Every correction to a figure or date the Strategy 1M BTC tracker served publicly, with the before and after values, the reason, and the primary source that settled it. These entries are part of the single Reconciliation Ledger.
as of 2020-09-14
The Sep 14, 2020 purchase-history row carried a running average purchase price of $11,035.995 in the page’s data (served in the page’s HTML; not displayed). No filing states it: it is the plain mean of the Aug 10 and Sep 14 rows’ per-purchase prices ($11,652.84 and $10,419.15), not an average cost of the bitcoin held. The row’s source, the 8-K filed September 15, 2020, states that the company held 38,250 bitcoins acquired at an aggregate purchase price of $425 million, and states no average. The row now carries no running average. Its displayed BTC acquired, cost and holdings (16,796 BTC for $175 million; 38,250 held) are unchanged and match the 8-K.
as of 2020-12-04
The Dec 4, 2020 purchase-history row carried a running average purchase price of $13,832.997 in the page’s data (served in the page’s HTML; not displayed). No filing states it: it is the plain mean of the Aug 10, Sep 14 and Dec 4 rows’ per-purchase prices ($11,652.84, $10,419.15 and $19,427), not an average cost of the bitcoin held. The row’s source, the 8-K filed December 4, 2020, states that the company held approximately 40,824 bitcoins acquired at an aggregate purchase price of $475.0 million, and states no average for those holdings. The row now carries no running average. Its displayed figures (2,574 BTC for $50.0 million at about $19,427 each; 40,824 held) are unchanged and match the 8-K.
as of 2020-08-10
The Aug 10, 2020 purchase-history row carried a running average purchase price of $11,652.84 in the page’s data (served in the page’s HTML; not displayed). No filing states it: it is the row’s $250 million cost divided by its 21,454 bitcoins. The row’s source, the 8-K filed August 11, 2020, and the press release attached to it state that the company purchased 21,454 bitcoins at an aggregate purchase price of $250 million, and state no average. The row now carries no running average. Its displayed BTC acquired, cost and holdings (21,454 BTC for $250 million; 21,454 held) are unchanged and match the 8-K.
$2,465,000,000 $2,460,000,000 as of 2025-07-29
The Jul 29, 2025 purchase-history row showed 21,021 BTC bought for $2,465.0 million. Its source, Exhibit 99.1 to the 8-K filed July 29, 2025, states the 21,021 bitcoins and an average purchase price of approximately $117,256, but no cost. The 8-K filed August 4, 2025 states the same purchase (July 28 to August 3, 2025: 21,021 BTC for $2.46 billion at $117,256). The row now shows $2,460.0 million, the 8-K’s $2.46 billion at the precision it states, and cites that 8-K for the cost. One figure computed from stated purchases changes: Q3 2025’s average purchase price in the quarterly table, from $115,962.63 to $115,845.55.
46,076 46,080 as of 2025-07-29
The Jul 29, 2025 purchase-history row carried a total cost of the holdings of $46,076 million in the page’s data (served in the page’s HTML; not displayed). Its source, Exhibit 99.1 to the 8-K filed July 29, 2025, states approximately $46.8 billion for the 628,791 bitcoins held. The 8-K filed August 4, 2025 states $46.08 billion and an average purchase price of $73,277 for the same 628,791 bitcoins as of August 3, 2025; 628,791 bitcoins at $73,277 reconcile with $46.08 billion, while 628,791 at the exhibit’s $73,227 do not reconcile with $46.8 billion. The row now carries $46,080 million, the 8-K’s $46.08 billion at the precision it states, and cites that 8-K for it and for the $73,277 average cost of the holdings it already carried.
as of 2020-08-10
The Aug 10, 2020 purchase-history row showed an average price of $11,652.84 per bitcoin. No filing states it: it is the row’s $250 million cost divided by its 21,454 bitcoins. The 8-K filed August 11, 2020 and the press release attached to it state that the company purchased 21,454 bitcoins at an aggregate purchase price of $250 million, and state no average. The row now shows no average price. Its BTC acquired, cost and holdings (21,454 BTC for $250 million; 21,454 held) are unchanged and match the 8-K.
as of 2020-09-14
The Sep 14, 2020 purchase-history row showed an average price of $10,419.15 per bitcoin. No filing states it: it is the row’s $175 million cost divided by its 16,796 bitcoins. The 8-K filed September 15, 2020 states that the company acquired 16,796 additional bitcoins at an aggregate purchase price of $175 million and held 38,250 bitcoins acquired at an aggregate purchase price of $425 million, and states no average. The row now shows no average price. Its BTC acquired, cost and holdings (16,796 BTC for $175 million; 38,250 held) are unchanged and match the 8-K.
$5,000,000 $5,300,000 as of 2023-11-01
The Nov 1, 2023 purchase-history row showed 155 BTC bought for $5.0 million and cited no source. The 10-Q filed November 1, 2023 states that since September 30, 2023 the company purchased approximately 155 bitcoins for $5.3 million, or approximately $34,495 per bitcoin, and that as of October 31, 2023 it held approximately 158,400 bitcoins acquired at an average purchase price of approximately $29,586. The row now shows $5.3 million and cites that 10-Q; its BTC acquired, average price, holdings and average cost of the holdings are unchanged and match it. One figure computed from stated purchases changes: Q4 2023’s average purchase price in the quarterly table, from $39,281.67 to $39,291.38.
