Bitcoin treasury companies: capital structure, not holdings, decides who owns the bitcoin

A “bitcoin treasury company” is not really an operating business; it is a machine for converting capital-markets access into bitcoin per share. In 2026 the three leading examples — Strategy (Nasdaq: MSTR), Strive (Nasdaq: ASST) and Metaplanet (TSE: 3350) — all flipped from a premium to a discount to the value of their bitcoin, and the model only compounds value above parity. Once you account for the debt and preferred stock that rank ahead of common shareholders, the apparent hierarchy inverts: the largest, most sophisticated balance sheet is not the safest, and the most-constrained company leaves common holders the cleanest claim. Figures are point-in-time as of 22 June 2026 and move weekly.

• The sector-wide premium has gone. By mid-2026 Strategy (847,363 BTC), Metaplanet (40,177 BTC) and Strive (~19,900 BTC) all trade below the value of their bitcoin, and all three sit beneath their average cost. The bull-market flywheel only spins above ~1.0× mNAV.
• Differences run on two distinct axes. Strategic: Strategy and Strive are both US-listed with the same toolkit but opposite choices — four funding rails versus one. Jurisdictional: Metaplanet operates in Japan, where the rules forbid the US preferred-stock playbook and a NISA tax shelter creates retail demand no US issuer can replicate.
• After senior claims, common owns far less bitcoin than the headline implies. “Claims drag” is ~45% at Strive, ~38% at Strategy and ~16% at Metaplanet — so preferred stock, not size, drives the drag, and the company barred from preferred (Metaplanet) gives common the cleanest claim (~84% of the bitcoin).
• Strategy's credit rail is visibly stressed. Its variable-rate preferred STRC de-pegged to ~$89 (≈11% below par) on 18 June 2026, new issuance paused, and the company made its first bitcoin sale since 2022 to fund preferred dividends.
• The decisive question for an allocator is no longer “how much bitcoin?” but “what sits in front of the common shareholder?” Scale and financial sophistication are not the same as resilience.

Investors and corporate-development leaders evaluating bitcoin-treasury equities should:

• Read mNAV and claims drag together, never holdings alone — ask what debt and preferred rank ahead of common before crediting a company with its full bitcoin reserve.
• Treat the preferred-dividend obligation (on the order of US$1.5–1.7bn/yr at Strategy) as a fixed cash liability that bites hardest precisely when markets are weakest.
• Separate strategic from jurisdictional differences: the first are changeable choices, the second are structural. Do not benchmark Metaplanet as a smaller Strategy — it is competing for a different (tax-sheltered, domestic-retail) pool of capital.
• Be willing not to pay up for scale. In a discount regime the smaller, more constrained issuer can offer the cleaner economic claim on the underlying asset.
