Metaplanet Ranks as the Fourth Largest Bitcoin Holder Among Corporations.

The Japanese investment firm Metaplanet has purchased an additional 5,268 Bitcoin, approximately valued at $600 million based on current market prices.

Metaplanet announced on Wednesday that this latest acquisition has increased its total Bitcoin (BTC) holdings to 30,823 BTC. This significant move has propelled the Tokyo-listed company to the fourth position among corporate Bitcoin holders, surpassing the Bitcoin Standard Treasury Company, according to data from BitcoinTreasuries.NET.

This latest purchase was executed at an average price of 17.39 million Japanese yen (around $116,000), totaling approximately $600 million. Consequently, its overall holdings have soared to $3.6 billion, with an average acquisition price of around $108,000 per coin.

According to data from BitcoinTreasuries.NET, the company’s Bitcoin strategy has already yielded an unrealized profit exceeding 7.5%.

Metaplanet’s Bitcoin Yield surged to 300% by late 2024

Metaplanet began accumulating Bitcoin for its balance sheet in April 2024, growing at a pace faster than nearly every other corporate Bitcoin holder.

Documentation indicates that its BTC Yield reached as high as 309.8% in late 2024 before stabilizing at 33% this year. BTC Yield reflects the percentage change in the ratio of total Bitcoin holdings to fully diluted shares, offering investors enhanced insights into Bitcoin backing for each share.

A 309% BTC Yield signifies that Metaplanet’s speed of Bitcoin accumulation significantly outpaced any dilution of its shares. At that time, each share possessed more than three times the Bitcoin exposure than at inception.

Despite the rapid accumulation rate in late 2024, the metric decreased to 33% in 2025, indicating that while the company continues to acquire Bitcoin, the growth in per-share exposure has moderated.
