A rare arbitrage signal just flashed across crypto-equities: Japan’s Metaplanet is now trading below the value of the Bitcoin it holds. When a treasury stock’s market value dips under its coin stack, the market is pricing in debt risk, dilution, or operational drag—and giving traders a live test of the “Bitcoin at a discount” trade.

What happened: mNAV dips below 1.0

Metaplanet’s market-to-Bitcoin NAV (mNAV) slipped to 0.99—its first sub-1.0 print since starting its accumulation strategy. The firm holds 30,823 BTC (about $3.5B) while shares have fallen 75% from 1,895 yen to 482 yen. mNAV has dropped more than seven points since mid-June. The company paused new BTC buys for two weeks after last adding 5,268 BTC on September 30.

Why this matters to traders

An mNAV below 1.0 means the stock offers BTC exposure at a discount, but with corporate risks attached. The dispersion is widening: roughly 15% of digital-asset treasury firms now trade below 1.0x mNAV (e.g., KindlyMD at 0.959), while others still command premiums (e.g., Strategy at 1.48 with 640,250 BTC). This divergence creates opportunities for convergence trades—and traps if balance-sheet risks intensify.

How to trade the discount (practical playbook)

• Calculate mNAV fast: Enterprise Value = Market Cap + Total Debt + Preferred – Cash. BTC NAV = BTC holdings (minus encumbrances). mNAV = EV / BTC NAV. Sub-1.0 suggests discount.
• Demand catalysts: Look for debt refinancing, buyback authorizations, dilution clarity, auditor updates, resumed accumulation, or governance changes that can close the gap.
• Structure exposure: Long the discounted equity and hedge BTC beta (via futures/options) to target spread convergence rather than coin direction. Alternatively, pair long-discount with short-premium peer.
• Be price- and time-disciplined: Set mNAV alert thresholds (e.g., 0.95/1.05) and predefine exit on catalyst delivery or spread closure.

Risk checklist before you deploy

• Leverage/dilution: Convertible notes, at-the-market offerings, or preferred stacks can keep the discount persistent.
• Operating burn: Cash burn and non-BTC businesses may erode equity value even if BTC rises.
• Liquidity/halts: Venue liquidity, daily turnover, and potential trading halts in local markets.
• NAV timing: Delayed or stale BTC reporting; verify holdings and liabilities cadence.
• Macro/BTC path: A BTC drawdown can deepen the discount; hedge accordingly.
• FX/regulatory: Yen/USD swings and jurisdiction-specific policy risk.

Context: the treasury trade is cooling—temporarily?

Analysts frame this as a cooling or even a bubble “pop” in Bitcoin-treasury names. Yet others argue the market still misprices the model and discounts could turn into persistent premiums as understanding matures. Adoption hasn’t stopped—multiple U.S. states are exploring Bitcoin reserves—but public equity valuations show investors now require proof of value beyond simple coin accumulation.

Actionable takeaway

Treat sub-1.0 mNAVs as setups, not freebies: wait for a balance-sheet catalyst, structure with a BTC hedge, and manage the trade to the spread—not the coin. The best entries appear when a concrete de-risking step is announced and liquidity spikes.