105,084 BTC 105,085 BTC as of 2021-06-21
The Jun 21, 2021 purchase-history row showed total holdings of 105,084 BTC, the figure Strategy’s purchase page lists. No filing or Strategy announcement states 105,084. Strategy’s press release of June 21, 2021 states “As of June 21, 2021, MicroStrategy holds an aggregate of approximately 105,085 bitcoins”, the same as-of date as the row, and the 10-Q filed July 29, 2021 also states 105,085, held at June 30, 2021. The row now shows 105,085 as of Jun 21, 2021 and cites the press release, labelled “Issuer announcement — not filed”. No 8-K was filed for this purchase: SEC staff said so in a comment letter of Oct 7, 2021, and Strategy’s reply of Oct 22, 2021 describes the purchase of approximately 13,005 bitcoins in June 2021. The row had linked that 10-Q, which states neither the 13,005 BTC nor a June 21 total, under an “8-K” label. In the quarterly table, Q2 2021 quarter-end holdings change from 105,084 to 105,085 and the Q3 2021 gain from 8,958 to 8,957 BTC, the figure the 8-K filed Sep 13, 2021 states for that quarter to date; the growth rates computed from them move by less than 0.01 percentage points.
Strategy press release, 2021-06-21; SEC Form 10-Q filed 2021-07-29
$1,023,000,000 $1,026,000,000 as of 2021-02-24
The Feb 19, 2021 purchase-history row showed a cost of $1,023 million for its 19,452 BTC, the figure Strategy’s purchase page lists. No filing or Strategy announcement states it. Strategy’s press release of February 24, 2021 states approximately 19,452 bitcoins bought “for approximately $1.026 billion in cash at an average price of approximately $52,765 per bitcoin” and approximately 90,531 held “As of February 24, 2021”; SEC staff’s comment letter of Oct 7, 2021 and Strategy’s reply of Oct 22, 2021 also give $1.026 billion. The row now shows $1,026 million and holdings as of Feb 24, 2021, and cites the press release, labelled “Issuer announcement — not filed” (the same SEC letter notes that no 8-K was filed for this purchase). Strategy’s page lists the purchase on Feb 19, 2021 and links the 8-K filed that day, which reports the closing of the convertible notes offering whose proceeds funded it and states none of these figures; the row’s note says so. Its chart point moves from Feb 19, 2021 (“as listed”) to Feb 24, 2021 (“as of”). In the quarterly table, Q1 2021’s average purchase price changes from $51,927.50 to $52,071.35.
as of 2024-04-26
The Apr 29, 2024 purchase-history row showed +155 BTC bought for $10.0 million at $63,397, the figures Strategy’s purchase page lists. No filing or Strategy announcement states them. The 8-K filed that day (the first-quarter 2024 earnings release, Exhibit 99.1) states 214,400 BTC held as of April 26, 2024 and no purchase amount for the row. The 10-Q filed May 1, 2024 states approximately 122 BTC bought from March 31 through April 26, 2024 for $7.8 million (about $63,548 each), a different window from this row’s, so it is not substituted. The row now shows no BTC acquired, cost or average price, keeps the 214,400 total, now as of Apr 26, 2024, and cites the 8-K on SEC EDGAR. With no stated amount, the row also leaves the Bitcoin Treasury Tracker’s disclosed-purchase list. Two figures computed from stated purchases change: Q2 2024’s average purchase price in the quarterly table, from $65,861.33 to $65,878.80, and the lifetime monthly average, from 11,554 to 11,552 BTC a month.
$67,455 $67,483
The Aug 1, 2024 purchase-history row showed an average price of $67,455 for its +169 BTC ($11.4 million), the figure Strategy’s purchase page lists, and cited the 8-K filed that day, which states 226,500 BTC held as of July 31, 2024 but no purchase amount. The 10-Q filed August 6, 2024 states: “Since June 30, 2024 through August 5, 2024, the Company has purchased approximately 169 bitcoins for $11.4 million, or approximately $67,483 per bitcoin.” The row now shows $67,483, cites the 10-Q for the BTC acquired, cost and average price and the 8-K (on SEC EDGAR) for the total, now as of Jul 31, 2024, and gives the 10-Q’s period as written, June 30 – August 5, 2024.
$15,698.498 $15,964 as of 2020-12-21
The Dec 21, 2020 purchase-history row carried a running average purchase price of $15,698.498 in the page’s data (served in the page’s HTML; not displayed). Strategy’s press release of December 21, 2020, the row’s only source, states that the approximately 70,470 bitcoins held as of that day were acquired “at an aggregate purchase price of approximately $1.125 billion and an average purchase price of approximately $15,964 per bitcoin”. The row now carries $15,964. The row also linked that release under an “8-K” label; no 8-K was filed for this purchase (EDGAR lists no Strategy filing from December 14 to December 29, 2020), so it is now labelled “Issuer announcement — not filed” and shows holdings as of Dec 21, 2020, as the release states. Its displayed figures (29,646 BTC for $650.0 million at $21,925; 70,470 held) are unchanged and match the release.
