Metaplanet Becomes Third-Largest Bitcoin Treasury After Buying 5,075 BTC in Q1

Metaplanet has moved into the top tier of public company Bitcoin holders after a major Q1 buying spree. The Japanese firm acquired 5,075 BTC for about $405.48 million at an average price of roughly $79,898 per Bitcoin, lifting its total treasury to 40,177 BTC and pushing it into third place globally among listed corporate holders.

The update came directly from CEO Simon Gerovich, who said the company’s BTC Yield reached 2.8% year to date in 2026. As of March 31, 2026, Metaplanet said its full Bitcoin position had been acquired for about $4.18 billion, with an average cost basis of roughly $104,106 per BTC.

This was not a marginal treasury adjustment. Adding 5,075 BTC in one quarter means Metaplanet increased its total holdings by more than 12% in just three months, which is one of the more aggressive corporate Bitcoin accumulation moves seen this year.

That matters because scale changes perception. A company buying a few hundred BTC can still be treated as a niche Bitcoin proxy, but crossing 40,000 BTC puts Metaplanet into a very different category. It is now large enough that every additional purchase changes the global corporate Bitcoin leaderboard in a visible way.

The key Q1 figures are straightforward:

• Q1 2026 purchase: 5,075 BTC

• Q1 spend: $405.48 million

• Average Q1 buy price: $79,898 per BTC

• Total holdings as of March 31: 40,177 BTC

• Total acquisition cost: about $4.18 billion

• Average full-stack cost basis: about $104,106 per BTC

• BTC Yield YTD 2026: 2.8%

The latest purchase moved Metaplanet ahead of MARA Holdings, making it the third-largest publicly listed Bitcoin treasury company. Based on the reporting around the announcement, only Strategy and Twenty One Capital remain ahead of it.

That ranking matters because Metaplanet is now one of the few public companies holding more than 40,000 BTC. Metaplanet is no longer just a Japan-based company buying Bitcoin for branding or investor attention. It has become one of the largest listed corporate vehicles for Bitcoin exposure in the market.

Gerovich framed the update as continued progress, not a one-off trade. That is important, because the market reads treasury language carefully. A tactical buy is one thing, but a company repeatedly publishing acquisition numbers, cost basis data, and internal performance metrics is signaling a longer-term Bitcoin accumulation strategy.

The numbers did not come from market rumor or third-party speculation. They came from company reporting and the CEO’s own public update, which included the size of the purchase, the average entry price, the total holdings, and the year-to-date BTC Yield figure.

In fast Bitcoin markets, even strong long-term conviction does not remove execution risk. Large Bitcoin treasury moves can also increase short-term volatility, which makes slippage in crypto more relevant for traders reacting to sharp price swings.

One of the most useful details in this update is the difference between Metaplanet’s latest quarter purchase price and its full-treasury average cost. The company bought Q1 Bitcoin at about $79,898, while its overall average acquisition cost remains near $104,106. That suggests the firm used lower prices in Q1 to improve the efficiency of its existing treasury base rather than simply adding BTC at any cost.

That does not make the strategy low risk. It just means the company appears to be accumulating with some attention to price efficiency as Bitcoin volatility persists, which is why stop loss in trading still matters for active market participants.

The next question is whether Metaplanet keeps adding at this pace. The gap between Metaplanet and Twenty One Capital is now relatively small, which means another notable BTC purchase could reshape the upper part of the corporate Bitcoin treasury table again.

There is also a broader market signal here. When a non-U.S. public company becomes one of the world’s biggest Bitcoin holders, it strengthens the idea that the corporate Bitcoin treasury trend is no longer concentrated in one region or one type of listed firm. That is one reason this story matters beyond Metaplanet itself.

Even with strong corporate demand in the background, crypto hedging remains relevant for traders who want protection against sharp reversals.

Metaplanet did not just buy more Bitcoin in Q1. It bought enough to change its place in the global corporate rankings. After spending $405.48 million on 5,075 BTC, the company now holds 40,177 BTC and stands as the third-largest public company Bitcoin holder.

The bigger takeaway is that this no longer looks like an experimental treasury move. With Simon Gerovich openly highlighting the company’s growth and BTC Yield, Metaplanet is positioning itself as a serious long-term Bitcoin treasury company, and the market will now be watching whether it stops at third place or keeps climbing.
