Metaplanet Tops MARA as Third Bitcoin Treasury

Metaplanet's Bitcoin treasury strategy just broke into the global top three. The Tokyo-listed firm disclosed Wednesday that it added 5,075 BTC during Q1 2026, spending roughly $405 million at an average price of about $79,900 per coin — a buying pace that has pushed the company past MARA Holdings and into third place among publicly traded corporate holders worldwide.

How Metaplanet Climbed the Corporate Bitcoin Rankings

The jump to third didn't come purely from aggressive buying. Timing and a rival's retreat helped. MARA Holdings sold roughly 15,000 BTC in March for $1.1 billion to repurchase a portion of its convertible notes at a discount — a balance sheet move that slashed the miner's stack to approximately 38,700 BTC. That created the opening Metaplanet needed.

Metaplanet's Q1 purchase brings its cumulative holdings to 40,177 BTC, acquired for a total outlay of around $4.18 billion. The average cost basis across that entire stack sits at $104,106 per coin — well above the $79,900 average price the firm paid during the first quarter, which implies the company paid significantly more per coin in prior quarters. That's a detail worth watching as Bitcoin prices fluctuate.

The firm now sits behind only Strategy — the original Bitcoin treasury company, which holds more than 762,099 BTC — and Twenty One Capital, which holds 43,514 BTC. The gap between Metaplanet and Twenty One Capital is less than 3,400 BTC. If the Tokyo firm keeps buying at Q1's pace, that gap closes fast.

What Does 'BTC Yield' Actually Mean?

Metaplanet reported a BTC yield of 2.8% year-to-date — a figure that sounds like interest income but isn't. The metric is self-defined: it tracks the growth in Bitcoin holdings per diluted share, essentially measuring how much the company is growing its per-share BTC exposure over time. It says nothing about whether those coins have appreciated in price.

Strategy uses the exact same metric. It's a capital efficiency measure dressed up in yield language — and critics would argue it's better suited to a marketing deck than a balance sheet. Still, for investors who bought into the treasury thesis, it's a useful way to track dilution against accumulation. If the share count is rising faster than BTC holdings, yield goes negative. At 2.8% YTD, Metaplanet is at least holding the line.

Twenty One Capital, for its part, used to push its own version called Bitcoin Per Share (BPS). CEO Jack Mallers said at the start of the year the company had quietly dropped that metric. Make of that what you will.

The 555 Million Plan: Ambitious or Unrealistic?

Third place is not the destination. Metaplanet has a published roadmap — its 555 Million Plan — that calls for holding 100,000 BTC by the end of 2026 and 210,000 BTC by the close of 2027. At current prices, hitting that 2027 target means sourcing roughly $10 billion in capital from somewhere.

The funding mechanics so far: the company raised $137 million in January through a share and warrant sale, with another $276 million in potential follow-on funding baked into the same deal. That's $413 million in runway — enough to buy at Q1's pace for about one more quarter. To reach six figures of BTC, Metaplanet needs a lot more capital raises, and each one likely comes with dilution that pressures that BTC yield metric.

The stock tells part of the story. Metaplanet trades on the Tokyo Stock Exchange under ticker 3550 and over-the-counter as MTPLF. On Wednesday it closed at $1.89 (302 yen) — down roughly 2% on the day. That's a long way from the near-1,930 yen peak the stock hit in June 2025. Shares have essentially given back a year of gains while the BTC stack has grown. The market, it seems, isn't fully pricing in the accumulation story yet — or it's pricing in the dilution risk instead.

Does Buying Bitcoin at $104K Average Make Sense Now?

Here's the tension nobody talks about loudly: Metaplanet's blended cost basis of $104,106 per BTC is above where Bitcoin currently trades. The firm bought heavily at higher prices, then picked up more at $79,900 in Q1 — a discount that lowers the stack-level average only marginally. If Bitcoin doesn't reclaim six figures soon, every quarterly report becomes harder to defend to shareholders.

That's not unique to Metaplanet. Strategy faces the same arithmetic on a much larger scale. But Strategy has the balance sheet muscle and brand recognition to weather prolonged downturns. A Tokyo-listed mid-cap with a comparatively thin equity base operates with less cushion. The 555 Million Plan is bold by any measure. Bold plans need price cooperation to pay off.

What Metaplanet has going for it: Bitcoin treasury plays have attracted a new class of investor — people who want BTC exposure through traditional brokerage accounts without touching a crypto exchange. As long as that demand exists, the model has runway. The question is whether the capital raises can keep pace with the ambition without wrecking the per-share story.
