Japanese investment firm Metaplanet has injected $5 billion into its U.S. subsidiary, Metaplanet Treasury Corp., as part of its plan to grow its bitcoin (BTC) holdings and expand globally in the digital asset space.
The funds will be used to accelerate the company’s “555 Million Plan” to buy up to 210,000 BTC by the end of 2027—1% of bitcoin’s total supply. Metaplanet has already made good progress, recently increasing its holdings to 11,111 BTC, worth over $1.1 billion.
Metaplanet’s U.S. arm, Metaplanet Treasury Corp, launched in May 2025, and based in Florida, is a key part of the company’s strategy. Florida and Miami in particular have become pro-Bitcoin havens, and digital asset infrastructure is growing.
By entering the U.S. market, the company will benefit from deep capital markets, institutional infrastructure and transparent regulations to buy and manage large amounts of bitcoin.
The company will access both exchange and over-the-counter (OTC) markets for large BTC purchases.
“This U.S. expansion underscores our determination to establish a globally integrated treasury model,” Metaplanet said in a statement.
“The Company believes this approach will drive long-term accretion to shareholder value, enhance treasury yield efficiency, and reinforce our positioning at the forefront of Bitcoin-based capital market innovation.”
The $5 billion will be funded by exercising stock acquisition rights from previously issued convertible securities. The funds will be used exclusively for bitcoin purchases with no change to the use of proceeds as previously disclosed.
The “555 Million Plan” was announced on June 6, 2025 and outlines Metaplanet’s path to becoming one of the world’s largest corporate bitcoin holders. The company will buy 30,000 BTC by the end of 2025, and 210,000 BTC over the next few years.
This is not just a financial move but a strategic one. It’s about building a transparent, efficient and global treasury on bitcoin.
Metaplanet’s stock has gone up over 1,250% in the last 6 months and part of that is due to their aggressive push into bitcoin.
But the recent announcement has caused short-term volatility in the stock. After hitting $15 the U.S.-listed MTPLF, shares dropped to $10.9 and the Tokyo-listed shares dropped 5.38% closing at 1,547 JPY.
Despite the dip, institutional investors are showing strong interest. Citigroup and Capital Group have reportedly bought 3 million shares of Metaplanet this month. Analysts see this as a sign of growing confidence in bitcoin-focused corporate strategies.
Some analysts are worried about the premium in Metaplanet’s stock and say it’s pricing bitcoin at $596,000 to $759,000 per coin—way above current market prices.
This has sparked debate about sustainability and stock dilution but also shows investors want bitcoin exposure through equities.
Metaplanet is part of a growing trend of public companies adding bitcoin to their treasuries.
Over 240 public companies now hold over 832,000 BTC combined, according to BitcoinTreasuries. Companies like Cardone Capital, Nakamoto Holdings and CleanSpark are also increasing their bitcoin reserves.
