Strategy Bitcoin Holdings Hit 848,000 BTC, Q3 Flips to Gain
Strategy bitcoin holdings climb to 848,000 BTC as Q3 flips to a $20.91 billion gain
Strategy bitcoin holdings now stand at 848,000 BTC, after the company — renamed from MicroStrategy in 2025 but still widely searched under its old name — disclosed on October 5 that it bought 334 BTC for $28.7 million, split between new stock sales and cash on hand. That is a small purchase next to some of this year's filings, and it is not the most interesting number in the same filing: Strategy's own preliminary Q3 financial update shows its bitcoin position generated a $20.91 billion fair-value gain for the quarter, reversing a loss position that existed as recently as June 30. Holdings carry a total cost basis of $63.97 billion, or $75,440.70 per coin.
What did Strategy's October 5 filing actually disclose?
The 8-K, filed October 5 and covering bitcoin activity through October 4 (accession 0001193125-26-413164, confirmed against SEC EDGAR for this piece), splits into two reporting stubs: September 28–30 and October 1–4. The first stub was quiet — no bitcoin bought or sold, holdings unchanged at 847,666 BTC. The second stub is where this week's activity sits: 334 BTC acquired for $28.7 million at an average price of $85,838.80, with the filing itself breaking down the funding — $15.7 million came from net proceeds of 92,894 MSTR shares sold under the company's at-the-market program, and $13.0 million came from USD Cash, the discretionary pool Strategy keeps for general treasury purposes. That is a genuine split, not purely dilutive and not purely balance-sheet funded, which is itself a change from the two filings before it, where September 21's buy was entirely cash-funded and September 28's was entirely stock-funded.
The same filing shows Strategy continuing to repurchase its own preferred stock. Under its Digital Credit Securities Repurchase Program, the company bought back 1,033,168 shares of STRC stock for $102.6 million in the September stub and a further 740,634 shares for $73.7 million in the October stub — funded by USD Cash and, in the September period, interest earned on Strategy's cash balances. That pushed the program's remaining authorization down to $547.2 million, from $620.9 million two weeks earlier. A separate $1.0 billion MSTR common-stock buyback authorization remains completely untouched, unchanged across both reporting dates. Outside the bitcoin and buyback activity, the filing also discloses $142.5 million drawn from the USD Reserve — the pool set aside for preferred dividends and debt interest — to cover those payments during the period, leaving USD Reserve at $4.88 billion and USD Cash at $833.4 million as of October 4, both down from $5.02 billion and $1.00 billion two weeks prior.
How much bitcoin does Strategy own, and what is its cost basis?
Strategy's average cost per bitcoin is now $75,440.70, up marginally from $75,436.60 two weeks ago — this week's purchase price of $85,838.80 sits well above the running average, but a 334-BTC buy barely moves a base of 848,000 coins. Zooming out to the full year is more informative than any single week: Strategy entered 2026 with roughly 672,500 BTC and has added a net 175,500 BTC since, a 26% increase in holdings, while the average cost per coin has crept up only about 0.6% over the same stretch — a reminder that volume and average price move somewhat independently when a position this large keeps changing.
That growth has not been a straight line. Last week's treasury piece covered in detail the four weeks this year where Strategy disclosed bitcoin sales rather than purchases — June 1, July 6, August 3 and August 10 — each one priced below the company's running average cost at the time, meaning each was a realized loss on a mark-to-cost basis. This filing extends a different streak: Strategy has not disclosed a single bitcoin sale in the eight weekly filings since August 10. Every one of those eight weeks has read either "none" (a disclosed zero) or "acquired." October 5 is the third "acquired" filing in a row, following September 21 and September 28.
Has Strategy's bitcoin position actually turned a profit this quarter?
This is the filing's most substantive disclosure, and it is the kind of detail that gets lost when coverage works from a press release headline rather than the filing itself. Strategy's preliminary Q3 2026 financial update — not yet reviewed or audited by KPMG, the filing is explicit about that — estimates a $20.91 billion gain on digital assets for the three months ended September 30, against an associated $1.88 billion deferred tax expense. As of September 30, the filing puts the carrying value of Strategy's bitcoin holdings at $70.82 billion.
