Bitcoin Treasury Companies’ Share Buyback Programs, data as of 2026-10-19
A buyback program is a board authorization to repurchase up to a set amount of the company’s own shares; it does not oblige the company to buy any. Sizes are in each company’s currency and are not comparable: Hut 8’s cap is a Canadian legal limit, Boyaa’s is a standing mandate to its next annual meeting, and Strategy has two programs for different securities. Repurchase totals come from the latest filing and carry different as-of dates. Companies checked with no common-share program found in their latest quarterly report: Twenty One, MARA, CleanSpark, Riot, Tesla, Gemini, American Bitcoin, GD Culture and Next Technology; Capital B, Smarter Web and H100 were not resolved, so this list is not exhaustive.
Highlights
A company buying back its own shares reduces the number outstanding. For a bitcoin treasury company that is one way to spend capital besides buying more bitcoin, and the programs below were authorized between December 2024 and October 2026. Boyaa Interactive’s standing mandate is up to 10% of its issued shares, passed at its June 18, 2026 annual meeting; 4,796,000 shares had been repurchased by July 10, 2026.11 These entries describe the programs only; they are not recommendations.
