Metaplanet Bitcoin Purchase Achieves Stunning 18,113 BTC

Key PointsMetaplanet Bitcoin Purchase Pushes Holdings to 18,113 BTC

• August 2025 purchase adds 518 BTC to reserves
• The company uses “BTC Yield” as a new performance metric
• Remains the 6th largest public Bitcoin holding firm globally

In a bold August move, Metaplanet Inc. added another 518 Bitcoin to its reserves, pushing its total holdings to 18,113 BTC, valued at around $1.85 billion. The Tokyo-listed company’s aggressive treasury strategy is placing it firmly among the elite group of public firms with massive Bitcoin reserves.

Since embracing Bitcoin as a core business in December 2024, Metaplanet has transformed from a zero-BTC firm to a corporate heavyweight in less than two years.

The latest acquisition, costing about 9.1 billion yen, solidifies its role as one of the most active buyers in the public market. This mirrors a wider trend in the crypto space, where influential figures like Vitalik Buterin and major institutions continue to reshape digital asset strategies.

Metaplanet’s Strategic Bitcoin Expansion

The company’s approach to funding its BTC purchases is as bold as the purchases themselves. Metaplanet relies on capital markets, primarily issuing shares and bonds, to generate the cash needed for its multi-billion-yen buys. This has allowed them to scale rapidly without relying solely on operational cash flow.

Financial records reveal a steep upward curve:

• Start of 2024: 0 BTC

• Mid-2024: 141 BTC

• End of Fiscal 2024: 1,762 BTC

• June 2025: 12,345 BTC

• August 2025: 18,113 BTC

Their rapid climb keeps them in the 6th position among publicly traded Bitcoin holders, just behind Trump Media & Technology Group Corp. With a narrow gap between them, overtaking the 5th spot seems within reach.

Metaplanet’s growth rate is also a signal to markets that it’s aiming for a much larger piece of the corporate Bitcoin pie.

With public statements targeting 100,000 BTC by the end of 2025, the company could leapfrog several competitors in just months if the buying pace continues.

Similar rapid surges have been seen in niche crypto markets, such as the Beeple NFT stunt that recently triggered a massive price spike for digital collectibles.

“BTC Yield” – A New Way to Measure Bitcoin Success

Metaplanet is also pioneering how it measures success. Instead of relying solely on traditional performance indicators, the company introduced “BTC Yield,” a metric tracking the ratio of total Bitcoin holdings to fully diluted shares.

BTC Yield results have been notable:

• Q4 2024: 309.8%

• Q2 2025: 129.4%

• July–August 2025: 26.5%

This metric highlights how each acquisition potentially benefits shareholders by increasing the Bitcoin backing per share. The company’s filings emphasize that this strategy is meant to be “accretive to shareholders,” reinforcing the value of their aggressive accumulation plan.

Analysts point out that this kind of metric could influence how other Bitcoin-heavy public companies report their performance.

By shifting focus toward asset-per-share growth, it reframes corporate treasury management in a Bitcoin-driven economy, something becoming increasingly important as regulatory pressures mount, such as the Ethereum developer detention in Turkey that sparked global debate over crypto freedoms.

Market Position and Competitive Landscape

Despite its rapid growth, Metaplanet still has a way to go before catching the top players. MicroStrategy, the leader by a massive margin, holds 628,946 BTC, valued at roughly $74 billion, thanks to continuous purchases led by Michael Saylor, who just announced another 155 BTC buy worth $18 million.

Following MicroStrategy are other major holders like Marathon Digital Holdings, Tesla, and Block Inc., with Trump Media & Technology Group Corp currently in 5th place. The gap between Trump Media and Metaplanet is small enough that a single large acquisition could shift rankings.

What makes Metaplanet’s rise remarkable is the timeframe. Moving from 141 BTC in mid-2024 to over 18,000 BTC in August 2025 represents a growth rate rarely seen in the corporate Bitcoin landscape. Few companies have matched such a steep accumulation curve, especially outside the U.S.

Market watchers note that this level of accumulation from an Asia-based firm could shift the global geographic balance of large Bitcoin treasuries.

Until now, most of the largest holders have been North American companies, but Metaplanet’s rise could inspire more Asia-Pacific firms to adopt similar treasury strategies.

If this happens, we could see competition in areas like ETF approvals—similar to the BlackRock XRP ETF rejection that recently made headlines—and increased activity in DeFi markets, where Coinbase’s DEX trading is gaining traction.

With its ambitious 100,000 BTC target and innovative performance tracking through BTC Yield, Metaplanet is carving out a unique position in the market.

The coming months will reveal whether its aggressive strategy will not only push it past Trump Media for the 5th spot but also bring it closer to the titans at the top of the Bitcoin leaderboard.