The tax detail is the tell. Strategy discloses that, as of June 30, 2026, the fair value of its bitcoin holdings was below cost — a loss position — which had produced a $4.12 billion deferred tax asset and a corresponding valuation allowance against it. By September 30, fair value had moved back above cost, so that asset was reversed and the valuation allowance released, which is why the quarter's net deferred tax expense came in at $1.88 billion rather than the roughly $6.00 billion it would otherwise have been. Read plainly: Strategy's bitcoin position was underwater on a fair-value basis at the end of the second quarter, and the $20.91 billion swing this quarter is largely bitcoin's own price recovery working through GAAP fair-value accounting, not a change in what Strategy bought or sold. It is a reminder of how large the quarter-to-quarter swings in Strategy's reported earnings can be purely from marking a single, undiversified asset position to market.
What is the position worth today, against that cost basis?
Bitcoin's own price has pulled back since the September 30 marks above. bryptoflows' own live price feed showed bitcoin trading around $83,000 as of this writing on October 8, down from the $85,738 close on filing day (October 5) and the $84,837–$87,235 range earlier in the week, after falling from an $85,547 open to an $83,302 close on October 7 alone. At a price near $82,990, Strategy's 848,000 BTC is worth in the neighborhood of $70.4 billion against its $63.97 billion cost basis — an unrealized gain of roughly $6.4 billion, or about 10% above cost. That is narrower than the 10.7% cushion implied by the September 30 marks in the Q3 update above, consistent with bitcoin's own pullback this week rather than anything Strategy did. As always with this comparison, it mixes bryptoflows' own SEC-sourced cost basis with bryptoflows' own live price feed and should be read as directional, moving with bitcoin's price day to day.
How much financing capacity does Strategy still have?
Across its five at-the-market programs — common MSTR stock and the STRC, STRD, STRF and STRK preferred series — Strategy's undrawn issuance capacity totals $44.09 billion as of this filing, essentially flat from two weeks ago since only $15.7 million of common stock was sold under any program this period. Set against the position's roughly $70.4 billion current value, that capacity equals about 63% of the entire bitcoin position's value — financing Strategy could in principle draw on without a new shareholder vote or fresh authorization. That $44.09 billion issuance capacity is a separate pool from the $547.2 million left under the preferred-stock 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 number, and each tells a different story about what Strategy could do next.
MSTR bitcoin treasury demand against the ETF channel this week
US spot bitcoin ETFs, the other major channel of institutional bitcoin demand bryptoflows tracks, had a rougher stretch over the same days. Across the five most recent reported sessions — October 1 through October 7 — the category's net flow was -$163.3 million: a +$102.7 million Thursday and +$189.9 million Friday gave way to a -$89.8 million Monday, a +$118.8 million Tuesday and a sharp -$484.9 million Wednesday. Strategy's +$28.7 million bitcoin purchase during the overlapping October 1–4 window is small in absolute terms, but it ran in the opposite direction of the ETF category's net over the same stretch — the treasury channel added to its position in a week where the ETF channel, on net, gave bitcoin back. Tuesday's supply-absorption piece and Wednesday's macro brief both flagged this same filing in passing as part of their own coverage of ETF and macro dynamics; this is the full accounting of what it means for Strategy specifically. Neither comparison should be read as a trend — the two channels have swapped which one is larger several times this year — but a single week of divergence is itself informative about how differently the two sources of demand are behaving right now.
Risks and open questions the filings don't resolve
None of the figures above are a recommendation on MSTR stock; this is a read of what Strategy disclosed, not investment advice. A few limits are worth stating plainly. Strategy's bitcoin position remains unhedged and entirely mark-to-market, which is exactly what produced this quarter's $20.91 billion swing and last quarter's loss position — a structure that works in both directions, and the same arithmetic that produced a $20.91 billion gain this quarter could just as easily reverse one. Senior claims ahead of common shareholders — $6.67 billion of long-term debt plus $15.46 billion of preferred stock at its liquidation preference, per Strategy's 10-Q for the quarter ended June 30 — total $22.13 billion and sit ahead of any value flowing to equity, regardless of where bitcoin trades; that figure is a quarterly snapshot and predates several of the filings discussed here. On dilution, Strategy's estimated share count has grown to roughly 428.5 million, up from a 384.2 million baseline in late July, and the bitcoin-per-1,000-shares ratio that measures whether buying is outpacing dilution sits at essentially the same level as two weeks ago — this week's share issuance roughly kept pace with the bitcoin added, rather than clearly outpacing or lagging it. Weekly 8-Ks are also point-in-time disclosures that lag by construction: this filing is accurate as of October 4 and says nothing about what has happened since, including bitcoin's own price move this week. One other open item: MSCI's review of whether to exclude bitcoin treasury companies, Strategy included, from its global equity indexes is still pending, with a decision due October 16 — nothing in this filing bears on that outcome. Two other public companies run comparable corporate 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.