121 SEC filings 118 SEC filings
The purchase-history caption, its Markdown heading and the JSON export’s filingCount counted three rows disclosed only by Strategy press releases (Dec 21, 2020; Feb 24, 2021; Jun 21, 2021) as SEC filings. A press release is not a filing, so the count of SEC filings is now 118 and the caption reads “118 SEC filings and 3 issuer announcements”; the JSON export adds announcementCount.
June 30, 2026 July 5, 2026
The Jul 6, 2026 purchase-history record (a sale of approximately 2,225 BTC, holdings 843,775) carried a holdings as-of date of June 30, 2026, the date of the filing’s first table. Its own table reads “During Period July 1, 2026 to July 5, 2026” and “As of July 5, 2026”. The record now carries July 5, 2026; its figures are unchanged.
Until Oct 16, 2026 the tool’s JSON export gave eight older purchase-history rows a filingDate equal to the date Strategy’s purchase page lists for them; #442 then withdrew it. Checked against SEC EDGAR, five of the eight have a filing on the listed date that states the row’s holdings total, and now carry that filing date: Aug 1, 2023 (152,800 BTC; 10-Q 0000950170-23-036448), Nov 1, 2023 (158,400; 10-Q 0000950170-23-057418), Feb 6, 2024 (190,000; 8-K 0000950170-24-011709), Apr 29, 2024 (214,400; 8-K 0000950170-24-049829) and Aug 1, 2024 (226,500; 8-K 0000950170-24-089243). No SEC filing states the other three rows’ figures, so they carry no filing date and are noted as listed by Strategy: Dec 21, 2020 (29,646 BTC; 70,470 held); Feb 19, 2021 (19,452; 90,531), whose listed date matches the 8-K Strategy’s page cites (0001193125-21-048555), which announces the closing of a notes offering and does not state these figures; and Jun 21, 2021 (13,005; 105,084), for which the cited 10-Q of Jul 29, 2021 states 105,085 held at Jun 30. For the five rows with a filing, Strategy’s listed date matches the EDGAR filing date exactly. The other three (Dec 21, 2020; Feb 19, 2021; Jun 21, 2021) have no SEC filing that states their figures, so they have no filing date to compare.
Strategy purchase history (listed dates); SEC EDGAR filings named in the entry
5,050 BTC 8,957 BTC as of 2021-09-12
The Sep 13, 2021 purchase-history entry showed +5,050 BTC for $242.9 million at $48,099, figures the cited 8-K does not state: they were the filing’s quarter-to-date 8,957 BTC (and $419.9 million) less the 3,907 BTC (and $177.0 million) announced Aug 24, 2021. The entry now shows the filing’s own figures — approximately 8,957 BTC for approximately $419.9 million at approximately $46,875, during the period July 1 – September 12, 2021 — marked as including the Aug 24 entry, so totals count that window once. Holdings of approximately 114,042 BTC as of September 12, 2021 are unchanged.
as of 2022-12-27
The Dec 28, 2022 purchase-history entry showed one +2,501 BTC purchase for $44.6 million at $17,847, netting transactions the cited 8-K states separately. The 8-K reports approximately 2,395 BTC acquired during the period November 1 – December 21, 2022 (approximately $42.8 million at $17,871), approximately 704 BTC sold on December 22, 2022 (cash proceeds of approximately $11.8 million at $16,776), and approximately 810 BTC acquired on December 24, 2022 (approximately $13.6 million at $16,845). The history now lists those three transactions, the sale as a sale. Holdings of approximately 132,500 BTC are unchanged; their as-of date is corrected to December 27, 2022, as the filing states (previously recorded as December 21). Figures the tool derives from the history move with it: lifetime gross BTC purchased rises by 704 (the sale is no longer netted out of a purchase), lifting the lifetime monthly pace by about 10 BTC a month, and the 2022 Q4 average purchase price changes from $17,833 to $17,598.
123 SEC filings 121 SEC filings
The purchase-history caption and its Markdown heading counted table rows as SEC 8-K filings. Two 8-Ks each report two periods in separate tables — the one filed January 5, 2026 (Dec 29–31, 2025 and Jan 1–4, 2026) and the one filed July 6, 2026 (two periods around the June 30, 2026 quarter end) — so 123 rows were labelled “123 SEC 8-K filings” when they came from 121 filings. The caption now counts distinct filings, and the JSON export carries filingCount beside the row count.
June 30, 2024 September 19, 2024
The Sep 20, 2024 purchase-history record carried a holdings as-of date (filingAsOf in the tool’s JSON export) of June 30, 2024, taken from a convertible-notes sentence earlier in the 8-K. The filing’s holdings sentence reads “As of September 19, 2024, MicroStrategy, together with its subsidiaries, held an aggregate of approximately 252,220 bitcoins”. The record now carries September 19, 2024; its figures are unchanged.
