Marathon Sale Reshapes Corporate Bitcoin Rankings

A significant reshuffling has taken place among publicly traded Bitcoin holders, with Twenty One Capital emerging as the second-largest corporate holder of BTC following a significant sale by Marathon Digital Holdings (MARA).

A Major Shift in Public Bitcoin Holdings

The transaction marks a rare moment where one of the sector’s most prominent mining firms materially reduced its BTC reserves, allowing another institution to move up the rankings. According to data from BitcoinTreasuries, Twenty One Capital holds 43,514 BTC in its corporate treasury, valued at over $2.9 billion at the market price as of this writing. 

While MARA has historically pursued an aggressive accumulation strategy, often retaining mined BTC rather than selling, the latest move signals a tactical shift. The company reduced a portion of its holdings, though it has not indicated a full departure from its long-term BTC treasury approach.

As a result, the firm dropped from second to third place among corporate BTC holders. In contrast, the shift elevated Twenty One Capital, reflecting its capitalisation on market conditions and available supply.

The transition highlights a pivotal moment in corporate BTC ownership, with Twenty One Capital now positioned just behind MicroStrategy, which continues to hold the largest corporate BTC treasury globally.

Institutional Strategies Begin to Diverge

MARA’s reported sale underscores a broader evolution in how institutions manage Bitcoin exposure. Rather than adhering strictly to long-term accumulation, some firms are beginning to treat Bitcoin as a dynamic treasury asset, one that can be deployed to support liquidity, fund expansion, or manage risk.

In contrast, Twenty One Capital is treating BTC as a long-duration treasury asset. positioning reflects a different institutional narrative. Formed to act as a public-market vehicle for BTC exposure, the company emphasises accumulation and macroeconomic positioning. 

The divergence between these approaches suggests that Bitcoin ownership among public companies is becoming more dynamic. Rankings that once appeared stable are now subject to change as firms actively manage their holdings, while others are consolidating Bitcoin as a primary reserve asset.

Data Signals a Broader Trend in BTC Allocation

Available data from platforms like BitcoinTreasuries indicates that corporate BTC ownership remains concentrated among a relatively small group of public companies. However, the composition and rankings within that group are becoming less static. While exact figures can fluctuate with both market prices and corporate disclosures, MARA remains among the largest holders despite any recent reductions.

In this context, Twenty One Capital’s ascent is not just about one company overtaking MARA. It reflects a structural shift in how BTC flows between different types of institutional players, from miners to asset managers and holding companies.

More broadly, BTC is increasingly being integrated into corporate finance strategies not just as a passive store of value, but as an active component of treasury management. This shift is gradually reshaping how companies interact with digital assets on their balance sheets.

The rise of Twenty One Capital to the second position reflects how quickly standings can change when large transactions occur.  It also illustrates the growing role of specialised treasury companies in the digital asset ecosystem. Marathon’s move illustrates how even long-standing holders are adapting to changing market conditions and operational demands.

From now on, changes in corporate Bitcoin rankings may become more frequent as companies actively manage their holdings rather than passively accumulate. As institutional participation deepens, these shifts will offer a clearer view into how Bitcoin is being positioned within modern corporate finance, both as a reserve asset and as a strategic financial tool.
