SKN | Metaplanet Moves $377 Million in Bitcoin to Coinbase, Raising Selloff Concerns

Key Points:

• Metaplanet transferred 4,800 BTC worth nearly $377 million to Coinbase Prime, adding to a series of large deposits this week.
• The Japanese Bitcoin treasury company has moved a combined 10,270 BTC, worth about $806.3 million, to Coinbase Prime over six days.
• The transfers represent more than 29% of Metaplanet’s reported 35,102-BTC treasury, although the movements alone do not confirm that the company is selling.

Metaplanet has transferred another 4,800 Bitcoin worth nearly $377 million to Coinbase Prime, intensifying speculation that the Japanese Bitcoin treasury company could be preparing to sell a substantial portion of its holdings. The transactions come after several other large transfers this week and highlight growing uncertainty around the willingness of corporate Bitcoin treasuries to maintain aggressive accumulation strategies during a volatile market.

According to Arkham Intelligence data, Metaplanet transferred 4,800 BTC to Coinbase Prime on Monday. The move followed a 2,000-BTC transfer worth about $155.5 million two days earlier, while transfers three days ago totaled 3,331 BTC, valued at nearly $266 million. Another 139 BTC worth approximately $11.1 million was moved six days ago.

Together, the transfers amount to 10,270 BTC worth roughly $806.3 million.

Large transfers fuel Bitcoin sale speculation

Metaplanet remains the fourth-largest corporate Bitcoin holder, with a reported treasury of 35,102 BTC worth approximately $2.75 billion. If the transferred Bitcoin were ultimately sold, the company’s holdings could decline by more than 29%.

However, movement of Bitcoin to an exchange or institutional custody platform does not necessarily establish that a sale has occurred. Coinbase Prime provides institutional trading and custody infrastructure, meaning Metaplanet could potentially use the platform for several purposes, including custody arrangements, financing or future transactions.

The distinction is important for investors. Onchain transfers can provide an early indication of changes in treasury strategy, but they do not by themselves reveal the company’s final intent.

Still, the scale and frequency of the transfers make the activity difficult for the market to ignore. A disposal of more than 10,000 BTC would represent a significant reversal for a company whose investment strategy has been centered on building one of the largest corporate Bitcoin treasuries.

Corporate Bitcoin strategies begin to diverge

Metaplanet’s activity also contrasts with moves from other corporate Bitcoin buyers. French Bitcoin treasury company Capital B recently raised €21 million, or about $24.5 million, through a private share placement to acquire another 270 BTC.

The divergence illustrates how corporate treasury strategies are becoming increasingly differentiated. Some companies continue to view Bitcoin accumulation as a long-term balance-sheet strategy, while others are reassessing exposure as financing conditions, market valuations and liquidity requirements change.

Smaller treasury companies have also recently sold Bitcoin to redirect capital toward other business opportunities, demonstrating that corporate adoption does not necessarily translate into permanent or one-way demand.

What investors should watch next

The key issue for Bitcoin markets will be whether Metaplanet converts the Coinbase deposits into actual sales and, if so, how much of its treasury is ultimately distributed into the market.

A confirmed sale could create additional short-term supply pressure while challenging the assumption that corporate Bitcoin treasuries will consistently absorb market supply. Conversely, if the Bitcoin remains in institutional custody or is used for another financial purpose, the transfers could prove less bearish than initially feared.

For investors, Metaplanet’s next disclosures and wallet movements will therefore be more important than the transfers alone. The episode underscores a broader shift in the corporate Bitcoin market: treasury companies are becoming significant holders, but their capital strategies can also become a source of volatility when large positions move toward institutional trading venues.
