The debt clock ticking inside corporate Bitcoin treasuries could force billions back onto the market

Summary

Corporate Bitcoin treasuries sit behind layered claims from creditors, preferred holders, lenders, and operating needs, so maturities, redemption dates, and dividend obligations can force Bitcoin sales even without a change in long-term outlook. VanEck’s Matthew Sigel mapped these capital structures and highlighted examples such as Bitdeer, which emptied its treasury to fund an AI pivot. Strategy is the key case: it held 843,738 BTC, plus billions in convertible notes and preferred stock, and its STRC preferred came under pressure as Bitcoin fell. Strategy sold 32 BTC to fund STRC payouts, paused new share issuance, then raised STRC dividends and authorized Bitcoin sales to support reserves, preferred payments, interest, and buybacks. MARA also sold Bitcoin to retire convertibles, and KULR pledged BTC against a loan. The model works best when Bitcoin rises, shares trade above net asset value, and capital markets stay open. If those conditions weaken, calendar-driven Bitcoin selling could rise sharply across public companies, especially with maturities concentrated in 2027–2028.
