Net change = the bitcoin the company states it held at September 30, 2026 minus what it stated at June 30, 2026, in BTC.1 The counts are not all on the same basis: most include bitcoin pledged as collateral or loaned out (MARA’s 34,012 includes 19,260 bitcoin loaned or pledged), miners’ counts are mining inventory, Coinbase’s and Block’s are bitcoin held for investment, and Hut 8 is shown without American Bitcoin (its 10-Q: 16,787 consolidated, “comprising approximately 8,360 Bitcoin held by Hut 8 and approximately 8,427 Bitcoin held by American Bitcoin”), which is listed separately.1516 Not shown: Twenty One Capital, GD Culture Group, Gemini Space Station, Silvia and Nakamoto, which had not filed a Q3 Form 10-Q on EDGAR by November 10; CleanSpark, whose September 30 total of 13,530 includes 3,475 bitcoin posted as collateral or as receivable while its June 30 figure excluded the collateral receivable, so there is no like-for-like change; Trump Media, whose 10-Q states bitcoin units in separate lines (4,263.94 as digital assets and 11,385.20 pledged for its option strategy) but no one total at both dates; and companies without a clean count at both dates (Galaxy, Bullish) or with different fiscal quarters (GameStop). Ranks are by net change; ties share a rank. This is a net figure, so a company can have bought and sold within the quarter. Observed facts from filings, not a forecast.
