Metaplanet Buys Bitcoin Worth $451M as Market Pressure Grows

Japanese firm Metaplanet Inc., has once again proven its deep commitment to Bitcoin (BTC). The Tokyo-listed firm recently made a fresh Bitcoin purchase worth more than $451 million. 

This came at a time when crypto markets face renewed selling pressure and its own stock price has slipped. 

Metaplanet Adds 4,279 BTC Amid Market Weakness

On December 30, Metaplanet said it bought 4,279 more Bitcoin in the fourth quarter of 2025. The purchase was worth over $451 million. The company paid an average price of $105,412 for each Bitcoin, according to its official report.

The announcement came after Metaplanet’s stock price dropped almost 8% to 405 JPY, as Bitcoin prices were under pressure. Even with this short-term decline, the company went ahead with the purchase, showing strong belief in Bitcoin over the long term.

After this latest buy, Metaplanet now holds 35,102 Bitcoin, worth more than $3 billion at current prices. Metaplanet now holds the position of the fourth-largest Bitcoin treasury worldwide. 

However, the recent drop in Bitcoin prices has pushed the company into an unrealized loss of nearly $520.34 million. This shift also caused Metaplanet’s modified net asset value (mNAV) to fall sharply from 1.17 to 1.03 in just one day.

Metaplanet Strengthens Capital Base

Alongside its Bitcoin purchase, Metaplanet completed payment for the issuance of 23.61 million MERCURY Class B preferred shares. This move strengthens the company’s capital base and supports its continued Bitcoin accumulation plan.

The firm also expects strong performance from its Bitcoin Income business. For Q4 2025, Metaplanet expects operating revenue of JPY 4.242 billion. This shows the company is working to earn income beyond just holding assets.

Earlier reports confirmed that Metaplanet shareholders approved all five management proposals aimed at expanding Bitcoin holdings. These decisions clear the path for the company’s ambitious goal of accumulating 100,000 BTC by the end of 2026.

Metaplanet Shares Slide as Bitcoin Weakens

Metaplanet shares fell 7.95% to 405 JPY as Bitcoin dropped below $87,000. Despite this, the stock is still up nearly 2% this month, supported by institutional interest.

In the U.S., Metaplanet’s MTPLF shares fell 4.25% to $2.70 but are still up 16% this year. MPJPY shares also dropped 4.20% to $2.74, with losses now near 6% since their recent debut.

At the time of writing, Bitcoin itself dropped more than 2% to trade around $87,301, according to CoinMarketCap data. Trading volume jumped by 38%, showing heightened market activity.

Data from CoinGlass showed a cautious mood in the derivatives market. Bitcoin futures open interest fell over 5% to $57.41 billion, with sharp drops on CME and Binance, showing traders are taking less risk.
