Metaplanet Just Flipped Coinbase in Bitcoin Holdings, and It’s Only Getting Started

Japanese investment firm Metaplanet (JP:3350) now owns 10,000 Bitcoin. That’s more than Coinbase (COIN). That’s more than Tesla. And it might just be the beginning.

The company announced on Monday it had scooped up another 1,112 BTC for 16.88 billion yen (roughly $117 million), putting its total holdings past the 10K mark. According to Bitbo data, that leapfrogs Coinbase’s stash of 9,267 BTC, making Metaplanet the seventh-largest corporate holder of Bitcoin in the world.

But it’s not stopping there.

210,000 BTC by 2027? That’s the Plan

Metaplanet isn’t playing small-ball. In the same announcement, the firm revealed it has approved the issuance of $210 million in zero-interest bonds—money that’s going straight into more Bitcoin.

That capital injection is just phase two. The endgame? A staggering 210,000 BTC target by the end of 2027. That would make Metaplanet one of the most influential corporate whales in crypto—possibly rivaling even MicroStrategy if it pulls it off.

So far, the firm’s cost basis sits at around $96,400 per coin. That means the company has already bought into Bitcoin at prices near the current range and is still hungry for more—indicating a deep conviction in BTC’s long-term upside.

Metaplanet Stock Soars on Bitcoin-Buying Spree

Metaplanet’s stock surged over 22% on the Tokyo Stock Exchange, closing the day at 1,860 yen. Year-to-date, the stock has exploded over 417%, largely on the back of its aggressive Bitcoin strategy.

The company’s rise mirrors a growing narrative: traditional businesses embracing Bitcoin not just as a hedge, but as a balance sheet backbone.

Bitcoin’s Institutional Game Is on a New Level

Metaplanet’s move adds another chapter to 2025’s Bitcoin institutionalization story.

Despite Bitcoin briefly plunging from $110K to $103K amid geopolitical tensions, ETF inflows didn’t stop. In fact, more than $1.3 billion flooded into spot Bitcoin ETFs last week alone, according to industry data.

Even Strategy’s (MSTR) Michael Saylor said he was buying more BTC. This is proof that long-term players aren’t fazed by short-term volatility.

Meanwhile, Bitwise CEO Hunter Horsley said Bitcoin could eventually rival the $30 trillion U.S. Treasuries market. That’s not just moon talk, it’s a sign that crypto is being viewed in the same breath as the most liquid, stable financial products in the world.

Metaplanet’s 10K milestone isn’t just about bragging rights over Coinbase. It’s about the race many firms have gotten into to acquire Bitcoin. They’re issuing bonds, reworking treasuries, and treating Bitcoin like a once-in-a-generation asset.

Whether or not Metaplanet actually hits 210,000 BTC is almost beside the point. What matters is that companies are now treating Bitcoin as strategic infrastructure, and not just a speculative bet. And every time another boardroom signs off on a multi-million dollar BTC buy, the game shifts a little more in Bitcoin’s favor.
