used, the direction is the same: Strategy realized losses selling bitcoin in early August and then paid a meaningfully higher price to buy it back three weeks later.

That is not necessarily a mistake on its own terms — cost-basis comparisons only tell you about the past — but it is a fact about execution, not interpretation, and it belongs in any account of MSTR bitcoin sales and purchases this year. It also nudged the blended average cost basis up, from $75,385 before this purchase to $75,412 after it — a small move because the new tranche is under 0.6% of total holdings, but a move in the expensive direction.

As of bitcoin's September 2 close of $77,319, the newly purchased 4,603 BTC batch is itself underwater: bought at $80,318, it is worth about $355.9 million against its $369.7 million cost, an unrealized loss of roughly $13.8 million on that specific tranche alone. The position as a whole is a different picture — see below.

The position's current value against its cost basis

Zooming out to the full 845,050 BTC holding, the picture is a modest unrealized gain rather than a loss. At bitcoin's September 2 close of $77,319, the position is worth approximately $65.34 billion against a total cost basis of $63.73 billion — an unrealized gain of roughly $1.61 billion, or about 2.5% above cost. Bitcoin has traded in a tight $76,900-$78,200 band through the first few sessions of September, so that figure has not moved materially since the filing.

That gain sits on top of a cost basis built almost entirely during 2025 and early 2026 at prices well below current levels — the August 31 purchase is one of the few tranches bought above where bitcoin now trades, and it is a reminder that "average cost basis" blends years of very different entry prices into one number that can mask a specific week's bad timing.

What paid for the purchase, and what else the same stock sale funded

The August 31 filing is explicit about where the money came from and where all of it went, which is unusual detail worth passing through directly. Strategy sold 4,531,421 shares of MSTR common stock via its at-the-market program during the week, for $602.8 million in net proceeds. That was split four ways:

Two things stand out. The purchase was funded by issuing new common shares that week, not by drawing down the roughly $1.6 billion USD Cash pool the company had been building — that pool grew slightly further, to $1.61 billion, rather than being spent. And less than two-thirds of the week's capital raise went toward bitcoin at all; a comparable share went to preferred-stock obligations and buybacks. Corporate bitcoin treasury demand from Strategy this week was real but partial, funded by dilution rather than by the liquidity reserve built for this purpose.

Financing capacity: how much more Strategy could buy without new authorization

bryptoflows tracks undrawn capacity across Strategy's five capital programs as a live figure, and as of the August 31 filing it stands at $44.34 billion: $19.09 billion still available under the MSTR common ATM, $17.51 billion under STRC, $4.01 billion under STRD, $2.10 billion under STRK, and $1.62 billion under STRF.

Set against the position's roughly $65.34 billion current market value, that undrawn capacity equals about 68% of what the entire bitcoin holding is worth today — Strategy could, in principle, fund a purchase worth more than two-thirds of its existing position without seeking new share or debt authorization from shareholders. That is a large number and, per this week's filing, not one the company is drawing down quickly: $602.8 million raised bought $369.7 million of bitcoin, well under 1% of available capacity in a single week. Financing capacity measures what Strategy could do, not what it is doing.

Dilution: what 41 million new shares mean per unit of bitcoin

The capital that funds these purchases is not free. Against a July 24 baseline of 384.2 million reported shares, bryptoflows estimates Strategy has issued roughly 41.3 million additional shares through ATM sales, taking estimated shares outstanding to about 425.5 million — an increase of about 10.7% in five weeks. The resulting metric bryptoflows tracks, bitcoin held per 1,000 shares, currently sits at 1.975 BTC. Every new share sold to fund a purchase dilutes existing holders' claim on the underlying coins unless the purchase is accretive relative to the stock's own valuation — a comparison that depends on how MSTR is priced against its bitcoin holdings, and one this dataset does not settle.

How the treasury channel compares to the ETF channel this week

US spot bitcoin ETFs absorbed 49,041 BTC across all of August, per bryptoflows' own flow data covered in Tuesday's supply-absorption piece. Strategy's single week of buying — 4,603 BTC — equals roughly 9.4% of that entire month's ETF-channel absorption, in one filing. It is a reminder that corporate treasury demand, even paused for two months, can still move at a meaningful fraction of the ETF category's pace in the week it chooses to act. For the eight prior weeks, the comparison ran the other way: the ETF category was net absorbing bitcoin while Strategy was a net seller, a divergence Tuesday's piece and Wednesday's macro brief both flagged as an ETF-only story. This week's filing does not reverse that framing for August as a whole — Strategy was still a net seller of 3,328 BTC across the full month before this purchase — but it complicates it for September's opening week.

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 August 30 says nothing about September 3, and the swing between the position's overall gain and the underwater new tranche shows how quickly that number moves. The company continues to fund purchases primarily through new share issuance rather than operating cash flow — a structural feature of its model, not a one-week decision — and this week's raise funded bitcoin, preferred dividends and buybacks simultaneously; future weeks could allocate that capital differently. Weekly 8-K filings are point-in-time disclosures with a built-in lag, and — as this article's own sourcing problem illustrates — even a well-run pipeline built to track them can fall behind a live filing by more than a week. Finally, MSCI's consultation on whether Strategy's classification changes given its bitcoin concentration remains open, with comments due September 30 and a decision expected October 16; nothing in this filing resolves that either way.

Two other public companies run comparable treasury strategies in different assets — BitMine (BMNR) in ether and Hyperliquid Strategies (PURR/HYPE) — with their own dedicated coverage on this site; this piece is Strategy-only.
