Metaplanet Expands Bitcoin Reserves to Over 18,000 After Latest 518 BTC Buy

Key Takeaways:

• Metaplanet boosts its Bitcoin holdings to 18,113 BTC with a fresh $1.85B buy.
• The company aims to stack up 210,000 BTC before 2027.
• Economic turmoil and fiat decline fears drive corporate Bitcoin purchases.

On August 12, Metaplanet expanded its Bitcoin portfolio with the purchase of 518 BTC, valued at about $1.85 billion (9.086 billion yen). This latest acquisition increased the company’s total Bitcoin holdings to 18,113 BTC, with an impressive BTC Yield of 468.1% YTD 2025. 

Metaplanet Sets Sights on Owning 1% of All Bitcoin Supply by the End of 2027

Since its pivot from hotel management to digital assets in 2024 under CEO Simon Gerovich, Metaplanet has gone from a niche Japanese investment firm to one of Asia’s most aggressive corporate Bitcoin holders.

Metaplanet has acquired 518 BTC for ~$61.4 million at ~$118,519 per bitcoin and has achieved BTC Yield of 468.1% YTD 2025. As of 8/12/2025, we hold 18,113 $BTC acquired for ~$1.85 billion at ~$101,911 per bitcoin. $MTPLF pic.twitter.com/Gm2bYBgYF0

In June, the company bought 1,112 Bitcoins worth about $117.2 million. That single purchase lifted its Bitcoin reserves to 10,000 BTC, a milestone that underscored its determination to keep stacking.

A string of new acquisitions in July quickly pushed Metaplanet’s Bitcoin holdings beyond those of Coinbase.

According to data from Bitcointreasuries.net, the Japanese firm now ranks among the top seven corporate holders of Bitcoin worldwide, a position few would have predicted just two years ago.

Driving this surge is the company’s “555 Million Plan,” a long-term strategy to acquire 210,000 BTC, around 1% of the total Bitcoin supply, by the end of 2027. 

This is a massive leap from its “21 Million Plan,” which aimed at 21,000 BTC by 2026.

However, the scale of financing this objective requires creativity. Metaplanet has leaned heavily on unconventional methods like zero-interest bonds, moving-strike warrants, and perpetual preferred stock issuances.

On August 1, the firm filed for a shelf registration to raise 555 billion Japanese yen (about $3.74 billion) through perpetual preferred shares.

It also sought approval to increase its authorized share count to 2.72 billion and introduce two classes of perpetual preferred shares with different risk and conversion terms.  

Perpetual preferred shares are a type of stock that pays fixed dividends but has no maturity date, meaning the company never has to repay the principal. 

Metaplanet's latest purchase of 518 Bitcoins shows the plan is already in motion.

Corporate Bet on Bitcoin Gains and Fiat Currency Decline

Metaplanet’s aggressive buying spree is anchored in a core belief. Bitcoin will keep rising in value over the long term, while fiat currencies like the Japanese yen and the U.S. dollar will lose purchasing power. 

This view is shared among other corporations. 

In late July, Quantum Solutions, a Japanese AI company, announced plans to borrow funds to buy up to $10 million in Bitcoin. Over the next year, it aims to build a Bitcoin reserve of 3,000 BTC, citing fears over the yen’s decline and the erosion of global fiat value.

In the U.S., GameStop’s CEO Ryan Cohen described the retailer’s $513 million Bitcoin purchase as a calculated hedge against inflation. He stressed it was about protecting the company’s value, not chasing crypto hype.

Michael Saylor’s Strategy remains the standard-bearer. Between July 28 and August 3, it bought 21,021 Bitcoins worth about $2.46 billion. On August 11, it added another 155 BTC, pushing its total Bitcoin reserves to an unprecedented 628,946 BTC, valued at nearly $75 billion.

For these firms, the strategy is clear. In a world where central banks can print unlimited currency, an asset with a fixed supply of 21 million coins is uniquely valuable. 

Billionaire investors like Ray Dalio argue that companies and investors should dedicate at least 15% of their portfolios to Bitcoin as a hedge. 

If inflation persists and fiat currencies keep sliding, this wave of corporate accumulation may one day be seen as one of the smartest plays of the decade.
